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!!!!


Oh yea? What did he prove wrong? And glad ya didn't listen to who about what?
