They're just covering their backsides incase anything goes wrong, just wring it's neck from the moment you get in and you'll be fine, be honest are you really worried at 3 years old when buying your next one and trading this in?
I've only ever had new company cars ( my own cars were always used), but can't help myself but to take it gently when they are new. I'm at 4000 miles on my current car and just starting to open it up a bit now and then, though it's under 1500 rpm at 70 anyway. The 'first service' isn't until about 12k, so the days of an oil change after the first 500 miles are long gone I guess, but I've rebuilt a few engines over the years, so I can't help having a bit of mechanical sympathy with a new car.
Nowadays if you exceed the manual recommendation at 1 mile or 1,499 wouldn’t they see that if they want to look at the detail in the electronic logs if they actually enforce a rule to refuse warranty if you have not waited until 1500 miles?
If that enforcement exists then it won’t matter if you wait until 500 miles and you might as well drive it as you want from day one
I suspect they won’t be clear about enforcement of the rule/recommendation in the manual, since whilst we aren’t sure and some say they dealt with warranty issues with the engine despite exceeding the revs, and some say they didn’t and they are heading to court, the majority will comply to avoid the lottery.
If they gave a clear rule that it was to the rev and mile, there would be mass outrage and they would have to defend the postion leading to it being removed.
I’m sure they prefer to say as always it is a recommendation and they will consider each case as it comes up. Kind of reserve the right to refuse warranty repair where there is evidence, in their opinion, that the revs and miles were/maybe were the main/partial/possible cause of the issue they have forensically observed without your involvement
Anyway enjoy it however you drive it isn’t eb next 1,500 miles
