Hi guys,
While I wait my new car I was watching this guys and his videos
Engineering Explained on youtube, sorry no links for 15posts

He seems pretty reliable from what I see.

What do you believe in about braking-in the engine, meaning SEAT engines, in my case 1.8T Petrol

Never mind, just find the official dociment that state the following:
A new vehicle should be run in over a distance
of 1500 km (1000 miles). For the first
1,000 km the engine speed should not exceed
2/3 of the maximum permissible engine
speed. In doing so, do not accelerate at full
throttle and do not drive with a trailer! From
1000 to 1500 km (600 to 1000 miles) you
can gradually increase the engine rpm and
road speed.
During its first few hours of running, the internal
friction in the engine is greater than
later on when all the moving parts have bedded
down.

Do NOT pay any attention to those advocating "hard" break ins. Race teams use hard break ins because they do not have the time to follow manufacturers specs, and they are not interested in long term durability because they rebuild engines so often.
Manufacturers recommendations are there to maximise engine performance and durability for it's intended lifespan.
Some of the nonsense on the interweb makes me shudder.
Google some of the break in requirements for large displacement piston aero engines for strict break in protocols.

Just drive it gently for the first 1k miles, and try (no matter how difficult to resist) not to go more than 3.5k rpm, and no pedal to the floor.

Put some good petrol too, maybe Shell or Esso's finest (not sure where you're based or which fuel stations near you).

After 1k, enjoy the full 180PS!

Oh, another thing...the car is likely to arrive with astronomical PSI on the tyres (due to it being on trailer). You may want to lower it, if you find the ride is too harsh.

Mine came with 40/37 (highest recommended is 38/35 and comfort recommended was 33/30).
