Default RE: Oil Test Summary by rc bugman

Mobil 1 MX2T + injector cleaner

The final test was to take Mobil 1 MX2T which formed carbon in the previous
test and mix 2 oz/gal of injector cleaner into the gas/oil mix to see if the
injector cleaner had any effect on carbon formation as suggested by one
modeler.

We ran the engine for 3.5 hr at full throttle. Engine rpm returned to the
5900-6000 rpm level indicating a better ring seal that Amsoil 100:1 at 100:1.
With the air temperature 24 degrees F, we were only able to achieve cylinder
temperatures of 190-195. In spite of the lower temperatures, we still had
significant carbon formation very similar to when Mobil was run without the
injector cleaner and the cylinder temperature was higher. After 3.5 hrs, we
pulled the plug and looked with a flashlight. Since we could see carbon
formation on the piston, we stopped the test, pull the cylinder and took
pictures.


Remember, this carbon formation is just in 3.5 hrs rather than 6 hrs.
