In the interest of consolidating inventory to one brand, I am considering AMSOIL Euro Classic 5W-40 for the few Euro vehicles I service. Warranty compliance is a concern since most of these vehicles are MB's that are still under factory or CPO warranty. I have a few out of warranty BMW's that require LL-01 and one Porsche requiring A40 (but is well out of warranty), so formal OEM approval is not a concern on these vehicles.
How does AMSOIL's Classic 5W-40 compare to other options on the market? The other oils I am considering are Motul Xcess 5W-40, Liqui Moly Leichlauf HT 5W-40 and Pentosin HP 5W-30. The three Euro options are widely available from my normal parts supplier and are priced similarly to the AMSOIL (about $6/qt).
Thanks.
