do I need an oil cooler?
I've got my cabrio back on the road after a few years and using it a bit to get used to all the mk1 quirks again
I've got Audi guages and am noticing oil temps getting up to 130 when thrashing it a bit (~5k rpm for a while). it cools down when I ease off a bit, back to 115-120ish.
so is that normal? the car has an ABF fitted using a mk2 16v box on 13" wheels, so need to rev a little more than usual for motorway speeds.
any thoughts?
the oil has been in there a while (5 years) but not done many miles due to being off the road.
cheers guys!

Does your ABF have the oil-water cooler, and if so what size radiator does your car have?
Your oil temperatures are far from normal. Have you checked the gauges are reading true?

give me a clue what the oil-water cooler looks like?
I'll try to remember to get a pic of the bay so it's easier to see what's in there. think it's a normal mk1 rad, the car was originally a 1.8 carb and I think the original rad is in there. otherwise it's from a GTI (if there's a difference?)
how should I check the guage accuracy?
cheers!

There's at least 5 different types of radiator on the mk1 - kinda need more info on that one.
Unsure best way to check it but matching the sender to the gauge is essential. Which sender is in the engine etc.

will try to get a number off the rad…

the oil-water cooler is a metal square thing that the filter goes into, about 3" square? if so, check

might have been a bit hasty here - it's the pressure sender that's from the Audi, the temp sender is on the sump plug, think I got that from Big Boys Toys.trisGTI said
the sender is from an Audi (e80 I think).

Basically, if its shooting up in a couple of mins to 120, I'd say faulty gauge rather than overheating oil.
You can sense if an engine's hot or normal when you open the bonnet after a run, but again I can't really type that into an internet.
Getting all the gauges working properly can be thought of as a task within "stage 0" of tuning.

the guage doesn't shoot up, just rises fairly slowly as the car warms up. the engine feels hot after a good drive.
I'll check on the drive home later exactly where it settles during "normal" driving.
I'll have a go at mending the water temp sensor, as you say that could provide a good clue.
will also change the oil.
what sort of oil temps would you expect to see, on average? the coolant isn't boiling or anything like that.

it is settled about here:
it's not really very well marked, does the line between 60 and 130 mean 90c?
