Because every professional user I have ever seen is using 10W30 engine

wondering if I am wasting money on expensive bar oil?




Bar & chain oil is a *lot* thicker and stickier than motor oil. This helps it
stay on the chain. Motor oil will work, but it gets slung off the chain pretty
quickly, so you have to replenish the oil reservoir more often. And it makes a
hell of a mess.

Getting slung off the bar doesn't cause the saw to
use more oil. Just means that the bar gets
hotter, unless you dial up the oil flow. 'Course
all you need to do is add a little Motor Honey or
STP additive.


Bottom line: motor oil is cheaper, but you use more of it. I'm guessing it's
about even, price-wise.

That isn't true either, standard brands of motor
oil are more expensive unless you find a really
good sale.
