I am breaking in my new 103 build, running normal break in oil, so no Amsoil yet. Outside temp has been 80 degrees on average, I run the HD oil cooler, and I put my digital dipstick back in for a while, I have seen the oil temp running 227 degrees, is this high, or normal operating temp??

Thanks,

 

Same set up 103 and hd oil cooler and amsoil synth in a hot day 230 seem normal i have the McEwan fairing gauge with the sender in the oil pan

 

That is good to here, tells me I am doing ok, even with running up to 3500rpms and back down a lot right now too.

 

my 03 rg runs about 230 to 250 on 80+ deg days (95 cid se heads and no oil cooler yet)

 

I have a 2008 Ultra 103, 255 cams, SE hi-flow heads, SERT, HD Oil Cooler and recently dyno'd. On my recent trip to Key West I hit 101 temps in Georgia and my oil temp was just a bit over 250 running at 75 mph on the interstate with lowers off. I was using syn3. I just switched over to amsoil and went to the JAGG 10 row oil cooler. Havent had the opportunity to see what kind of difference it would make (if any) since the temps have been in the mid 80s here in NJ. If this doesn't lower the temps significantly, I will go to the BaKer +1 oil pan this winter.

 

Been 100deg last few days and my McEwan reads 230 when running highway speeds

 

Mine, to. We've had 100+ six days in a row. My 103" has been running 230 on the freeway but has gotten as high as 260F on surface streets and in stop and go traffic.

 

I would like to hear how you make out with what you have changed.
