I apologise, this is probably the millionth time this has been asked.
I have been abusing my car and feeding it s*** oil for ages now. It had treated me quite well the last few weeks so I thought I would treat it a festive oil change and new plugs. Went to halfords and looked at some mobil new life.. 45 quid just for 5L so would be 70quid just on oil!! And thats doing it myself?
Am I looking in the wrong place or at the wrong oil?
Car is on 110k and gets the driven properly.
Anywhere online I can buy good, cheap oil.. maybe even sparkplugs? Heard champion are the bees knees.
