When you have a dozen cars with at least 250,000 miles, I'm not willing to try the latest wizbang idea. I'll keep running 20-50, even in my ACR Neon with 250,000 miles. It still runs like new. If you feel lucky, give something else a try.
and i have cars go well over 100k running 5-30. oil has come a long way. want to stay in 1950 then so be it.
like i said earlier..
its the same bullshit as:
have to change the oil every 3000 miles
a 904 won't hold any power and you have to run a 727
you can't go more then a 3000 stall converter for the street
