I just bought a relatively high performance xr, built by cv. due to my ignorance, the oil was a bit low, and ive driven it probably 1000km (sydney to brisbane) with low oil, and the light came on and off a few times before I noticed and checked and found it was pretty dry. ive topped it up and it took about 2.5-3L to read full on the dipstick, so it would still have had 4-5 litres in it still.... what are peoples opinions of if ive done any damage, and how I would tell, and more importantly what I should do from here....I would be gutted if I caused the car any damage...its on a very mild tune and 12 pound. its pushing through a turbo 400 gearbox if that makes any difference...
