Bought a 2014 535i, I've done downpipe and charge pipe. I'm about to do a MHD tune. What I'd like to know is, do any of you add Liqui Moly Cera Tec to your engine when you change the oil or just do the oil without additives.
I wasn't able to find anything in a search.

If you're already Using Liqui Moly as your Engine oil, I've been reading from other Members in different Series in the forums, there isn't significant benefit if you are using the Liqui Moly Engine oil Combined with the Ceratec, (More so with Molygen) I thought of it too, I have not used Ceratec, which states increased film protection and reduces engine friction and states it can improve fuel economy, should you use it, you really don't have to use it every oil change, unless you were using lower quality oil, BMW User manual says do not use additives. Just use a Top quality Oil IMO and change it more often around 3-5k Miles, with your tune, you'll be golden. Save your money for the better oil as the oil will have the additives and more than what you need for your N55. Since I owned my car, I did one Engine flush, and my oil changes have so far been only using Liqui moly Engine oil. Once the Engine is nice and warmies, open up the throttle and start the boost on that Borg Warner Twin Scroll and feel Adrenaline and the stomach butterflies, gets me everytime.

I used a Liqui Moly engine flush and used 5w30 European formula Castrol Edge for my first oil change a couple days ago. I'm just wondering if I should add the additive to this oil.

[ChiltiCoatl89]

I would suggest on your next Oil change, so you can balance the differences! it won't hurt to try it if you use the Castrol Oil on your next interval. Or use the Molygen next time.

[Dsr30]

Rgr. I've got 5W40 Castrol for the next change and I'll add it to that. I'll look into Liqui Moly oil also.

Do you use Mann oil filters?

I use Ceratec every change

I use a 0w40 Liqui Moly due to my area below freezing temps and my car being mostly kept outside in those temperatures in the winter. Nice cold start protection. a little pricy however very worth it.

If freezing is your concern, you should be fine using the recommended viscosity for the N55 engine which is 0W-30. Pour point of this oil is -49F which is low enough. In fact there is no difference in the pour point of the 0W-30 or the 0W-40 Liqui Moly.

I switched to Special Tec LL SAE 5W-30 #LM2249 / 5 liters, with the BMW Linglife -01 after reading this post. You can find entire conversation on this link

How does this compare to the 0w40 in hot climates?

Normal operating temperature for a gasoline engine is between 195 and 220 degrees Fahrenheit. Almost all automotive engine oils are blended to provide protection to an engine within that operating range.

If you notice the viscosity index of this oil is very high (its ability to withstand the change in viscosities between extreme temperatures).

My suggestion: Always stick to OEM recommendation, no matter what you read on the internet. They have designed the engine and they know what is best for it.

This is coming from a guy who has spent 26 years at Shell & BP.

I use the LM Cera Tec once every third oil change. Also, I use Castrol Edge 5W-30 Advanced Full Synthetic. I buy a bunch and just bought a bunch on Amazon Prime Day, $19 for 5 qts. I've never had oil related issues, but I think that it's more due to more to oil change intervals, I never go past 5K miles. My $.02.

I've been using LM 5W40 Molygen for years now and never looked back. No need to add ceratec to this oil since the Molygen oil already has the "molyblen" (I know i have the name wrong but it's the primary additive of Ceratec) in its formulation. LM themselves say to not add Ceratec IF you run their Molygen oil for this reason.

I use this oil year-round from summers that get as high as 112*F and winters as cold as -5*F. Never had an issue with it. :-)
