me too, and i downgraded to 89

 

3.39 still pumpin 91

 

i have to fill my tank tomorrow
damn my wallet hurts

 

haha, i pump at the shell on bristol and memory lane aka. garden grove dr.

 

why not pump 87? thats what the car is recommended at.

i filled up my tank yesterday at Exxon 3.09 for premium, cheapest i've found around here. but its 10% ethenol blend.

 

87 owns..no need to get fancy

 

haha i pump at euclid and chapmen shell. i know that shell u pump at my homie use to work at the starbucks.

I was told vtec needs 91?

 

vtec..

what vtec

u got a 2x or a 3.slow?

 

jeez, stop using it and get 87.

 

Just flip the vtec off switch and you're good to go

 

nah, our engine was design to us 87, u can use higher grade gas and will noticed that it drive lil smoother....just a lil bit, the rest is all in ur mind. but running higher octang gas in an engine that wasnt design for it would just make things worst.

first, u're paying 20 cents more

second, ur engine is not burning all the gas and even flood a lil making us loose more hp...

and last...from all the gas ur engine didnt burn up would just clogging ur injectors, which are damn expensive.

try it for urself if you get a chance...fill up ur car with 93 and run it on the high way, then fill it up with 87 and run the same highway...u'll noticed that the top speed when using 87 would be higher...u'll feel it at top end....gas milage would be better too.

 

well the only reason why im even that high is that the car run so much smoother with the high octane, but lately i been getting better gas mileage since it burns slower. i might do it the next time i need to fill. but like you just said on the previous post.

 

nope, i think only H22's need it. but i live in city gardens. i hate the pot holes on bristol.

 

^not only H22...but the F20 on the S2000 and the NSX motor too.

 

i almost forgot that

 

ohh alright...so i guess ill start pumping 87? it'll run a lil less smooth but better mileage?

 

i was going to look up all the articles about why its a waste to put higher than 87 in a car designed for 87, but I'll let you do that unless you're just into paying more for nothing. In that case I have some wooonderful Enron stock I've been holding for a really intelligent investor JUST LIKE YOU!

 

in fact, most modern engines designed for even premium can run on 87 without significant problems.

"Today's engines use highly evolved versions of a device called a knock sensor to adjust settings automatically for low-octane gas. And more engine control computers have adequate memory to allow separate sets of instructions for various octanes. The engine control computers keep pushing to maximize performance on whatever grade of fuel is used."

and don't even start in with the I pamper my baby crap. If its good enough for Porsche its good enough for Hondas

"All Porsche engines are designed for premium, too, but it's not available everywhere. "Our cars must be able to drive all over the world, and so we are able to run on regular," says Jakob Neusser, director of powertrain development at Porsche's research and development center in Weissach, Germany. "You don't have to feel that a mechanical problem or anything else will happen" using regular gas, even in the highest-performance, regular-production Porsches."

I read on the clublexus.com that my 98 GS300 with the 2JZ-GE motor was design for premium gas...but once i put in 87 it will detect it and remap itself to optimize with the lower grade gas so that it wont harm the engine, but i will lose like 8 miles per gallon and low in HP. so paying an extra $0.20 for gas and get an extra 8 miles per gallon pay off at the end.

Well the S2000...if i pump lower grade gas...you can feel the car being more sluggish and hear the motor running louder than normal. it doenst sound very health at all.

 

Funny, that's how I feel about putting 87 in my 3.0

 

but on the 2.3

 

i put racing octane in my weed eater. It just doesn't sound right on regular.

 

I didn't know you drove a civic

 

since i bought my car ive always put 93 but man miami gas is getting really expensive i have $3.18 + for premium would it be bad to go back down to 87???

 

i went down to 87, and it seems fine. getting better mileage, but i would go with Shell, don't go to Hess cause i heard that they put water in their gas.
