The D handle advised 33:1 fuel, I ran it on 25:1 and when I mentioned this to the guy at the shop when buying the bull handle machine he said they actually verbally recommend 25:1.
The bull handle machine states 50:1, I'm wondering if I should richen this up a bit given that it is a chinesium machine, and the metalurgy isn't as good as say a Stihl - I'm thinking 40 or even 35:1?
Also, is there a better oil than the Castrol Garden 2T (I notice Penrite's the same price at Autobarn) and does the oil have a shelf life - I only mix a litre at a time and have a small yard, so my bottle of Castrol is five years old.
