I'll just add that sn+ is neither good not bad for a hemi persay, usually they simply lower CA and add MAG which is a neutral move imo. Still look at other indicators when choosing an oil such as viscosity and moly. You can get sn+ with high moly, I believe that is what amsoil did.
SN+ was a compromise because they have not been able to successfully achieve the goals of gf-6, but gf-5 oils where leaving the possibility of lspi in di engines. So they allowed a small measure such as lowering CA and adding MAG to help combat lspi. This is a mid step behind what they are trying to do and develop gf-6, which will be lspi friendly and supposedly will protect against wear, which I am very skeptical about as you all should be as well. You can look at sn+ as being gf5.5, as in they are heading in the right direction for a one oil fits all category. I serious doubt anything in this category will be better for a hemi then the hearty gf-5 oils. We have old engines that benefit from older built oils, modern engines don't resemble our engines in any way. One size fits all means we ********* that believe their **** will have engines not protected the same as if we didn't listen to their garbage.
The gov't has a goal period, if it was them alone gf-6 would have already happened and we would be running sparce oil in our engines. Thankfully the auto manu's and oil manu's have some say in this, so they used timing chain wear to slow the gov'ts roll. However, I am betting dime to donuts the gf-6 will protect an engine, but nowhere near a long oci. So if someone decides to go with whatever they come up with in gf-6, consider a short oil change interval! Especially guys running 20 weight. Here's the thing, they are adding a bunch of stuff to these oils for carbon deposits, however the more things you add to a base oil, the more that base oil will fail to protect in the long run. They still haven't developed self healing vii's yet, and they refuse to require PAO/Esters an as options. So why do they think they can squeeze that much more out of ground oil then they currently have? It's just not working, they keep extending the gf-6 deadline for years and years, but some day this **** will hit the shelves. So you guys might want to stock up on your favorite oils when you see them on sale. When gf-6 hits, you wont be able to buy your favorite oil in gf-5, just like you can't buy gf-4 now. Only a few oils you can get older spec's, some of the diesel oils. But mainstream **** leaves old specs alone. If you like that PUP 0w40, stock up. I bought at least 3 years worth PUP 5w30 for the wife's car, likely I will get a couple more if they keep running that deal on amazon.
