does anyone know how many MPG does 100 octane give on a standard B18C5 on reglar every day driving?

 

There are so many different variables that would dictate your MPG. It is nearly impossible to estimate haha.

 

Octane = detonation resistance. It will not improve your gas mileage.

 

10.6

 

Not as much.

 

damn I wish I had your money.

gas is 2.83 here on regular unleaded.

Is there something special about the motor that you have to run 100? If not 92 will be just fine. As said above, the higher the octane the better "detonation resistance" not the higher the MPG.

When the news hits that the Saudis are looking for more places to drill but their current rig's production is falling, then the price will spike, lol.

3.17-3.30 on regular here in socal.

 

3.05 here for regular on Long Island

why waste your money on 100 octane?

you runing 15.1:50million CR with turbo nitrous and supercharger

or are youstock and think 100 octane will give you 500 more horse power?

 

higher octane does increas gas mileage. i get better mileage with 92 then i do 87. and no its not all in my head. its true.

at least with shell.. less ethonol that **** burns too quick.

 

gas is 3.39 here at chevron suxxx

No it's probbly due to what ever you are using in your motor makes it run 92 better.

Remember all gas has 4 oct varriance around.

Why are you pouring 100 into a stock ITR motor anyway?

 

ummm stock d15b2 with mpfi swap? i dont think so.. lower ethenol in the gas is what makes it better.

 

2.98 for premium... i got it made! lol

 

its 3.99 for 110... not to bad i guess.... i was gonna use it, but i said the hell with it... im not a balla

Yea it would still be at a very low comp ratio, you could get away with 85 oct.

even 93 in most places is 10%. I'm curently helping run a car that'll be on 85% octane and it'll make my z28 look like a girl scout, it's not ethenol making gas bad....

Same here.

 

cant get 85 in canada.. at least its very hard to find.
i only run 91 when im going on long trips . always run 87 otherwise. but i do get better mileage with 91.

lol, good luck finding it anywhere, just I read that in my owners book.

It can't be the gas, it's something else or you arn't recording milage correctly.

If anything that gas would be worse for you.

Are you aware that your engine isnt completely burning all the higher octane fuel?
Is the placebo increase in fuel economy worth the increase in price per gallon, or the higher emissions your car now emits?

Are you making the exact same trip driving the same way?

Read up on recording milage, its not just drive till shes on E = milage.

85 I don't know where to get, what model is your car if yours is a dx or std *cx* it should say it'll run on 85 least mine does.

Even the si didn't need 91.

 

what ever.. all i care about is how many km's i get on a tank of gas.. thats all that matters.. but you can get a ruff estimate using the size of your tank plus the amount of km's you drive. i get about 40miles to the gallon.

4 door dx. manuall really says 91 or higher.. its weird i know. maybe its cuz its canadian

And when the change will only be a 1-3 mpg off you won't see it using such a rough estimate.

I'm kinda shocked to hear the books up there say 91.

Not one time did any of my D motors see 91, 89 at best.
