impressive!
 

Great work Pete - whatever you are doing, keep doing it! :) Do you feel that the cleanliness of your valves is due to running unleaded fuel? Did you ever get around to the oil analysis? What kind of oil do you run? Any additives?

Oil consumption?
 

Hi Pete - what is your oil consumption and what level are you running? Oil separator? Thanks

Mogas....
 

Hi Mickey,

I do think that mogas keeps things cleaner, but I think it is observational and can't quantify it.

Sadly I forgot to buy the oil analysis kit. Maybe next time.

I have only run Phillips XC 20W-50 from hour zero. It has worked well for me.

100 only hours in 10 months Pete? Head my way lets go backcountry :)

5Qts
 

Hi Tim,

I have been running 5 qts since about hour 100. Any more just blows out the breather very quickly - I do not run an oil separator.

I use about 1-2 qt per 50 hours, it has been that way since she broke in. I usually need about 1/2 qt at 25 hours and 1/2 qt at 35 or 40. I just keep it at the 5 qt line on my dipstick. My guess is the viscosity improvers start to breakdown, but I am no petro chemist. I'm sure there is someone here that can explain it.

we tried!
 

Vlad,

We were headed to Idaho - but the wx this week was not tent camping friendly and work got in the way. We have another window in August.

Curious how your plugs look.

have you ever done any measurements on wobble test?

Heya Pete -

I hesitate to call it a full blown separator - it's more of a breather - but it lets me run 8qts without putting anything on the belly and best of all I put it together in an afternoon with metal I had leftover from the build (recognize part of a trimmed push tube? :-) Happy to share more if you'd be interested.
