Re: 5 W 30, revisited
You really need to understand what the numbers mean....
For hot running, the 30 part is the only important one. 0W30, 5W30,
10W30 and 20W30 and straight 30 are all the same.
The only difference you can make for real hot is to up the second number
to 40 or 50.
It is the 0, 5, 10, and 20 before the W that are of concern in the cold
with the 0 being the thinnest in the cold temps.
The books give you a 'range' of temperatures to use the oils. If you
never get much below freezing 10/30 is just fine.
