Actually the exhaust coming out of most engines is about the same temperature as the exhaust from our turbocharged cars. And a turbo, or the engine for that matter does NOT have to be at the same temperature as the exhaust, that's why it has cooling to keep it from getting too hot. The uncooled parts do get very hot, but the parts the oil lubricates and cools are kept at temperatures the oil can handle.

BTW -I use synthetic and change it every 4000 miles or 5 months on my WRX.
