Just changed the oil on the Mazda 2 today. Thought I'd use my impact wrench as the sump plug is slightly awkward to get to. Didn't remember it had such a short thread. It came right out, luckily had an old towel down and shoved a tray under really quickly. Still got some oil on the tarmac drive. Tried some cat litter (cheap clay type), then soluble degreaser mixed with hot water and washing-up liquid, then hosed it down. Not sure what will look like when dry. First time tried cat litter. Never been able to find something that gets it fully off tarmac. Fingers crossed. Won't be using the impact wrench again, not enough access to use it with old cat litter tray underneath.
