Derek: I use AeroShell, change it every 25 hours, and send it off to Blackstone. And whine a lot about it using a quart every ten hours.

Most GA engines are between 25 and 45 years old and are virtually unchanged from the original designs in the 50s.

I use AeroShell or Phillips if I recall 20/50 and change every 25 hrs but did not burn oil on the last motor.

I know about age - last plane motor was late 70's (to a design from mid 1950's) and had 5000+ hrs SNEW. New plane is 660 hrs SNEW and is from the 90's (but still a 45 year old design)

Ah yes 8.5L of torque and a 2,800 RPM redline in a flat 6.

My Mechanic recommends every other oil change for lab time.

What are you flying again?

heh. I was at the EAA show in Oshkosh WI this past summer, and some company was promoting their kit for using subaru engines in planes.

I wonder what would happen if you put one of those Lycoming engines in a Subaru....

Maxwell something or another, in Marysville Wa or so? There is a place up there on the side of an airstrip doing the Subaru airplane engine thing.

Welcome to the cult of JVL drink the koolaid or be banned.

I had my A&P, and worked for a tour company. We had a fleet of Cessna 206's, 207's and 402's. We did oil every 50 hrs, cut the filter every oil change, and send to the lab every 100 hours. That 206 was my favorite airplane to fly. Climb out like an elevator when empty. Good times were had on "ferry" runs skimming lake mead in a 402 at 10' off the water.

Sean, where did you get your A&P at?

I took my A&P at clover park there in Tacoma back in 93 I think!

Good times!

We use a oil analysis lab for testing in my line of work. Costs $30 for a sample and they tell you EVERYTHING you could ever want to know about the oil (viscosity(s), aditaves %, Moisture, Acid levels, Metals -all types-, etc etc etc). We send in a baseline of new and referance it from there. They even give us advise on what is good and not so good. I am not a car owner, but I would pay the $30 for a sample a few times a year to see whats in and not in the oil anymore.

Bryan, don't be silly. OBVIOUSLY I could do an analysis on the oil through Blackstone or whatever it's called, but that would require EFFORT.

Pretty easy for me to type a couple of words via the keyboard and shoot it off into the interwebs

Definitely has given me food for thought. I think I'll get an analysis done after Rocky to see if my two event hypothesis is accurate and go from there. I sincerely doubt the 90km's of stage at Cochrane was sufficient to put a hurt on the oil, especially considering the rally was one big opportunity for sufficient high speed, cold airflow.

Very fortunate actually, we had a great Vocational high school in Las Vegas, so I graduated high school with an A&P.
