guys my oil temp is normally running around 88-90 degrees C (190F) but is now running at around 90-95DegreesC (194-203F). Now air temp here has increased a few degrees over the last week and the other day I changed from 10w40 to 15w50 fully synthetic oil.
Oil pressure and water temps are withing normal range.


Thanks for any help you can offer.

 

190F is rather hot, i sit at about 180 stop and go and about 150 on the freeway...running a mugen t-stat and full size fluidyne radiator..lowered coolant temp will result in lower oil temps imo..

 

Your oil temps seem to be in normal range and I wouldn't worry about it. You want to get the oil up to about 200 degrees F to help boil any moisture out of it, which can lead to sludge.

 

agreed oil temp is fine. Normal is usually in the 200-210* range. Just to give you an idea my oil temp's here in Arizona summer time will hit 245-250* on the freeway with moble 0w40 syn. Your temps are fine
