Laundry detergent please! You could test for oil, grease, grass, dirt, ketchup, sharpie, etc. Consider your audience, we need this!
-
It’s 3 am. I don’t own a diesel.
-
It’s so crazy how oils with the same viscosity rating act so differently in different temps. Especially the cold temps! Thanks for your great videos!
-
1:41 Thanks for emphasizing that -40 degrees does not need a descriptor, as it's where both Fahrenheit and Celsius scales converge. Another great video as always.
-
Project Farm is still the hardest working channel on YouTube!
-
I don't have any diesel engines. But oil testing is always fun to watch!
-
I am a mechanical engineer with autism and OCD. This is by far my new favorite YouTube channel.
-
As a motorcyclist that uses T6 and T4, I'd love to see them pitted against purpose made motorcycle oils.
-
Do I own a diesel? Nope. Do I plan on owning one? Nope. Did I watch the whole video? Yep. All your videos are so well done and very informative! Thanks for your work.

Rotella's price to performance ratio is why it's so common in fleet applications. It's not the best, but it keeps costs low in an environment with controlled service intervals. Consistent, regular oil changes are more beneficial than any additive package that exceeds OEM requirements!
-
I love how your videos are thorough, objective, and fair for each test you do! Thank you for your contributions to this platform and to all of your everyday views.
-
All of your videos are so amazing. I've shown so many of my family and friends your videos. They are so well made and informative. Thank you so much for all that you do

Shell Rotella only in this household. Two Kenworths, three John Deere field tractors, two Kubota tractors, three diesel pickups. All run this oil for years with no problems. Change any oil when you should and there will be no problems. We always change before the recommended time interval.
-
Would be nice to see you test multimeters, checking voltage, amperage, and resistance accuracy, seeing if the cheap $50 multimeters are as good as the more expensive ones
-
Watching your awesome videos from India! I own a VW 1.5 TDi diesel engine and had been running Liqui Moly Toptec 4100 for the last two oil changes. Recently shifted to Amsoil Euro 5W40 mid saps and can definitely feel the NVH improvement and much better power delivery. I’m happy to see the results in your testing!
-
Our whole semi fleet switched to amsoil and we've seen 30% less repairs with millions of miles tested. Use to run rotella like every shop but the results have been speaking for themselves. Great channel!
-
Canadian here. The cold flow with the Hot Shots was WILD! Thats a game changer for winter diesel starts, especially in Powerstrokes with HEUI injectors that need oil pressure to start.
-
When you go onto some diesel forums, the folks will often swear by Rotella. Nice to see this test show Rotella's performance much more objectively.
-
I use Rotella T6 in my diesel truck. Your testing showed to not be the best, but it also showed it to be very good and affordable. Good enough for me.

Very impressive test. Well worth watching. I drove a fuel transport for 20 years. The oil company I worked for sold many different types of engine oil. Including most of what was tested. We were a Schaffer oil distributor for 70 years. That was the oil we used in all our trucks. I watched a teardown of a Detroit 60 after 1 million miles. Very impressive results.
