andrew_j Posted September 28, 2005 Share Posted September 28, 2005 If our LGT is 50% or more full of super (93 octane in my parts) is it sound logic/fuel mixing to be a New Englander (ie cheap) and put midgrade(89 octane) in to average out to 91 octane? We notice no difference in cars performance/mileage with this practice that saves us ~$1.00 at the pump. My question is mixing a linear relationship?

rc0032 Posted September 28, 2005 Share Posted September 28, 2005 My question is, is it worth saving a $1?NO Link to comment Share on other sites More sharing options...
rallispec Posted September 28, 2005 Share Posted September 28, 2005 From what i've been told by people in the gas station business, the 'medium' grade pump gas is just a blend anyways - so yes, it should be fine to mix to achieve that 91 octane. I would make sure to do half and half at each fillup, rather than filling up half with midgrade now, waiting for it drop half way, and the putting premium.. and alternating the cycle. But it sounds like you're not doing that anyways, so i wouldnt worry about it. like Rclark said though, i dont think its worth it. Link to comment Share on other sites More sharing options...
D-2.5-GT Posted September 28, 2005 Share Posted September 28, 2005 Maybe it was just me, or my butt dyno, but the few times i did use 91 i could tell a difference. Its not worth it, most places only have 91 or 93, not usually both, i just keep going till i find what i am looking for. Link to comment Share on other sites More sharing options...
Guest *Jedimaster* Posted September 28, 2005 Share Posted September 28, 2005 You paid like 27K for your car- pony up for decent gas. Link to comment Share on other sites More sharing options...
Boostjunkie Posted September 28, 2005 Share Posted September 28, 2005 Let me put it this way. If I could get 93 octane (stuck with crappy CA 91), I would gladly pay the extra $1 a tank for it. Link to comment Share on other sites More sharing options...

Cynder Posted September 29, 2005 Share Posted September 29, 2005 Alaska only has, at best, 91. Sometimes only 90! (gulp) Link to comment Share on other sites More sharing options...
