Engine Life - how much do you gain

[eightsandaces]

Flat 6 oil sounds intriguing, hey I have not seen an engine cracked open in a while. I can tell you that back in the day I saw some severe sludge inside engines. I fully understand that the newer oils have different properties, however, in general more frequent oil changes including filters are the way to go. I'll be very surprised if Jake's report says different, the factory interval is too long, I've never followed it since having the car from 14K. I change the oil and filter every year which equates in my short driving climate to around 3, 300 miles. Overkill? Perhaps but if you consider how much cheaper it is for us to change the oil than someone going to the dealer it's still a huge bargain and IMO, cheap safeguard of engine longevity, especially in a car that sees Mr. Yellow line now and then.
