brown/grey smoke.....?

[boosst]

i just changed my setting from what was set for a beginner. i now have more throttle and more pitch and i like it:clappp
i noticed today that the exhaust smoke looked more of a brown/grey than white like it had been before. my headspeed is higher along with the changes above. is this normal? i just replaced the ring less than a gallon ago. seems to still have plenty of power and runs fine. just curious.

is coolpower synthetic or castor? i ask as i used to get brownish smoke until i changed to magnum 30. i also used to get a lot of deposits on my plugs. what is the state of your plug?

I think that cool power is syn and Morgan's is the same stuff but with added castor. That's what was told, anyway.
