Have used this product since 1997, and still impress with it. Do oil change once a year (approx 25000 kilometers per yr) send an oil sample to Lab and return are excellent. Highly recommended

I have been using this engine oil in my Diesel Pusher Motor coach for 10 years and would not use another oil. I also have the Turbo Drive automatic oil in Allison Transmission and because this transmission is not only very good but it is an expensive one that I only want the best oil in it.
I actually replaced the recommended Castrol Transynd oil that was in it to this Amsoil one and noticed that the shifting is smoother and the temperatures are lower during use. I monitor all the engine and transmission activity thru a computer while driving so I actually am seeing what is happening at any time, so, these issues I see and not only feel.

I have been running this oil for 15 years in my 2005 superduty 6.0 diesel. This truck pulls a 16,000 lb fifthwheel many miles a year. Engine does not use any oil, have not had any injector sticking, and no turbo coking. Great customer service and lighting fast shipping.

Have been running in 04 duramax 3/4 ton for 100,000 miles with regular oil change intervals between every 3500 to 5000 miles in a work truck that has towed heavy loads or been under stress for most of its life. Switched to synthetic amsoil at 65,000 miles in engine, plus transmission and all the boxes. Has 179,000 + miles on it now and is still running and working strong. I believe the amsoil and regular oil change intervals has made a difference in the longevity of trucks power train components.

Have used this oil in my Duramax since it finally broke in at 70,000, I now have 255,000 on it and every oil test came with 50% oil life after 10,000. I do a lot of short trips along with really long trips towing.
