you guys know I test constantly and oil/tribology is my thing so here goes. I know the gasoline today is shit. Very dry and poor quality. Throw in
Very interesting thread above. Adding marine 2 stroke oil with TC-w3 in a ratio of 1 oz to 5 gal gas (1:600)
Since I was building a BBK on my Grom, I figure I would test it out.
First thing I did was replace the stock piston (pictured) with a DHM 186 cylinder and piston using the stock head.
Started using the oil mix with the new piston, cylinder and old head.
Decided to add a Finbro ported head so took off the old head and was amazed to see how clean it had become.
Note the piston pictured has carbon buildup deposits. The head pictured looked just as black and crusty. That is what the head looked like before I started using the 600:1 oil addition to the fuel.
The photo of the head is how it looks now removed from the engine having been run for 300 miles on the additive. Carbon deposits are gone.
Going to keep running the mix.
