Curious about my oil consumption and how it relates to the group as a whole. I'm typically burning a little less than a quart an hour in my Housai. About 250 hours since first overhaul. Occasionally more. How about you?

About a quart an hour for me as well. 285 HP Housai ~ 100 hours since
overhaul.

That sounds about right. My CJ is about the same, although I think the majority of the "burn" is leakage that I wipe off after every flight. JB

If you are getting "most" of a quart an hour as blow by, something's not right. A little oil goes a LONG way. A clean running engine should leave a residue on the belly, but visible oil suggests a leak, acro with zero or less G, or a ring problem....

1 quart = 0.946 liter. My M-14P has burnt about 1 liter per hour since new. Every M-14 (except for one) that I have worked on burnt that much or more. Nothing wrong with that amount of usage unless you see it leaking out all over the engine compartment obviously. I have been told that filling the oil tank all the way to the top and then doing hard acro is not a bright move as it will spew oil everywhere. I have found personally that this seems to be true, especially with negative G stuff. When planning that kind of flight, I usually plan on having a total of 9-10 liters showing on the stick (these are short flights and the oil is checked after each flight). There are also a few folks who claim less oil consumption and lower oil temps when doing hard acro in hot weather switching to straight 60 weight oil. I haven't tried that yet, but plan to. Not recommended for cold weather ops of course.
The one exception to this usage was an specially modified M-14 that used gapless rings and re-machined valve guides with "O" ring seals. The pistons had also been changed with a tighter tolerance and a 3 ring piston vice 4. This beast ran cool, the oil stayed clean and did not turn black, no oil ran out the pipes after flying, and oil usage went to close to ZERO. Tom Johnson's YAK-50 has these mods, and so did Sergei Boriak's Suke. I think Bill Blackwell is offering this mod now and boy would I love to be able to afford it.

My M-14p is using about 1 1/2 qts per hour. Oil consumption has gone up since new but that was 1500 hours ago.. All rings (except # 9) have over 1000 hours on them. Low cylinder is 72/80. I use nothing but 60wt detergent oil and 50wt when it gets a little cooler. Have 10 micron filter which is still very clean (no metal) after each change. I run cruise at 2000 rpm/28mp and acro at 2400 rpm and 32-33 mp. I have the top end of the governor set at 2850. Temp is usually at 150 to 160C cylinders and oil temp out is around 100C.
I am planning to go to gap less rings, flat head close tolerance pistons and perhaps with "O" ring valve seals. Because of the high time on the bottom end, I don't like the idea of boosting up the horsepower to God knows what. Besides money IS the constrainting factor. Hopefully if my retirement fund turn around enough to make my wife feel comfortable, I hope to do this later this year. Maybe this "top" over haul, will see me though my old age.  )
BTW, Back from Sun&Fun. Three years ago was the "Hay Year". Last year was the "Mud Year". This year will be known as the "Soot Year". The airport authority at LAL decided to burn the aircraft tiedown area after cutting it and not finding any one to bale the left over hay. Of course the rains did not come! The result was blowing black soot everywhere. Just walking though it kicked up black clouds. People looked like Al Jolson look a- likes. I caught sight of the T-6 guys right after starting engine for the show. It looked like all of them had way over rich mixtures. A number of WBs left early because of it. As it was the count from last year was down 30%. Saturday's crowed was OK but the earlier part of the week was way way off.
RPA again put up the most A/C. but our numbers were way down too. The most we put up on one day was 8. The last day we put up 6 but that included 2 orphaned T-34 guys. The T-6 guys were lucky to get 4 for the "Missing Man" salute.
Boggs has tighten up the show and run-in lines. It requires some very precise flying on the part of the lead. Flying with my canopy open, I had the "experience" on landing of feeling the blast and the HEAT, when "Dynamite" set off a charge between me and a Wildcat flat out and level with me, on a "strafing" pattern. Great fun.

