IMO 20wt oil has no place in a 395HP V8 that is rated to tow 10000lbs. There just isn't enough to film strength in most 20wt oils to protect against metal on metal contact. A 160HP 4 banger sure, but not a high horsepower V8.
Disgusting that this didn't cross anyone's mind when they went all in with the "fuel" economy agenda, or did it? JAPAN.
And, the fix is to go to a DI turbo is almost all applications, and that does get you better gas mileage, however it they choose PI turbo they would get probably identical mileage at the wheels on a street as a DI turbo but would have no LSPI and better gas mileage then the 8 cylinders, great for fuel economy and will give a great long lasting engine, but yet they opt for the option that will destroy many more engines. why? JAPAN
I would totally be on board with a PI turbo 6 cylinder hemi, that would make sense and make everyone happy, and that is why it would never happen. Take vvt and mds out, you would have way better actual gas mileage then the current hemi 5.7 and no lspi. Sadly we will never see one, because all of the manufacturers are the same.
You know, how many people would rather see a solid axle on a 1500? It would cost the manu's zero dollars to do so, and man you would have so much more capability with a 4x4. And yet, not one manu's does this, except maybe the new jeep truck. Why? If any manu simply went to a SA in a 1500 it would be wildly successful imo, could easily charge an extra grand for the privilege even as an option, would be great for guys wanting big tires, and yet not a single damn one of them offer it even as an option. Truck guys have no say in how these trucks are being built. If I ever do a gear swap, it will include a SAS.
