does anyone know if i can fill and engine that is suggested to run on regular clean gasoline with premium 94 gas?

jdmb16si

yeah

92civeg

yes

92b16vx

Why not? Of course you can.

JDMlyfestyle

Yes ur car will love it too. burns cleaner and ive noticed i get about anoter 45miles out of 96 over regular 89.

jdmb16si

hell throw some octane booster in with it too go all out

chads

ya you can but it is pointless unless your engine calls for it, you wont get any hp or anything, but it will help if your car is pinging.

The Internet Tough Guy

^ yep. always use the lowest octane you can get away with, without pinging.

tominos

use to always fill with premium but am really poor now and regular does the same thing.

CivHizzle

no, but deisiel works great

to being too poor to pay the extra $1.50 on fillup

and diesel work great!!!

right on the money

High octane does burn cleaner but it also burns too hot for some engines and over time it will affect performance of the motor.... non turbo and stock compression hondas are good with 89

B/cuz they aren't engineers.... ****, I don't know.... 87 sucks, and I dont care what anyone says... It does make a difference....

what kind of pinging are you talking about? THe kind when you turn off the car, and it makes a pinging noise? Or something else?

detonation. the higher the octane the more resistance it has for detontation.

SolObsession

It may be in my head but my Sol runs best on 93. And the low grade gas is just old high grade.

But I am.

And you shouldn't use more than is needed. Too high octane in a low compression motor leaves gas unburnt, and harms 02 sensors and catalytic converter over time.

(Says my Mech. Engineering degree from UCSD. Yeah, I know. I don't have a life.)

If you think running 93 octane in a ... 8.X:X or 9.X:X CR motor actually IMPROVES performance, emissions, or anything like that, it's your imagination- Unless there are other problems with your motor which were causing it to ping with the recommended 87 octane in the first place.
But show me some documentation to substantiate those claims and, upon reviewing and agreeing with it myself, hell, I'll take it to some professors I know from school and have them review it- Because such claims, if by some profound method were found to be true, would be a revelation for the automotive engineering curriculum!

This man knows what he is talking about!!!

Yes you can and should do so without fear of problems. Its ok to run 87(so they say) however higher grades (in my "opinion") shoud be used more regularly. Deposits left behind (by lower grade/87 oct.)can create problems causing the fuel to be twice burnt in the chamber. The deposits left behind can super heat and ignite fuel before the plugs have a chance to fire. Its ok to run 87 but its better to run mid grade or higher, also most will find better fuel econ. Im sure their will be those who'll argue this but I found out the hard way an blew a head gasket. So yes you can run 87 but why would you want to? Dont be cheap, be smart! A little more at the pump will be better than alot more at the shop!? You could always ask a certified TECH, somone who has a little more time inside engines. See what He/She says!

A few people here have said its better to use 87 on a stock Honda, non boosted etc...
what about if you advance the timing? Then shouldnt you use 93?

uhh jya!

mike93eh
