But I do have some recent experience/info on this subject. Fortunately, I haven't had problems with the auto gas gumming up the carbs. But I did switch to avgas (100LL) for about a year; for other reasons. Recently, my engine ended up with a loss of compression on one cylinder. Remembering from the past when I've had lower compression aircraft engines (those designed to run on the old 80 octane avgas) that the 100LL, even though it's called Low Lead is actually very high in lead content and will form lead deposits on the valve seats; causing the valve to not seal well, I decided to run the engine some and see how it did. I tied the plane down well and ran the engine for a good warmup and a couple of full power runs. This caused the lead to clear and the compression came back up. I then proceeded with my plans and took my grandson for a ride to an airport about 60 miles south of us. All was uneventful. But when I went to the airport a few days later and pulled the engine thru to feel the compression, after the engine had cooled thoroughly, I now had almost no compression on three of the four cylinders. At this point, I decided that it was time to do two things. One, get the avgas out of the plane, and go back to car gas. And, two, do as I used to on one of my previous planes and add some TCP to the fuel. TCP used to be added to leaded car gas (most advertised by Shell; remember 'Buy Shell with TCP' was the slogan?) to scavenge out the lead. (By the way, lead in this situation can build up lead deposits on the spark plugs and foul out the plugs; saw it several times on my 150hp Lycoming in my Piper Tri-Pacer years back; that's how I learned about adding TCP) Anyway, I ran the engine, on the ground, for about 10 minutes with most of the fuel replaced with auto gas (ran out of gas cans to drain the avgas into) and TCP added. The compression came up nicely on two of the three low cylinders. The third one was still pretty mushy feeling. I decided to take it one spin around the pattern to get the temps up and work it at full power on takeoff. When I checked the next day, after a good cool down, three of the four cylinders were nice and snappy on compression, and the fourth one was almost there; just slightly less than the other three. So, I took it for a 45 minute flight and I'm very happy to say that all four cylinders are nice and strong/snappy on compression again. This is the same scenario that I remember from my past experiences with my Lycoming. Anyway, sorry for the fairly long writeup. I just wanted to pass along some experience that I hope might be of some help to someone. The moral to the story is the avgas will run fine, just be careful about lead buildup long term in lower compression engines. Maybe this info will save someone from tearing the engine apart when the compression drops off for what turns out to be a simple reason.

Fortunately all prior to my first flight. I switched to avgas after getting the carbs cleaned out and I'm not going back. Auto gas starts getting cloudy and gummy very quickly especially her in California.

PST US Subject: Re: Stratus-List: 100 LL vs Mogas From: Andy Fultz I'm pushing 400 hours on mine running avgas and have not noticed the problem s you have encountered. Maybe I should run a tank of Mogas once in a while to "delead" mine so I won't have any problems. I just don't trust Mogas to be the same stuff every time I get it and I know avgas is the same every ti me. Andy F.

But I did switch to avgas (100LL) for about a year; for other reasons. R ecently, my engine ended up with a loss of compression on one cylinder. Rem embering from the past when I've had lower compression aircraft engines (tho se designed to run on the old 80 octane avgas) that the 100LL, even though i t's called Low Lead is actually very high in lead content and will form lead deposits on the valve seats; causing the valve to not seal well, I decided t o run the engine some and see how it did. I tied the plane down well and ra n the engine for a good warmup and a couple of full power runs. This caused the lead to clear and the compression came back up. I then proceeded with m y plans and took my grandson for a ride to an airport about 60 miles south o f us. All was uneventful. But when I went to the airport a few days later a nd pulled the engine thru to feel the compression, after the engine had cool ed thoroughly, I now had almost no compression on three of the four cylinder s. At this point, I decided that it was time to do two things. One, get the avgas out of the plane, and go back to car gas. And, two, do as I used to o n one of my previous planes and add some TCP to the fuel. TCP used to be ad ded to leaded car gas (most advertised by Shell; remember 'Buy Shell with TC P' was the slogan?) to scavenge out the lead. (By the way, lead in this sit uation can build up lead deposits on the spark plugs and foul out the plugs; saw it several times on my 150hp Lycoming in my Piper Tri-Pacer years back; that's how I learned about adding TCP) Anyway, I ran the engine, on the gr ound, for about 10 minutes with most of the fuel replaced with auto gas (ran out of gas cans to drain the avgas into) and TCP added. The compression ca me up nicely on two of the three low cylinders. The third one was still pre tty mushy feeling. I decided to take it one spin around the pattern to get t he temps up and work it at full power on takeoff. When I checked the next d ay, after a good cool down, three of the four cylinders were nice and snappy on compression, and the fourth one was almost there; just slightly less tha n the other three. So, I took it for a 45 minute flight and I'm very happy t o say that all four cylinders are nice and strong/snappy on compression agai n. This is the same scenario that I remember from my past experiences with m y Lycoming. >> >> Anyway, sorry for the fairly long writeup. I just wanted to pass along s ome experience that I hope might be of some help to someone. The moral to t he story is the avgas will run fine, just be careful about lead buildup long term in lower compression engines. Maybe this info will save someone from t earing the engine apart when the compression drops off for what turns out to be a simple reason. >> >> Jim Weston >> CH601HDS w/Stratus, flying it since 1998 >> >> From: owner-stratus-list-server@matronics.com [mailto:owner-stratus-list- server@matronics.com] On Behalf Of ron hansen >> Sent: Friday, April 19, 2013 5:44 PM >> To: stratus-list@matronics.com >> Subject: Re: Stratus-List: Bing carb body >> >> Gary, >> >> Sorry I don't have a carb body for you, but I can also say auto gas gumme d up my carbs causing lots of delays and expense.
