It has proven to be a good racer's tip. It lubes the top end/cylinders and brings the combustion temps down a tad.

The Ethanol has a tendency to wash the lube oils away.

My other secret weapon is SeaFoam. Great stuff, especially for 2-stroke outboards that don't see a lot of high RPM use. It is a stabilizer and it helps clean carbs/passages and cylinder carbon build up.

The new Stabil for marine use is de-rigeur for winter storage.
Seafoam is awesome. There have been several threads on it here.
