New car speed limit

[sh_Callum]

Comrades, I have been driving for more than 20 years, changed quite a few cars. Whenever I received my new car, I will limit my speed to 110km/h or below for 1,000km mileage before I go for maximum speed on highway. Just wanted to get your opinion, is it necessary to do that ? Also, the 1st 1,000km, I normally replaced the motor oil and filter due to virgin engine which expects to be more wear and tear. Thanks.

It's for good measure but not mandatory with new generation engines

IMHO....regardless of what's written ie about new gen engine not needing any breaking in,the best is stilll to ref to the owner's manual.....

This is what I found it from AAA, just for sharing purpose : http://www.theaa.ie/AA/AA-Membership/Members-Advice/Running-in-a-new-car.aspx A car’s first thousand miles Motorists should begin with gentle town driving so the car’s major components can bed in. New tyres have a thin oily coating, until this wears off, vehicle handling will feel different, especially when driving in wet weather. Motorists should avoid harsh acceleration and heavy braking when driving a new car Motorists driving a new diesel car shouldn’t let the vehicle’s engine speed exceed 3000 rpm however should make sure the revs regularly reach this limit Motorists driving a new petrol engine should stick to a 3000 rpm limit for the first 500-600 miles and then increase the upper limit to around 4000 rpm. Again, revs should regularly reach this limit. Motorists driving a new vehicle should avoid labouring the car’s engine – by changing up too early for example Motorists driving a new vehicle should check the car’s oil and coolant levels (Click here to view our ‘AA Rescue Guide to checking your coolant’) at least once a week as they don't know how much oil it will use. Motorists driving a new car should note that oil consumption can be high for the first 6000 miles or so but should slow, particularly if the car's been treated gently in the early days. After the first 1000 miles, motorists can gradually use more of the car's performance.

As stated in the "Break-in period" section of the manual:

Up to 1,200 miles / 2,000
Do not exceed the maximum engine and road speed:
- For gasoline engine 4,500 rpm and 100 mph/160 km/h
- For diesel engine 3,500 rpm and 93 mph/150 km/h

Avoid full load or kickdown under all circumstances.
