Another gas mileage thread
After some searching it appears people are getting a wide range of average mileage to the gallon on their svx's. I've read some getting 15 mi/gallon to 31 mi/gallon. I was trying to gauge where my svx was compared to others.
I recently drove 465 miles (mostly highway) and could have gotten more if i hadn't feared stalling out on the highway. I am using the highest octane available at gas stations (91/93). Anyone else in this range? |

Re: Another gas mileage thread
I had to drive ALOT this past week with my son Nick coming home for a short visit.
Two trips to Pittsburgh PA, a round trip to see my son Dave in Norfolk VA. On one trip at mostly 72-75 MPH, in a 4.44 Pearlis, 336 miles shown, but 318 actual miles, (4.44s have a built in 5.5% error unless you put on taller tires) 11.9 gallons of corn fouled premium, 26.76 MPG The trip back trip back got us 25.something something. The last trip includes some city driving as well; 303 miles shown, 287 actual miles, 13 gallons premium, 22.09 MPG. Stock exhaust, and LANs TCU and ECU stage 1 agressive chip. 236,000 miles on the car.

Re: Another gas mileage thread
Forgot to mention I have BBS rims so my tires are slightly bigger.

Re: Another gas mileage thread
225/45/r17 Not sure if it makes a difference just throwing it out there. I should see a slight increase in MPG now that my A/C idle pulley bearings decided they no longer want to be confined. they wanted to explore the engine bay.

Re: Another gas mileage thread
Your new tires are 3.3% taller, roughly. So, your actual milage should be 3.3% greater than you think.

Re: Another gas mileage thread
High teens/high twenties for me, as always. At somewhere between 1/4 to 3/4 tank I top-off alternately with 87 octane regular or 93 octane premium. Stock everything. Non-pampered daily drivers.
Occasionally the mileage I record for a given distance comes within a few tenths of identical to a previous run. With such consistency I figure I'd know pretty quick if some subtle something were to go wrong with the car. dcb |

Re: Another gas mileage thread
I'm in a very flat state and I'd say I do 50/50 highway:street driving. I'm getting 17-18mpg, and I'm babying it. But I have some weird issue(s) I'm trying to clear up and hope that it fixes my mileage too.
