Oil and filters? It is the question of the day

[chrismoore701]

Ok guys let's hear your thoughts on this topic. I have a 79 c10 and an 09 Silverado. I used to be a penzoil and fram kind of guy but I have since changed my ways after hearing talk on here. I use either purelator or wix. And mobile one pure synthetic. But that is crazy expensive. What do you guys think about valvoline.

So what are you guys running? What combo?

And when you pick a brand of oil should you stick with it? Or is it ok to get what's on sale?

Thanks
