Evening chaps!
I serviced my mk4 1.8T around March time, this included replacing the oil filter and oil completely. Since then I've done 4/5k in the car, and expect to have done about 6k by March next year. Having regularly checked the oil (which I filled to the full line of the dipstick) I've noticed the car has used absolutely no oil, well none so as could be detected from a drop on the dip stick level. It isn't even that dirty looking either.
Question is, is it worth replacing ever 12 months, or should I just keep the same oil for longer, say 18 months or whatever? Or given I do half the average mileage a year, would every 2 years be a stupid suggestion?
Cheers
