Automotive bamboozling

Somehow, this topic just refuses to go away. I know for a fact that I have posted, commented, replied and just, plain ranted about it here and on social media. But the fact that otherwise intelligent people are still falling for the bullsquirt is beginning to alarm me.

Automotive manufacturers have got to be feeding bold-faced lies to the public through all sorts of media outlets in an attempt to keep the public at their financial beck and call. Now that a good number of us have been properly educated on the subject of planned obsolescence and more caqrs are actually being designed and built to last longer, the festering pestilence of corporate greed has reincarnated its feeding frenzy in the form of propaganda designed to encourage people to kill their own cars in under 100,000 miles.

The latest wave of horsefeathers to insult my intelligence is the notion that we no longer need to warm our engines up before driving anywhere.

Setting aside the fact that the companies who ARE NOT contributing to this brainwashing scheme are building cars with COLD ENGINE LIGHTS AND FAST IDLES, here are the facts, like them or not:

YOU CANNOT CHANGE OR DEFY THE LAWS OF PHYSICS, PERIOD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Remember your elementary, middle and high school science classes? What happens to metal when it gets cold? It contracts. What happens when it heats up? It expands. What are automotive engines made of? Metal. What is inside an automotive engine? Moving parts. Lots of moving parts. Lots and lots of metal parts rubbing against other moving parts.

So, do you need to let all your fluids get circulating to operate and to protect the various parts of your engine and transmission? Yes. But there is MORE TO IT, PEOPLE. Physics, folks, physics. When, for example, your crank and pistons are cold, when that metal is contracted, there are gaps between the moving parts. In the case of pistons connected to a crank, take one hand and point a finger. Take your other hand and make a loop with two fingers. Now put your pointing finger in the loop. Now make circles with both hands. Notice how your pointing finger rubs and hits your looped fingers all over the place? Now tighten your loop. Gently squeeze your pointing finger. Make those circles again. Notice how your loops rides smoothly on your finger? That’s the difference between a cold engine and a warmed up engine. That is why engine oil is designed to be thicker when it is cold. But regardless of what kind or weight of oil you use, there are still gaps in which moving parts can rattle around, CHEWING EACH OTHER TO TINY BITS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

When you allow your engine to warm up a bit, which does not take very long at all the way new engines are made, the metal parts expand, and the gaps are closed down to their designed operating specifications.

75% of all engine wear happens during the warmup period. This is a fact. This has been determined and verified by experts and engineers. I did not make it up.

As to wasting gas as putting out excessive emissions, here is another hard, cold fact for you: The ONLY way to keep a cold engine lit is run the mixture rich. That means more gas and less air. This used to be accomplished in carburated engines by closing a plate called the choke. In fuel injected cars, it is done by the computer sending extra gas into the combustion chambers. Either way, when you drive a cold engine, you use more gas and belch out more harmful emissions. Don’t like it? Then STOP DRIVING YOUR DAMNED CARS COLD!

My recommendation for most newer cars is simple. Let the engine run for about 5 minutes. That’s all it should take. 5 minutes. Then, drive GENTLY for the first few miles of your trip to allow everything to come up to its proper operating temperature.

My family and I have been doing this for decade. We keep our cars for an average of 300,000 miles before replacing them. I don’t know about you, but I’ll take 300,000 miles over 50,000 to 100,000 miles any day of the week.

Happy Motoring!
