I've got a petrol lawnmower and a petrol hedge trimmer.
Now I'm not telling you that to brag!

Lawnmower likes its petrol straight and hedge trimmer prefers a dash of oil.

Rather than have two cans on the go could I just have one 'petrol plus oil'
can and refuel both machines or do you think it would upset the lawn mower.

This also means that I get a faster turnover of petrol so that it is less
likely to go stale.
