whats the difference between the filter under my head and the one in my glove box. i just went to jiffy scam and they told me i needed BOTH repalced. i know how to replace the one under the hood myself, but then then showed me this other one that was more flat and they said it had to be accessed through the glove box? who knows. it was $30, and i replaced it.
i have a 2005 toyoto matrix.
was i scammed? there were leaves in it. how often does this need to be changed?
what is the difference between that air filter and the one that is under the hood. thanks.
also, totally unrelated. synthetic oil. what's the deal! my step dad said i could go 15,000 miles in between changes. i have gone 7,500 and i changed it. the same dude at jiffy scam said that i was insane and no one can go that long in between oil changes. who is right? is it bad to go 15,000 in between changes, when using mobil 1 or whatever?
