I concur with checking your temp gauge. Many bad and expensive decisions have been made using incorrect oil temperature gauges/probes. Better that it's reading high than low however.
I fight oil temps every summer with my GP2180. I've also got the Jet Coat pipes and a standard VW oil cooler. I use 240º as an ultimate red line and treat it as a semi-emergency if it ever gets that high. In the summer on climbout it's easy to hit 240º if I'm not careful. I am careful though, and stage climb. In the winter or at altitude my set-up is perfect so I haven't made any changes. I've played with oil viscosity - Steve says a lighter oil will dissipate heat faster but I've seen no difference using lighter oil and have gone back to 20/50 (full synthetic). It's good that you are concerned about the high temps as heat is the killer of VW engines. A Revmaster cooler would be a very nice solution and probably a necessity if you fly two up in the hot season. Since mine is a single seat I can get away with what I've got as long as I watch it . . . and I do. On hot days it's tedious gradually working up to the cooler air above without overheating the engine. What you are experiencing is pretty normal I think. These engines put out a lot of heat when working hard in an airplane. The standard VW oil cooler was designed for car use.
