Yeah, I remember that site... I believe
I made reference to him earlier is this
post.. on viscosity.... thanks. I will
check it out.
well i just received an info kit from the fs-2500 company.
sent to me was a copy of an oil report for a motor using the fs2500 filtration system.with 72,465 miles, and using shell rotella t 15w40, i will quote "We would not be surprised to see this oil go 100'000 miles"
this is from Blackstone Laboratories. Maybe i'll scan it in... very interesting results though. Remember, this oil is NOT synthetic!!!
time to revive this thread!
I've recently put 5w50 in my engine, and it starts much better than the 15w40 in there previously. what a difference!!! when the engine is warm it actually seems a bit quieter... it's mobil 1 super syn... it will do for now

and about the fs-2500 filter, i've bought one off ebay and it should be arriving shortly. i'm going to go all out and buy either royal purple or amsoil to put in

the only problem really is where to put the oil return... would it be bad to put the return in the valve cover??? (i would think that the oil might vaporize somewhat... but it would be the easiest). i guess i could weld a 'bung' on the oil pan for an oil line...
I would think on the #1 cylinder side would be best if you are putting it on the valve cover
just picked up my 92 n/a 5spd a/c cruise tilt 460,000 kms. paid $500.00.
it didn't run (no fuel) new check valve and fuel line and it runs idels at 400 rpm and maxed at 3500 no load, adjusted the max fuel screw and now low at 1000 and tops at 5500 no load, under load it stops at 4100.
my bently is on the way, oil and belt this wkend, going with syn 5W50 royal purp, and a can of gm's engine oil supplment (eos)
hmmmm i wouldn't use eos with royal purple... royal purple is already great stuff on its own

i just read up about eos... isn't it just for running in rebuilt or new engines?

get a can of lubro moly diesel purge and run that through the pump... should help clean it out a bit too.
i've never heard of a diesel idling at 400... lol it must have been bucking something fierce!!! :lol:
no eos is used to "beef up" the oil for longer change intervills
ran like a bag of dog crap, using "diesel cleen" product from a john deere guy, this is my first diesel car
So, honestly, what's the recommended OCI on a 92 TD with synthetic? Also, what would it be with regular?
