94 oct

[civic91dx]

ok my friend and i where at this gas station by my work place and they sell 94 oct gas. my friend when ahead and filled his tank with it and i told him that he didnt have a use for it since he has a stock 97 civic 4dr lx. i told him the only way that it would benefit him is that if he tweak his timing. m i right. can 94 oct hurt ur car???? well r cars that where not made for it

It's definetely not gonna hurt the car, but you're right, it's not going to improve performance, unless you adjust the timing accordingly.

Even if you adjust the timing, there will be hardley any difference. High octane is needed for a high compression engines, not a stock Honda that runs perfect on 87octane. Too high of an octane will harm O2 sensors - not sure what octane begins to be a problem, but I know for sure 100+ will screw things up.

I used to run 110 octane(race gas) in my bike, that stuff smelled so good too bad it was $4 something a gallon.

The only time you *need* to use any higher octane than 90 is if you've got a VTEC motor. They need at least 92. Any other Honda motor will run fine on 87 (or higher), like jackasssi said.
