They are mistaken at the very least. They may meet certain components of the GF-5 standard, but obviously are not certified. If the bottle picture is recent, that's the first clue. I see no Starburst and no wording in the bottom portion of the API logo.
Most lubricant handbooks mention that 40 grades are not eligible for ILSAC certification.
Swift101: When I switched to Delvac 1 ESP 5w-40 from PYB 5w-30, there was no statistically significant difference in fuel economy. I posted the analysis on it here somewhere.
If I had your car, I'd be probably using what I'm using now, given the price advantage up here. Or, I'd go to a 5w-30 conventional, or if I were really worried about the wording of the manual (which wemay has already investigated with the manufacturer), I'd buy an SN/GF-5 A5/B5 synthetic 5w-30, like M1, Syntec, QSUD, PP, PU, and so forth.
