Add packs and specifications

Talking to the R&D Manager at Liqui-Moly, I was recommended their Synthoil High Tech 5W-40 for my Grand Marquis. I was told the reason behind this is the add pack found in the 5W-40.

Currently, I'm using their Synthoil Longtime 0W-30, which meets the same specifications as Synthoil 5W-40 - SM/CF and A3/B4-04. The 0w30 is recommended for applications requiring MB 229.3, VW 502/505 and BMW LL-98. The 5W-40 is recommended for the same applications plus Porsche A40.

Considering both products meet the same specs, would the add packs not be similar?

Perhaps he was considering the ambient temperature in your location ?

Sorry, bit of a confusion there. The product they recommended was Leichtlauf High Tech 5W-40, which meets the following specifications:

- API SN/CF
- ACEA A3-08/B4-08
- BMW Longlife-01
- MB-Approval 229.5
- Porsche A40
- Renault RN 0700, 0710
- VW 502 00/505 00

I think the fact that it clears A3/B4-08 is more than enough reason to use it, and that's completely ignoring MB Sheet 229.5.
