Detergent oil

I run straight 30 weigh Kendall oil in my car and then top it off with Marvel Mystery Oil and all has been good and quiet.

Kendall! Don't see that brand in this part of the country. When I was a kid in the early '50's Kendall advertised in magazines like the Saturday Evening Post. The ads featured a hand raised with two fingers making a "V" sign and the slogan said "Kendall! The two thousand mile motor oil". The usual interval was 1,000 miles so I guess you cut oil expense in half! Now my VW Diesel goes 10,000 miles between changes.
