Just bought a new to me rig....2002 Chevy Blazer 4x4, 4.3 liter. Doing the usual research to see what everyone likes. I've read that Wix, my usual go to filterator, has changed a lot recently after becoming an M&H brand. Long story short, I also read that O'Reilly Microgard Select oil filters are a very good, solid alternative. I'll say that I put one of the green Microgard Select air filters in the Blazer and was impressed with it's construction for the price. I get a discount at my local O'Reilly's too. So what's the scoop on the MGS oil filters? Probably going to be using Valvoline Max Life 5W-30 with a 5k mile OCI to start....previous owner always used HiMi oil at her local Gulf oil change center. What say you, smarty oil geeks?
