For starters why did you put 5W20 in that engine? Because one person on the internet liked it? Drain the sump and re-fill it with the specified grade of oil and keep your fingers crossed.

I would grudgingly agree with a 10w-40 HM (i.e. MaxLife) and stick with it for the time being. I like MaxLife, I don't like 10w-40 much, though. wink Run a couple short OCIs on this and monitor things.

Depending on the temperature, 5W-20 may be specified for that engine, same as my E34 M60.

I`m very sorry to hear about your grandfather :^(


thanks about my grandfather, i'll get by .. 20w50 isn't too much? i have 10w40 5quart jugs already but honestly they were 15 bucks.. i'd get the clearance just just to have on hand.. thanks for the heads up

you may be right, there's a lot of conflicting information out there because of those nikasil lined blocks.. specs changed over time.. i am friendly with a bmw mastertech that opened an independent shop and he actually said that they changed the spec on the spark plugs at some point and i should switch to 4 prong plugs instead of the 2 prong plugs they originally came with.. i dont have part numbers on hand but i can get them if you want.. i have the 94 530i as well with the 5-speed.. i love the car..

He should check and see for sure then, because of changes to the spec etc as already mentioned. If it is he should still drain the sump and rid it of the two additives he added to his oil which might have taken it out of grade.
