I've noticed my mileage has gone down a bit in the past month or so. I recently checked my oil and it was a bit runny and smells of gas. It has been frigid cold here lately and I do take a lot of short trips in town with my subie, So it usually gets around 19mpg which is normal for me. Not sure if I should be concerned about the thinner oil and gas smell though. Any Ideas? Thanks!

Are you letting your vehicle idle for long periods due to cold? At any rate I would change the oil as soon as you can.

Fuel can slip past the piston rings and get into the crankcase, only taking short trips exacerbates the problem. Change the oil. Are you getting piston slap or chattering on startup?
