TCP, Declin
Hi all,
A little late boarding the ship, but I'm here for questions. Re Ethanol. I took the Rotech Service course last April in beautiful Vernon, BC. Boy do I have some stories, maybe I post them in the 914 engine failure section. They recommend using TCP if you have to run 100LL. I recommend 25 hour oil changes as the best way to deal with the lead issue. And if you do run 100LL you need a gearbox inspection at 600 hrs. Declin is the same as TCP, I may be mispelling it. It comes in a very handy small plastic container which allows easy dosing and storage in baggage (as compared to a can of TCP). I'm sure Spruce sells it.
Some sludge does build up, but it isn't too hard to take the sump apart and clean it up, at least in the Diamond installation. Remember not to let any air enter the oil line going toward the engine or you have to go through the purging of the oil system. I haven't had to clean my sump as I just end up getting new engines!!
The last I heard Ximango wasn't approved for MOGAS although Rotax strongly recommends it. Maybe Aeromot has approved it. We don't have ethanol up here in a little country town, or at least the last time I tested we didn't. I gave up testing and just use Super Premium unleaded from either Texaco or Shell. I've never had an issue with autogas but remember I'm flying a Diamond and not a Ximango.
