Yes. If you have a high compression engine you may need higher octane fuel, but generally most of todays vehicles don't need a higher octane fuel because everybody is trying to reduce Nitrous emissions and have lower compression. Always buy fuel at a place that sells a lot, and use the fuel that sells the most... typically regular. Using "fresh" fuel helps keep the injectors clean.
You can use Mobil 1 synthetic power steering fluid for a 1999 BMW 528i.
use key to manually unlock. manual unlock will not work.
A; A Synthetic oil is reccomended for most/all BMW's. (which brand is up to you) The owner's manual will usually give you the best answer, however, in the older (1998-2000) 528i series it is Mobil 1 0W-40. It is also referred to as the European Blend.
Regular atf fluid will do something good thoughlike penzoil atf pt#3312 will do
Automatic Transmission Fluid /Dexron III or higher. DO NOT use Pentosin in this model. If you do you will eventually regret it.
BMW only takes gas rated at octane 91 or higher, and that is Premium at the gas station.
cheap gas
The BMW 323 i takes Premium gas,but can use mid grade as well. premium is preferred.
BMW always recommends using 98 RON petrol (gas). Which is premium unleaded.
Castrol TWS 15-40W. Not cheap but that's what mine came with.
