PERBANDINGAN OLI PRIMA XP, SHELL HELIX, DAN PRIMA XP II PADA ENGINE TOYOTA AVANZA DUAL VVT-I 2018 MOBIL --

ABSTRACT
The engine consists of moving metal parts such as the crankshaft, piston rod, and
valve mechanism parts. To avoid direct contact it is necessary to provide a
lubrication system. Lubrication of the engine is very important, because without
lubrication the engine components will experience direct friction, causing heat and
causing damage in the form of wear and tear which ultimately results in the life of
the engine and its components not being durable. Generally, fluid is given between
two moving objects to reduce friction. Disturbances that often occur in the
lubrication system are too low oil pressure, too high oil pressure, wasteful use of
oil, and the oil turning watery. Efforts to prevent damage to the lubrication system
are to carry out maintenance and replacement of lubrication system components on
the engine. Therefore, it is necessary to prove a good lubricant performance. In this
study, an oil comparison test will be carried out on several oil samples, namely XP
primer, shell helix and XP primer ii. Testing is done by turning on the engine to
1000, 1500, 2000 rpm. Then it will be tested in a few minutes and then the results
of the test will be compared and look for which one is more likely to be used on the
2018 Toyota avanza dual vvt-i engine.
