Guys my oil level warning light comes on whenever the revs drop in the car. I would start it up and go for a drive, after a while if I stop at lights or in traffic the light comes on. Even if I drop gears while driving and the revs drop below 2000rpm the light will flicker. Any ideas, oil level is spot on. Car is a 2001 1.6 bravo.
Thanks

Dodgy pressure switch or low pump pressure.... when was the oil last changed?

Check the oil level?

Oh oil level ok.. um.. wrong grade oil? Worn oil pump?

if the oil is too thin (such as a 5w30) then it can do this. do you know which grade of oil has been used?

pressure swithc faults are not uncomon, and it is easily replaced, so i would try a scrapyard replacement if the correct oil has been used.

if replacing the pressure switch does not help then you have oil circulation problems. it can be caused by a blocked strainer on the pickup pipe in the sump. checking and cleaning means dropping the sump.

worse case is a warn bottom end or worn oil rings. but try all of the above first. hopfully its somthing silly
