Sears Snow Blower Question

[Piscator]

I add sta-bil every time I get gas. I leave what is left in the mower and have not had a problem. The small engine place I get my stuff from did tell me to change the oil at the end of the year so that the dirty oil doesn't get a chance to let the particles settle to the bottom over the winter as it can form a sludge. I guess it is a good point, why leave dirty oil in there all winter.....

everything gets sta-bil all season.. and run out of fuel when the season is over..the oil should be changed at the end of the season.. reason being... the acids in unburned gasses in the crank case can corrode the aluminum block and put pits in the crank shaft and connectiong rods... most of those engines are not sleeved bearings and have little tolerance for wear of low grade oil..


a shot of mystery oil( or fogging agent ) in the spark plug hole and a slow pull to distribute it is not a bad idea either..

sears is pretty good with their power products.... they replaced two pumps on my pressure waher.. in the first two season I owned it... no questions.. no cost to me..

Interesting point my boat mechanic told me. Changes the oil in the fall at winterizing time because the old oil will have some acids build up and ultimately cause problems in the spring. Makes sense in a 4 stroke because we don't fog the motor so the oil will be clean at fire up.
