I THINK this would be the right forum, if not feel free to move it.

ok, I have a 2000 7.3. Ive read on here that there is one brand that is top notch, lasts as much as 20K if you use the FASS system and do the scheduled tests. i wont be doing that so Ill go maybe 8K and change it. I have synthetic in it now (something from citgo) but want to run the best I can get. Im conservative so even w hen I ran conventional, I only went 3K. I cant for the life of me find that oil now that i want to find it. If I cant find it soon Ill just get some Amsoil from the local diesel hi-po shop but if its not a huge difference in cost I was thinking of getting this other stuff. it was an odd name thoguh. anyone know wh at it'd be? Im sure tons of you use it, just figuring out what Ive seen so many times here now that i want it...

If you run schaeffers at 8k intervals, I'd love to have the money you're throwing away. Your over conservative use of regular oil at 3k intervals is hugely wasteful. Do an OA once in awhile - you'll find you can go out to 8k with regular oil just fine in most driving, and if you decide to go with Schaeffer's, and use bypass filtration, you should be able to see 20k easily.

Use science instead of old truckers tales and you'll save money and a precious resource.

Schaeffer's 9000 5W 40.
