[Stutzdriver]

I installed Mobile 1 20/50 on my son's daily driver '84 944 shortly after we bought the car last fall. Everything was fine through the winter, time to change it again soon. No leaks and when I check the oil it is still slightly amber not black like the dino oil. This car has 57,000 original miles and is the envy of all the 17 year olds around.
