How many miles do you guys get on full tank? (Poor mpg)

[TonyTheTiger57]

The tire pressure on the sidewall of the tire is the max pressure the tire can handle. 42 PSI will give you uneven tread wear, a rougher ride, less grip because less tire is making contact with the ground. This could be dangerous in heavy rain or snow. Increased mpg from higher tire pressures is a result of less friction from contact with the ground.

It is absolutely recommended that you go by the sticker in the door jamb for a stock wheel and tire setup. But if you think you know better than the manufacturer of your vehicle… more power to ya, bud.

My tires wear evenly, I have no issues there.. I get 60,000 miles out of my tires. They don’t wear uneven at 42psi. The manufacturer doesn’t know what brand or size tire I am using so how do they know what pressure to put in my aftermarket tires? I’ll go with the way I have been doing it for the past 25 years.

I get about 330-360 a tank on mine

Take a look at my Fuelly logs in my Signature. You will see many mid to high 20 mpg tanks where I get around the same mileage. I drive mostly city and unless you can time every light perfectly, it’s the constant acceleration from dead stops what kills your mileage.

how you attach that to your sig?

Then keep doing it. All i’m saying is that nowhere on the sidewall does it say you should run 42 PSI. It says a max load and max pressure rating that the tire can safely handle.

Tire pressure is probably the most important thing in regards to mpgs. It’s also the easiest and cheapest.

Mine consistently resets to 395-400 miles range - 2020 Si.

The 2.0 NA isn't as efficient as the 1.5T, but it isn't too far off either. You should be averaging closer to 20-30mpg, even if you're only doing city driving. 18mpg is really low, unless you're just gunning it all the time?

Since you have an older used car, you might benefit from some maintenance. Air filter, spark plugs, oil change, trans oil change, etc.

I drive a 2017 Civic Sedan EXT. Normally I’m around 37 mpg with about a ~350 range in total. I’ll fill up when the trip edges near 300 miles. My car has 90,000 miles, new transmission fluid, new oil, and a new engine air filter.

Oh, and it’s tuned.

Just drove cross country and averaged 42mpg with about ~480 as a range. I didn’t use the ECON button once.

@04sthemi Sign into your account on the Fuelly site. Click on your vehicle you are trying to share. Underneath the log book is a link called "badges". Click here and you will be given the code to paste in your signature.

It's an interesting app to track fill up costs and see what kind of MPG other users are getting. Here is the results for my year Civic.

I have both cars. 2.0na and 1.5t. The 2.0na has always gotten better mileage. And after tuning both cars, that continues to be true.

I been tracking mine on the app since I bought my si almost 2 yrs ago but never used or looked at the app.

Roughly 370 - 400 miles per tank

I am not going hard at all. I had oil, oil filter, transmission fluid, air filter, coolant change so far in last 6 days, and yesterday filled up my gas after resetting my MPGs, trips, and got 225miles range.

I don’t really know why it does gives me around 200+ but not 300+ Miles range. Also I cleaned the mass air flow sensor with cleaner but it was looked clean when I take it off but sprayed it anyways. Nothing has changed idk help?

If you are getting barely over 200. Low 200s, then something is wrong. Even with full blown 3+hr traffic jams. I can make it to 300 miles usually.

Have you tried resetting the trip odometer? Pretty sure that resets the range figure. Reset it and drive it like a grandma for a while and see what number it spits out. I just made a 1600 mile round trip and averaged 39.2 mpg in my Si

I pick up about 350-360 miles per tank on my '18 sport hatch, this is with a Phearable 1.5R tune as well. I don't drive like a grandma but I'm not constantly on the throttle either. My driving is 80% city 20% highway I'd say, my job is 3 minutes from where I live so there's not much commuting to be done. My advice to you would be to get up to the speed of the traffic around you and be easy on the throttle from then on, I like to try and keep the little MPG bar underneath the speedometer over the halfway mark whenever I'm moving like it's a game lmao
