I like the stuff, but I've seen/learned a few things
A) a vacuum pump helps get the water vapor out and oil looks good longer.

b)I need to take my carb apart more often and clean, have had a few rust/corrosion issues(pump springs, steel button on the pump dia.,white fuzz/goop) now I pull it apart every few months. A little lite oil on the block gasket to main body helps that area to stay nice.

C)It takes longer to build heat in the engine warm it up early in the lanes, and don't go to the line cold. Sure is nice when you are hot lapping in hot weather.
