Got my oil and filter changed today at 3000 miles (switched to Shell Helix Ultra 5W-40 in case anyones interested!) - picked up the oil and filter myself and got a local independent garage to change them for the very reasonable price of 10 quid + VAT.
However, a mate has since suggested that I mightve invalidated the warranty by using non-Renault parts / labour. Is this right?!
Have searched for other posts but the most similar I could see was on brake pads - the conclusion was that the pads are a consumable and thus could be replaced by anyone without affecting warranty (as with tyres). Do people think the same would apply with an oil filter.....?
