Default Anyone running 20w50?

Just curious if others run 20w50 oil... this is what my engine builder suggested for my new motor. I hardly ever see anyone mention this oil.


Thanks!

I run valvoline VR1 Racing 20/50. Just personal prefference I guess. Been running it for 5 years with no problems.

Yeah, that's why he told me to run it... just curious if others do or not.

*I see alot of issues with guys burning oil in their rebuild LSX motors... I think its b/c most people run oil that is too thin for their motors? Possible?

Eh, I would say it has more to do with how the clearances in the engine are set. Burning oil in the motor should only happen with larger clearances (for big shots of nitrous) or wearing piston rings. A lot of people are burning oil through their rocker bolt holes as they aren't sealed properly but they attribute it to big clearances or rings.

here in kuwait most of the oil that people use are 20w-50 don`t ask me why but since I knew and can read about motor oils it was 20w-50 ..... german cars run mostly Titan 40 and the others mostly run BP 2000 .... some Nissan cars Run Nissan Gold 20w-50 .... shell and Burgan also is a best seller 20w-50 .... seems to work here in the +50 C in shade in the summer and 6-10 C in winter.
