Anyone used low SAPS Amsoil 5w-30 ?
So I put the low SAPS Amsoil this time and the truck feels more responsive and much quicker at high speeds, anyone knows if Low SAPS is an issue ? I do oil changes at 4k

From: http://www.amsoil.com/newsstand/auto...-saps-content/
What is SAPS? SAPS stands for sulfated ash, phosphorus and sulfur. They comprise a significant portion of a motor oil’s additive content. Sulfated ash is not added to oil; it is the result of additives in the oil burning and creating ash. The additives that can produce ash are most commonly used for total base number (TBN), but also help in other areas, like antioxidancy, anti-wear, cleanliness and soot handling. Phosphorus provides anti-wear properties and further antioxidancy, while sulfur contributes antioxidancy, anti-wear properties and engine cleanliness. Basically all the good stuff in oil that they reduce because it clogs DPFs... |

What is SAPS?
SAPS stands for sulfated ash, phosphorus and sulfur. They comprise a significant portion of a motor oil’s additive content. Sulfated ash is not added to oil; it is the result of additives in the oil burning and creating ash. The additives that can produce ash are most commonly used for total base number (TBN), but also help in other areas, like antioxidancy, anti-wear, cleanliness and soot handling. Phosphorus provides anti-wear properties and further antioxidancy, while sulfur contributes antioxidancy, anti-wear properties and engine cleanliness. SAPS Levels Given the beneficial properties these additives impart, it’s easy to assume a higher concentration equals a better oil. But higher SAPS levels can be a detriment to expensive exhaust devices, such as diesel particulate filters (DPFs) and catalysts. The European Automobile Manufacturers’ Association (ACEA) and original equipment manufacturers (OEMs) realized the importance of using motor oil formulated with precise SAPS levels, and lower limits were established in 2010. The three different SAPS levels of European motor oils can be confusing, especially when considering the same viscosity motor oil (5W-40) is available in mid- and full-SAPS AMSOIL European Car Formula options.

Its a good explanation
Seems that they use more expensive additives in place of the SAPS, or the oil takes more refining to remove the sulfur as the lower SAP oils are quite a bit more expensive. ~50% more for the Low-Full Amsoil in Canada. If you look at the data sheets of the different levels of SAPS Amsoil makes, you see that the TBN of the oil decreases dramatically with lower levels. Which is fine unless you are planning for extended drain intervals. --------------------TBN 5w40 Full-SAPS - 10.1 5w40 Mid-SAPS - 8.0 5w30 Low-SAPS - 5.8 |

I ran an UOA on a 10K drain of the Castrol in our 335d, and came back just fine in terms of TBN retention in my use case. I am happy with 10K-12K changes though 80+% of our miles is highway. If your are all city with your X less miles makes sense though IMHO 4K is a bit on the low side - b |

With Dealer oil, rattling is little less on accelerations but doesn't feel the same at high speeds, kinda noisy at all times, slightly better in stop & go but highway speeds feel bogged down comparatively How can you guys explain this difference in behavior between the 2 oils - Dealer Oil was $60, Amsoil $96
