What grade octane should I use?
Hi, I have a 2011 scion xD RS3 and just wondering if I should use regular or premium. I'm only asking this cause I notice the comp. ration on the 2zr-fe is 10.0 which seems pretty high for a engine that uses regular gas. Just want to hear xD owners opinions on this. Oh and can anyone give me some pointers on increasing mpg for my scion, like changing to a trd/k&n filter.
Thanks, Hue |
I use standard. I tried premium but I dont notice enough difference to spend the extra cash.
|
I always used premium since my last car was turbo ii had to but yea i felt with premium on a full take. the box seems more preppy and ready to go lol. but maybe its just me lol. but yea everyone uses different grade and even with regular some people say its not bad..
|
Yeah, because my old gsr with a 10.1 comp ratio requires premium only.

Also since the higher octane is a more controlled burn (resist preignition and detonation), your car is designed for regular, so it may not burn all the gas completely. A guy on Scionlife used high octane before he rebuilt his motor his piston heads were caked. I believe his name was Wesley scion.

They have carbon build up because I'm using Premium fuel, 97 octane is not recommended for the xD, the motor is not designed to handle that high of an octane, the engine simply can't burn the fuel, my motor is proof of that. Oddly enough, I never noticed a power loss, and it never ran poorly." what premium will do to ya: http://i606.photobucket.com/albums/t...torpull017.jpg |
