My service is now due (I like to do it every 12 months), but I have decided to do very little this time round, as it is only 9,000 miles since I last serviced the car. I changed the air filter last year and it was clean. The pollen filter looks fine this year (there wasn't one last year!) and the car was given a check over prior to its MOT last month.
The gearbox was rebuilt in January so I know the transmission fluid is okay, and I normally check the coolant SG just before the start of the winter.
I do have engine oil and a filter on hand, and my son-in-law will change that for me as soon as he returns from holiday. I change the engine oil every 12 months, even if I have only done a couple of thousand miles.
Owners with newish cars will probably throw their hands up in horror at my service plans, but the car is 12 years old, has done 105,000 miles, and will probably succumb to rust before it dies mechanically. I check things like tyres, wipers, screenwash fluid myself (time was when I did all my own servicing and repair) and I am quite confident the car will soldier on.
