Meinasin linkata tänne myös tuon okkimin laittaman öljysepostuksen, siinä on paljon lukemisen arvoista asiaa. Ehdottomasti joku suositeltujen viskositeettien mukainen laadukas öljy koneeseen. Esim. magnatec tai edge. Itse olen vatkannut bitukalla edge 0W-40 öljyjä, kun sitä saa saksasta kotiin kannettuna kohtuulliseen hintaan.

Miksi Castrol listaa tuolla AGB/AZB koneille 10W-60? Ei ole kyllä ensimmäinen kerta, kun nuo suositukset aiheuttaa henkilökohtaista ihmetystä.
Miksi 40 on parempaa kun 50? Lukekaa tuo opien pdf; The thicker the oil is the more friction and drag and the more power the engine needs to move it around the engine which inevitablytranslates to less at the wheels. The thicker viscosity oils lead to a slower oil flow rate, which can lead to several problems. There can be localised high oil pressures in the engine, causing increased
wear at certain points as the oilways are not designed to cope with the thicker oil. One of the main functions of the oil is to carry heat awayfrom the engine and that is then cooled bythe air flow over the sump – with the thicker oil the flow rate is slower, meaning less heat is taken away and higher oil temperatures occur (that can also lead to people thinking they need thicker oils). In a worst case scenario with thick oils (when not required) is that you will experience air entrainment and cavitation inside the bearings at high RPM. Not clever stuff!
