Do I have to run premium for my b16a2? and why?? any info?

 

I got better gas milage in my HX with 87 than with 92 for city driving. It was on full tanks of gas, buying from the same gas station. Weird.

 

use 89-91 octane when running b16a motors, you'll get most complete burn.....higher octane is not necessary or recommended if the mods are not intensive or knock sensor is running

you can also retard the timing to further run lower octane....

its possible to run B16a with 87 octane without any problems, on a stock ECU and timing

 

car&driver recently had a story on there being NO advantage to a higher octane.
i don't agree.

i assume they don't have oil companies as their sponsers

 

lol, yeas i have run 89 octane and 91 octane on my b16 civic and i can tell a noticeable difference.

 

probably because I'm pretty sure the B-series VTEC motors all have knock sensors. You shouldn't hear any detonation if you use lower octane, but the computer will retard timing and reduce performance. Engines w/ compression of 10.0:1 or higher should use at least 91 octane, otherwise detonation or worse could occur.

 

you're right. car and driver doesn't know anything.
your car will have the highest performance with the lowest octane fuel possible (before detonation.) higher octane=SLOWER BURNING.
regarding the b16a.. use what honda recommends... 91

 

Dude, always go by what the manufacturer/Honda recommends in the manual. On the gas can of 1999-2000 SI/SiRs it say PREMIUM FUEL ONLY. As mentioned with a high compression motor, you should use PREMIUM fuel. If you don't your car will not perform as well. (retard timing, etc.) Also chance of detonation. The way I see it is, treat your car as best you can. We don't have big gas-guzzling V8s with big tanks. We have 11.9 gallon tanks. I use Sunoco Ultra 94 exclusively, and the car runs very well. Don't be cheap...

 

I only give my baby the highest, thats what she deserves.

 

heh we don't even have 91 around here, only 87, 89, and 93.

 

always

 

Would you feed your child discount crap baby food? Dear god i hope not!
