The origional owner changed it around the 9,000 mile area. Based on what he was told, he was changing it early.
The computer would have had him go 12,000 miles between changes.
He used Mobil One. His last change was at 88,000. I added a quart every 800+- miles to 95,000.
I changed it at 95,000 and it has used no oil as of 98,100 today.
I wish I knew why. I wrote penzoil - maker of gummout.. no answer. Some stuck emission valve I guess. I hope by sprreading the word, I can save people anguish.
