The Best Engine Degreaser??? Gunk vs Walmart vs Motor Medic vs CRC and More...

Рет қаралды 198,228

In this video we answer the question who makes the best engine degreaser. Here are the brands we will be testing. Gunk Original, Gunk Foam, CRC Pro-Strength Degreaser, AutoZone Engine Degreaser, O'Reilly Engine Degreaser, Walmart SuperTech Engine Degreaser, and Motor Medic Engine Degreaser.
We are going to subject each engine degreaser to multiple tests. First a dirt removal test to see how much grease each product will remove. Next we are going to test how the degreasers react with aluminum, rubber, and paint. This will tell us how harsh each of these engine degreasers are.
Here are links to the products that I used in this video:

Motor Medic doesn’t sell that degreaser anymore. It’s a rebadged can of Gunk original. It was cheap because there’re just getting rid of inventory. Anyways I looked up the MSDS on the Gunk original and it’s pretty much 90% Diesel and 10% Kerosene.

Great report, Repair Geek! Excellent research as far as I can tell. Keeping as many parameters constant as possible, comparing performance objectively, and ranking on price if needed. Well done. I am so grateful! And telling how it is, i.e. using just diesel and kero to improvise, proves you're not tied to any manufacturer or brand! Really rare these days, hope folk recognize this! I, as some others, of course, we all would want to see more: e.g. how do these products perform on "baked-on" oils and grease. Hey critics: if you don't find people who do it for you, why don't YOU do it and publish your results? Merry Xmas, Matthias.

Excellent video and I like how you tested more than just the effectiveness of the cleaner but also it's effects on different materials that it may come into contact with. That said, I'd like to address a couple possible flaws in your methodology. First, I would have primed the test pieces and allowed the paint to fully cure in order to more accurately simulate an automotive finish. The difference in hardness and adhesion between a one day old paint job and a one week old paint job is staggering. In all likelihood, none of those degreasers would have even dulled the gloss on a primed and cured paint job. Second, I would have followed the manufacturers instructions for the use of each product. Settling on a 5-minute working time for all products really only makes sense if the end user is the type of person who's going to let it sit on there for 5 minutes, regardless of what the instructions on the back of the bottle say. Those people are dummies and I feel safe in saying that because they're not here. Anyone watching this video is going to follow the directions on the back of the bottle. That's why they're here, they're intelligent, inquisitive and they want the best results. Third, I would have baked on the grime slurry. That stuff's not hard to remove just because it's inherently sticky or sludgy, it's hard to remove because it gets baked on. You don't have to hit it with a blowtorch, although I suspect that would remove a good deal of it in itself, but a couple 1 hour sessions in the toaster oven at about 200°F would have really done the trick to get it good and stuck and would've more accurately represented real life under the hood conditions. Again, great video. I look forward to hopefully seeing an updated version of these tests.

B12 works but evaporates so fast and not trying to poison yard so something like SG or Dawn be ideal. Either way TU for vid. Thanks! ...edit Dawn ended up working best as initial cleaner. Have to brush using small fingernail like cleaner brush and toothbrush but want it as clean as possible before teardown.

You guys are missing one important detail , yes these degreasers have diesel and / or kerosine but they also have an emulsifier so that they will disperse or can be “rinsed off” with water. That’s why it turns white when you rinse . Not sure if they still sell it but Gunk used to sell a concentrate that you could mix yourself with solvent or kerosine or diesel.

nice job, very informative. I wonder how simple green and purple power would fair in these tests. Those seem to be the main ones not tested. I also use hot soapy water (with degreasing dish soap), no way this can hurt the rubber, plastic and metal parts. Thanks for your efforts 😊😊💖

I really need to clean the entire engine bay and undercarriage of my 1st Gen and you just confirmed my thoughts. Star off with the kerosene/diesel and let it soak for few minutes.

@FreedomLovinLady Жыл бұрын

@@katiedotson704 I cleaned my 1st gen Tundra engine bay a couple of weeks ago and used a process similar to the Chris Fix method (he has a good video on it) to make sure I didn't hurt anything. It's not complete as I had a leaking valve cover gasket that has since been fixed. Mostly I used the warm soapy water so far, but now I'm going to go back and finish getting the oil from under the valve cover area and down to the manifold. I'll use a degreaser and then warm soapy water to get the bottom areas. I cleaned all the items I could reach, painted areas, plastic, and metal and then shined each one with non greasy plastic protectant, waterless paint wax or a bit of Mother's chrome silver polish or a wire wheel (each cleaner to its intended area) ... and the results are very nice, it looks so much closer to the engine I remember from back when it was new. No mechanic spills or road grime, it's not perfect but wow it looks so much better. Next time I'll get some longer reach brushes to get the parts out of my reach. Us girls have to work a but harder to get to everything under the hood it feels like, but that's OK, a reliable and great looking truck is worth it. I even replaced the cold air intake system and cleaned the throttle body while I was in there and will be replacing the spark plugs this week. 149k miles is just warning up for a Toyota 🙋‍♀️💖😊

@@FreedomLovinLady My 30 yr old girl just turned over 300K. I rebuilt the starter last year and at this point I have the alternator on my bench. I should have already had it back on but the thought of scrubbing, sanding, and painting it came to mind. I had almost talked myself out of it til I found out there is a paint color called Cummins Beige. Now, I couldn’t turn that down. Then one thing led to another. I don’t know if others think it’s a good idea, but any time I replace or repair a part that is external to the engine, I use a paint pen and write the date and mileage on the part for future reference. I’m changing the interior color and am planning on taking the dash cover out to paint it after alternator gets back in. I’m trying to talk myself out of painting valve cover but I’m pretty sure I know how that’s gonna go. You wouldn’t happen to know where I could get a Truck Bidet for a reasonable price, would you? 🤷🏻‍♀️

@@katiedotson704 wow 300k and 30 years on the road, that's great, writing the dates on parts sounds like a good idea, i also keep a file of reciepts and write notes in the toyota maintenence book that came with the truck from the factory. you might get the valve covers powder coated instead of painting them, it's supposed to keep temps under the hood down more and help efficiency (plus it looks looks way cool and protects the parts) my next big project is to get the roof painted before summer heat sets in, an injury a few years ago got me behind on polishing and waxing, so i must repaint the roof before it decides to chip or peal which is way worse than just having worn down clear coat... oh well, nobody is prefect and the truck still runs crazy good 😊🙋‍♀️💖🥳🇺🇲
