High Oil Temps
I was watching my engine oil temp yesterday. Then started asking other guys with us what their temps were and was surprised by the variation in temps.
85*f temps. Bikes were all twin cam baggers 96ci-117ci. All the bikes are tuned and one way or another modified. 230* oil temp to 290* oil temps were seen. Every bike was heavily loaded running 45-90 mph roads 2 up.
Dino and synthetic oils were both in use.
I thought I would take a poll and see at what oil temperature you get nervous and at what oil temperature you pull over...
Please mention whether you are using Dino or synthetic...
Just seeing what everyone is comfortable with! :teeth:
I will go first! :
I am running dino 60wt engine oil and I am comfortable with the high of 230* I have seen.
I am thinking pulling over or changing riding style to lower temps at 285* would be prudent if I ever saw that temperature. I am not worried about the oil as much as head temps(valve seats) and bearing damage.
Before the heat of summer hits the wards fan and oil cooler fans will get mounted and set to turn on at 210* oil temp. Not for everyone but that is what I am comfortable with.
I have had an unbelievable amount of responses to this question on other forums and talking to buddies. I have now spoke to 3 different engineers about oil breakdown...
Universally with Dino oil they are nervous above a sustained 285* and on most synthetics 315* seems to be the cringe point.
