I was curious about what you were saying regarding carbon deposits inside your valve covers. So I called the Mobil tech line, 1-800-662-4525, to ask them what they thought. You might want to call them yourself, but I was told that they have never had a question, comment, or complaint similar to yours. And as far as deposits are concerned, their rep stated that the use of their oil decreases the formation of them, and cleans them out of your engine. You can also get more info by going to their website, http://www.mobil.com.
Hey, Larry, they also manufacture a synthetic DELO called DelVac 1... Use that in your lawn mower
