Hey people, got a manual 08 zd30 with 180k on it. Has egr block, 3 inch turbo back exhaust, catch can, dawes/needle set to 17psi and a k and n filter. Saturday i was about to head on a 400k drive when I noticed the oil light come on. Checked oil which is still full and a nice golden colour (I run penrite 20w50). Anyway I did the drive light stayed on the whole time. When car turned off when I start it again the oil light usually comes on within a minute, however a few times since it happened I have driven up to 50ks without it coming on once, have now done 600ks since i noticed it. Car is still full of oil and isn't making any funny noises, guessing it would just be a sensor issue but any opinions more than welcome, my thoughts are if it was low oil pressure it would have damaged it by now. Nearly due for an oil change but that shouldn't make a difference.
