Ten bucks for an oil change, tire rotation, and a 22 point inspection where they find 300 problems with your car that need to be fixed by them ASAP! ;-)
It's amazing that changing the oil filter on my 17 year old mini van would "greatly increase my gas mileage"! Hah! Putting gas in the tank barely increases my gas mileage. But hey, for ten bucks you can't go wrong if you can put up with their pestering.
There is a $3 disposal fee where permitted, whatever that means.
