when changing oil in any car there are a few simple steps that can make the whole job a lot easier
#1 when unscrewing the sump bolt, do it with a spanner or whatever until its loose enough to loosen by hand and then do it by hand but while unscrewing it push it towards the hole so oil doesnt leak while unscrewing it out and when you can feel its out quickly take it out and hold it over the pan or whatever your using.
#2 dont change oil while its hot, the oil will get hot after the car has been running for a while, it will burn very bad and it wont stop burning after its washed off, it'll still burn. if it really needs doing, loosen it untill its nearly out with a spanner and then take it the rest of the way by pliers.
#3 when changing the oil filter which should be changed with the oil, loosen it and let the oil just run down the side and off into the pan and dont take it all off until its stopped leaking or just dripping slowly because a gush of oil could come out.
hope that helped, and remember, dont take your car to the mechanics to get an oil change, do it yourself!
hope you enjoyed my spellign mistakes lol
