which German makes we are talking about? These are the only ones approved by MB
MB sheet 229.1 approved oils
Pentosin Pentosynth TS 10W-40
Pentosin Pentosynth 5W-40
Pentosin Pentoturbo 15W-40
Pentosin Diesel 10W-40
MB sheet 229.3 approved oils
Pentosin Pentospeed 0W-30 VS
I got a '96 Audi with a 2.8 12v engine.
From the Pentosin site:
PENTOSPEED 0W-30 VS* is approved by:
DaimlerChrysler (MB 229.3)
VW 502/505 (1.97)
Audi 503.01 (1/2000)
PENTOSYNTH 5W-40 is approved by:
DaimlerChrysler (MB 229.1)
PENTOSYNTH 5W-50 surpasses PENTOSYNTH 5W-40, if it is used in high power engines, including multivalve petrol turbocharged engines. It may also be used in racing cars and is very well suitable for four stroke motorcycle engines.
But, if you have a source for any of the following oils would you please let me know?
Aral SuperTronic M SAE 5W-30
Elf Excellium 229.5 5W-30
Fuchs Titan Supersyn SL MB SAE 5W-30
Shell Helix Ultra AB SAE 5W-30
Total Quartz 5W30
I would think the German Shell site has info on the Ultra Helix. Sorry, I haven't seen any of the oils you've mentioned here in the US, but Ferrari dealers should carry the Shell Ultra Helix. I wonder if it's $20 for a liter, though.
I did a couple of runs with Pentosin 5W-40 in my VW 1.8T. If you do a search for Pentosin or Pentosynth in the UOA section you'll see the results. The oil performed very well in my application. When GC became available locally I switched to that.
