And the 30 vs 40 of the Delo 400 LE 15W-40? This viscosity change to a 30, would that not be better in our low pressure CM-871? Easier to get oil up to the head, or is my thinking off base? Also thinking of cold starts? But, this is a new oil for these newer motors, what have they removed or lessened compared to the 400 LE? I can't find any breakdown on this stuff, so I thought I would ask.

The new, lower viscosity oils are being produces because of EPA mandates to strip even more Zinc away from oils under the guise of "Lower Carbon emissions". I can tell you that they are NOT as good as they use to be, and it is mostly all in the name of "lower carbon emissions" because they think that thinning out the oil will make an engine get better fuel mileage. I am sorry,.. But my truck busts 9 mpg with loaded trailers at 57 mph, and I am running a gallon of GEAR OIL IN IT!. -- It is a crock o sh$T brainwashing strategy play to purposefully shorten the life of all truck engines down to about 435,000 miles instead of a million if you ask me. They have been fighting this battle with the oil makers for a while now to get them to make oils that shorten the life of engines down to the timespan that the emissions components typically last. They also want all the zinc out because it washes away the precious metals in the DOC, etc. and makes it harder for a truck to regen and make good emissions after about 400k miles on the components.

The thinking is that if the engine only last as long as the emissions components,.. Then people will not tamper with them so much, -- They will replace the equipment instead and that would be better for the economy and boost truck sales.

Do what you want to,.. but you need to consider WHY an oil maker would drop viscosity, zinc, moly, etc. knowing it is already a bit low for a particular engine.

Come 2017, gear lubes and hydraulic lubes are going to be the only thing left with good additives in them. I have been saying that for a couple years now.

There was even a couple Detroit DD15 engine that was torn down after half million miles on display using these newer oils vs older oils, and when someone wanted to actually put the parts under microscope and/or even check wear with calipers,.. They quickly and suddenly refused. If your going to put your money where your mouth is,.. Prove it with science,.. and not some bullshit promoted polished up parts that may have revealed the truth if looked at more closely.

It is called CK-4 oil and ALL the articles brag about how it can save you fuel (though it is actually very very negligible and immeasurably minute at best),.. but NONE of them are bragging and showing hard data of how it will protect your engine as well. They are only sticking to generic bullsh$T statements like "backwards compatible" and "just as protective" etc.

My take is going to be that is it not going to be a good thing for your engine long term.
