KSTHANE Posted March 26, 2005 Share Posted March 26, 2005 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?

beezer Posted March 26, 2005 Share Posted March 26, 2005 Is it a turbo? Link to comment Share on other sites More sharing options...
KSTHANE Posted March 26, 2005 Author Share Posted March 26, 2005 Is it a turbo? No, it's just a 2.0L WRX. Link to comment Share on other sites More sharing options...
mattocs Posted March 26, 2005 Share Posted March 26, 2005 No, it's just a 2.0L WRX. Did you buy it in the US? If so, then it is a turbo. (Do they even make them in other markets without the turbo?) Link to comment Share on other sites More sharing options...
KSTHANE Posted March 26, 2005 Author Share Posted March 26, 2005 Did you buy it in the US? If so, then it is a turbo. (Do they even make them in other markets without the turbo?) 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? Link to comment Share on other sites More sharing options...
beezer Posted March 26, 2005 Share Posted March 26, 2005 yes on the premium gas. Link to comment Share on other sites More sharing options...

The WRX is turbocharged and the STi is turbocharged...but a bigger engine and bigger turbo. You need premium gas because your engine will knock. Higher octane = higher compression ratio. I don't know if any damnage will be caused...but you're engine will knock and you might have a decrese in performance. Link to comment Share on other sites More sharing options...

I haven't heard any knocking yet, but I don't want it to start. Thanks for all the replies. Link to comment Share on other sites More sharing options...
kevinsUBARU Posted March 26, 2005 Share Posted March 26, 2005 I'm not bustin' your chops or anything, but you had no idea you bought a turbo? Link to comment Share on other sites More sharing options...
mattocs Posted March 27, 2005 Share Posted March 27, 2005 I'm not bustin' your chops or anything, but you had no idea you bought a turbo? That is the selling ponit of the car. If I didn't want a turbo (or even know it had one), i'd spend like $8,000 less and get the RS 2.5. Link to comment Share on other sites More sharing options...
kevinsUBARU Posted March 27, 2005 Share Posted March 27, 2005 Yeah, that is definately the selling point for the car! Did you ever notice that something was different when you pressed the skinny pedal? Seriously...was this a used car dealer or a Subaru dealer? Does your engine bay look like this?

Did you ever notice that something was different when you pressed the skinny pedal? Seriously...was this a used car dealer or a Subaru dealer? Does your engine bay look like this? 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.

beezer Posted March 28, 2005 Share Posted March 28, 2005 I'm guessing you won't be working on your car, so I would suggest just to keep up the recommended service on your car. All this should be in the owners manual, it is probably in your glove box.(might cost a fortune from the dealer, but, probably worth it.) Be careful with the auto transmission, try not to spin the tires too much, and make sure you come to a complete stop before shifting gears. Don't ignore check engine lights or your gauges, get them checked out. Enjoy the car, you will learn more if you read up on this site, there is a lot of good info. Enjoy your new found turbo.

My WRX is also an automatic, if you drive the car hard at all you're going to want to install a transmission cooler on it. And, switch over to synthetic fluids at the first scheduled maintenance. I actually learned how to drive stick on my wife's WRX. Link to comment Share on other sites More sharing options...
