Motorcycles and Aircrafts are two of the main vehicles that uses an air cooled engines. They use this feature since they normally have smaller engines then a normal moving vehicle.
Most small vehicles do not use diesel engines.
Combustion Engines can be made either air-cooled or water-cooled. Radiators are only needed for water-cooled Engines. Small two stroke Engines are used in Bikes.On that external surface Fin type arrangement is made.This is enough to dissipate the heat from the engine as which is small
During WW2, naval aircraft preferred to used air cooled radial engines. The US Army Air Corps (Force) preferred to use the in line liquid cooled engines. Air cooled engines were tougher (more durable) because they were more simplier and less complicated; they didn't have extra hoses and radiators, etc. and could keep flying when they were shot up. Liquid cooled engines could have their hoses shot out, which would cause the engine to freeze up (stop), then the pilot would have to bail out; scratch one expensive airplane.
Briggs & Stratton small air cooled engines use SAE30 weight oil or SAE 10w30 if they will be operated in cold conditions. I highly recommend you use Synthetic oil in any air cooled engine.

Air cooled, umm it depends on what type of engine you are talking about, if its a motorcycle it would be 10w-40 made for an air cooled small engine.there really a diff. if its new go 10w-30 older i would say 10w-40 Synthetic
From 1972 to 1979 the VW micro bus uses a type IV "Pancake" version of the air cooled flat four motor. Pre 1972 VW buses use the upright air cooled motor identical to the versions used in the VW Beetle's of the era. VW then experimented with a water cooled version of the flat four engine(Wasserboxer), this lasted a few short years and VW moved all vehicles to their water cooled inline and similar standard engines.
One type of antifreeze that can be used is Pentosin PENTOFROST A1. Pentofrost A1 is an antifreeze for Asian vehicles in water-cooled engines.
Use exactly what the manufacture of the engine recommends. Most small air cooled engines of this size use SAE 10w30 full synthetic.
Most motorcycles are liquid cooled the benefits are better cooling efficiency. Notice the stratospheric redlines on modern race bikes as the reliability of internally parts is increased. These engines are also more streamlined with no cooling fins but have more parts and a radiator. A fan will help cool the bike when it's not moving. The best use of liquid cooling is in racing or high output machines. An air-cooled machine is reliable at lower power output has less weight and less parts. By many, air cooled engines are considered better looking. The main use of these engines are in cruisers and dirt or dual sport bikes.
Petrol is gasoline and most internal combustion engines, thus most vehicles, use it.
