Since it's been discussed in the "Anyone do any Mods yet?" thread, I was curious to see what type of gas you use in your Impreza?
The car is rated for regular unleaded, but if you feel like dumping a couple extra dollars using premium won't hurt. I had a 4th gen impreza with uel header swap and custom cat back that ran smoother and cleaner with the premium gasSince it's been discussed in the "Anyone do any Mods yet?" thread, I was curious to see what type of gas you use in your Impreza?
Unless it calls for something with more octane, I run regular.
That being said, if given the opportunity, I like filling up with the old school, ethanol free stuff. It's more expensive than ethanol blend but I've noticed about 10% gains in fuel economy and my "butt dyno" registers a bit more power.
Ethanol free is all the only gas I run in our dirt bikes, UTV, mowers, trimmers and chainsaws. Not only do they run better but the fuel stays fresh longer, which is important for winter storage.
Not necessarily a different color. The mom and pop gas station where I buy mine just advertises it directly on the pump. One pump is dedicated to non ethanol and the two adjacent pumps are either regular 10% or diesel.Where would one find ethanol free gas? Is the pump a different color like diesel or E85?
Interesting replies. With using say premium gas for instance, you hear about hearing a "knocking" sound. Is anyone worried about this occurring? Just curious. My last car, 4G Eclipse, recommended regular, but since I modded the CAI, headers, exhaust, etc, I ran premium & felt it had way more power & got better mileage.
