Warming up the car in the morning??
Hi Guys,
In my experience, most modern car manufacturers advise you to drive straight off as soon as your engine has started.
These days we have multigrade engine oils, and the manufacturers specify the right one for you, depending on environmental temperature ranges.
We also have high pressure oil pumps and very precise bearing tolerances.
Metallurgy has come a long way since the Titanic's plates cracked on impact with the iceberg.
Crank shaft bearing journals and cylinder surfaces have sophisticated finishes which verge on the black arts practiced by men in white coats with funny glasses and the letters "Ing" in front of their name.
So I am satisfied that as soon as the "oil can" on the dash goes out, I can engage first gear and drive off.
I am not suggesting that you do this if you have just rolled her off the trailer onto the starting line of a drag strip, and are about to record a new acceleration record.
I am only suggesting that you can drive off and assume that you are pulling out of your driveway into normal town traffic on your way to the next traffic bottleneck.
Under these conditions your engine will be fine.
If on the other hand, you live 20 metres from the start of an autobahn, I would suggest you stay in the slow lane until your engine reaches normal running temperature.
Then feel free to open her up to whatever the authorities allow.
On the other hand, if we go back into the history of the motor car, and are talking about an old engine. For example one like the rare classic British 4 litre six that powers my Vanden Plas Princess and will do a genuine 100 MPH, don't get excited because that's not bad for a 50s limo.
I always wait until the tappets stop ticking before I do more than pull out onto the forecourt of my garage.
Even then I wait until the Rolls Royce gear box decides that it is time to engage top gear, before I press the metal to the floor.
If I drove a 1930s American six, with splash feed, I would be even more careful than I am with the Princess.
These are my thoughts. Hope they help.
