Upper Cylinder lube

Just thought I would ask...Who use UCL ? which brand ? I myself already use it and believe it is a good measure...with todays gas I feel it is a good thing...Our trucks use the 10% meth stuff....and with all the EPA crap the gas of today is not the gas of the 70's....

I use Lucas but I think I may switch to 1 can of sea foam every oil change then a few oz's of Marvel every tank full....Upper cylinder lube made me a believer when I owned Harleys....I and a friend with our wife's permission of course went out got new Road Kings...I used UCL from the first tank and he didn't.....when we tore his down to put a big bore kit on it 15k miles later ..his valves where pretty sooty and you could see some wear marks....not bad but you could tell it had been ran...when we tore mine down the next fall ..mine was clean and looked in very nice condition.....All I used was the Marvel Mystery oil every tank and I would do a half can of sea foam twice diring the season just to keep the injectors clean.....

 

Not needed unless you just feel the need to spend money.

 

^X2. Our trucks have been designed to tolerate up to 10% ethanol. Small engines in motorcycles and boats are a different story. Not surprisingly, most of the ethanol-free gas pumps in Ohio are at marinas: http://www.pure-gas.org/index.jsp?stateprov=OH
