quote:Not quite that far back. Standard Oil of Indiana created the first PAO in 1929. As for the next step in synthetic oil, it will come from two fronts: Pennzoil's new synthetic hydrocarbon, PennSyn, (an EOP synthetic basestock) which is very similar to PAO but cheaper to produce. Just as Chevron licenses their IsoSyn technology to other companies who want to produce Group II, II+, and III base oils, Pennzoil (Shell) will, I predict, license the technology to produce this new EOP. Second, we're going to see the continued emergence of GTL (gas-to-liquid) base oils. Shell is at the front of this and is already producing GTL base oil in Malaysia.
