I would have done the oil change, ran without Amsoil for 15 min drained a cup or so, poured the amsoil flush in ran for 15 mins and compared the two samples. Thank you for taking the time to make this video I would still say it works!

This is an interesting test. One thing I've picked up on over the years with the engine flush is to get the engine hot before you do the flush. Amsoil Dealer came up with the idea and to me it made a lot of sense they claimed it cleaned better. One thing I always do is put a fresh filter on when doing a flush and they usually come out very heavy after draining the oil like they caught a lot of contaminants during flush. If you are wanting to keep that engine clean just run Amsoil in it, whatever the flush doesn't get the oil will in due time. Amsoil is far superior to most motor oils I would never use anything else. Anyone that has documented long term use in one engine with Amsoil comes up almost fake like results when the engines are broke down. More testimonies are popping up but a lot of them are untold on youtube, the oil has been around along time.

As an AMSOIL dealer, running brand new oil in an engine that has any sort of mileage on it will come out darker. This is not an indicator of how dirty the oil is. I've actually sampled oil which held engine flush in it and the feedback from the analyst did not show any abnormalities. IMO, the only real way to know how well this works would be to pull a valve cover and see if previous sludge buildup is now diminished. Engine flush is a good product, as its a high dosage of cleaners. Doing this same test with a cheap synthetic may yield better results. People just buy into tests like this as if they are valid. Do your maintenance, flush as needed, and your engine will run long and strong!

Great video!! I'm an Amsoil dealer and I've been hoping someone would test their Flush like this!

I’m a Preferred Customer with Amsoil and I love their products. Been using them for 2 years now and I have switched many friends and family over to Amsoil. They all love it too. Thanks for the comparison!

I'm an Amsoil dealer and I'm happy see someone test this product thoroughly

Great video, I used the engine flush on my car before switching to Amsoil. I was wondering how much sludge it removed & this pretty much answered the question

Good work showing these visual results! I've been using these AMSOIL products myself on various autos, I believe it works very well.

It is good to see a review like this. I find it reassuring the cleaner is backed by Amsoil. I am certain they have more access to information on this subject than me. And expert information from engineers who study this their whole lives. I will be purchasing this product soon. An old guy who ran a small station back in the 1970's told me right before an oil change he would add one quart of transmission fluid to the oil. He would drain some out if he had to. He got the idea when someone showed him it would clean greasy oily hands. So he figured if it could clean the gunk off his hands, it could clean the same gunk inside the engine. He would then run the engine on short trips for a few days then change it. I started doing it every other oil change. Once my old Dodge had 60,000 miles it used a wee bit of oil in 5,000 miles so I just added whatever it was low. If it only took a half quart, okay. It was doing the job because at 100,000 miles I pulled the valve covers to install new gaskets and it was spotless in there. NO SLUDGE at all. At about 150,000 miles the oil pan starting leaking so I removed it and I was amazed by how clean the pan was. Again NO SLUDGE. The van had about 190,000 miles on it when I parked it and started using it for storing things. She starting rusting out the floors so I wasn't sure it was safe to drive. So the trans fluid cleaned the engine and did not shorten engine life because it ran perfect at 190,000 and I wasn't using synthetic way back then. Had only slightly heard of it but it was way too expensive back then. I live ten miles from the nearest city so the engine always got a good heat up before it was parked. That might have helped keep the engine clean but it was mostly the transmission fluid because I would check the oil on the dipstick and I could see it get darker in just 50 miles of driving after I added the trans fluid.

That was the best test I have seen so far. Thank you

Do the EXACT same test, except minus the cleaner, let me know how that oil looks....

Great video. My vehicles are 100% AMSOIL. It's night and day difference from dino oil too 100% synthetic oil. The flush does a great job too! I have a 5.9 Cummings with almost 400K miles and I use the flush every oil change because of the suit from the exhast. I have gone 25k miles with the oil. I have a oil bypass system plus the AMSoil. Very cool! I also have a 2012 ram that is still factory... Not deleted on a 6.7 Cummings. I can go about 15,000 to 18,000 miles between oil changes. I'd go longer but there gets diesel fuel in my oil because it's always doing regeneration of the DPF. Darn EPA!!! Again, Great video!

Awesome idea for a flush comparison. Thanks for doing it. 👍🏻

I'm glad you put this video I'll. Although I have used AMSOIL flush as nice to see someone actually complete the process would clean oil.

Great test and yes all amsoil products are great I use it on both vehicles also preferred customer

You sold me on the stuff. Can't wait to try it. Thanks!

