this may sound stupid, but how do you determine the MPG you are getting?

 

Take the amount of miles you drove and divide it by how many gallons you filled your tank up with. Say you drove 500 miles and filled your tank up with 10 gallons you get 50 mpg.

 

Thanks!

 

It also helps to use the same pump at the same gas station when filling up. Some pumps click off near full, some start spilling gas before they shut off. If you use the same pump two or three times in a row you'll get a more accurate number than if you fill up at three different stations.

I usually do try to stick with the same station, or at least the same brand if I can't get to that station (which is on my way home from work, but out of the way on my way to work). I'm thinking I might up to 89 instead of 87 oct. For some reason the engine hesitates when I shift. It did it in my Hyundai Accent too when I had it, so I'm thinking it's the octane. It's just that 87 is considerably cheaper than 89.

Anyone got any ideas or suggestions?

 

I used to use 87 octane all the time, but then I switched to 89 since I got the K&N filter and new exhaust and my gas mileage has stayed the same, if not even gotten a little better. It provides a little more power too. I tried the 93 octane before and it produces more noticeable power, but as you know, the price is outrageous!

 

how does 93 octane produce more power? it burns slower
which is good for advanced timing with mods like Supercharger etc
I'm curious why everyone seems to think it really boost mileage and power (reading other forums too).

The 93 octane doesn't boost a major amount of power, but if I am cruising along at 50 mph and punch the throttle, I'm up to 80 before I know it.
