I have flown my RV14 for close to 50 hours. Most of that time has been in the winter when temps were a little cooler. On an aggressive climb i would get oil temperatures in the 220s but leveling out I would get back to 180s and could lean the fuel injected IO 390 to about 10 gal per hour. Now Im climbing at 300 ft/min to reach altitude and forget leaning at all. I can keep the temps in the high 190's running the engine at full rich but as soon as I lean I start climbing in temperature. The oil cooler is standard for the engine and I know there are 14's out there that are running with oil temps just fine. Any suggestions?
