tune up for long trip

[Scottydoggs]

you need to fill your tank, set the trip, run the gas down to where you would fill up, then fill the tank again, take the # of gallons you just put in and divide the miles driven, = mpg

did you calculate your mileage?

miles per tank doesnt mean much if you still have a quarter of a tank left when you fill up.

Lmao, I like this. But yea, my hunch is that he did the math wrong.....

i used my gps to track distance and divided the miles by the amount of fuel it took to top it off, it came out within 2 mpgs of my trip computer thing, this might be because i am running 235/55/17 tires instead of the 225/55/17 stock (i think thats right)

You should have a code for that.

you wont get a code until the cat overheats. with 110k on a stock dp you probably have a cat thats getting pretty clogged. id get it replaced before you get any bad issues.

if you were doing 60-70mph the whole trip i bet youd see some better gas mileage, but 22 highway is kinda low.
