<p>Thanks for the input. I'm also using the original oil cooler mounted at the front of the cowl. No problems with it after 400 hours. I did change out the lines with teflon lines a few years ago.Your temps are very close to what I see as well. </p>

<p>Flying with UL 350i in our 650. Summer day with 90+ temps, oil temps are 185 - 190. On hard climb out can get me to 210. Obviously, winter days here in Nebraska are not a problem. Using Dynon monitor for these numbers.</p>
<p>Still using UL supplied oil cooler. Have the Aero classic style cooler in a box on the workbench. Have not taken initiative to try to install. Cooling not a concern for me, but still thinking of reports of failed oil coolers in flight. I have 370…</p>

<p>Either my cooler is good and it is never going to be a problem or else it fails the next flight.</p>

<p>Thanks for that info. As to year of mfg I think it was late 2012 or early 2013. We installed the engine in March 2013.</p>

<p>I had all kinds of high oil temperature issues using an "after market high performance" oil cooler on my Rotax 912 in the CH601HD. Instantly 3 months of grief was gone with the installation of an Aero Classic aircraft engine oil cooler. Just my 2 cents.</p>

<p>David, glad to hear you are happy with the engine at 400 hours. Bodes well for the rest of us UL owners. Up here in central Maine I'm experiencing a range of oil temps due to a couple variables. Changed out factory cooler for an Aero-Classic cooler which helped notably when flying this summer with floats and OAT close to 90F. Dropped oil temps back down to 190-200 range from the 200-215 range. Now back on wheels/skis for late Fall and Winter I have blocked off approx 2/3 of my oil…</p>
<p>David, glad to hear you are happy with the engine at 400 hours. Bodes well for the rest of us UL owners. Up here in central Maine I'm experiencing a range of oil temps due to a couple variables. Changed out factory cooler for an Aero-Classic cooler which helped notably when flying this summer with floats and OAT close to 90F. Dropped oil temps back down to 190-200 range from the 200-215 range. Now back on wheels/skis for late Fall and Winter I have blocked off approx 2/3 of my oil cooler to keep oil hot and am running 185 - 200F on 30F OAT degree days, near max gross of 1440 # and 2600 RPM. As Winter cools things down even more, I should be able to maintain at least 180-185F on oil temps. I worked last Winter, but that was with the factory cooler. The Aero-Classic is more effective as a cooler and may have to adjust or block off even more of the cooler. If you don't mind, what year production is your engine? Mine is a Nov 2011 manufacture and there has been a few "teething" pains, which hopefully I've worked out by now with 140 hrs on the engine.</p>

<p>David,</p>
<p></p>
<p>With stock oil cooler on a hot (90 degree) day my oil temp would climb past 215 and make like 220 was fast approaching. On cooler days the temps were fine. I expect to install a larger after market oil cooler in the next couple of weeks. My engine is a 350i.</p>
