A number of reasons they call for it
1 - they were taken to court in the USA because they never said use synthetic oils---- low SA oil is syn oil by its nature and construct
2- 229.52 calls for HTHS for extended oil change reasons as high as 20,000 miles
3- if you run an oil with 1.5 or higher SA it will be a problem with the rings and DPF lower saps 1.0 or lower are not a problem... people here can scream and yell but they always fail to shown how it would harm a engine or DPF
Schaeffer's states their oil does not contain more than 1.0 -- less is more of a fact .
4- They are trying to comply with ACEA C3 which states .08 is the max SA allowed -- not so much because it will help the engine but because it is a GREEN thing in Europe . Engines will be fine with mid saps oils 1.0 max but they aren't considered green .
The new 2010 Sprinter engines do not have a DPF and they still say use 229.51 rated oil , reason being the spec is more about HTHS and extended oil change interval -- not clogged DPF or EGR .
Like I said in a previous post for some around here
Sulfated Ash is the new boogyman word that is tossed about as an excuse for them to not learn about oils and why they are spec'e the way the are and why companies stated to used them.
Like Mobil Emission Service Protection a huge con to get you to buy the oil at dealerships only no where else could you buy it then they did this when it just came out to rake you over the coals and get your hard earned cash and for Mobil to get top dollar for their product . That is a new low for Mobil but not the last I'd wager,
Others run their mouth --- I am running Schaeffer's S9000 in a 100,000.00 vehicle , I would not do that if it was hurting my van
