Every internal combustion engine needs oil for lubrication, but two-stroke engines take their oil regularly along with ...

Since two-stroke engines have fewer moving parts, they are easier to manufacture, and logic would dictate they would be easier to maintain. That couldn't be further from the truth due to friction.

Every new internal combustion car and truck sold in America today is equipped with a four-stroke engine, as are the vast ...

Since two-stroke engines are more polluting, they were banned for most street motorcycles. Still, they are used on lighter applications such as lawnmowers, generators, or go-karts.

The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines ...

Two-stroke engines used to be ubiquitous in dirt bike racing, thanks to their lightweight construction and horsepower. Packed in a dirt bike frame, they make a motorcycle playful in the corners ...

Oil and petrol are miscible. Your 1:50 boat mix is lean in oil. Seagull outboards used 1:10 (smoked a lot and were long-lasting).

On 2 stroke engines, the pistons complete the same action in two “strokes.” A modern 4-stroke outboard motor with the bonnet removed. (Photo/Ilya/Adobe Stock) ...

Which is cheaper to maintain, a 2-stroke or 4-stroke? This depends on the age of the outboard motor and the number of hours on it. But generally speaking, two-stroke engines are cheaper and easier to ...
