If you're looking to get good gas milage you are usually looking to save money on gas. Any better milage you get from high-octane gas is lost in the price you pay for it. On top of that, if your car is not designed for high-octane gas, it will only harm your engine and cause it to overheat in the summer time.DrAsperigus said:Good gas mileage =
high octane fuel
synthetic oil
low RPM shifting
slow acceleration
no passengers
manual transmission
That is asuming the price of gas does not change. Around here it as been going up.dficken said:I just caluclated out 15000 miles with a 25mpg vehicle vs. 30mpg vehicle. It comes out to $150/yr if you put 15k a year on your car.

the difference between my P5 and my 1990 Grand Marquis which is comparable to many full sized SUVs on the road...
25,000mi / 11mpg X $1.79 = $4068
25,000mi / 31mpg X $1.79 = $1444
a difference of $2624!
So in my mind, yes, gas milage is very important.
(note: 31mpg is what I average for my driving)
chuyler1 said:tonkabui has a very good point. Any mpg rating is with the car moving. If you drive in stop-and-go traffic on a regular basis it doesn't matter what kind of car/truck you drive, your milage will be worse cause you're not moving.

"The test used to determine the city fuel economy estimate simulates an 11-mile, stop-and-go trip with an average speed of 20 miles per hour (mph). The trip takes 31 minutes and has 23 stops. About 18 percent of the time is spent idling, as in waiting at traffic lights or in rush hour traffic. The maximum speed is 56 mph. The engine is initially started after being parked overnight. Vehicles are tested at 68 F to 86 F ambient temperature."
"The test to determine the highway fuel economy estimate represents a mixture of "non-city" driving. Segments corresponding to different kinds of rural roads and interstate highways are included. The test simulates a 10-mile trip and averages 48 mph. The maximum speed is 60 mph. The test is run with the engine warmed up and has little idling time and no stops (except at the end of the test). "
