It says that it is based upon engine revolutions, engine temperature, and miles driven. I also know that time is critical, owners’ manual says a maximum of one year.
What would be the longest oil change interval for a car being driven less than 1,000 miles per month? Would the season matter like changing more often in Summer than Winter?
In the past I have been driving more miles and generally change the oil and filter every 6,000 miles based upon the New York taxi cab study presented in Consumer Reports several years ago. But alas, I do not have any experience with dexos oil, which if I understand correctly is synthetic.
