SoCal gas quality: any actual info
Hey,
I recently flashed my car to the ACN 91 stage 1 tune with BM3, and I wanted to know if anyone has access to any actual dating showing AKI/Octane differences between gas stations. I know a lot of people swear by 76, but I am interested to see if there is any actual data to reflect that or any other higher or lower quality gas. |

So far so good but then again I'm not tuned. I would think the best course for you would be to try Shell, 76, or Costco and log the car to see the differences. |

One answer to the problem is to throw a few gallons of VP racing (or similar) 100 octane fuel into each tank and Hang On!. It gets expensive though.

Sadly I have no data, but I've been using Chevron, Shell, and 76 in that order for my performance cars ever since my mother got her first 1999 corvette.
If you want to be super safe, do like AlpsRider recommended. Do a bit of math to determine the amount of 91 and 100 octane you need to hit 93. I have a 76 near me in Pasadena that sells 100 octane for 9.99 a gallon. I squirt in two gallons before track days in my WRX to ensure quality fuel is in the tank. Alternatively, I believe you can still buy a barrel of proper octane booster online and have it shipped. It isn't terribly cheaper though. |

I bought some octane booster but then after reading about it possibly fouling plugs I chickened out on using it. It would be nice to know if it's safe.

I am planning on swapping my plugs soon, and I am running Boostane premium mixed to roughly 93 octane in my car. I'm going to try and do that for about 5,000 miles and analyze what I see on the plugs.

The reason I started using it was that I was seeing timing being pulled without it on the BM3 Stage 1 ACN 91 tune, although that was also on the stock intercooler. Maybe the CSF intercooler has done enough to IATs to prevent that. |

I've got a local gas station that sells E85, I am going to see how that compares. |
