Abstract
Banyak sekali faktor yang mempengaruhi umur pakai oli pada sepeda motor seperti viskositas kinematik-nya berkurang 50% dan nilai Total Acid Number melebihi batas ( > 7 mgKOH/g). Namun pengguna sepeda motor pada umumnya hanya berpedoman pada jarak tempuh sepeda motor (2500 – 3000) km baru akan mengganti oli sepeda motor-nya, padahal hal tersebut belum tentu relevan.
Pada tugas akhir kali ini akan dilakukan pengujian parameter umur pakai pada oli Yamalube Matic SAE 20W-40 yaitu pengujian viskositas kinematik dan juga Total Acid Number (TAN). Sample oli yang diuji memiliki variasi jarak tempuh sepeda motor 0 km, 2500 km, dan 3000 km.
Dari hasil pengujian viskositas kinematik kita dapat mengetahui bahwa oli baru Yamalube Matic SAE 20W-40 mempunyai viskositas kinematik sebesar 133,61 cSt dan semakin turun nilainya seiring dengan bertambahnya jarak tempuh dimana pada jarak tempuh 2500 km viskositas kinematiknya turun menjadi 87,98 cSt, dan pada jarak tempuh 3000 km viskositas kinematiknya kembali turun menjadi 78,85 cSt.
Untuk hasil pengujian pada oli Yamalube Matic SAE 20W-40 dapat kita ketahui bahwa nilai TAN oli baru sebesar 0,07 mgKOH/g dan semakin naik nilainya seiring bertambahnya jarak tempuh dimana pada jarak tempuh 2500 km nilai TAN meningkat menjadi 2,44 mgKOH/g dan pada jarak tempuh 3000 km nilai TAN-nya kembali naik menjadi 2,89 mgKOH/g.
Umur pakai oli Yamalube Matic SAE 20W-40 berdasarkan viskositas kinematiknya belum berkurang 50% pada jarak tempuh 2500-3000 km dan baru berkurang 50 % pada jarak tempuh 3660 km (berdasarkan perhitungan ekstrapolasi).
Umur pakai oli Yamalube Matic SAE 20W-40 berdasarkan Total Acid Number belum melebihi batas 7 mgKOH/g pada jarak tempuh 2500-3000 km dan baru melebihi batas pada jarak tempuh 7577 km (berdasarkan perhitungan ekstrapolasi).

Many factors that affecting to the age wear of oil on motorcycle such as the kinematic viscosity are reduced by 50% from the fresh oil and the Total Acid Numbers exceed the limit (> 7 mgKOH / g). However, motorcycle users are generally only guided by the distance of motorcycle (2500 - 3000) km then change their motorcycle oil, but it is not necessarily relevant.
In this final project will be testing the age wear parameters on Yamalube Matic oil SAE 20W-40 which is testing the Kinematic Viscosity and also Total Acid Number. Oil samples tested have variations of motorcycle distance at 0 km, 2500 km, and 3000 km.
From the results of kinematic viscosity testing we can know that the new Yamalube Matic oil SAE 20W-40 has kinematic viscosity of 133.61 cSt and further decreases in value along with the distance traveled where at 2500 km distance the kinematic viscosity decreases to 87.98 cSt, and at the distance of 3000 km kinematic viscosity decreases again up to 78.85 cSt.
For TAN test results on Yamalube Matic oil SAE 20W-40 we can know that the new oil have TAN value 0.07 mgKOH/g and further increases in value along with the distance traveled where at 2500 km TAN value increases to 2.44 mgKOH/g and at the distance of 3000 km its TAN value increases again up to 2.89 mgKOH/g.
Yamalube Matic oil SAE 20W-40 age wear based on its kinematic viscosity has not decreased 50% at 2500-3000 km distance. And only reduced 50% at 3660 km distance (based on extrapolation calculations).
The age wear of Yamalube Matic SAE 20W-40 oil based on Total Acid Number has not exceeded the limit ( >7 mgKOH/g ) at 2500-3000 km distance and only exceeds the limit at 7577 km distance (based on extrapolation calculation).
