I'll be taking ownership of a new 2016 STI in a week or so and I was wondering about running it in. From what I have read it's best to stay below 4,000rpm for the first 1,000 miles (1,600 km) and to avoid stressing the engine too much by being in too high a gear.
I'll be using it as a daily driver for a couple of weeks before taking a trip back to the UK to visit family and friends. This will hopefully knock most of the miles/kilometers off in a short time - it's about 360miles from home to the UK, and is 4hrs motorway to Calais/Dunkirk, and then a couple more from Dover.
From the US owners manual, as I can't find a UK one anywhere online it says:
The performance and long life of your vehicle are dependent on how you handle and care for your vehicle while it is new. Follow these instructions during the first 1,000 miles (1,600 km):
. Do not race the engine. And do not allow engine speed to exceed 4,000 rpm
except in an emergency.
. Do not drive at one constant engine or vehicle speed for a long time, either fast or slow.
. Avoid starting suddenly and rapid acceleration, except in an emergency.
. Avoid hard braking, except in an emergency
The second one concerns me as that's more or less what will happen on my drive back to the UK. I currently own a 2003 WRX and this is exactly the same trip I made when I got that from new, I had it a few days then drove it to the UK but the above recommendations were not known to me then - 13yrs & 86,000km later I don't think it did it any harm.
Any advice, or am I worrying too much about it and just do the trip normally avoiding any harsh driving?
