Hi All,

I had installed an engine oil temperature gauge on my TJ (using a filter sandwich plate). Results are as under:

* city driving at around 50 kms/hr - temp takes about 6-8 kms to rise above 175F and then stays at 200F

* highway driving early morning at 100 kms/hr - temp takes about 15-20 kms to rise above 175F and then stays at 200F

* highway driving for a while (50+ kms) during the day followed by city driving (without stopping for cool down) in heavy traffic for 10 minutes - temp almost shot up to 215/220F. This came down a little as I started driving at city speed in better traffic.

In all above conditions, the engine coolant gauge (factory) stayed at 95C (about 195/200F). Coolant gets hotter quicker, but stays the same (so no cooling problems). Also, its winter in NZ.

Has anybody else got any insight into engine oil temp norms. Would this be normal behaviour. I have not had a chance to try it out in off-road conditions yet.

Thanks
