“I HIGHLY recommend getting an engine with TURBO. You get power when you want it but can drive conservatively to get better gas mileage if so desired.”
You also get shorter oil change intervals, unless you like replacing turbochargers on a regular basis. :)
If you are using standard oil, a turbo can indeed break it down faster - LOTS of heat...
But I have a Saturn Sky Redline, and use synthetic. I get 9,000 to 10,000 miles per oil change. Saturn says you MUST use synthetic with the turbo, but says not to change it until the on-board computer tells you to. (Despite the service manager of the long-closed dealership telling me I should change it at 3,000 anyway. He would if it were his, he said...)
