Remember that the paralell valve O-540 in the 182 is a completely different engine that the angle valve IO-540 TIO-540 engines like those found in the Navajo. That being said, the TCDS for the O-540 engines lists a maximum Oil sump capacity for all variants of 12 qt, inclyuding the specific dash models installed in the 182. However that is just an indicatin of how much oil it can hold, the airframe manufacturer may reccomend a different amount as long as it complies with the minimum quantity. The *minimum* Oil quantity for those engines is 2-3/4 quartsicefr8dawg said:If the 540 in a 182RG holds less than 12 qts it's an anomoly for that AC because every 540 I've dealt with has held 12.
I suspect not. The TCDS for the O-540 lists oil sump capacity as 12 qt for all of that series engine, specifically including the J3C5D and L3C5D. I would expect that if Lycoming built an engine with a different oil pan specifically for the 182, it would have a seperate designation.JCJ said:It wouldn't surprise me if the R182 O-540's had a lower oil capacity than other O-540's. In the R182, the engine was derated to 235 HP, and the oil sump pan had to be small enough to accommodate the retractible nose gear.
