      #1 for Jeep/Ram EcoDiesel
      By  JUSTIN,  a  Verified Buyer  from  Calgary AB  on  June 02, 2026
      Comparing this 5W-40 to Pen Platinum euro and Mopar MaxPro, the Amsoil product has the engine running 3-5C cooler on the oil and 7-10C cooler on the coolant. I have not had any reduced power from high temps under long hills or heavy loads when using the Amsoil product.
      Bottom Line
      Yes, I would recommend this to a friend.

      Best oil ever
      By  FRED,  a  Verified Buyer  from  1744 Brown Shop RD.  on  May 24, 2026
      I’ve been using Amsoil since 1968 on dozens of autos, RVs, and tractors. I’ve run it in all of them with extended drain intervals and never had an oil-related problem. I’ll always stick with Amsoil for anything that needs oil.
      Bottom Line
      Yes, I would recommend this to a friend.

      All great so far, Amsoil came highly recommend. I noticed an immediate reduction in engine noise. I put this in my newly rebuilt 642 Mercedes Turdo Deisel in a 2011 R350CDI. I do have a question though, my tech recommended making sure this Euro Spec Oil was for engines with a Deisel Particulate Filter system. Let me know about that, thank you.
      Bottom Line

      Only oil I use!
      By  CHUCK,  a  Verified Buyer  on  April 26, 2026
      AMSOIL is the only oil I have used in everything since 2008. Lawnmowers, Harleys, and all other vehicles. I I own and restore classic Mercedes Benz and currently have five both gas and diesels. The cars range from a 1983 380SEC with 230k miles to a 1990 420SEL with about 170k miles. The 1990 420SEL was a more recent acquisition and had what I think was a stuck piston oil ring as it was using about a quart of oil every 300 miles. I changed the oil and then drove it a 1,000 miles running about 75 mph the whole trip. I drove it 300 miles then fill the gas and had to add a quart of oil each time. After getting it to Florida (this car stays in Florida) I have ran four tanks of gas through it without having to add any oil. I really think the AMSOIL is what broke the ring loose as I did not add any additives. There is really no way of knowing if it was the oil, or the fact that I drove it so hard for that distance. Either way I will always use AMSOIL!
      Bottom Line
      Yes, I would recommend this to a friend.
