A few tips to get the best effect:
1, Drain oil when very HOT & give it at least 10 mins. to fully drain thus ensuring max. contaminate removal in the quickest time.
2, Pour 1/2 L of fresh oil into the sump so as to flush out the remaining oil that will still be lying about, again allowing it to fully drain. You'll be amazed how much more dirty oil comes out!
3, Prime new filter with enough oil to at least soak the element (reduces time required for new oil to fully circulate).
4, Fit a bonded type washer to the drain plug, it will last indefinitely & seal perfectly with little more than hand tightness.
There's nothing like a good oil change to make a car (& it's owner!) run better LOL, & there's also the satisfaction of a job well done.
