FYI: 1 ounce of oil equals 1.01 ( ~ 1) US fluid ounces

Interesting results!!! Love the new testing equipment!! Thanks for doing these!!!

Thanks Rich, appreciate the independent testing, now wonder what Pro Lube is going to say, you know they will see this.

These tests are valuable to the consumer. I know this oil additive testing series will save me money moving forward. I just ordered some Motorkote yesterday based on your test results and the results of others. I plan to use it in all my lawn/garden equipment and both my vehicles.

great testing. thanks again!

MotorKote always advertise they are the best additive I have seen some of these tests that show it does well I wouldn't use any of that stuff I just use schaffer and change at regular intervals

@FordBossMe, love the videos and the information you provide. Any chance you can settle the NAPA full syntheitc & Valvoline Full Synthertic as far as how different/similar the formula is in the future. Thank you

I just bought a bottle of prolube after watching their videos. Wish I would have seen this first.

@FordBossMe when you end up wearing that roller bearing out from all the testing. You should be able to use roller bearings from old diff/axle bearings if you have any laying around. Not sure if they will be as big as the one on there, but you might be able to rig something up to make them work. can save some money depending on how much they want for new replacement ones.

Just saved me $50, thanks

30 years ago the BG reps put on a demonstration at our dealer with a similar machine. Their machine utilized a beam pointer torque wrench rather than weights. They started with a sample of our bulk oil. The bearings seized at a low torque. They then tested their MOA additive. They were able to bury the needle with the MOA. As I mentioned this was 30 years ago so my memory may be off. I don't remember them conducting a third test where they added a percentage of MOA to our bulk oil. We became am authorized seller of BG products. We sold MOA, 44K and Supercharge. I'm now curious to see what the result of adding MOA to a motor oil will be. If it in fact fortifies motors oils like they claim. The MOA, by itself, showed the same result as the Prolube. Perhaps these additives are just "snake oils" that do not provide any added benefit.

I believe you have Prolube in one of your vehicles currently if I am not mistaken?. If so can you do a similar test to what Prolube did by taking oil straight off the dipstick from their finger to the bearing. Reason being is I am curious about heat cycles possibly having an effect but I also want to see if the results are the same or not.

MMO synthetic. Been using it for the last 2 oil changes in my 2020 Ram 6.4

Hi. Great channel. What’s your thought on using Ceratec?

Try motorkote and fr3 then mixed with triax 5w30 thanks for the demonstration

Interesting, and Schaeffers is a Decent Oil too. "CERMA OIL", The (only) Self Cleaning OIL on the Market. Wonder How that would work.

What is the psi on a main bearing? Obviously there is variation. But there must be a zone that bearing material can handle

Any chance you have an oil analysis on prolube? I'm curious what's in it.

I wonder what a 50% mixture would do? Then again the oil would be out of spec for the application which may cause other issues. Looks like prolube can only work with 100% concentration and is sold based on this fact but in reality it’s not effective at least based on this test. Great job in testing this product! Would be great if you could do a series on maybe the top 3 brands of oil additives out there.

A new toy and before Christmas 🎅

The valvoline oil on your first test performed better than the Schaffers oil didn’t it?

Weight Ounce vs Fluid Ounce

Need to mix i fluid ounce not a weight ounce to 1 quart ....... But probably wont make a difference!! It will be interesting what 5w - 40 does though!! Bearing burners are not optimum tests for oils in general. There is temperature and pressure to account for. But i do appreciate your dedication!! What do those bearing rigs cost these days??

That was on the Millionaire Morning Show on KZfaq.

I been using NMF Ionic Friction Reducer; for 3 years in my semi; synthetic oil was cleaner

Dumb question, did you thoroughly mix the Prolube with the Schaeffers oil I saw you poured it in, but I didn’t see you get mixed up🤷🏻‍♂️. Either way I’ve been using Prolube for years. I add 2 ounces per quart you have to be careful obviously because it’s a different viscosity. And I don’t run it in the winter months in Minnesota just the summer. #coldpourtest #amsoil

I run Delo xsp 5w-40 with stanadyne diesel additive. What would your dream set up be?

Motorkote up next?

Is redline still outperforming these other oils?

Try prolong. They did same test over 2 decades ago and they can lock it up putting their on strength on it.

Could you revisit and play with increased ratios? I'm curious if 2 or even 3 oz/quart will show better results. Just curious since it did so well full strength. Maybe Prolube isn't recommending the ideal ratio?

So with being this what it is, do you recommend using pro lube instead of oil?

Hello Rich, Appreciate all your videos, always great information. My 2011 F150 5.0 Super cab 2wd with 236K. Every 3,000 miles service with 6 qts Pennzoil Platinum High Mileage 5W/30 and 2 qts Lucas High Mileage Oil Stabilizer using Motorcraft FL500S filter. Oil is always clean with constant pressure. Thinking about changing to Valvoline Full Synthetic Extended Protection High Mileage MAX Life 5W/30. I run a JTL Oil Separator kit and average 3 ounces oil blow-by monthly. Appreciate any thoughts and recommendations. Thx John

Where can I buy a lubrisity machine like yours?

