Thanks for your honesty.
I like the quick-lube places because I don't have to leave my car all day, or sometimes overnight if the mechanics have a long three-martini lunch.
It's true they recommend a lot of BS stuff. Succumbing to a sales pitch, I once tried high-mileage oil. It smelled funny and didn't seem to work as well as normal oil.
What I do is just say "no thanks, I plan to change the XXXX at its next recommended service interval."
Now in the 14th year of my Trooper, most of the service since 60,0000 (when Isuzu dealers went broke after the Consumer Reports tip-over test) has been done by Jiffy Lube. It's amazing how long a vehicle can last when you don't let a dealer work on it.
