Default Engine Oil: Synthetic or Regular
Now that I have new brake pads, it's time to change the oil. Not sure if I should go with regular oil or synthetic. I've heard good things about synthetic, but I'm not sure if there really is a performance gain that justifies the price. I'm thinking regular oil would be fine, what y'all think?

Check the Tech/Perf forum. There is a long thread debating that right now.

If you change your oil every 3000 miles or once a year, I'm not sure synthetic is worth the expense. If you ride 'em long and hard, then you might choose synthetic.

synthetic is defnitely better for hotter running temps. I would switch to synth.

I would run what the owner's manual recommends...most likely Mobil 1 synthetic. Chances are that is what the previous owner/s ran.

If you are talking about your '91 C4, I'd go with the factory recommendation: synthetic.

You'll probably never really NEED it, but peace of mind is worth something.

Any combustion engine is better off with synthetic oil. It leaves a coating of lube on the cyclyder walls and rings that add protection after not having have run the engine in a while (which might be days or weeks). Gravity pulls conventional oil to the bottom. Slick-50 used to be the way to go for this function.

The first few cycles of an engine starting with dry cylinder walls is a bad thing. Over time, having have experienced the dry cycles will show on the rings and walls.

Go with the devil you know. I thought only the mighty LT1 was shipped with Mobil 1.
