    N54 oil preferences

    I have been reading posts on the forum and there was some discussion early about increased turbo wear due to the higher boost levels when tuned.

    I think one way to mitigate some engine wear is to use the best oil possible. I have yet to see a consensus on the forum regarding oil. The Castrol 10w/60 the dealer recommended appears to be pretty good. I use what I consider to be top tier based on past experience, Amsoil 5w/40 which meets BMW's stringent specs.

    Anyone got an opinion as to what works well in the N54? Thanks!

    Who recommends 10w60... this seems way too thick. I always use a 0w-X as start/warm up is the most critical for an engine. I will be installing an upgraded oil cooler and depending on typical temps I may go thinner. Using 0w-40 mobile 1 now.

    It would be good to start logging some oil pressures with different grades. This is a good way to determine what's best. Haven't even looked if its a logable channel or in the hidden menu.

    German 5W-40 currently. Thats what my shop recommended, so i went with it. Never really thought about changing it up. What are the benefits of different weights?

    Mobil 1 0W40 now. Perfect all year around, and even for track duty.

    I've heard good things about the Rotella oil.

    Josh- I agree about the 10w/60. Not only is it hard to find but I think it is a bit thick for the cold weather we have here. I was worried about using thinner oil but so far the level appears to be holding steady after 2k+ miles.

    Turkeybaster, zeal-do you use any oil between changes with the thinner oil?

    if you live in a freezing climate.. go 0w.. if you live near the equator, go 10w, .. mild climate.. 5w.. if you drive street, go -30 or -40 if you drive REALLY hard.. if you track it a bunch, -40 or -50.

    redline oils are great stuff, and a great price, one of the few that are proper base V stock. some of the best you will put in a motor. period.

    anything that's a fully synthetic (base IV and up) will keep the motor fairly happy, but a base V is just that little bit closer to perfect.

    Use Mobil 0W-40 as recommended by BMW. The $#@!ty thing is that they don't sell 5ga jugs so you have to buy like 8qts individual each change.

    Isn't the N54 OEM oil Castrol Edge 5w-30?? Pretty sure "Castrol Edge" is written right on the oil cap

    Yes, quite a bit, but that's probably due more so to my triple digit mileage.

    It just sez bmw recommends castrol. It doesn't specify Edge. 0W-40 is from BMW usa, under warranty requirements.

    The OE stuff is 5w-30 but they also posted the Mobil 1 equivalent that should be used is the 0w-40. I cant remember where.

    Actually, you can buy it in 5.1 quart jugs but not every place carries it. I couldn't find the jugs at my local Walmart but Advance Auto Parts next door had Mobil 1 0W-40 jugs in stock.

    I don't see much oil usage. I've gone about 7k since my last change and added 1/2 quart. That was after a few business trips to upstate NY, PA, OH, and WV as well as 2 trips to the drag strip. I'm changing it at 8k so I'm due.

    I've used Mobil 1 European Car Formula, 0W40, car ran terrific, oil temps were good. Just tried Motul 8100 Xcess and the car runs great, but the oil temps are noticeably higher, probably 10* or so. I'd say stick with Mobile 1 UPC 0W40.

    Synthetic oil clearly but one with the highest flash point you can find. I have used Castrol 5W30 and BMW 5W30 but going to Mobil 1 0W40 with hopes of reducing the carbon build up.

    absolutely nothing will reduce carbon build up. It's inherent in the design (direct injection)

    Mobil 1 0W40... used Castrol 5w30 before.
    Using Mobil 0W40 oil temps are significant (5-10C) lower than before.

    at a guess, the 30 was becoming too thin when it heated up fully, the -40 stays a lot thicker, so it's taking more heat away by being in the same spot a bit longer?
