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...

People can argue till they are blue in the face on what brand is actually best. It's like 2 people arguing over which is better, vanilla or chocolate. In the end, both are right. In other words, there is no "best" oil because not everyone will agree.

All you need is to run an oil that is rated for our trucks, whether it's regular or synthetic take your pick. The key is to keep the oil changed on regular intervals. You can choose the Ford recommended intervals, or you can run analysis and let that be your guide.

I used both the Delo 400 and the Delo 400LE and did not noticed a difference in my oil analysis reports (2 of them with the Delo 400LE). Hammer69 turned me on to Schaeffer's series 9000 5W-40 (and there 7000 series 15W-40) and I have been hooked on that since. But I have nothing but positive comments about any of these 3 since the oil analysis reports beat the pants off most other oils.


its Scaheffer's! So where do I get 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.

See, i talked to the closest dealer to me and he said to get 15/40. I guess it'd be fine though. I live in a fairly warm climate, well thsi time of year. its gonna be 90s most of the summer.
