PAO vs hydrocracked oil

shietpilot

Hi all

I've seen numerous posts on Boards talking about different brands of engine oil and base oil groups. I've seen that Group III oils are hydrocracked and Group IV oils are PAO and apparently Group IV oils are better. I also saw that Mobil1 oils are Group IV.

Anyway so I go onto Amazon.de (because in Germany it's illegal to brand hydrocracked oil as fully synthetic), found myself some Ford spec oil from Mobil1 and the packaging clearly says "SHC-Synthese" which is hydrocracked oil.

In fact looking at the Mobil 1 oils on Amazon, they all seem to be SHC marked (Synthetic HydroCracked). Is there any Group IV oils available at all or are these claims that Mobil1 is a Group IV oil are false?

The only oil I've found that says fully synthetic is Motul: https://www.amazon.de/Motul-8100-Eco-nergy-5W-30-5L/dp/B004WDDD82/ref=sr_1_2?ie=UTF8&qid=1469713186&sr=8-2&keywords=motul+5w30+a5

There are some. Found 4 here:

There are more alright, but rare as hens teeth.

Generally, if you want to check if oil is PAO or not, just do what you did - compare it to its German version.

Is it really worth it going for a PAO oil though? Ford dealerships for example use Castrol which is hydrocracked. Fords own brand oil which is also made by Castrol is hydrocracked too.

IMO - it depends on engine's age and condition.

Dealers use what they have a contract with, if you know what I mean.

SHC=Synthetic Hydro Carbon

Nice, so more BS from oil threads on forums. Seems like any oil with the correct spec is good enough.

PAO are better when working in extreme condition, such as heat and are able to cope with it better - transport it away from the pistons etc. For a car that is not part of a competition - HC oil will actually be a better choice.

HC bases are capable of carrying the additives much better. It takes serious engineering and a half of the elements tables to build a stable PAO based oil.

No, sir.

And finally, this:

[...] HC-Öle werden bei API Group II teilweise, bei API Group III sollständig, durch Hydrocracking gewonnen. [...]

German alright, but IMO needs no translation.

Tldr.
If I buy a 208 litre drum of SHC Cibus 46,
Shc in this instance stands for synthetic hydro carbon,not hydrocracked.

Pretty much.
Once viscosity grades are on point the rest is just additives and unless your driving a high performance car ie.formula 1 for example, it's not going to have a massive impact.

Yeah, industrial machinery lubricant compared to motor oil - perfect comparison indeed.

Keep talking...

Smh.
Took you all of two days to Google it.Well done you're on the ball.
It doesn't matter if it's hydraulic oil as stated above or engine oil.
The thread is about PAO vs Hydrocracked.. The example I used was to highlight (and I'll say it again)SHC stands for synthetic hydro carbon.

I was away last 2 days, but its actually none of your business at all.

And just to inform you if you did not spot it yet - we're talking about HC Synthese oils not SHC oils.
