If the claims are close to accurate for emissions and wear, it's because of improved warm-up times as Ecky stated. However, just one high RPM romp with 300°F oil could easily negate all reduction in wear... |
My easy math was way harder than the math used for those numbers
I understand the percentages, easy math was used for illustrative purposes to try and explain those numbers. I took it a bit far.
I don't understand how those claims could be made if they only apply to the warm-up phase. Is it safe to say that a car is fully warmed-up in the first couple miles? After the first couple miles, wouldn't the benefit be negated?
