What Dustin said.

I cant help but notice that nobody here ever asks if they should run straight, non detergent 30W turn of the century vintage oil in their modern 2 stroke engines. Or, straight non detergent 30 weight oil in their new, twin turbo pickup engine. Just mix it up like they used to do when Grandpa was a little kid. A lot of engineering time has been spent in the last 125 years improving sheer, anti corrosion, EP qualities, improvements in ester chain length and strength, etc, etc, etc, and we still have guys that want to use 3 in 1 and Vaseline.

Ick.

Best,
Ted
