Yeah, yeah. My engine looks like that. I didn't know it was a turbo, but I knew it had 227 hp. I don't know a lot about cars but I knew this one was bad rump roast, that's why I bought it. Most cars that have turbo say it everywhere, this one says it nowhere so I didn't figure it was the turbo version. My bad. Anything I should do to ensure the life of the vehicle, or any inexpensive tips that I can do to improve the performance? By the way, mine is an automatic, as I have no idea how to drive a stick.

OK, I guess it's premium gas from now on. I haven't heard any knocking yet, but I don't want it to start. Thanks for all the replies.

Yes, I bought it in the US but I thought there were different models. I thought there was a 2.5L that they considered the "turbo" model, and then the next step would be the STi. I'm assuming that if it wasn't a turbo the premium gas wouldn't matter, but if it is a turbo then premium gas is a must?

No, it's just a 2.0L WRX.

Of course it recommends premium gasoline, but does anyone here know if it's really necessary? Gas is way too expensive now and I drive too much to be putting that much money into the tank. I've been switching every other filling between medium grade and premium grade, but I will stop immediately if doing that will cause problems down the road. Can anyone share their thoughts?
