Thank you :) |

I own or have owned 7 and have never used anything but regular gas in them.

87 ran terrible, car surged & shifted weird 89 ran better but got terrible mpg's, like 19=20 91 was fine, 24.5 mpg run good waiting to try 110 from race car just for fun !!! let me know how you do |

Re: octane in my svx
My SVXi don't even like the "required" 91 octane, they run better and get much better mileage on 93 and still good when I have to use 92. Almost all local stations here have 93 octane for premium.

I used to use 97 in mine. Sometimes I would use 95 if I couldnt get 97.

I read an article about it, if you look at the gas pumps they should say octane R/M method I believe they only use R method. The higher number they get is still about equal to the gas we get. This is not an actual comparison but I would say there 97 is about equal to our 93-94 rating. |

I have to use premium to make mine run well..I had to put a half tank of Plus in once..It didn't run smoothly .

Re: octane in my svx
I used to use 87 or 89 it ran fine I lived in ND where there was only 87, 89, and 91 available and the price difference was way too much for premium, now I live in jax fl and 93 is availabe and only about 20 cents difference I notice better power and way better fuel economy using 93. I dont have numbers though.

Re: octane in my svx
The SVX only uses high octane to prevent detonation because of its compression ratio. I would think that with the age (and mileage) most of the fleet is at that lower octane fuel could be used without the engine having to pull timing (and subsequent loss of power and efficiency).

Re: octane in my svx
Most engines probably have suffered from a slight compression loss, like stated above. Also, the air density matters as well. High elevations will take less air into the cylinder making the car run rich. So high elevation cars should run fine on slightly lower octanes as well.

Re: octane in my svx
Maybe we should run regular and add Toluene or Xylene. It would keep the fuel system clean and boost the octane.

Re: octane in my svx
I wouldnt do that without buying some seals and dumping them into a bucket with those chemicals. Probably not a good idea. I heard of someone using acetone to get better fuel economy. But that's the kind of thing you do with a rental vehicle.
