I have begun using Liqui-Moly in my Pagoda. After being a staunch advocate of synthetic oil for decades, I have to say I am now convinced that Liqui-Moly conventional oil is the best choice for our old cars. I had crank seal leaks that have miraculously gone away since the switch. I'm still running synthetic in my BMW, Lexus, and Chevy Van. The van has developed a small leak somewhere, so I'm going to try LM in that at the next change.
