Which basestocks burn cleaner, dino or syn?

[Chris A]

My engine burns 1 qt per 800 miles. I'm not presently concerned with this consumption. I'd like to know if I should be running a dino or syn oil for less junk around the rings and combustion chambers.

I also skimmed through the "which oil for cleaning up a motor" thread and was shocked that noone said running a deisel oil would be bad for a oil consuming motor. I thought that the high ash content is a big no no for oil burning motors.

Update:
I called Mobil and was told that the syn burns "cleaner" (ie leaves less carbon behind) when it gets in the combustion chamber.

I did not ask about the diesel oils.

Synthetic oils will burn cleaner. I think the cleanest burning one's are the ones with the highest ester content. At 800 miles/qt, running a synthetic will get pretty expensive.

I don't consider an extra $5 a month as getting expensive. If I were really worried about pinching pennies, I'd have a small 4 cyl engine I could burn 89 octane gas with. I could probably save $100 per month from the gas price and mileage savings.

Would cleaner burning oil equal to an oil with less ash content? If so would an ashless oil be the best for an oil burner.
