912S Oil and Coolant

[RandyL]

Wade,

Regarding oil, the Mobil 1 4T is a full synthetic. It'll work just fine in the 912 unless you run 100LL fuel. I'm told you want a semi-synthetic blend or regular dino oil so as to better manage the lead that makes its way into the oil system. Even then you'll need to clean out your oil tank regularly to keep the lead at bay. If you're running mogas then no worries, use the 4T, good oil. If you will be running 100LL, and if you have a new engine, I'd use the Honda GN4.

Regarding the coolant, you can use either but you are correct, you must flush thoroughly.

Regarding operting Rotaxes altogether, if you are new to them then I highly recommend this video...

I bought one and am glad I did, excellent information. Once I get my engine installed I plan to attend the Lockwood school, but that'll be in '09.

Randy,
Surprisingly I have never seen Honda oil on the Rotax service notices. I know the Honda stuff is the best out there and used to use it exclusively when I rode a crotch rocket. Dunno why Rotax doesn't list it.

I plan on using "drug free" mogas. The Staff Jennings on Macadam sells it and is on the way home from work for me. Plan on getting a tank for my truck to load up every once in a while. The good news is that Mulino plans on getting a tank full of the stuff like Lebanon currently has!

I fly an Aeronca Chief and like to mix the juices for the little 65hp.
