What weight oil for my 88 7.3 IDI w/ Banks turbo?

 

I run Shell Rotella 15w40 in both my trucks.

 

Wally world had 2.5 gallon jugs on sale for $20 right now; wish I could stock up! 5W40 would be for something like a Jetta, wouldn't it?

 

Yes as a matter of fact i work at wally world in automotive. I actually took my last pay check and stocked up on the 2.5 gallon jugs on sale @ $22.50 bc they are cheaper than 2 gallons regular price @ $11.50ea your getting a half gallon free . And yes the lighter weight is more for like a Jetta or other small TDI engines

 

WTF does TDI stand for?

And how is spending a whole Wally world paycheck on $22.50 jugs "stocking up"? Two jugs isn't stocked up! (LOL, I get to talk smack now because I finally found a few days' work!)

 

TDI means Turbo Direct Injection. No i didnt buy just 2 jugs thats only enough to do one of my trucks. Between my 2 trucks and the farm equipment it dont take long to burn a whole paycheck on oil . So i grab it when its cheap/ cheaper

 

I was just joshing you about that; not meaning offense.

 

No problem no offense taken

 

i like running mystik 15/40 works good in my truck and works real good in my buddy D6R

 

We got a few cases of that mystik 15-40 at work a few weeks ago. I've never heard of the stuff. How long have you been using it?
