Your chosen warm up method...
Discussion
Get in start up and drive off straight away ,do not let car tick over .and do not take over 2500 rpm untill oil temp is at least 55 degs and not over 3000 rpm untill 60 degs.i no it can be frustrating espcially in the cold weather it can take 20/30 minutets to reach those temps.Any way thats what ive allways done and stuck to. enjoy.......regards jon.......

One of the reasons it can take such a long time to warm up is that you're not going over what is essentially a fast tick-over until 55°C.I've always just driven normally but without silly revs or high loads until 50°C, just as you would in any 'normal' car. It warms up much quicker this way, and also warms up the gearbox / diff. quicker too.
You will read (if you do a search) that people have kept religeously to the <2000rpm till 50 / <3000rpm till 60 from new and their engine has still gone bang.
Still - ATEOTD it's your engine in your P&J, so you pays your money...

Also avoid low revs/labouring when cold, it's as bad as high revs.
I keep it between 2000 and 2500 till 40 degrees (of course in 1st/2nd gear you can use lower revs), between 2000 and 3000 till 60 degress, and max 5000/5500 till 80 degrees.
But even when fully warm, avoid excessive labouring.

"and max 5000/5500 till 80 degrees"
I only reach 80 degrees oil temperature when its very hot or driving in town
with standstill at traffic lights. Even on Autobahn with
150 miles per hour i only catch 60-65 degrees!
So what, i drive carefull first 8-10 kms, not too much load
not over 3000 rpm, driving too slow will cause also
long warming up times (cold outside temps for example),
too fast with high load and/or high revs
is also wrong way. Hard to find the optimum.
Try to feel your engine, take your ears

Very true, although here in the south of France it gets a bit warmer. So you shouldn't use max revs until the oil is HOT (my dealer says no 7000 rpm till 80 degrees but I'm a bit more careful), which means that when warming up the engine, you shouldn't floor it right away when it reaches 60 degrees, but more gradually increase the revs/temp.I only reach 80 degrees oil temperature when its very hot or driving in town

Must say I hardly use more than 6000 rpm anyway outside the track.
So doing 150 mph I assume the engine is at about 6000 rpm. Does anyone know what the max. rev is for cruising?

A few reputable ex-factory service agents have said there is no need to be too anal or panic about it. As most say, light throttle, avoid idling, hard acceleration or labouring, between 2000 & 3000 until 30 degrees then gradually build up until you reach 65-70 degrees.
I live right by a motorway so normally go straight from cold to 2500rpm which is almost 70mph and barely touching the throttle so no strain on the engine from stop-starts. Must admit I was nervous using it in winter when the starting oil temp was 0 degrees.
Reckon those opting for heavier oil grades such as SAE 50 might need a longer warm up time before giving it beans.

5W50 is cold same as 5W30!
5 is cold viscositiy, 30 is warm viscosity
If you use 15W40 for example cold viscosity is 3 times higher
(thicker oil) and oil needs min. 3 times longer to reach
the lubricating points!
Sae 50 is Harley oil and cannot be used for our TVRs!

Get in, drive off. Enjoy car.
Life is too short to worry about things. In my opinion if the engine is going to go bang, it will go bang, regardless of how "anal" you are with warm up procedures.
First Tuscan: engine lasted 22,000 miles before needing a rebuild. Drove it normally, didn't care too much about revs and temperatures.
Second Tuscan: engine lasted 4 months, handed keys back and walked away.
Third Tuscan, current one: 07 plate, 8000 miles done, no worries.
