I am researching motor oils to use our new Benz. Mercedes spec is MB 229.51 low SAPS oil. The only oil I can find locally is Pennzoil Euro L. Our local stores don't carry any Mobil 1 with that spec and the MB dealership is over an hour a way. I plan on changing my own oil. I'm a huge Kendall GT-1 Full Syn fan, so I've been looking for the Euro Plus but so far no luck.
While browsing the Kendall site I noticed something strange. It's my understanding that low SAPS refers to low sulfated ash / phosphorous and sulfur. According to the Kendall GT-1 with Liquid Titanium (regular SN syn) Product Data Sheet, this oil has less SAPS than their MB spec'd Euro+. If MB wants me to use a low SAPS oil, wouldn't it behoove me to use the one with the least amount? The low SAPS is for the particulate filter this engine apparently has. It's a gas turbo GDI 2.0. The Euro+ carries the MB 229.51 approval and the GT-1 does not.
Thoughts?
