Which form of fuel does your vehicle use, regular gas, or diesel?

My 2004 Pontiac Grand Am GT uses regular fuel. I used to use higher octane fuel, but the prices these days, I can only afford lower octane.

My mom's 04 Aviator uses normal gas.

I use normal unleaded gasoline.

unleaded on all fronts here. Between the toys and car and truck. I drive a diesel for work though. I've driven other diesels as well and I would own one of my own in a heartbeat if they weren't so expensive.

Unleaded, as money prevents me from buying the expensive Ultra.

Interesting note, it is REALLY not a good idea to put gasoline into any vehicle designed to run on diesel, most newer engines have a sensor which will prevent it from starting but some older models don't and it can result in an epic engine explosion.
