1992 Civic VX: Does it use premium fuel?

[GasSavers_TomO]

What I've found with my VX that has the biggest impact on FE is: Oxygenated vs. Non-Oxygenated fuel.

The non-Oxy fuel actually works better and gives a 1-2mpg boost for my VX as opposed to using the Oxygenated fuel. Biggest issue though is that non-Oxy fuel in my region can be as much as 50? more per gallon than the 87 oxygenated fuel.

Hi TomO,
What is oxygenated fuel?

hmmm. so it seems that 87 octane fuel would be okay in a civic vx. Thanks to everyone for the info...

I mentioned this in my first post on this thread, albeit in slightly less poetic language.

As far as the definition of octane, thanks for the info.

I'm sorry Fetch, I didn't 'got' that. Now I reread your post:
to let fuel "dribble" in and ignite near the spark plug. Otherwise, the mixture would be too hard to ignite...and I understand it. With 'fuel dribble in' you mean rich mixture near the spark plug.
