What Is The Best Oil For For My Vehicle?

First take in consideration of what weight oil is recommended for my vehicle.Check Your owners manual for the correct weight oil.Next take in consideration the mileage and how well the engine has been maintained.

If your vehicle is a model year 2007 or later and it requires the new CJ-4 diesel oils, you MUST go with the Synthetic 5W-40 Premium API CJ-4 Diesel oil. If not a CJ-4 requirement and the engine has high mileage, say over 75,000 miles, and the vehicle requires a 15W-40 diesel oil, I would go with the Synthetic 15W-40 Heavy Duty Diesel Oil. If you have a diesel engine that has been maintained well or a newer engine, the best diesel oil is the Series 3000 5W-30 Hevay Duty Diesel oil. For engines requiring 10W-30 or a straight 30 weight diesel oil, use the Synthetic 10W-30/SAE 30 Heavy Duty Diesel Oil.

Has this vehicle used AMSOIL in previous Oil changes?

If using AMSOIL lubricants for the first time and the engine has over 10,000 miles on it, it is recommended you use AMSOIL engine flush prior to switching over to AMSOIL lubricants. Our synthetic lubricants have a lot of detergents in them to keep the engine clean. If you do not use engine flush first to clean out the sludge and other varnishes from using conventionl oils, these detergents will start cleaning your engine and deposit the 'gunk' in your oil filter decreasing its service life. Therefore clean the engine first and then put the AMSOIL lubricants in your vehicle so they can perform as they were designed to perform. You will need to use one 16 ounce can per every 5 to 6 quarts of oil capacity.
