Hydro-processed VS Hydrocracked?

[BlueOvalFitter]

The new Motorcraft 5W30 oil with the SM,SL rating reads;"synthetic/hydro-processed" while the older Motorcraft 5W30 SL rated oil reads;"synthetic hydrocracked". What is the difference? I originally bought 3 of each,due to not having anymore of the newer SM oil.Are they both the same oil? I then bought 3 cases of the newer SM rated oil,@$1.42 a quart.

It's probably just a case of semantics.

Huh?

 

[doctorr]

The oil industry used 'cat crackers' for years, using a fluidized catalyst to thermally break the heavy oil molecules down.
Then new technology came along using hydrogen to break the bonds, over a different catalyst.
This process automatically became known as 'hydrocracking'.
Any process that uses H2 could be called hydroprocessing.
If you want REAL semantics, my refinery uses only SYNTHETIC CRUDE (that is probably an oxymoron.)
That would imply that all the products, even the gasoline and jet fuel, could be called synthetic......

Doctorr, were hearing about new oil being substantially GpIII at no additional cost. Is this possible or likely.

Has there been some new technology to reduce the cost substantially??

We have heard that some oil can be 75% or more hydrocracked and sell for standard price.

What do you think??

Table 3 is interesting

Haley10 - you are probably asking the wrong guy about finished lube oils, I am in (the worlds most modern) hydrogen intensive oil refinery, but we make no lubes, just diesel, railfuel, jet and gas.

Ok,back to my original question; "Are both the oils I stated in my original post the same?"

 

[Blue99]

IMHO, No, the amount of "synthetic" (Grp III) in the Motorcraft 5W-30 SM version is 50% or more, based on the similar ConocoPhillips versions.

The SL/GF-3 version has a back label reference to synthetic base oil. This is more than likely just a correction fluid amount for pour point or volatility.

As far as the terms, & a follow-up to the Doctorr's comments, hydro-processing is a more general term and could include hydrocracking plus hydroisomerization or hydro-finishing to reform aromatics & reform or remove wax.

don't they mean the same thing?
