Recommended engine oil for E34 with M50?

[Rick L]

This is my first oil change on my first BMW. What type and weight oil is recommended on 1995 BMW 525i with 74k miles? Is Mobile 1 (0W-40) oil work well with this engine? On the container, it said it was recommended for BMW. Second question, what is “0W” on 0W-40 oil? I realize “40” means the weight but what is “0W” stand for? Is “0W” recommended?

Thanks,
Rick

OW is what the oil viscosity at freezing temperature. Stick with basic oil... Mobil 1 10W30 that you can buy anywhere... for $4 a quart.

i use mobil-1 5w30. been thinking about switching to 0w40.

0w is the weight of the oil when it is cold. the thinner oil will lube your engine faster during cold starts.

I have the same car and I use 5W30. Works great for me. 186000kms later, my car is running smooth as ever.

5w 30 all weather all around kind of juice...Id try the 0w-40 but its unobtaniable here and probably exempt. whatever as long as you dont go over 40 wt with a full synthetic is good.

If Mobil 1 0w40 isn't basic, then neither is Mobil 1 10w30.

Why not go to 50W with an engine with over 100,000 miles? I always thought that it gave better protection especially during the summer. Is there something I am missing?

10W40 for the winter and 20W50 for the summer, for high-mileage engines like mine (184,000).

Oil easily attainable at local stores... Where do you get Mobil 1 0W40? I only know MB or BMW sells them for like $9 a quart