Great job on oil flush .... Using transmission fluid as a engine flush is cheaper and just as effective .... I pour 2 litres of diesel fuel into a engine after draining oil then put the drain plug back in and pour in diesel fuel to help clean bottom of the engine oil pan. I then pour cheap clean oil in and run engine and drain it to help clean out residual diesel fuel and drain this oil into a clean pan and use the oil in a older vehicle as top up oil It just cleans the oil passages it is a extra step but if your ocd or like clean engine oil it works to clean sludge I have experimented putting 2 litres of new oil 1 litre of transmission fluid and 1 litre of diesel into a engine and running it for 30 minutes even driving it around the block then changing the oil and it really cleans out a engine it stopped the stuck valve noise on start up which had noise valve train noise on start up ...

After watching this I did the exact same thing on my rogue when I changed the oil. All I can say is that it works great. the oil came out black as coal when I flushed it. Stuff does a great job. Not sure if its better than any other oil flush but either way it works

Excellent video. The only other Amsoil videos I have seen were projectfarm and from Amsoil dealers. I have used Amsoil in my chainsaw but never in one of my vehicles

Awesome review and experiment, thanks!

I agree with Daniel... your also getting remnants of the previous oil that wasnt fully drained from previous oil change!

Good job. Im not surprised. I run amsoil in my 15 5.0. Im going to do this flush today before my oil change. Truck has almost 100k, got it with 50k and ran amsoil sig from day 1. I would like to think the amsoil oil has cleaned the engine alone over that time, but im doing the flush anyways, i figure it cant hurt and I plan on running this truck until the wheels fall off. Thanks for the time and doing this comparison. 👍

This is exactly what I was looking for. Thank you. Top class

Good to see you have the most important component of the flush. A Timmys.

Wao I use AMSOIL flush the first time the oil come out black that stuff is real 5 star thankyou for the video

Thank you for your effort. Great video.

Brillant video,Thanks for sharing this!!

Awesome video.. i was debating to get this.. now for sure I'll do a flush out next out change.

This is a great effort. Like several of the other viewers, I would have liked to have seen what the plain Valvoline after 15 minutes, then the Valvoline + AMSOIL product after 15 minutes looks like.

Im not a dealer and not paid by amsoil and not given free products. Purchased all with my own funds. Using amsoil since 2005 in a 2003 2.4L Camry. Extended drain intervals have been used since I bought the car in 2005 with 42K miles. I have used the amsoil engine flush each year before I change the oil and I only change the oil every 15K miles or 1 year... whichever occurs first. Car now has 141K miles on it and I am still driving it as my commuter to work on days with good weather. Working 24 hr. shifts at the Fire Department I have an 82-mile round trip so roughly 10,800 miles per year just driving to work. Back in 2006 I was commuting to KC and put over 20,000 miles on one oil change on the Camry halfway through I changed the oil filter topped off oil dip stick and good for another 10K miles. That was back before amsoil came out with the better 15,000 oil filters and yes this is the same Camry I am still driving today. After that the car sat for a few years not driven much but she is out of the garage and back on the road now. So, engine flushes have not hurt me at all so ill assume they have helped eliminate sludge but would have to tear the motor apart to 100% verify and really no reason to at this point. I should be good for another 100k. I currently have 15,000 miles on the current oil in the Camry so its ready for another oil change and filter. I also have been using amsoil in large zero turn lawn mowers (6 acer lawn) Honda 1132 snowblower, arien’s 724 snowblower, etc… just purchased a 2014 Silverado LTZ Z71 with a 6.2L with 67K miles and ill switch to amsoil soon there as well. For the record i only used engine flush in vehicles and not the smaller engines

Nice Video! I like Amsoil products, and the flush I believe it can works, but only for not solid carbon deposit. When you finish this procedure, don't forget change the oil filter again.

Well done! Very helpful.

I want to see more of the M3! This was a good in-depth video. I did something similar to my BMW and it rides great!

Very good expirement. Thank you so much.

Good Job, I'm buying one this weekend

I think you proved that the Amsoil flush is effective despite some minor issues with methodology. When you ran the engine at 6:50 there was obvious engine knocking. I am interested in what oil you finally put into the engine and if there was any obvious sound difference especially if your final oil was an Amsoil product.

thanks for the test. It was good.

Finally! Someone who has done it the proper way.

The 1st oil change will always have crap in it because there's always dirt in some area's inside engine. Great effort and sure it did some good.

Anywhere from 10 - 20% of the oil in your engine remains after a standard drain and refill. These modern engines have overhead cams with multiple galleys, VVT, coolers and the main oil galley and pump. What you saw come out during the Amsoil flush is the new oil with 10-20% of old oil. I have done this many times without a flush. What you should have done was drain and refill a second time to get a 99% oil replacement, and then add the Amsoil flush and compare. For sampling oil, use a blank business card paper stock, and place 2 drops of oil on it and let it stand for several hours. Repeat with the oil using the flush. You will be surprised. When I do this the oil in the engine stays nearly as clean as virgin oil for the first 500 miles, and much cleaner compared to just a drain and refill at 15 miles. I have oil analysis that shows the retention of wear metals, depletion of additives, loss of viscosity after a simple drain and refill. I use Amsoil products for 30 years. Most people assume that a drain and refill gets all the oil out, it does not. Would any buy a jug of oil that says it contains up to 20% used oil of unknown quality, and may contain wear metals, fuel dilution and sludge, and use it for a full oil change interval (5-7K miles)? I don't know anyone that would. Make another video and complete the 99% flush, then add Amsoil and do the two drop paper test.

