Calculated out the gas mileage today..... 32.1x mpg.

98 Octane rocks

 

wow

 

 

Whoa whoa whoa, how the heck did you manage that?

Pretty fawkin sweet.

 

that wont last long. im pretty sure running 98 octane on a stock truck engine isnt good. plus by the time you factor in the extra cost it wouldnt really matter if you used 87 and got 25mpg or if you got 32 out of 98 because they prolly equal out.

plus 87 is alot more avalible than 98. id just run the 87.

 

Yes, but I have 3 and a half 55 gallon drums of it, which will go bad by summer. Using it instead of buying gas. Drove very very very grandma like. Its boring.

 

wow. And I'm only getting 18 out of mine.

 

i get around 32 on 87 octane....tear down the top of ur motor and have it bored out and you'll get better milege lol :)

 

hell im getting around 15-16 out of my 4.0. what am i doing wrong. (aside of having my foot burried in the gas pedal).

andrew

 

i get 12-14 regardless what octane im using

 

4.0 won't get that kind of mileage.

I normally get ~27 in mine. Do a full tune up, you will be surprised.

 

How much do new catalytic converters and evaporative canisters cost?

 

Unleaded fuel.

 

sounds like my truck and it prob dosent help that i shift like a moron either

 

whats the specs on your truck??

 

whos truck?

 

The guy who started this thread...I wish i could get 15mpg...let alone 30

 

 

Being in how this is the 4 cylinder forum, I have a V8.

 

29 highway, 24 city

 

It doesnt matter how I drive, I average 14.5. I can drive with my foot to the floor, or drive like a grandma, it never changes. Premium fuel doesn't change it at all either.

 

2003 Silver FX4 Level II 4.0L

You have a 4 liter, I have a 2.3.

 

I know you are getting that fuel for free, but
you are absolutely doing damage to your engine and emissions systems running 98 octane fuel in regular use

 

wish mine was a stick... would actually like the mpg i was getting.. :P im getting 13 right now (without recal. my odo..) which i'm guessing is really about 15.. i might be wrong though..

 

oops.. srry didn't mean to jack this thread.. didnt notice it was 4 cylinder :P
