I'm thinking about changing over to synthetic oils in all applications in my vehicles. How many of you out there run synthetic and what brands do you use? I was reading the Amsoil advertisement on forum and it all sounds good, but all advertisements can sound good but not all perform. I only run about 10,000 miles a year on the truck and wifes Jeep even less. By the way truck is '02 CTD with 64,000 miles and wifes jeep '07 with 6,000 miles. I have some other equipment to be considered also. ie; dump truck, tractors, dozers and such. whereas none are run commercialy anymore, the mileage or hours run are minimal now a days, just around the ranch. Thanks for any and all information.
I run amsoil in my gasser, use the 25k oil and change it every 7500, comes out cleaner than any 3k reg oil I've seen. This is run with high temps in the low 100s and below freezing temps.
I switched mine over to Amsoil DEO 5w-40 when it had 1,800 miles. I would have preferred to use the Amsoil 15W-40, but I need a CJ-4 oil because of the diesel particulate filter.
