That's within spec according to the manual, but I have never seen temp that high, in any weather, in any of my 993's. Did you feel the vent in front of passenger front tire to see if the oil cooler fan was functioning?
No I didn't. It seems high to me. This is my first 993 so I don't have a reference point but my '89 3.2 never went that high on a 75 degree day.
I'll check the it as you recommended tomorrow.
mine doesn't get that high in those conditions either.
However, how long was it idling before you took that pic? If I idle mine for very long it can jump that high pretty quick even a couple of minutes. But like P daddy says, you should notice the fan.
You may also want to ensure that nothing is blocking the oil cooler. Leaves, dirt, bugs. They all accumulate in the oil radiator and should be cleaned out.
At that 9 o'clock position, the oil cooler fan on my car would be running at high speed.
Too high under those conditions. Check that your fan is kicking in at the appropriate point. (Low and High speeds) If not, its the relay behind the front bumper. Replace it. If it's ok, check your oil level, at temp, on level ground, with the dipstick. If it's midway between the twisted part, then I'm stumped. If it's low, put some oil in it. O'Reilly's has Mobil 1 on sale right now for 5.99 a quart.
It looks like your oil temp is about where the low speed fan should kick in - even if the fan is working correctly it shouldn't get that high on a 75 degree day. As BesideTheBox suggested, your oil cooler may be blocked. Another possibility is a problem with your thermostat (but I am a 993 newbie and will defer to other RLers with more experience with oil system issues)
This appears to be high and there is definitely a reason for this. I get temperatures like this in a 90 degree+ day with lot of red lights.
Assuming that the gauge is working properly, I would check first if the thermostat opens the flow to the front oil cooler. You can easily notice it due to the heat that is dissipated at the rocker panel on the passenger side. This is where the lines are routed to the cooler. The p-car.com instructions have everything that you need to trouble shoot this.
For those conditions (air temp and highway driving) that's a high temp. I would expect it to be at the 3rd hash or a neddles width below the 3rd hash mark.
That is the highest my oil temp guage ever goes to, it is the right temp to check the oil level accurately but may be a bit high for the type of use you described.
One of the first DIY's I did on my car was a manual over ride switch for the fan, now when ever I am in traffic I flick the switch and she stays cool.
I agree that does seem high. When I first purchased my car I had to block part of my oil cooler to get to that temp to check the fan function. If the fan checks OK you may want to check the oil cooler thermostat. I recommend installing the fan switch override also.
