I appreciate all the hours, days, weeks and money spent in all your videos to either entertain us, educate or both all composed in a 10 minute video

Being in climate that regularly hits -40⁰ F in winter, I'm always interested in the cold weather performance.
So thankful for all the work you put into these tests.

I think it would be very interesting to see a comparison of OEM oils (all the same weight) such as Honda, Mopar, GM, etc., maybe with Mobil 1 or something else thrown in as well. There are some folks that are religious with using OEM oils when it probably isn't necessary.

We must protect this man at all costs. Thank you sir for your unbiased and thorough videos.

I think every manufacturer needs to strive to get the “Project Farm Seal of Approval”

I work at an auto parts store, so these oil videos and other car related ones have really helped. I recommend the 3M headlight restoration system all the time thanks to you. So, thank you for helping me help my customers make an informed purchase 😊

Your testing methods are some of the best out there. Many times I have referenced your videos when picking certain products and so far I have not be let down!

You do such a great job, and you don’t waste the viewers’ time with a single extra word. You get all the information out very quickly and concisely. Your time and eneregy and knowledge are much appreciated.

Your motor oil tests have been incredibly thorough and informative. Better than anything on the internet and have changed my buying habits. I would love to see oil filters next as there is so much marketing material out there but no true head to head tests. Thanks for everything you do!

How many other people are here using Project Farm as a gauge for what to buy and what the difference between stuff is? 😅

[Jeremy_Fielding]

I have been using Mobil 1 for many years now at the suggestion of a mechanic. Literally every time I go buy oil I have these two questions about SuperTech vs Mobil One given the price, and high mileage vs regular! Thank you Sir.

Hi there! I happen to do laboratory testing on rubber compounds as a career. I noticed when you were testing the hardness of the rubber tire chunks, you left the durometer on the pieces for some time before concluding the value. If you want to get a value that might correlate more closely with other laboratories, ASTM procedure is to press a Shore A durometer (the one featured here) into the specimen and record either the maximum reading or the reading after one (1) second under 1kg (2.2lbs). I’m really sorry if this comes off as condescending, I’m just a fan of the show and it’s exciting to see my job’s work done here.

I would love to see a compilation with all your previous oil test results compared on one graph/chart. Always great content, thank you!

[CarsSimplified]

The thorough approach down to the little details like swapping the pots in the same order every time is always impressive. The regular Mobil 1 pouring out so slowly was pretty weird, but given that it happened twice, I can't imagine it was any sort of mistake on your end, especially with the track record you have. Another fantastic Project Farm video!

Been using Mobile One high mileage in my 2005 tacoma ever since it hit 75, 000 miles. Its been a great oil. I've got 270, 000 miles on it now and it doesn't burn oil and no leaks. Hoping to hit 300, 000 in a couple years. Thanks for the great videos. Trust project farm above all the "consumer report" companies.

I'm always interested to see reviews on Super Tech products as they're what I always use on my vehicles, simply because of the affordability. I regularly drive over 3k miles in a month in my personal vehicle and have to do oil changes often to keep it running smoothly; In the 6+ years that I've used ST oil and filters across several different vehicles and thousands of miles, I've never experienced any issues that could be traced back to or blamed on inferior oil quality (knock on wood).

This channel is truly a blessing since I’m just now working on my tool set out of tech school! I watch every video and I am amazed by the actual effort and time put into each and every video, It’s insane! Don’t know if you’ll see this but hope you had a great thanksgiving and thanks for giving us great content!

As a bottom feeder in the car department with cars above 150k I've always wondered this. You add a lot of value to the curious community. Thank you!

A cool test would be diesel oil vs car oil. Diesel oil doesn't have to protect a catalytic converter and its additive package is very robust to handle soot and high demand diesel engines. Many of us use it in small engines vs the cheap gas engine oil. Great video as always!
