Part of the problem with getting a new plane after having the same old one for over twenty years is that you have to learn all it's special quirks! The O-320 in my Yankee was very boring - put in 7 quarts, and 25 hours later, drain out 5 and put in another 7...Yes, the sump held 8, but it immediately blew out anything over 6.8, and then methodically sipped it's way through the rest.
New plane - gotta learn new numbers! With 90 hours on the new O-360 in the RV-8, she is burning through about a quart in ten hours. It also seems to dump anything over a little less than 7, so putting in a quart when it is at 6 makes me need to add a quart at less than 10....but how low below 6 is reasonable? My instinct tells me that I can probably let it get to 5, but my wallet reminds me this is a brand new engine!
Sorry for being so long winded getting tothe question...what do folks that have been flying their O-360's consider to be the lowest you'll let it get? And I'd love to hear Mahlon's opinion, since his folks built the engine! (I figure I might not be the only one interested in the answer, that's why I'm posting, rather than private emailing...)
The same question on the Grumman Gang would have brought at LEAST a week's worth of debate!
