The salesman at VW said that for the 1st 1k miles the car will run at 90% power. Does anyone know about this?

I got a new 2008 VW Rabbit. The salesman said that the car will run at 90% power for the first 1000 miles, after that, the car will run at 100%. Can someone explain why and what the heck this feature is all about.

Oh, what it means is that, while some cars require you to run over a certain rev limit, it won't fully apply itself until the engine has fully "worn in". This usually takes 500 to 1000 miles.

We call this running in for 1000miles.


The manufacturers knows that some people will want to drive at the full speed.


This high revs will cause engines to seize/cause damages at times.when the new this can happen.


u must give time for slow wear/tear on metals.


To avoid all this hassle,the accelertor paddle is fitted with a stopper bolt to limit your acceleration.


When you go for the 1000 miles service,they will agjust and give u maximum acceleration.
Reply:BS to the "stopper bolt" In my 20+ yearfixing I have NEVER seen that %26amp; The salesman is a retard. You should take it easy on the car for the first 500 miles to allow for break in. Definition of Break in.....The first few hundred miles of a new engine's life have a major impact on how strongly that engine will perform, how much oil it will consume and how long it will last. The main purpose of break-in is to seat the compression rings to the cylinder walls. We are talking about the physical mating of the engine's piston rings to it's corresponding cylinder wall. That is, we want to physically wear the new piston rings into the cylinder wall until a compatible seal between the two is achieved.


Proper engine break in will produce an engine that achieves maximum power output with the least amount of oil consumption due to the fact that the piston rings have seated properly to the cylinder wall. When the piston rings are broken in or seated, they do not allow combustion gases to escape the combustion chamber past the piston rings into the crankcase section of the engine. This lack of "blow-by" keeps your engine running cleaner and cooler by preventing hot combustion gases and by-products from entering the crankcase section of the engine. Excessive "blow-by" will cause the crankcase section of the engine to become pressurized and contaminated with combustion gases, which in turn will force normal oil vapors out of the engine's breather, causing the engine to consume excessive amounts of oil.


In addition to sealing combustion gases in the combustion chamber, piston rings must also manage the amount of oil present on the cylinder walls for lubrication. If the rings do not seat properly, they cannot perform this function and will allow excessive amounts of oil to accumulate on the cylinder wall surfaces. This oil is burned each and every time the cylinder fires. The burning of this oil, coupled with "blow-by" induced engine breathing, are reasons that an engine that hasn't been broken in will consume more than its share of oil. PS your first service isn't due until 5000 miles. Happy driving.
