Disadvantages of Two Stroke Engines
I’ve often been asked what would happen if the same 2 stroke engine we use in our favorite outboard motor was transferred to a car or truck, and the answer is the result wouldn’t be all that pleasant. 2 stroke engines don’t last nearly as long 4 stroke engines, and the parts of the engine wear down a lot faster; they’re not meant to travel long distances or be used several times per day. 2 stroke oil is also quite expensive compared to traditional motor oil; a two stroke engine in a car or truck would burn about a gallon of oil every 1,000 miles, and burn fuel less efficiently as well. 2 stroke engines also pollute more than their 4 stroke counterparts.
Despite all of these disadvantages in cars and trucks, two stroke engines still work great for outboard engines and in smaller vehicles like jetskis and snowmobiles.
