So there's no oil in a Mac, but this is a pretty diverse crowd here, and I've seen lots of good advice dispensed on all kinds of subjects.
I have what I consider a philosophical question about motor oil. My grandmother passed away and left me her car, a 2001 Buick Century with 16500 miles (yes, 16.5k) sporting a 3.1L V6. It's a nice car, very comfortable, and from my tests has a max gas mileage at about 35 mpg. I'm coming up on the first oil change for me on this vehicle. So you know my question: do I use old-school dino oil or some variety of synthetic? I've always used dino oil in everything except my '02 TDI Jetta (which is obvious in its need for synth).
I tend to keep my cars for 8-10 years, and also tend to roll a lot of miles (25-30k/year). I've always had good luck with plain oil, but I'd like to give the Buick every chance not to screw up that is cost effective.
What's the concensus?
