Basically it is a compromise between engine torque, road drag, aerodynamics, and other friction factors within the engine.

Cool (but I've got a hedache now) LOL

I know what you mean, I was going to track down the thread I was talking about so that you could have a read but I couldn't stand the agro.

Found some quite usual points on the RAC website.

One of which is:
Your engine will warm up quicker, clear your glass quicker and add miles to the gallon. Engines take longer to warm up when just idling without being under load.

Obviously dont race your engine, or put it under to much strain in the warm up stage as the oil will not be performing or reaching parts as it should.

Hi very skint

A car I was in the other day had a fancy temp gauge that showed the ACTUAL engine temp in F or C. It surprised me that it took over 8 miles before the car was at its optimum temp (188 deg F if I remember correctly).

My preferred start up technique is to crack up the car (diesel), ponce about with seat belt, radio etc (about 30 secs), roll down my drive/hill about 1/2 mile (it's automatic, so no free wheeling, another minute or so), by which time the oil has warmed a bit, everything is lubed up and I'll start to drive normally.

My mum has a little Panda. In her manual it has fuel efficiency for town driving and motorway driving at 56mph. Think 56mph is the way to drive from now on!

Is it true that 56MPH is the most efficient speed to travel at? I remember hearing this as a kid but I dunno how correct it is?

This is why the US set the 55 MPH speed limit in the 70's oil crisis.

Yeah Cumbrian Male

you are absolutely right. The problem is /was that the 55mph is so widely ignored as to be non existent !

The Intersate speed limit varies from state to state and is usually 65-75 mph (or 75-85 mph as it usually transaltes to)
