you lot have to be joking, you really check your oil? Thats why you service the car (but I will make a point of checking the car now).
I'm having trouble telling if this is 'for real' or not. You service a car to change the oil, you check the oil level between services. I check mine every 2 weeks or so. I also check all other fluids at the same time.
I simply can not believe that the oil level can fall under the minimum level after 4k miles, I will stick another litre in tomorrow but I hope it does not keep doing this.
New cars will use more oil. But a litre in 4k isn't a lot anyway.
