What weight engine oil are you boosted guys running. This is a daily driver....

Turbo guys post up what oil are you rnning? well after my engine warms up my oil looks like water. it gets so thin i think its 10-30 what i have... motor has 950 miles 370ci. 8.8compression, PT88mm turbo. running stock oil pump

oil pressure cold start 43-45psi idle
warm oil after a few minutes engine running from a cold start, 38-40 psi idle
engine hot after a cople of pulls, oil press. around 30-32psi at idle with oil so thin like water - engine hot so hot as hell oil.

will this one work good 15w40 rotella oil or 20W50 oil.......

Thanks

 

Depends on what your clearances were set up for. I was running M1 15-50 per Rex's instructions. Thicker oil for looser engines.

 

15/40 Rotella

 

15/50 in my turbo'd 347... built loose as well. been running Mobil 1, but I'm gonna go to Valvoline VR-1 this time around.

 

0-30 or 5-30

 

just put the new 408 in, running 10-30 rotella for about 500 miles or so, built my motor loose also, and i was told to run 5-30 siy. M1. after the 500 miles is over

 

5-30 m1

 

15w40 or 0w40 in my turbo'd stock 5.3

 

5w30 Penz Plat.

 

The turbo doesnt give a crap, it's the bearing clearance that cares..... I run 5-30 in mine due to the near stock bearing clearance... they seam to be happy.....
