    Great for gas vehicles too
    By  Rix,  a  Verified Buyer  from  Northern Nevada  on  December 10, 2021
    Great oil for gas work trucks, I like the fact that I can go 15000 miles between oil changes, and thats driving part time in the dirt. The additives in this oil seem to help with cold starts when the oil has 5k or more miles.
    Bottom Line
    Yes, I would recommend this to a friend.

    Helping the overheating problem
    By  GILBERT,  a  Verified Buyer  on  August 31, 2021
    Had a overheating problem with my 2001 Dodge and I used the ams oil 5w30 synthetic oil and a water pump from a 6.7 and haven't had an overheating problem towing, I know this wasn't a complete fix by using the oil but when I used the thicker conventional oil I always had this problem so I highly recommend this product.
    Bottom Line
    Yes, I would recommend this to a friend.
