200 Miles/Tank
With 20.4 miles on the counter, I filled the tank with 13.3 gallons. Might I mention below half a tank, my fuel needle is right about 40% of the damn. Damn check gauges light always let's me know.
On my drive to work this morning, I drove 57.9 miles highway, no traffic, no lights, and not going above 2,500 rpm.
As of those miles, I expended a 1/4 tank of fuel. Which, if I calculated it correctly is roughly 14 miles a gallon.. Highway. Giving me around 230 miles/tank.
No check engine lights exist, merely the random flashing brake light and abs inop light.
I feel as though my mileage should be quite a bit better than that. Mostly stock '00 SS. Just long tubes, true duals, and underdrive pulley. So either the gas gauge is wrong, or there's an issue with the o2's, possibly something a little more serious, or maybe even the tune the previous owner (stealthss) got on it.
Any ideas before I start spending some money and not get any results?
I'm think
In my defense, 1 tank last me 3 weeks, I have about 1.5 mile commute to work, everything else i need is within 3 miles...so theres a whole lot of sitting at red lights, and stop and go driving.
i recently drove 1300 miles over 4 days, on a vacation trip, 99% interstate, hauling ***...80-90 mph the whole time, got 26 -28
I commute 56.2 miles a day (round trip). To work is 95% highway, but speeds on the one highway are approx 20-30 MPH (traffic) and on the other are approx 55+ depending. On my commute home it's 45% highway and the rest are back roads. It takes approx 40 mins in the morning and 55 mins in the afternoon. I get around 200-250 to the tank during my commuting.
On a recent trip to the Outer Banks and back I was getting around 300-400+ miles per tank (95% highway).
I get a solid 23 mpg based on the right way to measure; fill the tank and reset the trip counter to zero, drive for several hours and refill the tank, note how many gallons were added and use the mileage to do the math.
Of course my engine is still stock. When you start modding the engine you are rarely going to improve power and mileage at the same time. It's one or the other.
Stock versus stock they aren't hugely worse, but they are still worse.
Unfortunately, that still doesn't save me from 12-13 mpg in spirited city driving with the AC on.
All city driving.....sucks.....200 to a full tank if I drive mostly casually, with a few hard runs. If I have a really hard driving (fun) week, 150 miles to a full tank.
