Whereas light weight air cooled transformers could be used on the Engadine Line, a heavy oil cooling system would be necessary for 15, 000 volt operations, and that would greatly have increased the weight of the VZ locomotives.

During its test phase in 2000, when the plane was being flown by flight instructors, mechanical problems grounded the T-6A fleet for about two months because of oil cooling problems on the aircraft's Pratt & Whitney turboprop engine.

The He 100's oil cooling system was conceptually similar to the water cooling system in that vapor was generated using the heat of the oil and condensed back to liquid by surface cooling through the skins of the airframe.

Further revisions to the original design include under-piston oil cooling, a revised turbocharger unit and the deletion of the contra-rotating balancer shafts in the " Z20LEH " engine ( as used in the Astra VXR ), to reduce mechanical losses.

The introduction of air-oil cooling via large radiators known as SACS in the road-going Suzuki motorcycle demarcated the GS / GSX machines from the new technology of the GSX-R machines, however this distinction is blurred somewhat by later models such as the GS1200SS which used the SACS equipped GSF1200 Bandit engine.

Designed to give reliable service under prolonged hard use, the engine featured deep water jackets, an innovative diagonal head-to-block joint that allowed for oversized intake and exhaust valves, thermostatically controlled oil cooling, copper-lead bearings and a hardened crankshaft . Triple Solex carburettors and 7.8 : 1 compression and raised maximum output to at 5000 rpm.

But five days later on March 28, 2014, GM announced a recall on the 2015 Tahoe and Yukon in order to fix a transmission oil cooler line that is not securely seated in its fitting , causing the vehicle to stop and rupture the oil cooling line, resulting in the engine to malfunction and catching fire immediately.

If air-cooling proves sufficient for much of the running time ( such as for an aero-engine in flight, or a motorcycle in motion ), then oil cooling is an ideal way to cope with those times when extra cooling is needed ( such as an aero-engine taxying before take-off, or a motorcycle in a city traffic jam ).

The engine features dual overhead camshafts with continuously variable valve timing and increased-authority cam phasing ( increased phase rotation angle ), a high-pressure returnless direct-injection fuel system with camshaft-driven fuel pump delivering 750 psi at idle and 2250 psi at full load, higher-flowing intake and exhaust ports in the cylinder head, electronic throttle control and pistons with jet-spray oil cooling.
