I ride in 95+ weather all the time with gridlock traffic to boot. My CHT would reach 280-320 easy on jam, after FCS from WPW my CHT dropped drastically to 250 when moving and even lower when idling on jam, when it's not too hot even as low as 217 idling....should I be concerned about oil temp at all with CHT that low?? My oil is SAE60 full syn Amsoil, run SAE 60 because where I live temp never ever below 80 with 90-105 most often than not.

I have 4" spal fan lying unused originally wanted to DIY oil cooler fan, but after seeing my CHT dropped that much I am wondering if this is still needed. Folks said oil temp will always be cooler than CHT. I actually started to worry that my oil temp will not get hot enough to burn all that crap.

 

I wouldn't worry about it, the oil temps are getting hot enough.

I have a FCS and ride in the Tx heat with Amsoil 20-50. I also have sent in my oil for an analysis several times and there were no issues with contamination from lack of proper operating temps.

Not sure what type of bike you have but I would install an oil temp gauge to monitor the temps.
