13.7MPG, and still at it!

Or even better reset your odo when you get a fresh tank of gas and next time you fill up take whatever your odo recorded and divide it by the gallons you put in verified via the pump.

That is what I do, but since there are like 10 of these threads in the last 2 days, I am wondering if it isn't a math issue.

[NAiL05]

Word I always do mine that way. This is the first time I have seen a fuel thread in a while.

[JDMxDB8]

Damn that's some shitty mpg.

Explain to me how you calculate your mileage. Something else is up here, because if you were burning that much gas, there would be obvious signs of it. That is over 2X the fuel consumption of a regular healthy F22.

KM to miles with online converter - 375
Fuel from L to Gallons with online converter
375/X (X=G) = MPG.

I was at work today, and one of my coworkers told me to pull my plugs, he wanted to see them.. Sure enough, FRIED - The electrode and the ceramic portion are covered in a tainted purple residue... From SEAFOAM. I used to put half a can every 5 fills, and half a can into my oil 5-10 mins before an oil change to clean up the shit in the oilpan when i drop it. Now it looks like i need new plugs, and a VC gasket. The plugs had oil residue on them (the top and the threads)

Fun times.
Also, one other thing that needs to be clarified, we use 87Octane gas, with 10% ethanol thats already int he gas, there is nothing we can do about that. With my WAI, and exhaust header, should i be using Iridium plugs?

[starchland]

jesus man thats alot of seafoam christ now you need something to get rid of all that seafoam

[Otto]

We have 10% mandated ethanol here too. I've never gone below 27mpg (over a tank, 87 octane) in New England. High is 34 MPG.

generally a restricted exhaust will kill accelleration, especially in higher RPMs. Though I'm sure other have better info than me on that.

[NAiL05]

lol seafoam every 5 fills is a little too much.

That would do it too.

And for you equation above, were you dividing miles or KM by liters added, or the liter capacity of the tank?

Dividing Miles i drove by the gallon equal that i filled up in. Since half a can every 5 fills is too much, it looks like im going to need to do more. Im going to need to pull out the Marvelous Mystery Oil and put it through the combustion chambers, whatever is in there, must come out, all that extra seafoam is now draging out my car basically. Next time i go to fill up, im going to use Medium Grade - 89 Octane instead of 87

waste of $.

[starchland]

i would get that fucker as hot as you can and run an engine flush before you change the oil.

Oy, as hot as i can? Like in 2nd gear doing 60 MPH kinda hot? lol

[starchland]

i dunno lol it sounds like you have some gummed up residue in there if your combustion chamber is purple like you said your plugs were i would hate to see your head...just drive her hard and maybe it will burn off. Im also thinking maybe all that seafoam fucked up your cat as well

[js593]

Fun times. The seafoaming only started about 2 months ago, when i was having real problems. My car would stall out for no reason, and the seafoam cleared it up, now i need new plugs, cat, vc gasket... etc... im not thrilled. Im ordereing one off NOPIONLINE tomorrow, a high flow direct bolt up cat converter. 89 bucks shipped, cheaper then i can get a stock one at. so im happy.

Thanks guys, gonnaa replace all that shit, and see what happens. I'll bring it up to WOT a couple times, and bring it to the track for a few runs and hope for the best.

Thanks.

[starchland]

yeah thats a good price for a bolt on and check rockauto they might have some good prices for you. let a few more guys chime in they might have some more ideas but it could also only be your plugs that are the problem so try that first its cheapest
