I have a generator (cheap end) never used for 7 years so going to get it
working and sell on.
I only intend to mix up a ltre of petrol to a small amount of oil for
the 2-stroke mix. Just to get it working for test purposes.
For my purposes could I use either oil I have for the car or some oil I
have for the chain saw.
for my short running time would the oil be that important?