If the engine is burning anything over 1L an hour isn't that something to be concerned about? Our machine C in cruise config is using about .700L an hour (700mm and70%).
I found that 10L on the mark was ideal for akro although the book says taht is a min C and generally ran up to 12L for cross country.

I don't think Bill has a web site believe it or not. I do think that he did some advertising in a recent Red Star newsletter though... you might ask a member. He is also offering a new exhaust design that basically is designed around single tube header//collector concept from race cars. In fact I think his whole approach began from that starting point. I have some experience with drag racing engines and his mods have the look and feel of some of the same things done to typical race engines. The Russians used loose tolerances with rings that hopefully would expand and seal once hot. They do actually. Bill's approach was to use a slightly higher compression piston, which I think was something around 8.4:1 or so, then re-machine the valve guides, then use closer tolerance pistons with the gapless rings. Just with the pistons, you could probably expect a 20 HP or more gain on a M-14PF. With the new exhaust system, I would expect he is getting somewhere near 430 HP or so out of a M-14PF. Tom Johnson also moved his oil cooler to the wing root. His airplane is simply over the top. His engine was a prototype for Bill's mods, he has the MT FW-190 bladed prop, he had CUSTOM tube headers installed and they are simply just GORGEOUS. I have no idea what his engine puts out, but it's dramatic. Tom is good friends with Bill Blackwell... suggest you talk to him personally.

Andrew, read what Richard Goode said. I am not an engine expert. I have a fair amount of experience as does a lot of other people here. Richard is ....to me .....the man who knows every detail of what the Russians themselves say, other than maybe Vladimir Yastremski... but regardless he says over 1L/hr is fine. I would trust anything he says.
I agree on your engine oil levels!

.ExternalClass DIV {;} Andrew C read what Richard Goode said. I am not an engine expert. I have a fair amount of experience as does a lot of other people here. Richard is ....to me .....the man who knows every detail of what the Russians themselves say C other than maybe Vladimir Yastremski.. but regardless he says over 1L/hr is fine. I would trust anything he says.
I agree on your engine oil levels!

.ExternalClass .EC_hmmessage P {padding:0px;} .ExternalClass body.EC_hmmessage {font-size:10pt;font-family:Verdana;} If the engine is burning anything over 1L an hour isn't that something to be concerned about? Our machine C in cruise config is using about .700L an hour (700mm and70%).
I found that 10L on the mark was ideal for akro although the book says taht is a min C and generally ran up to 12L for cross country.

.ExternalClass DIV {;} 1 quart = 0.946 liter. My M-14P has burnt about 1 liter per hour since new. Every M-14 (except for one) that I have worked on burnt that much or more. Nothing wrong with that amount of usage unless you see it leaking out all over the engine compartment obviously. I have been told that filling the oil tank all the way to the top and then doing hard acro is not a bright move as it will spew oil everywhere. I have found personally that this seems to be true C especially with negative G stuff. When planning that kind of flight C I usually plan on having a total of 9-10 liters showing on the stick (these are short flights and the oil is checked after each flight). There are also a few folks who claim less oil consumption and lower oil temps when doing hard acro in hot weather switching to straight 60 weight oil. I haven't tried that yet C but plan to. Not recommended for cold weather ops of course.
The one exception to this usage was an specially modified M-14 that used gapless rings and re-machined valve guides with "O" ring seals. The pistons had also been changed with a tighter tolerance and a 3 ring piston vice 4. This beast ran cool C the oil stayed clean and did not turn black C no oil ran out the pipes after flying C and oil usage went to close to ZERO. Tom Johnson's YAK-50 has these mods C and so did Sergei Boriak's Suke. I think Bill Blackwell is offering this mod now and boy would I love to be able to afford it.

Curious about my oil consumption and how it relates to the group as a whole. I'm typically burning a little less than a quart an hour in my Housai. About 250 hours since first overhaul. Occasionally more. How about you?
