Fuel, fuel and more fuel

[sandspider]

I use Makita 2t oil, which i doubt is as good... (But none of my kit is top end)

 

I treat all the petrol I buy, then it's good as pure petrol for the mower & wheeled strimmer, and when I add 2t oil it's good for the 2 stroke kit too.

For the infrequently used machines I use alkylate/Aspen or similar.  I just run and store them (indoors) with whatever fuel is left in the tank.  Never had any issues. Just like the 'good-old-days' when we had proper petrol!

 

I use E5 pump fuel in the frequently used strimmer and chainsaw with oregon two stroke oil at 40:1. I am literally using both every few days.  At the end of the season, I run the strimmer dry, run with alkylate and then store.  I check the carb and lines on the chainsaw every few months - so far all the carb has required has been a clean out with carb cleaner.

 

I think fuel stabiliser is snake oil.  Use fresh fuel.  Pour out your fuel after using machines in the rain.
