It would be easy enough to get the car not to start with a switch keeping the ignition for working or the fuel the same. Be interesting to see if it makes much pressure at that rpm.

In the past I have used a starter to prelube an engine before the first start. No plugs in and mechanical gauge on so I could see oil pressure build. Lately I have set up and actual prelube system.
I think the key to proper warm up is to put a light load on an engine. I also try not to go over 2000rpm in my truck until it is at least partly warmed up in winter conditions.

Wouldn't that imply that BMW did actually use the lights to indicate what it's safe and what's not? I mean if that wasn't the case then why would there be any variation from 50 degree starts and 0 degree starts? More speculation of course but maybe it really is okay to replace it out, but I'm not going to try.
I am certain the original buyers of these took those lights literally and you can bet they reved right up to them on cold starts.

General question since we're talking about filling up/gas in this thread...

My friend religiously fills up his tank at a quarter-to-empty every time.. I basically wait until i only have a few miles left on my range. His reasoning is it puts stress on the fuel pump when the tank is near empty... Thoughts?

I don't understand what you're trying to ask.

The fuel in the tank cools the pump

I would think most people that bought these cars were performance fans. However, just as we are discussing here, every car owner thinks differently. Some drove them lightly, others just drove them like they stole them as the saying goes. Most by now have gone through 2 or 3 owners if not 5 or 6. Some were maintained others not so much. In other words pretty much like any other used car out there.
I always remember a fellow I used to know. He would get in a car at -25F and just rev the heck out of it when starting. His theory was that the oil gets to things faster. I still cringe when I think of that. You do not want to buy his old cars!
