Oil viscosity - why the 20W-50 BS?

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


Humm the older guy that built my engine proved alot of these " new Guys" wrong. Told me I couldn't run this or needed that" I'm glad I didn't listen to them, new guy" Oh you can't run a 1 7/8 header on a 408. Bullshit I am and it's great. Oh that 670 carb is amll bullshit. I'll listen to the guys that built engines in 50's and 60''s anyday!!!!
