Hi i just bought a Chevy Uplander 2007, owners manual indicates you can use it with 87 octanes gas (regular), is there any benefit on using a 92 octane gasoline beside the power?

There is no power benefit to using 92 octane ... follow the recommended grade of fuel in your manual.

Golfer is correct. Higher octane fuel than what your engine is designed to use can actually made it run rougher. The higher octane fuel retards the timing. Premium can be used, but I would not recommend it.

All it is it to reduce engine knock on high compression engines. The higher the octane the more hydrocarbons are present.
