Another oil question!!!

After reading several posts on here I realized I was running the wrong oil in my 80 with a reblt 4000mi 350. I then switched to VR1 20-50 but that seemed a little too thick for a rebuild. Then I switched to 15-40 Rotella. I am running the small sized oil filter from GM that they gave me for my engine. Does it make a difference when running the Rotella oil? Please don't tell me I need to change the filter now!!! Jay

Don't need to change it now but go with the Wix 51060 next time.
It is the same size as the larger PF35 but has an anti-drainback valve.

Thanks, I am not familiar with wix filters. Is this a product made by NAPA? Jay

Wix makes filters for many different brands, Napa an AC are a couple of them.

At Napa, they have two Wix filters. There is the one with the Wix name on it and a Napa Gold filter, also made by Wix. Now, the Napa Gold is a few bucks more and is the exact same filter as the lower priced Wix named filter. Just buy it. The Napa Gold is the same filter with the Napa name.

And since you asked about oil, I've desided to use a good standard oil such as Valvoline or GTX 10w30 and add a can of GM break-in oil at each change to ensure I get plenty of zinc and other stuff. I think they are taking the zinc out of the Rotella now. I change every 1000 to 1500 miles anyway.
