Full SAPS/No SAPS for an Asian vehicle

[cammyfive79]

As I learn a bit here, it seems that a general consensus is that European additive packages are geared towards longer drains and sulfur/ash/phosphorus that is higher than standard API mixes. My questions, remedial as it may be, is when/how would you determine that full saps or low saps is better for your particular vehicle?

as a start, what do you mean by no SAPS?
What is recommended from the manufacturer.
engine type.
port or direct injection
turbo or NA
type of emissions equipment.

Assume no manufacturer recommendation on an Asian vehicle aside from “quality synthetic oil”. Port injection and naturally aspirated. For reference I’m using the K24 in my Acura TSX as the subject for this thought experiment.

Depends on if 1 it's prone to lspi and 2 if it burns oil and if so how much.. If lspi and consumption aren't of concern you can run anything.

If that k24 burns no oil or it does but you don't need it to pass emissions and it won't go in any limp mode from emissions equipment not working you can run any high saps oil.

Does not burn any oil and no emissions inspections here in TN.

A general overview:

1. SAPS Content:
   • FS (Full-SAPS): High sulfated ash, phosphorus, and sulfur content. SAPS content is not restricted in any way.
   • MS (Mid-SAPS): Moderate SAPS content, typically below 0.8% sulfated content. Balances engine protection with emissions system compatibility.
   • LS (Low-SAPS): Very low SAPS content, typically below 0.5%. Optimized for the latest emissions systems and newer engines.
2. Compatibility:
   • FS: Suitable for high-performance and some older European engines without advanced emissions controls, including light-duty diesel and gas engines running extended oil drain intervals and experiencing severe conditions.
   • MS: Suitable for newer engines with some level of emissions control systems (Diesel Particulate Filters and two-way catalytic converters, for example).
   • LS: Normally required for the newest European vehicle engines with the most advanced emissions control technologies.
3. Intended Use:
   • FS: High-performance driving, older vehicles.
   • MS: Modern vehicles with a balance of performance and emissions requirements.
   • LS: Newest models requiring maximum emissions system protection.

Thank you. It would appear that my car could/would fall into MS and probably FS without issue.

Yep.

Also remember that the first “S” in SAPS isn’t sulfur in the oil, it’s relating to the ASTM test that uses sulfuric acid to determine the level of ash producing metallic compounds. The ash levels of low or mid-SAPS oils is only significant for those engines where it’s a priority to minimize them.

Good info, thanks. I'll give it a try once my obligatory VRP OCIs conclude.
