Not car .....Truck, I have a 96 Chevy 3500HD 6.5TD Tow Truck (Dynamic, Self loader) and I have a mech fuel pressure idiot light hooked up so when my lift pump goes out I don't kill my injection pump from having to suck fuel from the tank....(the LP delivers fuel to the IP)

I should also mention that before this 10W-40 issue there was synthetic in there....you think this had anything to do with this oil pressure light......
This light was never a problem before, now it's a game to see how long it takes to shut off......Is oil pump R and R a big deal?
Thanks again for all the quick responses

Louis

i think you're worrying more tha you have to. just change back to 5w30 and i think you'll be fine.

i've never seen an oil pump go out on one of these engines in several years of working on them....so i have no idea whether or not it's a big deal to change one.

Thanks for the good words 19......but this rig is ticking even when warm and she used to be like butter/smooth.....I'll switch the oil and hope to be telling you that, "you were right".
haha i knew exactly what you were talking about when you said fuel pressure light, i have a diesel that has the same thing. stupid LP's.... of course i now have an airdog LP in there so it's a non issue anymore.

If you want run a thicker oil 5W-40 diesel synthetic such as Delvac 1 or Rotella Synthetic works - it'll flow like 5W-30 when it's cold but act like a 10W-40 when it warms up.
I'm running Pennzoil Platinum in a 228K LS, doesn't leak it at all. And it improves MPG by a wee bit.

The diesel rated oils have higher levels of zinc and phosphorus - while the newer API SM/ILSAC GF-4 oils have less ZDDP to protect the catalytic converter.
Our engines can handle the higher ZDDP levels - and I've noticed the RH front/LH rear cam lobes look more worn than the ends where the oil feed pipe is. I'm thinking about running Shell Rotella synthetic 5W-40 next OCI. I'm currently using Pennzoil Platinum 5W-30.
