The triple synthetic formula of Mobil 1 fully synthetic lubricant series is "PAO + EHC oil with hydroisomerization MSDW technology (Group III+ base oil) + alkyl naphthalene + tricyclic "Molybdenum additive" is now gradually changed to "EHC oil with hydroisomerization MSDW technology (Group III+ base oil) + PAO + ultra-high viscosity PAO + ester + alkyl naphthalene". In fact, ultra-high viscosity PAO is the "Supersyn" on the packaging. This is Mobil's unique patent and registered trademark. Mobil 1 performs very well when the car is hot, and the noise is very low whether it is idling or cruising. Mobil 1 engine oil (Mobil 1) generally starts to make noise when the speed exceeds 4500rpm/min, because above this speed, it provides It is not only the base oil that protects the engine, but also the support of additives. Although Shell's factory in Arizona, USA, also produces PAO, it is only PAO4 grade. PAO's oil and oil film are relatively thin, so its noise reduction ability is average, but it can provide an excellent oil film at high temperatures and good high temperature resistance, so you don't have to worry about its lubrication and protection capabilities.
