been running QSGB and citgo supergard for life of the car .....,,,, 280 K and Blackstone says A-OK
2.7 is a very durable motor, I run between 4 & 5 k OCI on this car as the car sees severe use in the chicago metro area , and my sons 03 santa fe is tight at 156K up in the frozen land of 10,000 lakes at school.
