    Better economy, nicer cold starts
    By  EVAN,  a  Verified Buyer  from  BC, Canada  on  January 16, 2023
    Happy to be back on Amsoil with a new to me truck. Following an engine flush and the installation of Signature Series 0W20, the fuel economy is noticeably better and the engine sounds much better in the morning at cold starts. Not a placebo, I took the time to listen to the difference before and after. Moving on to a coolant change and transmission fluid now with Amsoil and see where that goes!
    Bottom Line
    Yes, I would recommend this to a friend.

    Top notch motor oil
    By  STEVE,  a  Verified Buyer  from  Texas  on  January 16, 2023
    I'm presently running this oil in 5 different vehicles, the 5-20 and 5-30 versions in 3 others, and the 15-40 in 2 diesel trucks. My '08 Ram 5.7 has 332,000 miles on it. This truck pulls trailers, hauls load, and general every day driving. The oil pressure gauge sets on 55-60 lbs. All but a couple of the vehicles have in excess of 200,000 miles, all on factory engines. NEED I SAY MORE??
    Bottom Line
    Yes, I would recommend this to a friend.

    The Good and not so good
    By  SIDNEY,  a  Verified Buyer  from  Colorado Springs  on  January 16, 2023
    I think and hear from everyone else that the oil and filter are the best around for your car. But, still don't get complacent, change your oil when due. I have asked several questions via the web site. I never get an answer. It doesn't work. It should be taken off the site or have someone actually answer the questions.
    Bottom Line
    Yes, I would recommend this to a friend.

    better in my car
    By  DAVID,  a  Verified Buyer  from  12822  on  January 12, 2023
    my sub forester was using 1 qt. of 0w-20 oil every 3000 miles. dealer said i didn't qualify for a top end rebuild. excessive oil usage was a problem for some cars; and was handled under warranty. i switched to 0w-30 signature AMSOIL.... the problem stopped. i have 96000 miles on my 2017 limited. i use maybe a 1/4 qt. every 80000-10000 miles ; after switching to 0w-30 signature.
    Bottom Line
    Yes, I would recommend this to a friend.

    Nothing Better
    By  AUSTIN,  a  Verified Buyer  from  CA  on  January 11, 2023
    Hands down Amsoil has the best oil and oil filters out there. I always use the engine flush first and then do the oil change after about 15 minutes of idiling. Then I change oil and filter, and even after the first oil change I did with the Amsoil products it was like my car was a new car. Now I drive about 1000 miles a week commuting to and from work and I used to worry about my car not making it one day but now with this oil I don't even have the littlest worry anymore. Will be changing the oil every 3000 Miles for the first 3 oil changes just to get my engine back in great condition and fully lubricated. After the first 3 oil changes I'll go to changing it 3 every 5000-6000 miles and I know now it will be completely fine. I've used all the best oils out there like motul, liqu-Moly, Royal Purple, Red line, Pennzoil platinum, and any other premium oil you could think of, and hands down nothing compares! Thank you AMSOIL! Nothing but the absolute best.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil for the 6.4 hemi
    By  Tree Trunks,  a  Verified Buyer  from  New York  on  January 06, 2023
    Was trying to find an oil with the weird chrysler spec which only the oem oil had not sure about these days but at the time amsoil was the only aftermarket oil that can reach this spec, but specifications or not this oil is of very high quality here in ny where it can get to be below zero and using other oil brands notice some valve train noise which is common but not welcomed I have to say I've never experienced this when I started using amsoil and as the old saying goes an ounce of prevention for a pound of cure
    Bottom Line
    Yes, I would recommend this to a friend.
