Best Oil for our N55 Turbo Motors?
I'm sure this is an old subject, but I'm new to this (turbo) engine platform and was wondering what everyone else is using for the "Life Blood" of their engine? I strongly feel engine oil is just that, the "Life Blood" of your motor. I've read a lot of different things about addatives in various different engine oils being good and or bad for the turbo. I'm sure BMW oil is good enough, but there's Always something better. I've been thinking Motul or Liqui Moly, possibly even Red Line. Any input and advice would be greatly appreciated. Thanks in advance...

Yes, this topic has been beaten to death. Feel free to search for the other threads with regards to people's preferences / experience with various particular brands.
In quick summary - anything that is BMW LL-01 is acceptable. And no, there is nothing wrong with running the dealership's oil. Do oil / filter changes more frequently than the once a year recommended by BMW and you should be fine. Personnally, I just changed the oil for my 335i xdrive and put in Castrol 0W-40 European formula because it's in stock and regularily goes on sale. It is LL-01. |

I used a k&n filter and the included o ring was not the right dimensions and it leaked oil all over my engine bay. So now I use the BMW filter so I use the BMW oil with it. I used Mobil 1 Euro car 0-40w previously.

Just buy the dealer oil, it's cheaper, it's a shell gas-to-liquid product and very good stuff.

That's a first I've heard of that happening, but I too buy the filter from my stealership. They give me a 20% discount too so winner winner chicken dinner

Castrol 0w 40 or Mobile 0w 40 at Walmart for $23 for 5qt jug. Don't waste time & money on this topic. Anything fancy will have placebo affect on your mind.

In general two factors are important:
Viscosity and Quality (BMW allowance) Quote:
Quote:
0W to a 5W cold viscosity and 30 to 40 hot viscosity is not a big of a difference. (compared to a 0W-30 to a 0W-60) BMW Longlife-01 and BMW Longlife-01 FE certification is important as other oils not having this lable could ruin the engine. (different or missing chemical additives) Above quoted text from the owner's manual http://dn1.bmwsections.com/dl.php?li.../2013_3s_s.zip Hope I got it right..

Smoother idle, smoother engine. I've noticed a significant better running engine going from 5w-30 to 5w-40. |

I just did oil change yesterday and I've been using Mobil 1 0w-40 for the last 10 years.
I just changed to Castrol 0w-40 because the M1 is no longer approved for BMW LL-01. Agreed to purchase from Walmart! |

BMW seems to be using 0w-30 & 5w-30 in our free maintenance, considering buying 5w-40 for the summer heat months

What over meets BMW specs if you are in warranty. If you are out of warranty just get any reputable brand that's the appropriate weight.
Like others have mentioned, Castro and Mobil 1 for ~25 a 5qt jug at Walmart are great. Mobil runs rebates pretty often that drop the price per jug to ~15.

First the 5w-40 has a higher viscosity as the 5w-30. Which means the 40 Oil is thicker compared to the 30 Oil. At the same oil temperature the engine needs more power to run with a SAE40 Oil than with a SAE30 Oil. http://articles.sae.org/11945/ So what you write makes no sense to me.

The N55 is a high performance engine that runs hot. In the US, I regard the 40 a minimum, and higher if tracking. Some manufacturers make an LL-01 5W-40, and, as of 2019, Liqui Moly now makes 0W-40 synthetic LL-01, which I am trying to get as we speak. Shell's Platinum Euro version (repackaged as Penzoil) makes LL-01. Very specific oil batches exist, for example, for 1980s/1990s oil-cooled race cars that require one oil change per 30-50 lap weekend or 5,000 km intervals other wise. The specialists say that, under no circumstance one should use oil not meeting the key manufacturer checklist: SAE approval, viscosity and LL-type specifics. The certification process these products go through are very extensive, everything down to the last polymer is analyzed in labs and then actual kinematic testing in test engines. When certified the product sheet will say BMW LL-01 approved. LL-04 is for diesels, different chemicals, not for petrol engines. If a product does not have the BMW approval even though another grade from that same company does, it means that the company has not bothered certifying it OR the manufacturer has not approved it, i.e. it failed testing. Brand wise, BMW switched from Castrol to Shell (Penzoil in NA). That aside, from Autobahn to race tracks, everyone using French Total swears by it as besting Shell/Castrol and being largely superior to Motul. Total Quartz 9000, made in Montreal, would be the latest LL-01 iteration, with a new 5W-30 just launched February 2018: http://blogtotal.ca/en/products/tota...-20-and-5w-30/ Which one is the best? I used Total through winters- pure coincidence. Summer 2019 will do Total. Presently, Liqui Molly is the best transformative engine 'feel' experience. BlackStone confirmed no engine issues.
