Re: Twofer: Service Pro oil filters and over-filled oil
Most quick lube places use the cheapest filters they can get their hands on, same goes with the oil they use. A few buddies I knew worked at these joints and the oil drums/filter shipments were all from no-name brands. Your oil cap says 5w-20? Oh well. They would only use 10w-30 because they could get that grade the cheapest in bulk.
A vast majority of quick lube customers don't even check the dipstick, let alone care about the weight of oil. I'm sure they filled you up with 5 quarts, so you are over by 1/2 a quart. Among other things, they'll torque the shit out of the drain bolt/filter, and do a good number on your splash shield.
If you absolutely can't do the process yourself, then I'd personally buy my filters online and grab quality oil on sales at local auto stores/Wal-Mart all the time. For example...
Mazda OEM filter ~ $5.50
Motorcraft semi-synthetic 5w-20 (factory fill in our cars) ~ $12 for a 5 quart Jug at Wal-Mart. Quaker State/Pennzoil can be had for similar pricing.
If you DIY you can pocket the money saved. If not, take it to a dealer and bring them the oil and filter. Both of my local Mazda dealers don't use factory fill oil, in fact they couldn't even tell me what they use, since it changes all the time according to what they can get the cheapest. Not too much different than the quick lubes in that respect. At least if you bring in your own product, you'll have piece of mind knowing what is going in your ride, rather than scouring the internet for information on a generic oil filter.
