Default Operating Temp

HELP!!! I live in the Phoenix, Arizona area and as you well know, some days are over the 100 degree mark. Yesterday, it was right at 100 and I noticed that I was running at about 245 degrees as read on my oil bag dipstick. Got me wondering, what's the expected operating temp of a 2005 FLSTFI with a 95 kit installed. Yes, I know that outside temp as well as stop and go or highway driving will affect it. Just wondering if anyone out there can give me a range to work with. I'm running Royal Purple syn oil, 20/50 with an oil cooler and still seeing anywhere from 220 to sometimes 250. Thanks folks, love this site.

195F to 215F is ideal. I have a oil cooler and a Big Sky Fan Kit. I can sit in traffic all day and my temp never goes above 215F.

I do believe normal operating temperature for TC engine is about 230F.

BTW, This is a big reason people use synthetic oil. Dino starts oxidizing at about 250F. Synthetics can easily go over 300F. Cheap insurance IMO.

Operating temp on a TC is 260-280 degrees... That is at the Cylinder head.... After 280 it starts EITMS Step 1...

Oil temp should not exceed 250 for conventional... Syn can go up well past 350....
