Royal Purple engine oil: 10W30 or 20W50?
Both of these viscosities seem popular among board members.
Which would be better for my climate? (Oklahoma)
10W30 or 20W50
Thanks,
Victor

I run 20w50 Amsoil all year round in my TII and will in my FD once that is up as well. But of course, I live in Arizona, so cold temps are usually not too cold at all

The danger isn't when the car is running, its at inital start up. I am telling, put a quart outside and then you will see how thick the oil gets. Now imagine when you first start your car, it takes awhile for the oil to start flowing threw the oil passages. Most damage is done durring initial start-up.
It just doesn't make sense to run 20w-50 in the winter.

Unless you driving your car on the track or in very hot climate, there is no reason to use anything other than 10w30 (higher range synthetics not included).

I swear by RP oil.... I run 20W50, even now in the winter time I use 20W50 RP. I DID use Mobil 1 15W50 like 2 oil changes ago ( 2 months), saw a notice, but still went back to 20W50.
