Dear Paul,

Referring to my earlier message about our purchase of Beaver&Wankel: Weare confused about the right/best lubrication oil types. Another this type engine was destroyed in Finland because the lack of oil or bad oil. So we don't want to run our engine before we are sure about the right type of lubrication oil and gearbox oil.

1. Wankel Norton Aerotor 80 twin rotor engine, model P62, 80 hp (year 1990?/ srno AE 1742-9): In brochyre recommendation is Castrol A545 (synthetic), Nobody knows anything about this oil type here!, What could be the best alternative(s), Mobil-oil type? (someone told about Mobil Pegasus 385 or 485 but they are not very common either?).

2. What about gearbox oil type? (should be changed after every 2 years or 150 hours).

3. And Spark plugs Champion UG 501 PV or UG 80. Other alternatives?

4. Does anyone have the Engine maintanance manual for this type of engine.

Most grateful of any help here in remote Finland!

The oil metering pumps sometimes fail so we mix one ounce of synthetic liquid cooled 2 cycle
oil with one US gallon of fuel. I use the Walmart brand here in the US.

The Norton is a roller bearing engine so you may need more oil per gallon.
We have found that up to 4 ounces of oil per gallon does not seem to hurt
the spark plugs.

BTW Heikki Kovalainen and Kimi Raikkonen  are two of my favorite F1 drivers.
What is it about Finland that breeds such great race drivers for being sosmall
a country?  I flew a VW powered motor glider over there once about 25 years ago.
