Compared to other synthetics I've used over the years (Mobil 1, GC, RP, Pennzoil Platinum, Redline and Amsoil) Pennzoil Ultra no doubt my favorite. And yes that's compared to Redline which was my go to oil for a longtime and Amsoil which I've ran a few times. Ultra is great stuff. That said other than RP I ran all these in a Terminator and Lightning so Ford Modulars and not LS. When I bought my LS1 in December I thought I'd try RP. My next oil change will be Mobil 1 as Costco's had a good deal on it last time I was there, but I think after that I'll switch my Camaro to my go to Pennzoil Ultra. My 03 Lightning runs about like new on it with almost 170k on the odometer.
I'm not sure if the K&N is an "upgrade" from a Wix, I think I'd rather have a Wix, the XP version if possible.
I'll say at Walmart they do have the best price on German Castrol 0W-40. While you're there, the best filter they carry is the Fram Ultra which is a high end synthetic filter, certainly better than the Purolator Classic.

I do lurk quite a bit over at bob is the oil guy forums.
Most synthetic oils on the market today will well serve 80% of users and staying away from cheapo oil filters and having proper oil change intervals go a long way to keep engines happy.

Personal preference and trust is anecdotal; What does the oil analyses say? And why should we trust any of the information from BITOG?

Very good questions.
There are a lot of really **** people (about their oil & filters) over there. Post the slightest thing that's not exactly right and everybody jumps on you. When I post, which is rare, I do so very carefully.
If Penzoil is a sponsor, I'm certain if they post anything out of line, they'd be smacked down pretty quickly.

Regular Pennzoil for years was a mediocre oil, at best. Their Pennzoil Platinum and subsequent flavors have all gotten very good reviews, and more importantly, test results. I use RP because I can get it off the shelf. If I had my d'ruthers, I'd go Amsoil but for some reason I find it tough to order engine oil. No problems ordering ATF though.

Anyone ever try running Motul oil in a LS motor? I've never ran Motul in any of my cars or trucks, but I have used Motul pre-mix in my 2-smoke dirt bikes before. I think Motul is a French company.
It seems like not a lot of people run or even know about Motul but the ones who do have a lot of praise for it as a high quality full synthetic.
