Castrol, Shell, Chevron,
Texaco...I do check the API (American Petroleum Institute) rating to be sure it is as high as possible, and it always is. I change it once every 5 to
6 months, or ~4,000 miles (3 month or 3,000 mile oil changes are a myth sponsored by Jiffy-lube et al. With modern detergent oils it is a waste of
time, money, and resources link ).
