some cars will experience engine oil leaks when switching from non syntheitcs to synthetics. But the advantages of synthetic are very evident in their ability to withstand high temps, so it is worth a try. If you switch and develop leaks then switch back. The absolute best engine oil is one that gets changed often. You will hear crazy theories about using sythetics and not changing the oil, just the filter etc....BAH. Mobile is very popular and when you look at the testing it is one of the best.
