Car has always been on a longlife service regime with its next 'scheduled' service in a few weeks.

However, it had an 'un-scheduled' oil service in March 2014.

Checked the oil a few months afterwards and had to top it up slightly and haven't checked since then.

However, when I checked this morning, it was fairly low and it took about a litre to top it up.

Oil being used is VW Approved 5w-30.

On the face of it, does this point to an underlying issue with the car or can it be put down to age/mileage of the vehicle?

Would switching to an annual service regime and VW approved 5w-40 oil improve the situation?

Car appears to be running fine with no signs of any oil leaks.


Car: VW Golf GTi 1.8T
Type: Petrol
Year: 2001
Miles: 105k
Use: Mainly daily commute of about 30miles.
Annual mileage: 12k (max).

TBH, I probably got sucked in by the marketing of the long life servicing regime but lesson learned.

Car was serviced last weekend and reset to an annual service and is now using VW Approved 5w-40 oil.

However, the engine management light has now come on and, after speaking to my mechanic, he has suggested that this is probably due to the sensor in the sump detecting the thicker oil.

Hope to get him to look at it this weekend but wondered what the solution would be.

Surely, by resetting the service indicator to an annual service, the car/computer would know this will mean use of a thicker grade of oil.
