Well, I want to change the oil and I don't know what type of key is that of the Renault Megane plug, have they told me that it is block, but what is the measure?
You have to make a new key for this uses a 3/8 quadratic increase, reduce it until it squares the hole. You must use the tool material of any brand but is tempered. It is lowered with an emery. Obly if this piece exists but it is special and is very expensive.
Thank you very much, well I went to buy the key, and they told me that it was a square of 8 square, what was said, the oil, oil filter and air filter is changed
