APPROVALS: API SL/CF, A3/B3, A3/B4, 502, 505, LL01, M229.5, GM-LL-B-025
Anyone can stamp a list of recommended for this or that car on their cans. That is in no way illegal, apart from a very slight chance of a class action law suit in the US.
Not sure if it's a typo, but no oil can be both an A3/B3 and A3/B4, as a B4 is a better spec than B3. For the A40 spec it would have to be an Acea A3/B4 or better spec. The RN0700 spec that I like to see for my TDI is more difficult to meet than A40.
Most of the OEM specs in your list apart from the Porsche one are real easy to meet. Almost any oil of the correct viscosity range can meet the VW specs listed by the Nitwit fan, as VW are not fussy when they list oils that are not used by their dealers in Germany.
PS: Just had a look at their 5w30 on the Penta web site:
www.pentosin.net and it is completly different in specs and so called approvals. It's an Acea C3 low saps which regardless of what every C3 rated oil company says is not forwards compatible to A3/B4.
The Porsche approval is only an A30, not the A40 listed by Nitwitfan.
