Great for my 07 5.9 Cummins

I do one oil change a year on my 2007 Dodge Cummins, and this oil is just incredible. Probably a little overkill for the annual mileage but worth every penny.
Bottom Line
Yes, I would recommend this to a friend.

This oil is the best you can get. I trust it with all my engines which include diesel, gas and outboard boat. Can’t go wrong with their oil and their other products.
Bottom Line
Yes, I would recommend this to a friend.

Best oil out there. Better than Mobile one in my opinion
I put Amsoil in everything I own. People complain about the cost, but I can go 1 year+ between oil changes in my Duramax Diesel. People don't realize engines with turbos break down oils a lot quicker because of the intense heat (1700 degrees). Oil circulates through the turbo, Amsoil does not break down like other oils in that kind of temperature.
Have used Amsoil in my Dodge Cummings engine for seven (7) years. Maintains higher oil pressure at an idle than other engine oils. When having the injectors and valves adjusted, my mechanic tells me my upper engine is the cleanest he has ever see that has 228,000 miles on it. Rich Aubuchon owner
This is the only oil I have ran in my truck since the day I bought it - the truck currently has 267,000 miles of all this oil in it. Very pleased!
Bottom Line
Yes, I would recommend this to a friend.

Best 100% Synthetic Diesel Oil made

It is without a doubt the best engine oil made for diesel owners. The truck runs cleaner, cooler, and longer between oil changes. I highly recommend it! I have 260,000 miles on my Ford 6.0 without any oil-related problems.
Bottom Line
Yes, I would recommend this to a friend.

AMSOIL 15W40 has been the only oil used in my 1999 Cummins 6BT5.9 along with their filters. EVERY oil analysis from Blackstone has come back with zero negatives. I will always use AMSOIL products in my engines.
