Here are some in a file that I keep. Haven't done it on mine yet. Elsewhere, I posted about using an extractor. Several have done so on the 3. Think I'll probably do the bottom drain for the 1st one and then do oil extraction. Don't save that much on a 3 because Mazda wrongly placed the oil filter underneath. The oil filter and drain plug seem right side by side through the small hatch that you remove. I've gotten spoiled over the last 32 years in being able to change oil and filers from the top on our German cars.
