Radial engines I worked on used up to 8 gallons a flight so they effectively changed the oil by burning it. On the small helicopter engines they used a running in oil which was changed after the engine stopped gobbling it to a thicker detergent oil at about 50 hrsThen every 100 hours the oil filter was cleaned but no more oil changes. |

The current trend is to eliminate that critical additive so that the newer/cheaper catalytic converters don't become contaminated with 'carry-over' oil in the exhaust- and become ruined more easily. The new cats are cheaper with a vapor-blast of the rare earth elements, instead of pellets and/or honeycombed matrices, and they cannot take much abuse. Ergo:the need to remove the 'potentially' contaminating factors from the engine oil. BUT - the ZDDP is critical as an extreme pressure lubricant for the cam and lifters/followers and without it engines of that design from about 2006 and backwards (in many-most situations) will die a horrible death without it. Camshafts and lifters will wear rapidly if not instantly and toss the shredded metal into the oil system and that's never good. California (natch!) was the first to indict these oils with ZDDP and someone got paid off in the automotive emissions testing and criteria design bureau, and it's been downhill since. Thankfully, the oil WITH the critical elements is still available in other states, and they don't seem to have too much worry about changing their standards at the moment. All our cars but my wife's vehicle, require the ZDDP - which I can still buy here in tanker trucks full. |
