Ok ive done an oil change on the car including filter and sump washer.
I also flushed the engine an left it to drip all out for a while aswell.
But how much does the engine need to refil? How many liters of oil?
I replaced mine as the little bit of rubber that goes on the inside of the washer came off an it looked to have a nic in it. And for the sake of a quid its not worth moaning about.I've never changed a sump plug washer on mine yet , i always reuse the old one without any problems .
