Synthetic Oil

To the Doctor:

I have a 2005 Chevrolet pickup with a 5.3L V8 engine. I have been running synthetic motor oil in it since about 30,000 miles. It now has 90,000 miles on it, and I have been changing the oil every 5,000 miles. My question is, now that I have 90,000 miles, can I continue to run synthetic motor oil or should I switch to high-mileage motor oil to get maximum protection? Or does the synthetic motor oil have better protective additives?

The Doc Says:

While the properties of high-mileage motor oil (its resistance to burn-off, its ability to help restore plastic and rubber seals, etc.) do make it a good alternative to conventional motor oil, the fact is that high-mileage motor oil is formulated from conventional petroleum base stocks, while synthetic motor oil is formulated from advanced synthetic oil base stocks that are superior in most every way to both conventional motor oil and high-mileage motor oil. If it were my car, I'd stick to the synthetic motor oil, because in the end it will do a better job of protecting your pickup than both conventional or high-mileage motor oil.
