Arnold 2-Stroke Mixing Bottle (6011-X1-0201)
Arnold's 2-stroke mixing bottle, marked for 1:25 and 1:50 ratios — measure petrol and oil accurately at home for a brush cutter.
In short:The Arnold 6011-X1-0201 is a two-stroke mixing bottle with scales for 1:25 and 1:50 petrol-to-oil ratios. You fill oil to the mark for your ratio, then petrol to the matching line, and shake. Accurate mixing matters: too little oil damages the engine, too much causes smoke and fouled plugs. Use the ratio in your machine's manual; most modern brush cutters run at 1:50.

What it is
Arnold’s 6011-X1-0201 two-stroke mixing bottle has scales for the two most common ratios: 1:25 and 1:50. When we checked in October 2026, the Amazon.co.uk listing couldn’t be dispatched to our location, so check availability.
How to use it
Find the ratio in your machine’s manual — most current brush cutters use 1:50 (20 ml of oil per litre of petrol); some older or budget machines use 1:25 or 1:40. Pour oil to the mark for your ratio first, then petrol to the matching line, close it and shake well. Use fresh unleaded petrol, ideally E5, and a good JASO FD or ISO-L-EGD two-stroke oil. The full table, including 1:40, is in our 2-stroke fuel ratio chart, and the method in how to mix 2-stroke fuel.
Why accuracy matters
Too little oil and the piston and cylinder wear or seize; too much and you get smoke, carbon build-up and a fouled spark plug. Guessing in a petrol can is how most of those problems start.
