moly slip oil additive

[namgaj]

I know that there has been some debate on the oil additive subject.
I carried out a simple test recently and added some to the engine oil when running. There was an instant increase in rev's presumably due to reduced friction.

After this submitted car to a 1000 mile "test" (usual driving conditions over a 3 week period). It recorded 32.5 miles per gallon. (its a 4x4 diesel on semi synthetic oil) when in the past it had always returned around 29.4

I dont know why the oil companies dont include this stuff in the oil themselves but at this time it does seem to work.
