Is there a major difference between 2-stroke oil for outboard motors vs
mowers? The price diff is considerable.
I can remember one guy who used to mix straight 30 grade engine oil with
petrol (25:1) for his old Victa lawnmowers which were still going strong
after 20 yrs,...what is the story here? How come a water-cooled outboard
needs more expensive oil compared to an air-cooled garden-tool?
