hey all,
my oil light always comes on everytime i come to a stop after driving 80kmph+ (after freeway driving), i need to keep the revs up a little for it to
go away. if i'm sticking to
Have you check the oil level when the car is flat and has been sitting fora few minutes ??? may need topping up
how hot is it getting???
Slightly low idle speed? Make sure it's set to the upper end of the normal range, eg. ~900 rpm for late 1600. Idle can drop when eng gets very hot.
oil level is full.
its not getting too hot
low idle speed when it's hot...maybe
Is this bad for my engine in any way? will check my idle's next service
Sometimes my Beetle's oil light comes on, usually if I stop quite quickly.... the revs drop and oil light flickers, I think it's to do with oil
pressure dropping.

Could thickness of oil contribute?
i am currently feeding her straight 30
Check the oil pressure with a manual gauge that screws into the oil light position,
Sounds like you have low oil pressure, not good, is it a dual relief case?
I would also change the oil to a 20-50 multigrade oil, but thats just me.

dual relief case?? not sure what that is.
i am usuing straight 30 because that is what the person that built my 1916 engine told me to use it (had it built
The lights can come on at various pressures. eg. "2 - 6.5 psi" for late beetle, but maybe it varies more than this, depending on the individual
pressure switch.
Is it possible that "crud" can build up behind the switch? Could carefully remove & replace it to check. (Should be tapered thread - don't use
thread sealant/teflon tape!)
Could try one higher notch up the visc. scale, eg. if you like mono 30, try mono 40 - will be fine in Sydney. If you can find a good mongrade still.
Mono 30 is most "like" 20W-40, and mono 40 is most "like" 25W-50 in composition, if want to try a multigrade.
Could be sensor. Bu tif you consult an original VW manual it says that the oil light comin on after a driving at speed, or something like that, is
normal. My S used to do it, But that was usually after going @ 110km/h+ in hills for over an hour. Use multigrade oil. Please. Listen to the
others.
Also, long shot. Smell your oil please. I'm a little worried your fuel pump is leaking or the fuel cutoff solenoid isn't all it could be.
