What type of oil is in the car? If a good quality 'Fully Synthetic' then I'd be tempted to leave it longer, if some other cheap mineral oil, then I'd change it and the filter and replace it with Fully Synthetic and a new filter, what's it going to cost you, about £30?......Well I've only done 2000 miles this year, pottering around town.
Do you still think its worth doing this after 12mo.
Don't want to waste money but also want to keep the engine in good condition - its a great car.
Well said!look at it this way,
oil and filters are cheap, engine internals such as timing chains etc are not.
