The 4.3 does have a positive reputation. In fact when I ordered the truck I ordered the 4.3 specifically because of the number we see at the dealership with high miles. Many of which are abused work-trucks.

The SOPUS HQ is indeed in Houston. That doesn't mean that the product is actually created there. The company's tentacles extend far, far beyond Houston...
Funny you mention that about the location of Shell, I work literally across the street from their huge refinery. They employ much of my hometown. So, their "tentacles" at least extend from down-town to my town.

I guess I am a product of the synthetic generation. Now that I am driving a bit less time may out pace miles in terms of aging the truck in reality. Still, this site exists because people agonize over what is best for their given circumstance.
The difference in price these days between PYB and PP isn`t that much. And the small difference in price is money well spent if it gives you piece of mind. I`m currently running dino (and always have), but after reading bitog for a few months (and doing more research elsewhere), I`ve decided that syns are a better fit for me and I already have the PP bought for my next oil change.
Even if you go to the syn route, I`d still change it out twice a year (November and April) - assuming you don`t put enough miles on it to justify more frequent changes under your current severe maintenance schedule.
I agree that the difference in price in somewhat negligible when weighed against the piece of mind synthetic offers. Also, PP is a deal considering what I have been spending on the M1 EP and filter every ~3000. LOL I think if those "oil police" mentioned where going to make an arrest they may have to start with me

I dont buy into the 'long drive to burn off fuel' ,it would cost me more in gas than a 5 qt jug from walmart (11.50)for any good dino on roll back.Someone will shoot holes in my theory ,I'm sure.
Interesting! I'm ashamed to admit I hadn't really thought about the fuel dilution, at least not directly, but that is a consideration as well. I need to study up on how all that works in general. I have spent so much time buried in oil specs. I recall seeing a chart, on the AMSoil site I believe, that listed Mobil 1 as having a very strong resistance to fuel dilution. Typical that I would discuss a concern full circle... Do synthetics generally have a higher tolerance for this? Or, will changing the oil every 3000 render this somewhat irrelevant no matter what I use? ...the mind reels
