Hey all,

Checked my service history the other day and couldn't see any history of the plugs being changed since a service when it was on 35k, its now on 115k! Bought 4 genuine plugs in Renault boxs from a powerseller on eBay and started changing them. Easy job and old ones wernt too bad but plugs 1 and 2 were oily, so were the coilpacks. There was no oil on the threads or tips though, could it have been that oil was spilled when topping up the engine?