Where you get the. Prolube.

Marvel synthetic mistry oil that would be a good choice

There's a reason Prolube won't do this test on their channel. They did a mix recently but at 3oz per quart a d not at the ratio they actually recommend

For accuracy you should have the weights already on when you start the test because there could be variation in the time it takes you to put each weight on. If one has more weight on it for longer it will obviously have more wear. Also you are weighing in ounces. Fluid ounces are different than ounces in weight. Fluid ounces measure liquid in volume where ounces measures dry objects in weight.

Hey, I'm glad you got this machine. Could you test Kendal GT 1 MAX 0w20 oil.

can you test stp ceramic

Well i think the man said put as little or as much as you want 😂 dont be shy I'd say

Do a comperesion of Mahle OC705 and motorcraft 820s. And Mann-Filter W92045. These are for ford 5.4 - 4.6 engines. These are supposedly top tier filters German engineered. So if you can do a video cut them open and compare them

Definitely were dealing with childhood trauma slick, 50 did it to us lied to us we don’t want it to happen again

If a car takes 7 qts of oil and its non turbo will the oil mileage last any longer than 5k ? Does more quantity equal any more time between changes?

On the website it says for high mileage engines add 3 ounces per quart. Think that would do anything ?

Weight Ounce vs Fluid Ounce Is 1 oz liquid the same as 1 oz weight? This is where it gets confusing. Fluid ounces (fl oz) measures the volume of a liquid, or how much room this liquid takes up. Net weight (Net Wt) measures the mass of a solid, or how much the product weighs. Since fluid ounces and net weight measure different things,

Try X1R and RVS

Can you please test bestline

So your saying just use more prolube

Can you try a 10%?

The Schaeffer reps do this test to show how their oils "plate up" with their Micron Moly and antimony additives, and then completely prevents the machine locking up, but they will not use that oil you are using...instead they empty that modern passenger car oil bottle out and then refill it from one of their older spec diesel oils with more ZDDP, moly and antimony additives and sometimes heavier viscosity, and then you literally cannot lock it up. I caught a Schaeffer rep doing this and told him in front of everyone I wanted to use a sealed bottle of the modern, current Schaeffer passenger car oil, and he made a bunch of excuses and refused to test again from a sealed bottle. It's the ole one-arm bandit trick!

So will customers have the option to have their oil tested for a fee to see how their engine oil is doing?

Can you run the prolube by itself or is it too thick for the tolerances????

Prolube also states 3 oz for heavy duty use ….

Have you done this same test with other brands of motor oil, ams, valvoine ect?

Now do Mobil 1 and penzoil ultra platinum and valvoline side by side.

Now it’s time to test MMO Synthetic.

Most oil additives are not needed. You use the correct viscosity and a decent brand change your oil and do not run 10k 15 k 20k between oil changes you won't have a oil related issue.

Not sure why someone would not just buy a high quality fully formulated oil instead of adding some unknown chemical that could make one type of wear parameter better, but cause other issues with that now, mixed product that is not tested other than seat of pants or sounds. I would want to see a full oil analysis

im thinking you mixed it wrong it is fliud ounces . not weight ..you have to use a measuring cup to get the correct amount of additive i believe !

Is ProLube the new STP? The Fakers, I mean Racers Edge. If anything, they should reccomend a higher concentration of lube in the oil. They would sell more and it would work better. I think too much lube might be too viscous for a modern engine. Look at all the 0Ws out there. Good job, Rich. I'll never use it. Thanks.

I think finally I can trust Rich to give unbias oil test.

But the mix or blend might be a issue.

Did you really just use oz by weight to judge ounces by volume? Those are two different measurements, friend.

The best thing to do is not add anything to the oil and use it the way it came from the manufacture. In my 55 years of working on cars and oil changes, I waisted money on oil additives and learned not to add any now. The oils are too good as they come in the bottle. I started using Amsoil in 1976 and have only use synthetic since them. I have Amsoil or Schaeffer in my Harley, Pennzoil ultra platinum in my GMC 1500 and Mobil one 0w8 in my 2025 Toyota hybrid.

Oil additives are not needed and can damage your engine.

A true test would have the pro lube mixed . Put a rod in the jug and spin it with a drill . Do a real test

I’d like your content but you need to actually do the test and fluid ounces not weighted ounces the test is skewed because of that

Don’t use prolube in newer engines. If your vehicle recommends 5w-20 don’t use oil additives. Full synthetic oil is more than enough.

This guy is try to make them look bad you notice how he started the test dry and them he said I have to go sand the the machine back smooth so he made it so it would fail and he knows he did

Just a suggestion and not trying to be a di*k. The way it was mixed is not anywhere near consistent. Who knows if Prolube was even in the test. You should figure out the ratio in the testing machine and add Prolube that way to be fair.

Looks like snake oil!

Thats not an Engine.

Proves there videos wrong

Hey Rich would like to see you test Hot Shots Secret oil additive . Have been using it with positive results ! Thanks for all you do for us !……
