This morning I noticed something slightly peculiar with my oil temperature reading in the Maxidot. I started the car from cold and drove about 5 minutes. The oil temperature did not display a temperature during this trip (AFAIK this is normal until the oil reaches a certain temperature). I then switched the car off to drop off the young' un at daycare which took all of 2 minutes. When turning the key in the ignition (but before starting the car), the Maxidot displayed an oil temperature of 64oC. As soon as I started the car, however, the temperature displayed changed to 50oC or thereabout, which then continued to climb normally.

If I remember correctly, when the engine is on throughout the process of warming up, the oil temperature starts to register when it has reached more than 60oC or so, so I can't help but wonder (a) why I got a reading of 64 while the oil temp was -as far as I can assume- less than that, and ( b ) how come a temperature of 50something did display once the car was re-started.

I do the same trip almost daily, so will keep an eye out for more specific details if it happens again.

Hello GCP

To my opinion you noticed this for the first time,and it happens always,and is quite normal .Dont forget it is only a five minute trip you took, and the oil temp didnt have time to stabilise and reach its working temperature.If the oil temperature reads ok,reaches normal working temperature and stays between 90 and 110 degrees C after a few kms drive with the water temp on 90C , you have nothing to worry about.Read what the plumber has to say on this thread http://www.briskoda.net/forums/topic/266672-oil-temperature/

Even though he lives in a much colder climate than ours.

Presumably a form of heat soak?

This is why manufacturers don't like us to have monitoring gauges for us to worry about.

I'm with Nick on this, you have been running the car and then stopped it, the top of the engine will be hotter than the bottom because that is where the heat of combustion is produced. You have turned the car off and that heat has transferred into the oil where the temp sensor is. You restarted the car and the oil got circulated and mixed in with the rest of the oil in the sump so the temp dropped and then started to climb normally as things got going. I'd say quite normal and nothing to worry about.

Agree, this normal. Oil temp will rise when engine is stopped or slow a little after a fast run before dropping back.

Heat soak does indeed sound like the most plausible explanation, hadn't thought of that. Interesting what one finds out by monitoring the car's vitals - and by asking a knowledgeable bunch like the good people on Briskoda!

I think I can speak for everyone (well perhaps almost!) when I say that we are always glad to help another who has seen the light and become a Briskodian

And it starts registering at 50 degrees.
