dont use anything but synthetic oil... doesnt really matter how new or old your car is, run synthetic. its worth the extra money.
I don't agree. It's not worth the extra money IMO, especially if you're going to be extra anal and diligent about changing your oil often, like every 2-3K miles.
Keep in mind this is coming from someone who ran Red Line, Royal Purple, or Syntec in all of his cars for a couple years before he wised up and realized it wasn't worth it. If you're a competitive drag racer, and you're looking for every last advantage for power, and you don't care if you're spending $300/yr on motor oil, great. Go for it. That's not me though. My car makes well over 300 whp on old fashioned dinosaur oil, and that's just fine. If I want more power, I'll turn up the boost a pound or two.
If you think synthetic oil has some sort of magical power to keep you from spinning a bearing if you drive around 3 quarts low, or it will somehow protect you from melting a piston from detonation, you're sadly mistaken.
Also, if you have an older car with a lot of miles on it, you might be surprised at the new oil leaks your car will develop with synthetic oil.
