It's amazing TBH...I need this.that's more Euro sexy than the Liquimoly Ceratec or Molygen Protect can!! Has @tig1 seen this???

I suspect SHC was, "Synthetic HydroCarbon"Nowadays Mobil only use SHC name for gear oil.
There was an amusing thing, by the way. To be precise, Mobil's rendition - Synthesized HC.Synthetic HydroCarbon
I remember some of those discussions in the Trade papers.There was an amusing thing, by the way. To be precise, Mobil's rendition - Synthesized HC.

During the period of 1973-78, the term "synthetic" did not enjoy a particularly favorable reputation. Mobil made an unsuccessful attempt to promote the usage of the term "synthesized" instead of "synthetic"

It reflects the intricacies of language and marketing strategies during that specific timeframe.

Can't recall when CAFE started. Curious if that era was the beginning of CAFE or if Mobil 1 was ahead of the game in that regard or if "fuel savings" was one of the side benefits of synthetic oil development and was a comeback or an afterthought in response to Exxon?
actually GTL outperforms pao in many categories according to GokhanThat was when Mobil cared about using REAL SYNTHETIC. Now all they use is a GPIII or GTL and say it performs just as well as the real thing deal with it
yeah, suremy friend a now retired Ducati + club racer noted how the mobil oils went DOWNHILL after the mobil castrol issue on real synthetics!!
I don’t see how this is true. They end up basically the same.actually GTL outperforms pao in many categories according to Gokhan

GTL doesn't have the seal shrink issue and has slightly better solubility, and may, depending on what PAO you are comparing it to, have lower Noack. But, PAO still beats it on cold temperature performance, being wax-free, while GTL has less wax than your typical Group III, but still has some, so requires PPD's. PAO may also offer superior oxidation resistance.actually GTL outperforms pao in many categories according to Gokhan
The Qatar GTL slate (QHVI) was originally (not sure if they've broadened it since), 3, 4 and 8cSt.
Gokhan have interesting post about GTL and Pao.GTL doesn't have the seal shrink issue and has slightly better solubility, and may, depending on what PAO you are comparing it to, have lower Noack.

GTL is less expensive to produce, which is why it is becoming so common now.
One of the main issues is that the slate of GTL base oils is relatively narrow. The Qatar GTL slate (QHVI) was originally (not sure if they've broadened it since), 3, 4 and 8cSt. Mobil has 2, 3, 4, 5, 6, 8, 10, 40, 65, 100 and 150 in the SpectraSyn PAO family in comparison.
Yes, though some of that is opinion.Gokhan have interesting post about GTL and Pao.
Still is and it's 0w20 ugly sibling lol5-20 back then was a radical idea.
When it came out in the 70’s, I put it in my new slant 6 Plymouth Duster. Engine started using it like crazy. No leaks so I figured it was blowing by the rings or valve stems. Switched back to regular oil.Kind of. SAE20 was common, and so was 20W-20 (and 25W-20) but these were primarily spec'd for cold temperature operation in engines that might have spec'd something heavier like an SAE30 during warmer temperatures. The introduction of the 5W-xx Winter grade with the xW-20 SAE grade was new, and Mobil's boldness about recommending it for applications that called for heavier oils like 10W-40 was also rather revolutionary at the time.
The Euro-specific stuff that @ArthurArgentum posted above was news to me, I was familiar with the North American side of the story, but not the earlier SHC one.
As an interesting tangent on that:
SHC now denotes a group III oil in Europe (synthetic technology), not PAO-based. Quite literally the opposite of what that same acronym meant originally, which was a synthesized hydrocarbon (PAO) built from ethylene. Mobil's SHC oils are not "Vollsynthetisch", whereas, the original product was. Very interesting to see how that evolved.
