I think the lines are blurred now with some of the better Gr3 oils.Sure but from a performance perspective GTL has more in common with PAO than Gr3 made from crude oil.

I'm not sure what you're getting at in your first statement. GTL is a group III base stock that is derived from a synthetic feedstock. Yes, that is correct.Maybe some clarification? Group III base stock can come from synthetic base stocks, but not necessarily GTL. GTL originates from natural gas to make Group III base stock. Is this not correct?

How the GTL production process works
The GTL process consists of three stages:
In the first stage synthesis gas, a mixture of hydrogen and carbon monoxide, is manufactured from natural gas by partial oxidation. Impurities are removed from the syngas.
A second stage converts the synthesis gas into liquid hydrocarbons using a catalyst. In this stage, a liquid is formed which looks and feels like wax at room temperature.
The final stage is cracking and isomerisation, which “tailors” the molecule chains into products with desired properties. This yields high-quality liquids such as diesel, kerosene and lubricant oil.
....a synthetic feed stock which in turn is derived from natural gas. Be concise. Synthetic feedstocks also have other sources. It has to be natural gas derived synthetic feedstock to get a GTL product. That’s all I am saying.I'm not sure what you're getting at in your first statement. GTL is a group III base stock that is derived from a synthetic feedstock. Yes, that is correct.

Especially not when Mobil 1 ESP is on the shelf at Walmart for $28.The real question - since QS Euro can be had for $23/5QT whereas PPE costs about $46/5qt in the US…about double the price, is there any real benefit? Say for a high performance vehicle? Daily haulers, probably not worth it and a shorter interval may be more beneficial.
Snagged it!Just semantics. “ GTL is a hydro cracked group III base stock that is derived from natural gas”.
Considering that they are both Group III and qualify for the same interchange, no. If an approval had a specific VI or saturates requirement then it wouldn’t require a GTL base stock per se. Other Group III bases can meet that, or a blend. Nothing would “require” it to be GTL produced.Are there any approvals that an oil with a GTL base stock can or would pass that a group III can't?
Perhaps some ultra-low viscosity oils likes 0w16 where GTL can be substituted for PAO but crude based Gr3 cannot.Are there any approvals that an oil with a GTL base stock can or would pass that a group III can't?
Of course it can as long as the VI, saturates and other attributes are acceptable. A GTL base Group III requires less hydrocracking to achieve those results but there are high-quality Group III bases besides those derived from GTL.Perhaps some ultra-low viscosity oils likes 0w16 where GTL can be substituted for PAO but crude based Gr3 cannot.
Are there any low viscosity crude-based Gr3 which match that of GTL? Genuinely interested because I looked before posting and couldn't find any info.Of course it can as long as the VI, saturates and other attributes are acceptable. A GTL base Group III requires less hydrocracking to achieve those results but there are high-quality Group III bases besides those derived from GTL.
That's a good question. GTL vs VISOM vs Yubase for example:Are there any low viscosity crude-based Gr3 which match that of GTL? Genuinely interested because I looked before posting and couldn't find any info.
