Yeah it's 10%, so over 44k and it can void your warranty

thats why i asked , it could just go on and on , i am doing 20k a year , my 30k service was done 6 months a go at 29,679,miles car is 19 months oldive never heard of this 10% rule either, but even if it is accepted it will be 10% of the interval, not 10% of the total mileage.
so on a 10,000 mile interval you can go over by 1,000 miles. which to me sounds better.
what happens next time.. as it appears that if you go 10% over each time you can save 1 in 10 services?
ie service at: 11k 22k 33k 44k 55k 66k 77k 88k 99k 110k.. you have then done 110k miles with only 10 services..
you could also miss out servicing altogether for some components if you go over intervals significantly as they could do a 50k service when a 40k is due which may have specific service items.
if you got serviced at 44k rather than 40k and was serviced at 30k previously this is a massive 40% increase in mileage not 10%.
We need to know what mileage /age you got the 30k done.
I was 3500 miles over last time (dont ask) and the dealer didnt blink. Just did my warrenty work![]()
its in the handbook, and Im sure its longer than a month and more than 1000 miles

checked my service book and handhbook nothing in there![]()
... or maybe not cos the service interval is 10,000 miles and 10% of that is 1,000 so it's the same rule.Whenever I've asked I've been told it's a thousand miles, never heard of this 10% rule before, I guess each one is different.

Not sure I understand the question...But what about on my 20 and 30k services![]()
