Synthetic is better, but the cost vs benefit on your car makes it not worth it. ---

Why not split the difference and use synthetic blend? If you do your own oil changes buy whichever, full synthetic or blend, is on sale. ---

I’ve always used conventional oil in my Pontiac and synthetic in my Acura because it calls for 0-20 weight. I see no problem with conventional except recently it is not to be found. Instead there is blended and full. The blended is near the cost of conventional so I suspect I will begin using blended and see if I have a leak problem or not. ---

It uses conventional 5w-30, right? It’s lasted 15 years, right? Why change? Use what you want, but don’t expect it to make a difference as long as you change according to the recommended intervals.
