Dont worry too much about temps mate, if you let your car get up to temp (engine temp gauge on dash) then leave it another 5mins driving around off boost, then you will be fine, if you think about it, wasrm your car up on the drive (obviously with you in it) then set off on your journey, by the time you have hit a main road (depending on where you live) the engine and oil shoud be up to temp, unless you live on a motorway slip road
