I am a delivery driver, which means a lot of stop and go driving, idling, and a lot of restarting the engine. I know this type of driving is [censored] for GDI engines. Right now I am running Quaker State Synthetic 0W20 from about Nov to April because of the extreme cold in my state (gets down to -25 a couple times a year) and will switch to Quaker State High Milage Blend 5w30 from April to Nov. 5,000 miles will likely not be reached on either oil change. I also run the OEM filter and put some Chevron in the fuel tank every oil change. Is this about the best I can do in a bad situation for a vehicle? I have 96,000 on it and she runs perfectly at the moment.
