Hydrotreated heavy paraffinic oil: is this oil mineral or synthetic? If synthetic, which group?

Thanks. So it is mineral oil.

Hydrotreated, yes.

Add: Although the technology is advancing and achieving higher VI and lower saturates than previously.

Would that be group II or III ? or depends?

Here goes a noob question, is hydrotreated and hydrocracked two different entities?

 

[Gokhan]

Mineral means petroleum-derived in this context. Virtually any oil is mineral oil. Exceptions are vegetable oil, PAO, POE, etc. You can exclude GTL as well. There is no difference between Group II and Group III except for the viscosity index (VI). They are produced by the same processes. Group I is true mineral oil, as it has the least amount of processing.

They are the same. There is no difference between Group II and Group III other than the viscosity index (VI), which depends on the "severity" (resulting in higher VI) or "mildness" (resulting in lower VI) of the processing. See my post above.

So is it possible that anga's oil is a group 3 synthetic (since it says hydrotreated mineral oil)?

If he has the specs, including the HTHS, I can figure out the base-oil VI using my calculator and give an answer.

unlike germany a ruling in 1999 allowed highly refined CRUDE oils to be sold + marketed as synthetic!!! actually castrol was touting their syntec illegally IMO before the change when mobil was still a costlier real synthetic group IV oil, so today most everyones lower priced synthetics are mostly if not all group III oils forever clouding the definition of synthetic IMO

OT: Except I expect most BITOG'rs would take a currently formulated Group III from late 2022 over a formulation with PAO from 1999.

Never mind. Not even worth it.

Actually Chevrolet had a problem with cooling systems not aluminum engines

I haven't seen where hydrotreated has met the VI and saturates requirements for a Group III base stock. But if it did then it would qualify. Group designations I, II and III do not dictate composition (and neither does Group V really, other than to say anything but any of the other Groups).
