Continental's recommended time between overhaul (TBO) for these engines is 1,800 hours of operation or 12 years in service, whichever is reached first. The standard certification for the C90 and O-200 specifies Avgas#80.2F87|Avgas 80/87 as the mi |

two-speed supercharger. This engine had lubrication and carburettor problems in extreme cold conditions. * '''ASh-82-112 (M-82-112)''' - Improved M-82-111 with longer Time between overhaul (TBO) and better reliability.

reduce the engine's relative high shaft speed (5,800 rpm for 100 hp versions) to a lower speed for the propeller. The 912 series have a lower time between overhaul (TBO) than traditional engines but are more fuel efficient than similarly sized engines (e.g., Continental O-200). Effective 14 December 2009 912 engines have had their recommended TBO raised from 1200 |
