Mengenal berbagai zat penting pada additive oli

zat zat di bawah ini umumnya terkandung pada oli mesin bensin & oli mesin Diesel yang kita gunakan, hanya saja beda merek oli / beda type oli komposisi-nya berbeda beda.


Additive Metals:

Calcium (Ca):
Calcium is an anti-corrosion additive. It is found in high concentrations in engine oils, and never found in R&O (Rust and Oxidation) lubricants. It is the primary additive in most engine oils that provides acid neutralization. Generally, the higher the calcium amount in a new engine lubricant, the higher the Total Base Number, or level of protection against corrosive acid build-up. Calcium can be found as high as 4000 or 5000 parts per million (ppm) range in some high-base diesel engine oils, but generally found in the 500 - 800 ppm range in today's gasoline engine oils.

Magnesium (Mg):
Magnesium, like calcium, is an anti-corrosion additive. It neutralizes acids. Magnesium also provides some anti-wear properties. It is never found in R&O oils. In industrial Anti-Wear (AW) and Extreme Pressure (EP) industrial lubricants, magnesium is usually found below 150 ppm in new lubricants. In Engine oils, magnesium may be 300 ppm or higher, depending on the formulation and base number.

Barium (Ba):
Barium provides tremendous anti-wear (AW) and some extreme-pressure (EP) properties, but is found in only a few specialty lubricants. When found, it is usually below 300 ppm in new lubricants.
Phosphorus (P): Phosphorus is an anti-wear, anti-corrosion additive. It can be found alone, or with zinc as part of a ZDDP additive package. Phosphorus can be found over 1200 ppm in some diesel engine oils. In industrial AW and EP lubricants, it is usually under 500 ppm.

Zinc (Zn):
Zinc provides anti-wear properties. It is also part of the ZDDP additive package with phosphorus, where it is generally found at or near the same level as phosphorus. When found without phosphorus, it is generally found below 200 ppm.

Molybdenum (Mo):
Molybdenum, or 'moly', is an anti-wear and extreme pressure additive. It is generally found in gear oils and some engine oils. It can also be found as molybdenum di-sulfide, a solid lubricant additive. It can be found as high as 5000 ppm in some specialty gear oils, but is usually in the 100 ppm range.

Antimony (Sb):
Antimony is also an EP lubricant found in some Gear oils. Generally is it found below 100 ppm.
Silicon (Si): Silicon is most often found as a contaminant, however, in some engine and gear oils it is used as an anti-foam additive. As an additive, it is most often found below 20 ppm.

Boron (B):
Boron is most often found as a contaminant from cooling water incursion, some gear and engine oils use boron to provide both anti-wear and detergent properties. When found as an additive, it is generally found less than 300 ppm.


Zat2 yg jarang sekali digunakan, tapi ada yg pake :

Copper (Cu):
Copper is usually found as a wear metal, however, a few lubricants have a copper based anti-wear package. These lubricants will generally have less than 300 ppm copper present.

Sodium (Na):
Sodium is usually considered a contaminant, however, sodium is also found as an incidental additive as a result of the metallic salt additives. In some AW and EP lubricants, sodium may be found as high as 100 ppm.

Potassium (K):
With very few exceptions, potassium present in lubricants indicate cooling water. A few gear lubricants, however, use potassium as an anti-corrosion additive. When found as an additive, it will generally be in the 150 ppm range.

Wih, mantap om infonya. Terima kasih udah bagi2 info, nubie kayak ane jadi kebantu.

Kalau aditif oli yg terpisah seperti LM ceratec perna coba om?

LM Ceratec ngeliats lab analysis nya isinya mostly Ammonium Molybdate dan ada sedikit Boron Nitride

di BITOG ada tuh

Kalo kita mau tambah additip zat Moly, pastikan oli yg kita gunakan belum ada zat Moly-nya (liat VOA / UOA dulu)

Sebab zat Moly kalo kebanyakan konon efeknya juga gak bagus

Kalo om Turbo percaya aditif yg dicampurin ke oli mesin?

Atau cukup pakai oli bisa tapi rajin ganti?

Basically saya penganut aliran "pakai oli apa adanya & anti additip2-an"

tapi skg ini saya lagi test kombinasi Delvac1 + LM MoS2 krn ngeliat VOA nya Delvac1 dia gak ada Moly-nya, jadi saya berani tambahin, juga ngeliat VOA nya si LM MoS2 dia isinya murni Moly

Tambah kira2 sekitar 75 ppm aja

Additip oli lain yg menarik = Schaeffer Moly EP, isinya ada Antimony 23 ppm, ada Moly & Phospor dlm jumlah yg sgt kecil juga.......kalau oli yg kita pake ga ada antimony-nya maka scr teoritis bisa pake

Nah pak, apakah aditif oli yg baik untuk mesin diesel jg baik untuk mesin bensin? Atau sebaliknya?

Maaf banyak nanya pak, maklum masi nubie pak.

Pada dasarnya oli dan zat2 additive pada oli diesel dan bensin itu SAMA SAJA.....yg berbeda adalah persentasi di zat2 tertentu.....utk Diesel HDEO biasanya zat detergent (Ca / Mg) juga antiwear (ZDDP) umumnya lebih tinggi drpd oli mesin bensin PCMO

Gini deh, daripada bingung, mending pake oli apa adanya lah, jangan campur2 additip........diskusi pemilihan jenis oli bisa kita lanjutkan di trit Ranking & pemilihan oli mesin

kalau saya campur additip tambahan di oli itu biasanya saya terawang dulu VOA si oli maupun additip, utk pastikan zat2 di dalamnya nggak saling tumpang tindih.......misal kalo suatu oli yg kandungan Moly nya udah tinggi tentu nggak boleh kita kasih additip Moly lagi

HDEO = Heavy Duty Engine Oil

PCMO = Passenger Car Motor OIl

VOA = Virgin Oil Analysis

UOA = Used Oil Analysis

OCI = Oil Change Interval

Oh gt ya om Turbo. Ane sendiri ga perna jg pake aditip oli. Mending uangnya buat ganti oli lebih teratur. Hehe.

[esperwe]

Klo militec gmn om turbo...??? Katanya bukan aditif ato treatmen tp nyebutnya sbg metal conditioner...
Klo dibanding ma moly ep mending manna om turbo?
