They're a known fault regardless of who owns the car though. As long as you're happy though. What was the overall cost?
 
I wait for idle to drop to about 800-900 rpm so I know all the oil has move round the engine! If this has already been said sorry for wasting time lol

It would be better to drive off and be gentle with the throttle than leave it standing, due to the oil pressure.

My idle is only a little over 900 straight after starting? :?
 
The new RS has a different quoted mpg figures, not sure about co2 emissions. I can only assume that as nothing mechanical has changed, it's a mapping difference. Which could explain the variance in idle when cold

At idle theres very litle fuel being burned, so the heating up of the engine will be relatively slow. Also, theres less mechanical forces acting on the oil which will therefore take longer to heat up from it being sibject to friction forces etc. Also, the oil won't pick up as much heat from the top end of the engine as thats not getting very hot anyway.

Driving at moderate revs will obviously burn more fuel, therefore more heat will be generated and get the engine hotter quicker. This will mean theres likely to be a shorter time when condensation will build up in the crank case from the water vapour in the combustion gasses, which pass the piston rings. Being as the water vapour will probably contain disolved acidic nasties and start to contaminate the oil, minimising this would be good. Also, the oil will be working harder as theres higher forces acting against it (the engine it actualy producing some torque and doing some work, instead of the pistons merely pumping up and down at idle with very minimal resistance) so that will warm up quicker besides picking up more heat from the hotter top end of the engine.
 
I check my water temp with my Torque pro app for my andriod :D , but yeah roughly on 10 - 15 minutes i would say its ok :p

Looks cool!
Isn't oil temp the important one though?
