I'm actually going to check the spark plugs today. Come to think of it, the spark plugs havent been replaced for at least 2 years ... the car was a hand me down. I already did a fuel treatment a few weeks ago so I dont wanna do that again, it's bad to overdo those things.
Ya, the gas prices here in Toronto have dropped significantly lately and that's partially due to their switch to the "winter" gas. As for the oil, I just had an oil change and I use synthetic oil only.
