Engine oil for M54B30 in the blazing Middle East?

Hi,

Time to change my oil and need some advice.

Last oil I have used was the Liqui Moly Molygen 5W40.
Should I stick to that? Or should I go for Red Line 15w15?

I currently have a couple of leaks: Main seal and valve cover (again for the third time 14 months).

something "heavy", the reason e46 m3 uses 10w-60 is because it can handle much higher temperatures and won't lose oil pressure. 40w maybe even 10w-60 (up from 30w stock) should b ok tho with high temps, never heard of ppl using 15 -15. Conversely, don't ever try to run 10w-60 in freezing temperatures

If your valve cover gasket is leaking, make sure your valve cover isn't warped. Other than that, only buy a genuine BMW gasket. The aftermarket ones don't last

I have a feeling the valve cover is warped, because that's the only reason which makes sense .. I replaced the gasket with Reinz gaskets, and also the rubber grommets too .. problem is, a new valve cover would be expensive and not worth changing..

Living in Dubai, the lowest temperature we get is around 27 degrees celsius in winter..

So you recommend going for 10w60 in the M54? any disadvantages?

If the cooling system is working correctly, the ambient temperature has little effect on the engine operating temperature. There isn't any special oil requirement for hot weather.

I guess I'll go ahead and seek new OEM VCG..

Any solutions to a potentially warped valve cover?

Never had any engine heating issues, so I believe cooling is fine (The AC not so much on the other hand)
Still on clutch fan as the weather here is too hot for just one electric fan

I've only heard about getting a replacement off ebay or a junkyard but you never know if it'll be warped

Find a M56 valve cover - it is metal but some plumbing will change a bit.


Elring Klinger VCG is what my local indy BMW shop uses - the only one they will use.

I was looking that up but unfortunately the M56 engine was never sold around here so there's no way I can find it in the UAE or this region

Just curious, does the vcg leak at the same spot everytime?

Also, is it losing much oil between changes? Is that why you want a thicker oil?

Yep from the same spot just near the exhaust manifold.

I did almost 5K miles (8000 Kms), I didn't measure how much oil I had to add, but the oil indicator on the dipstick was at minimum and I filled it to full.

Engine oil for M54B30 in the blazing Middle East?

LiquiMoly makes great oil. The base stock is type 4 stock while most “consumer” oil is made of type 3 base stock. The difference is that type 3 base stock is made of Dino oil that’s broken down into small polymer chains. Technically its synthetic. Type 4 base stock is made from man made polymer chains. It’s a true synthetic. Fyi, Redline oil is made from type 5 base stock.

I run LiquiMoly 5W30 in my 2018 M240i even when I track it. Stick with LiquiMoly.

Liqui Moly is top shelf. I would also trust Mobil 1 0W-40. Factory fill for AMG and if you knew what kind of extreme testing those lunatics subject engines to, you'd be comfortable running their oil of choice in any climate.

0w40 is fine. You could run a 5w50 but its not necessary for regular street driving
