I get my oil changed (2003 Chrysler Minivan) by our neighborhood Chrysler dealer. I take my 91 Miata and mama bear's Honda Pilot there, too. They offer a very competitive deal (usually coupons for $16.95) and do it while I wait and watch, drink a cup of coffee, chat up my salesman and check out the new cars. In and out in 20 to 30 minutes and they refill all the other fluids and inspect the tires, brakes, and other systems of the car. The folks are always very friendly, seem conscientious, and I enjoy maintaining a relationship with them. That's rare in business nowadays.
They use Mopar "branded" oil.
Cheers,
Dave
PS -- Be careful what you troll for, the "which oil / filter is best" topic is beat up on almost every internet forum there is . . . and usually without anyone either changing their own mind or convincing others. Very little CONCLUSIVE data exists, and so people either say "my engine lasted for 5 million miles on brand X, therefore it's good" or "my uncle's half-sister's friend's nephew's parole officer's barber's buddy had his engine wrecked by brand Y therefore it's bad".
