That's a relief.
I'm often bewildered by the advertising methods used.
There was a famous one some years ago for Slick 50. Basically, the (American) advertiser took 2 identical engines. Treat one. Leave the other untreated.
Then drain oil from both.
Now start the engines. Sure enough, the treated one managed 13 more seconds than the untreated one before finally siezing.
So what? How many of us actually drain the oil from our cars and then drive them?
Also consider this. DuPont Industries - the brains behind Teflon refused to sell it to Slick 50's makers claiming that it had no place in lubricating engine oils.
So, Slick 50 sues DuPont under the restriction of trade laws in the US and forces DuPont to sell Teflon to them!
Thus allowing them to make a product that is potentially destructive to engines and then blame DuPont for the problems.
