is my oil 2hot?
mrvett:
hi all, might have a bit of a problem if any1 can help..latey my 87 oil temp has been gettin round the 102-104degrees celcus mark..is that ok?
i drove my car round melbourne this morn and it was fairly cool and drizzling a little, but i still got to 102' celcus..was definatly not driving hard!! is this temp ok? how hot can i go b4 doing any damage?
also do our c4's have factory oil coolers?
Shane Finn:
That is about perfect according to most people with opinions.
It it just hot enough (>100c) to boil off any water condensates that would collect when the engine is cooling. My C5 cruises at around 105c on the highway.
How much hotter you would be happy to go is dependent on whether it is a natural or synthetic oil. The problem with higher temperature is more that the oil life shortens rather that it is ceases to be a good lubricant at that temperature. Synthetics can both sustain higher temperatures and last longer at temperature than do natural oils.
I often see 135c on the track but back off when any higher till the synthetic oil I use (Mobil One 15w50) cools down. But then I change it regularly (often twice a year) depending on how much track time I see.
I can't help with whether or not you have a cooler in a C4. Others will chime in I am sure.

Some do.
Option KC4 on the label under console lid or part of the Z51 suspension package.
Check for a black housing between the oil filter and block with 2 water lines out of it.One hose goes to block and other to front of engine.
