SN+ bisa banget dipakai di mesin NA juga
Perbedaan SN+ & SN itu di kadar Ca nya, si SN+ itu low Ca (1100 - 1200 ppm) tapi dia geber Mg nya sebagai subtsitusi
Secara umum SN+ lebih baik, karena ada klausul :
- Timing Chain Protection
- Turbo Protection
- LSPI prevention

Maksud spec oli sn plus itu apa yah? Apakah bisa di pake di mobil bensin biasa? Kok kalau saya baca" untuk mesin turbo.
Soalnya mau nyobain ptt 0w20 lg diskon di blibli lumayan nih 1 lt bisa dpt cuman 100.000 haha
Thank you om
Setahu saya SN+ hanya menambahkan LSPI prevention saja dalam engine test requirement nya, tidak menyebutkan harus mengurangi kadar Calcium.
Walaupun pada prakteknya, perusahaan2 oli mengambil langkah pengurangan Calcium untuk mencegah LSPI mengikuti hasil dari percobaan empiris yang dilakukan oleh GM dan Infineum menggunakan mesin GM 2.0L Ecotec LHU engine.
SN+ belum mengatur soal timing chain protection.
Turbo protection secara khusus juga belum diatur, requirement nya masih sama dengan API SN.
API SN+.png
Berbeda dengan dexos1 gen 2 yang sudah mengatur 3 hal tersebut:
- Timing Chain Protection
- Turbo Protection
- LSPI prevention
API SN+ dibuat cuma untuk menjembatani kebutuhan mendesak LSPI prevention karena saat itu ILSAC masih juga belum rampung merumuskan GF-6 yang akan mengatur 3 hal tersebut di atas.
Sifatnya hanya berupa supplement sehingga tetap menggunakan kode API SN ditambah keterangan "plus" atau simbol "+" dibelakangnya.
Karena secara umum masih sama dengan API SN dan hanya berbeda pada penambahan engine test requirement: Sequence IX (Average LSPI events).
ILSAC GF-6 sendiri direncanakan baru akan rampung di pertengahan tahun 2020. CMIIW
API SN PLUS is the interim spec within the lubricants industry that supplements the API SN category for gasoline engine oil performance. It helps bridge the gap between current ILSAC GF-5 and future ILSAC GF-6 specifications.

SN PLUS to mitigate low-speed pre-ignition (LSPILow-Speed Pre-Ignition.

ILSAC GF- engine oil specifications target fuel economy, emission system protection, and enhanced engine oil robustness. GF-6 will balance these equally important needs:
Fuel economy and fuel economy retention
Emission system compatibility
Engine oil robustness to protect engines from wear related to idle stop and failures related to LSPI and turbocharger depositing

Under the industry’s initial plan of attack, LSPI was originally meant to be tackled through the licensing of ILSAC GF-6, the next engine oil specification to replace the existing ILSAC GF-5. Numerous challenges have stretched that timeline far beyond initial expectations, however, prompting the necessity of the API SN Plus supplement.
