First 15/20 minutes

Is it correct that you should drive below 3000revs for the first 15/20 minutes? Been told you can dammage the engine if you drive above this. Problem is that I am a bit impatient!

Bloody hell! Do you really have to ask?

In short yes, you should let all the fluids warm up to full operating temperatures, before giving it wellie!

You're looking for the idle oil pressure to drop to its warm value, in my case this is about 40 psi, but no doubt varies from car to car. How it takes for the oil to warm up and the pressure to drop will vary too.

when i had my m3 it had a oil temp gauge, it takes a suprisingly long time for the oil to get upto the correct temp which was about 15 mins, i think alot of people look at the water temp and think if the waters hot then its ok to start giving it a bit right foot. If your worried iam sure you can buy and after market oil temp gauge and put it in (dont think any cerbs had this from the factory)

You will very quickly stuff the engine and create premature wear if you rev from 'cold'.
My approach - first 4 miles max 2.5K
next 4 miles = max 3K
then go to about 4.5K and then when car is very warm I go higher.

I used to use time/miles travelled as a warm up guide, but after fitting an oil temp gauge its suprising how long it can take for the oil to get up to temp. In the winter it never does, another good reason not to drive hard in february

Alternatively if you fit an oil thermostat you'll find that the oil heats up much quicker, mine tends to reach 50-60° within the first 10 minutes, with the temp sensor fitted into the filter housing

all sounds good but the delivery driver has probably done more damage when he took it off his transporter
have you actually been to see a new car built say fords etc they are screamed everywhere
then we buy them and run them in lol

It's not a mass produced Ford though is it !
