OK; the shot of oil is intuitive =96 and = I'd think perhaps you'd want a shot in each 'chamber'. 
 
I never tried that but it wouldn't hurt. = Lots of smoke...............

In winter I have used several shots (from a pump style oil can) of e= ngine oil and 1/2 cup of hot coffee in each housing.

What does the hot coffee (basic= ally water) do?  I'd think it would just foul the plugs.

Adds a bit of heat, a= nd takes up volume, raising the compression ratio. unsticks the apex s= eals. The rotary acts like a piston engine with w 4 1/2" piston a= nd one 14" long compression ring with 4 end gaps. So extra heat of com= pression can keep a bit of the fuel in vapor form.
It will burn as dropl= ets but too slow to spin the engine. Like a diesel needing glow plugs in th= e intake and in some cases, glow plugs in the head to heat the air, or you = get no start.
 
In olden times just a= constant stream of WD-40 would keep it running until it got some heat in i= t. The newer safe formula is much safer.
 
They leak compression= fast as they go into compression, so, the cranking speed must be high. All= of this is for winter time. This is more a problem (flooding and wetting t= he plugs) in the Renesis than other types. There were several reburns on th= e controller trying to solve this. Too many new cars being towed to the dea= ler for no starts in sunny California. Duh.......... With the periphery exh= aust port, one complete revolution dumped the excess fuel, and a few more r= evolutions at full throttle, dried the plugs. In the Renesis, the excess fu= el is wiped over the plugs again and again.
 
Try wide open throttl= e and no injection at all for a bit to try to dry the plugs. Done with the = brakes manned.
I build with zero end= gap on a fresh engine. Starts are instant. Even when cold........even with= the battery down.
 
They used to have two= side seals and 6MM apex seals. They used to spray in antifreeze from a bot= tle on the firewall, when cranking in cold weather to unstick the apex seal= s when frost would glue them in the bottom of the groove. <= /font>