Did you cut open the new oil filter that you installed during the flush? I’m curious if it was full of slug or not. Although it appeared your engine was taken care of and was fairly clean.

Adding a flush to clean oil. FINALLY a guy with a brain to do a real test. Kudos. 3:35 if you have a drill, drill a small (very small) hole in the bottom end of the filter. Just be quick pulling the drill back. Turn the oil jut so the spout is up, not down. pours better.

Just saw your video and wanted to ask what was the platic you were trying to use under the oil filter? Have a Ram 1500 and tryong to prevent it from spilling all over the car and the tool you were trying to use looks like something I need to look into for this. Thanks in advance.

Great video...thank you brother

Oh it works. Used it many times in different vehicles. Sometimes it works too well. Washes a lot of junk into the pan if its there. Can clog the oil pump intake.

Always put the fill cap back on, so the PCV system works correctly.

Good video! The first oil from the initial oil change could have been a bench mark too.

Great video thanks!

Awesome video! I knew that amsoil stuff is good. I put signature series in my Ford and runs like a champ.

I appreciate you doing this I’m subscribing

You didn't point out the original color of the Amsoil product. But I watched as you poured it and it looked pretty clear. If the original product was dark in color that would "color" your results.

I guarantee you if you didn’t add the Amsoil engine flush, the oil would still look the same darkness. The reason is there is quite a bit of old old left in the engine, lines, pan, etc. Try this: do 3 oil changes back to back with cheap oil after running 15 minutes each time. If the final oil change comes out as clean as it went in, then add the flush on the 4th oil change. That’s only true way to see if the flush works?

Great video 👍.

Of course it works it’s the best stuff in the market and closer to real synthetic than any others and Valvoline is excellent oil as well

Great video

Was the used oil actually less viscous or was it still hot when you compared?

Good video!

Good video! Amsoil flush doesn’t require new oil and filter though. Just do it before the oil and filter change each time should be fine.

I'm trying this stuff next time on my next oil change I'm convinced because I brought an 02 IS300 with currently 162,XXX miles and this stuff is probably needed.

If you gonna run a thin flush in some new oil, bump up the viscosity one tick. So if it is supposed to take a 5W-20 or 0W-20, bump it up to a 5W-30 or 10W-30. If it calls for 5W-30, bump it up to a 10W-40. And even though it says to just idle it, I put something to hold the throttle at 1500 rpms for 30 mins, or I go out and drive it normally for 30 min total. No heavy-footed acceleration or high rpms, just normal driving on some country backroads. I often do some induction cleaning on the top end at the same time since I'm changing the oil and filter out afterwards anyway. Might as well clean the combustion chambers and valves at the same time as the crankcase and piston ring lands, making good use of that inexpensive oil and filter. If you use highest quality oil and change it on time, you could avoid the need to run a flush or induction cleaning.

Try to drain the new post flush oil to see if it'd still be dark because of the deposit on the oil pan that might be still present?

Synthetic oil protection on KZfaq posts bunch of videos about Amsoil, you should watch some of his, I enjoy his Chanel very much

Very cool video, i am a fan of amsoil products. However, there is one flaw and that is the fact that oil color does darken after it has been heated. Very black oil is what you would be looking for because black oil contains soot. On the other hand I am not sure how you could test this with a short/less time consuming method. Best way would obviously be to view engine internals before and after use. Issue with that is not many people have that much time. Especially if you have an 8-5 job or even longer. Good luck in your testing methods. Subscribed👍

Good video thanks!!

Amsoil is amazing.

With fresh oil it hasnt been ran with the heat of the vehicle try it like evryone is saying run it with fresh oil drain it and do ur flush c if the color change is the same if so wat did the flush actually remove??

Great video! However I wonder - could the dark color of the oil darken because of the temperature of the engine or some leftovers inside? In project farm channel when he does oil test when he cooks/heats the oil - it changes color towards (darkening the oil). Dark oil is not necessarily contaminated/dirty but I suppose it could be. It's not a critique but just my thoughts. After the flush did you noticed a change in engine working - e.g. quiet, smooth working or any other difference from before? I love these kind of experiments from honest people! Thank you!

Very good comparison. What color is the flush fluid?

how many mileage do you thing would be adequate for a flush?

Amsoil has some good products but FYI That oil is a Conventional blend I always use full synthetic because u could be at risk of oil leaks... great video though!!!

