Let me see...
Changed engine oil and filter on car 1.
Removed LED tail lights and replaced with stock 10W bulbs - fixes 'Check' 'Brake Lights' issue.
Fixed high level brake light.
Replaced fuel filter to see if it sorts sluggish acceleration - not tested yet, but all sorts of yuck came out of the filter.
Changed engine oil and filter on car 2.
Fixed ABS / Speed sensor issue on same car. (Actually - I'm not sure how I fixed this. It was there, I jacked it up, and now it's gone. )
Changed engine oil and filter on car 3.
Tomorrow I see if Repco in Hamilton still have an oil disposal bin...
