I've heard about stripped threads on the oil plugs, but I've never had a problem (that I know of). I used to go to Valvoline Instant Oil Change (pre-Xfire). I paid for the upgrade for fully synthetic oil but then wondered how I'd know if they actually used the 100% syn or not. I didn't watch them too closely. I'll know better now. I haven't had to change the oil in the X-F yet. Was planning on doing it myself, but those jiffy-type places are convenient. I know I don't want to pay the inflated price for their oil at least.

The dealership I bought the car from has this gimmick - if ALL scheduled maintenance is done there, they'll slap brand new rubber on when the current tires wear out. Sounds great. Trouble is, the dealership is over an hour away, and the oil changes are at the typical bend over price. Here's the deal in their words:

"In Order to receive your replacement tire rewards, you must;

Have ALL Factory Recommended Service performed at OUR Dealership AND
ALL recommended services must be done within 1,000 miles or 1 month of when due AND

Tires must have been driven at least 25,000 miles AND

Tires must have reached a tread depth of no more than 3/32 with uniform wear."

A minefield of conditions. Factor in the time & the cost of gas driving up there and I'm not sure it's worth it.
