I have been lurking on this forum for about a month bow and have learned a great deal from all the posts and write-ups so I figured I would go ahead and post up. I have a 2003 s10 zr2 with the 4.3 in it and was debating on switching to Penzoil Platinum. The truck has about 102000 miles on it and is my daily driver driven about 60 miles a day with most of it being highway. I have been mostly running a mix between a few conventional oils such as penzoil and valvoline with a Fram filter but just want to make it last as long as possile. I bought 2 5qt. jugs of 5w-30 the other day of PP and was going to switch to a Wix filter as well from what I have read. Any input on if it is the right decision or just stick with penzoil yb would be greatly appreciated or if you have a better recomendation and why. If I do run the PP, how many miles do you think I could saftly run the oil too (Yes I know a oil annalisis would be the best for this and I just recieved my kit in the mail the other day? Once again thanks for the help!
