The colour of the oil was not too bad. I think it could go for another 1000kms. However, I believe it is no harm to change oil frequently. For the oil filter, I put a few amount engine oil on the new o-ring.
Just watched to refresh my memory. Pretty good video, simple and straightforward. Guess I'm a little more anal, I noticed you didn't change the crushwasher gasket on the drain plug..probably not a big deal. When I put my filter back I torqued to spec. 8 ft. lbs. On the filter drain and 18 lbs. on the filter. Guess if you do enough of them you can go by feel .
