Thank you Thank you Thank you. I did more research on turbos today. Looks like the oil that turbos use = engine oil.

Do turbos shorten the life of the engines? Since the cylinders are getting compressed air, that means the cylinders are getting more stress. That leads to short engine life, right?

Why does Volvo want to use turbos to increase HP? Why doesn't Volvo increase the engine displacement instead? Nissan's 3.5L V6 has a 260-280 HP output (depends on model). Volvo has a 2.9L Turbo with 268HP. (I know I'm comparing apples to oranges, sorry) Both engines have similar MPG and HP output, but Volvo's turbo engine requires more care (synthetic oil). Also, from previous post, looks like the output from turbo engines depends on outsid temperature more than non-turbo engines. Is the use of turbo kindda like an inexpensive way to increase HP....with the trade off of adding more stress to the engine?
