o2 sensors are under warranty so i decided to try running 110. pretty much stock motor as of right now. anyone know how much timing i can run safely?

Just do like normal and advance your timing like you normally would. Go until it doesn't sound right and back off a bit.

you dont have the mods to warrant it... just wasting money

It won't help, it will hurt.

Octane(without getting into EXACTLY what it is) is basically a measurement of the fuel's resistance to ignition sources. Higher octane fuel generally is harder to ignite and burns more slowly, but as a result is also less prone to detonating. Running high octane race fuel in a low compression engine will probably just hurt power, or at the very least will result in slightly worse mileage and possibly plug fouling.

Most premium pump gas is a bit better refined and has less crap in it and a better additive package, so you can justify running 91-93 on a street car, but not 100+ race fuels(unless it's a high boost blower engine).

AV and youll be able to advance it an easy 100* dude!

I'm going to be a 4th and say that its a complete waste of money. Numerous reasons s already explained above.
