So is VWB a group III base stock since they don't mention anything about group II a group II+. Wouldn't that put VWB at a higher quality level than even PYB with it's group II+ base stock?
I can't provide my source but there may or may not be truth to this statement
I'm having a hard time believing that the lowest base stock that Valvoline uses is Group III. If so, why don't they label all of their oils synthetic?
Which group 3 terminolgy are you using? If you use the German system G3 means it is an HC synthetic or synthetic technology oil in German and they
label HC oils as fully synthetic in the US or UK. If you use the US four group system then a G3 is a part synthetic or blend. There should be an international standard but thanks to Castrol and their US marketing lawyers it is not going to be the more definitive German system. I look up US or UK oils on German Fleabay or dot de web sites just to find out what they really are in synthetic terms.
If an oil is an HC one it can be very good or not so very, as some mid East rubbish has recently turned up on Fleabay that was tested and found to be slightly out of spec and lacking in additives even though it was an HC oil. The
main reason it was out of SAE spec was basestock related (It would have evapourated rather too fast as it was intended for Russian trucks as a winter oil). The major brands produce good HC oils but not some of the other HC producers, so I regard oil quality rather than actual group label as very important.
Really? What brand or label was this inferior oil. Was it stamped approved or does it state meets or exceeds? Who bottled it?Was it available in NA or only in Russia? Where exactly do you get this info or is it some kind of cloak and dagger type stuff?
I've been a member here for a couple of years now and I have to say that you have brought to light some pretty interesting info. From oil filters made from unobtanium and only made for Volvo,or talking with oil filter lawyers,you must really get around in that plane.
