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.

VA4meds is a auth dist on this site.

 

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.

 

I also run the Amsoil ineverything I own, Always have. I am also an authorized dealer as well. If your interested, pm me for a quote.

 

amsoil here as well. . .got a preferred customer acount.

 

Hows does Mbile One perform? I run M1 in my Hog, but thats an even heavier weight oil (20W50) than for diesels!

 

Amsoil all the way.

 

Amsoil in engine, transmission, front and rear diff & transfer.

 

good point on the tranny and transfer case, i need to check when im supposed to change the xfr case, and tranny is needed, at 30k already.
