Redline 10w60 or LiqiMoly?

Thanks for all the input guys, thinking of picking up 3 qts of their 5w40 to thin it out, as suggested. 6:3 10w60:5w40 seem ok? It gets hot here in NC and under spirited driving I'd like to have that piece of mind.

That averages out to 5.33 HTHS (fresh oil)

I have questions with "blending" oils of different viscosity.

I blended Redline 10w60 and 0w40 (7:2) this time. Prior to this, I used BMW TPT 10w60 which saw ~1L consumption in 1500km.

So far my oil consumption is reduced to ~400ml per 3,000km including two track days, one at Okayama international (30 full out laps with some traffic). You can see that oil consumption is noticeably reduced, all conditions except oil filler cap (changed to E46 M3) stayed equal.

My questions are:

1. I would have to say oil viscosity is proportional to oil consumption in our engines. Would it be the case that fluid of 0w40 kinematic viscosity inside the total fluid is the main culprit in oil consumption?

2. I would have to assume oil viscosity of 0w40 and 10w60 achieve their grades with different properties. Does averaging kinematic viscosity work with evenly blending oil properties?

A thicker oil alone may not be the primary reason for reduced consumption. It is a big part of it, but not all of it. Red Line and the BMW/Shell oil have very different chemistries and additive packages. Every engine and driver are different so sometimes you need to experiment to see what works best. If you've found a combination that can maintain oil pressure while reducing consumption, then stick with it -- but that exact blend may yield different results for another owner.

You can estimate the new viscosity with simple algebra, yes, but that's not going to be perfect due to standard manufacturing variances. The spec sheets are just showing you the approximate viscosity/specs, not the actual. Send in a sample of brand new oil to be tested -- it will not match the spec sheet exactly. I have seen viscosities off by as much as 10% and additives off by just as much.

I only use 10w 60 liqui moly or motul 10w 60. While pressing the car hard it very seldom moves over the half way mark. Under normal driving in power mode the temps is at 3/4

Vous vous demandez si les gens utilisent encore 10w60 Redline ou une autre marque?

J'ai commencé ce thread il y a deux ans lol!

Je suis récemment nouveau dans le monde e9x, j'ai lu, ce sont des huiles qui vous donnent moins de bruit.

Avez-vous des commentaires sur CASTROL 10W60?

Castrol est l’huile secondaire de cette voiture, alors oui, Castrol 10w60 est un excellent choix. Il est passé par différents noms et versions, mais actuellement, je pense qu'il est appelé voiture Euro, et vous verrez il recommandé pour BMW M et d'autres comme Audi R8

Mon 2 [propriétaire d'origine 08 & 12 e92 M3s]...
Ran a recommandé BMW Castrol [diverses versions de marque] exclusivement ~ 8 ans.
Opté pour LM en 12 M3 à partir de 2016.

• Dans certaines conditions, comme par démarrage à froid, différence quelque peu détectable par rapport à Castrol. En dehors de cela, pas grand chose une fois à temps.
• Couvercles de vanne - - commuté à l'alliage NRW AL vs magnésium OE > VT 'bruit' un peu plus perceptible des OE.

IMO, une légère augmentation du son mécanique audible, en particulier avec les couvertures AL... bien par moi, tant que pas de performance ou d'autres dégradations mécaniques.

Je n'ai jamais essayé Redline. A ma connaissance, LM ne présente aucun risque apparent... bien sûr, les opinions et YMMV

La ligne rouge qui est devenue populaire à utiliser (toujours?) avec s65 / s85 est 5w50 de Redline et non 10w60. Redline est une huile de course. Ils sont plus viscocité que d'autres marques dans la même note comme 10w60.

C'est exagéré.
