Ok,
I posted a while back about bad hot idle pressure on my ls3 stroker. I recently swapped to a cooler thermostat and reprogrammed the fans to match the new thermo and keep water temps around 175-180. My oil pressure has picked up a good 5 to 8 psi at idle now, and oil temps are setting a bit better around 200 degrees now. Anyway im considering the two rotella oils for use in my car. Either 15w-40 conviental or 5w-40 t6 i live in southern indiana and want to be able to drive the car on the occasinoal cool morning here like 25 degrees on occassion. I change the oil often every 2500-300 miles typically. would either of these oils work well?
