I personally wouldn't use it. I don't use anything thinner than an Xw-30.
The difference is: the 5w-20 is thinner than 5w-30. |

do you lose oil in between changes? if so you can even step it up to 10-40.... i run the 10-40 RP in the winter time and a 20/50 blend in the summer.

![]() Since RP 30 weights tend to shear to a 20 weight rather quickly, I would use 10W40 year 'round if you want the best protection. If you favor a minor increase in gas mileage over better protection, go with the 5W20. -Dennis Last edited by bluesubie; 01-30-2007 at 08:53 AM. |

this is line with the way my car responds to RP. BUT, everyone's car is different. that's why i suggested blackstone labs, between having your oil analyzed and watching for consumption issues, you can find the "right" viscosity, which varies from not only region/area, but car to car also. |
