Engine oil IDEMITSU or OEM BMW

Idemitsu zepro eco medalist advanced moly 0w-20. Basically the same thing as Mazda's oil.

You don't need to add any more additives to modern day oils. You said you will be using Mazda 0W-20 oil? This is one of the best 0W-20 oils on the market. It is made by Idemitsu for Mazda. It has very high Viscosity Index of 221. Most 0W-20 oils are around 170. This means it is one of the lightest 0W-20 at start up. This is what you want in the winter.

Looks to be exact same procedure as on my e46. Perhaps the easiest oil change I've ever done. In fact, I've used the same brand and spec oil too, which is an BMW LL-01.

Based on extensive testing, BMW has approved only certain engine oils. Use only approved "BMW High Performance Synthetic Oil." If you are unable to obtain "BMW High Performance Synthetic Oil," you can add small amounts of synthetic oil in between oil changes.
