There are spots in the engine subject to wear where the local temp can

get

to
500 F and that is where Mobil One pays off. Probably mostly on start

up

when bearing surfaces are nearly dry of oil. No doubt about it...

there

are fewer such spots in a rotary.

Mobile One makes 15-50 and that is what I use.

Paul,

Is that in the aircraft or the RX-8? i.e., is the Mobil 1 oil
appropriate for a rotary engine, where oil is injected into the ports?
Or do you have a separate oil supply for the metering oil pump?

Thanks and regards,

Rob Weinstock

Keep reading Rob. Some of those questions have been just answered. As far as the 
separate oil tank is concerned contact:

They have separate oil supply adapters.
