With the amount of mix l run through some of my saws each year, by not running expensive 100% ester oils leaves me enough money in my pocket to replace the entire saw. So l do not find expensive oil cheap insurance. lf your capable of cleaning a spark plug, piston crown and exhaust port occasionally their are far better oils to use than full synthetics in any case. There are SOME benefits to synthetics but the negatives far out way the positives. Why would you want to run an oil that promotes blow by in any case. Semi synthetics are where it is at kinda the best of both worlds. l know l go against the grain making this statement and sit in a flame suit as l write this post but there are just such better options out there to increase service life of a saw...full synthetics do quite the opposite (but they are clean). lt's simply a myth to believe they offer better protection. Marketing has a lot to do with this.
Raise the price and they will come. Hahaha
