Aren't the car's readings constantly going to be changing based upon tire inflation and wear anyway?? And this supposes you have the stock tires and wheels.
Yes, of course. But those factors should not affect the variances noted to any great degree.

speedos in cars have always got to read a percentage fast by law so that we can not blame
them if we are caught speeding

What law is that?

There is a TUV law which says the speedometer must read actual or higher. It's set slightly higher to avoid breaking the law.

I don't completely buy into your thinking. What do you mean abusing?

If one were to tear down and inspect the engines on two like cars at say 100K, what wound be found to be different between the regular used engine form the HiTest used engine? I would consider some good scientific analysis of this.

BTW when I pump regular it is 87 octane.
you got a $80k car so you can save on gas. it is recommended by manufacturer that you use at least 91 AKI. and with each fill up it's about $2.50 to $3.00 difference.

Good thing about this is since you seem so "scientific" about everything. You'd be the only one "smart" enough to try something like this. Prove us wrong please! I can't imagine the amount of carbon build up probably already in your engine.

Aren't those GPS Satellites being placed in orbit by the government ??

We know how accurately they can predict things don't we - just take a look at the government's budget estimates

I never heard of it until now. It is a German law. I wonder if the Germans have a law to set their clocks ahead to avoid a late appointment.

OOPs, Mrs. sixcard does that. Adn it doesn't work for her either.

I have read my owner's manual and I agree with your monetary analysis, but tell me what harm it does to the engine.

Geez, I thought I got ripped at 72K? You paid 80?