Great video. Any plans for running the flush for longer then the recommended 15 min when u do your other truck?

I like your video just want to say is the cam phasers don't actuate at idle so the oil galley on one side of the phazer never gets fresh oil to it. I have had to take the plugs out of the bracket to clean 1 time. The shop it was at had just put a brand new head on it and burnt it up from not having oil.

Impressive. 👍

Thanks

Huh!! It looks like you had a VERY small amount of varnish, but no real sludge build up. Shows you've been getting oil changes on time. I've used the Liqui-Moly ProLine Engine Flush on some Hyundais my friends own (conventional 5-6k mile oil changes) and that stuff came out tar black. After use, you can tell the engine runs smoother now that the oil passages have been cleaned. I'll have to use the Amsoil flush myself on something, but by the looks of it, it works pretty well. Did you look in the valve cover after cleaning or was there a plate blocking view of the cam sprocket and timing chain?

There is a guy on YT that did a test to see how many oil changes back to back it took for the oil to come out the same color as it went in. I believe he idled the engine for 10-15 minutes between changes. I believe it took 5. At that point, I would have done the oil flush to see what color it came out.

Good video

No way your back!! are you still keeping fish??

I don't think you can jump to the conclusion that it worked. Despite dropping the old oil, there is still some residual old oil in the engine no matter how long you let it drain. When that residual oil mixed with the new, of course the next drain will be darker than new oil, fresh out of the jug. But I admire your idea to test, rather than take the word of Amsoil marketing. I am not knocking Amsoil, I think they are probably the best, but not sure of your method and conclusion.

Great video, thanks! Was surprised you ran the engine with oil filler cap off/open & funnel inside! It all worked out tho.

My 2.0 VW Jetta used to use 1-quart every 3000 miles. After the Amsoil flush it's reduced 75%!! Awesome stuff.

Excellent 🏁🏁🏁

Works for me👍🏻

How often should I engine flush?

I got that same oil drain pan from Canadian Tire, threw that screen right in the trash. If I drop a bolt in the pan I fish it out with a magnet, which will still be better than oil all over my floor.

Do you manage an Amoil group on FB? Past dealer and current customer for 30 years.

Lube Guard heavy duty flush is about the same. I change the filter and run it another 15 mins.

Nice video so if i purchase the amsoil flush do you recommend it flushing it with the old dirty oil then draining the old oil plush the amsoil flush then new oil then drain then new oil ?

I am planning on doing the same with my wife's Audi TT but using Liqui Molly engine flush. Once it gets warmer in NJ that is. Here is the plan: Step 1) Old Liqui Molly oil + engine flush Step 2) New oil - cheapest 502/505 approved 5w40+new filter+engine flush Step 3) AMS Oil European Formula 5w40 full SAPS oil + AMSOil filter. Note: may be repeat step 2 twice, TBD on the condition of what is going to come out.

What’s the update? Running strong??

I highly recommend using Amsoil oils as well. Change your oil every 6 to 12 months. You will get what you pay for and its long engine life.

How did it run before and after. Engine noise. Drivability.

Running without the oil cap on the motor makes a difference because the oil pressure is not enough to push the oil through every crevice.

Not a bad test. The only thing I would have done different would have been to first plush it with new oil. This way it would have picked up any residual oil that is still in the engine. After that I would have changed the oil again and then do the flush like you did.

Aquatic logic! Love you videos mate. Problem though: 4:49 you can be seen putting in 5w20 oil in your Ford Focus but at 5:43, you can been seen putting 5w30 into your Ford Ranger's engine. I'm not engine scientist, but mixing oils can cause catastrophic failure (cratering cylinder, premature engine failure, etc.). My daddy mixed oils in his basement, even though those were CBD oils, I know my oils. Keep an eye out for that buddy. Love you

Unfortunately, assuming dirty engine oil means the product cleaned isn't good enough. I accidentally poured a brand new jut of Mobil 1 into my Suburban and ran it for a minute. The oil was the wrong weight so I drained it. It came out as dirty as any oil change I've ever done.

Great video man Go Canucks Go

The oil left in the engine’s oil galleries will contribute to darkening the fresh oil + engine flush. A better procedure would be to 1) drain oil change the oil/filter and run for 15 mins, 2) drain oil and change oil/filter again! this time adding the engine flush, run again for 15 mins 3) drain it, another new filter and add oil of choice. If the engine oil on 3rd drain comes out as dark as your video then the engine flush has truly liberated the solids from the crankcase. Further, most oil filters hold a half a quart of oil so it has to be changed out whenever the oil is dropped as per above.

You should look at the AMSOIL EA oil filter. The are capable of lasting from 15,000 to 25,000 miles! I have done that for over a decade....

What color is the Amsoil going in? That could be everything right there.
