Now that your car is used to the champagne of oil will it ever be happy with the beer and pretzels from the dealer.

Mobil 1 must be getting very popular. I was at Walmart picking up something for my daughter and priced Mobil 1, I was surprised to see just about all the shelf space empty and all other oils well stocked.
They say that the oil is good for 20,000 kms, but cars sure run better after a fresh drink. (as do the drivers after parking the car)
When I change my oil I'll do the same as you ie a short 1 k drive. Down to Tim Horton's to get a coffee to enjoy as the oil empties.
Now if Pela will come up with a way to suck all the brake dust from the front wheels.
