I'm sure in all reality, a high quality oil like AZO will work fine with the MDS, but I'll use what they want. Also,not as if it matters too much, but I have a Napa Platinum 41372 which is the Ford filter. Little bit longer than the specd Hemi filter, and Napa only offers a gold version of the Hemi filter.
No offense but I am confused. On one hand you talk about what the manual says as if it matters to you and then you are talking about using the wrong weight and uncertified oils and such? Either follow the manual to preserve warranty or run what you want and don't worry about it. Seems like you are doing 50/50 and to me that makes no sense as it doesn't benefit you in any way.
I was speaking more of the weight of the oil. With my other vehicles, I've used oils other than what is recommended, sometimes with good results. I use the 0wXX oils in a couple of vehicles that are spec'd for 5wXX or 10wXX with good results. To me running a 0w20 vs a 5w20 is not really that much difference, and I don't really feel like it would cause any problems to use the 0 over 5. Just wanted other peoples opinions. As far as the warranty goes, I'm not really concerned if the oil is "API Certified" or "Meets API". To me, one is just as good as the other when you are talking high quality brands. I just want to use a oil that gives me piece of mind, and I feel better running the higher end Amsoil vs the XL or OE lines. While others may shake their heads, I don't mind using something like expensive AMSOIL 25k oil for 5k intervals. The money is really not that big of a deal when it comes to making my vehicles happy. I am the service manager a dealer, and I've worked at a couple Chrysler dealers in the past, and never once has there ever been an issue as to what oil was used in a engine that experienced some sort of failure. As long as the owners has maint receipts, or there are no signs of sludge in the engine, things have been fine. Brands, weights, or API's have never come up. Intervals have.
I am very familiar with the Amsoil OE. We sell a TON of it at my dealer. We sell aprox 85-90% Amsoil OE Lof's vs the regular LOF's these days. Customer like the extended drain intervals, and feel confident with the synthetic oil.
