1999 Acura Integra mileage: 74,500. You may think this question is silly but I've learned there isn't such a thing. I'm wondering what's the best oil (and weight) to use. I average 80 mph on the highways (to and from work). It can get very hot here in Georgia in the summers and I want my engine to have the best protection. Your suggestion/advice will be greatly appreciated.
Your owner's manual will give you the answer you seek. The oil weight varies from vehicle to vehicle and from operating temperature range. In other words, if you live in Alaska, your oil weight will differ from someone who lives in Georgia. Any of the major oil companies have good quality oil.
