Does anyone use Liqui Moly here? Considering between 5w30 Top Tec and 5w30 Molygen - read a few articles but confused by the mumbo jumbo!

For liqui moly you're likely going to need the Top Tec since it has the BMW LL04 approval. I think Molygen might last a little longer but seems like it hasn't been approved for the LL04 yet, better not risk it!

Thanks for the reply, didnt know Molygen was not LL04 approved. How about the viscosity? I wanted to go for the 0w30 but ML Performance recommended me the below 5w30 instead.

These chaps are even cheaper than Amazon and ebay so a bit hesitant, have you got any experience with them?

LL-04 is meant for diesels. LL-01 and LL-01FE are the gasoline specs. With that said, anything with the Porsche A40 approval is perfectly fine for our cars, don't get caught up on running the BMW approved oil, especially if you are not going by the oil life monitor and doing extended oil change intervals.

I’ve been using the Molygen since it came out, so I guess 3 or 4 years. I had a blackstone analysis done every change for the first couple years at around 8k intervals, so like 4 reports over 2 years. They were all good and Blackstone kept telling me to push the intervals longer to 10k because the oil was fine. Molygen is LL01 certified btw.

That said, I would not get hung up on the LL01 as much as the change intervals personally. The LL01 is to have those annual 12k or more changes, not because oils without the spec will wreck your engine. Like Mobile 1 used to be LL01 and then stopped that certificate about 4 years ago. It’s still an amazing oil which Porsche uses in their GT3, GT2, etc. I doubt that Porsche is putting crappy oil in their track spec 9000rpms $200k cars.

Keep up with your changes, and if you want to try the 12-14k mile intervals then I would say definitely look at a LL01 oil.

123k mile N52 5w30 Liquid Moly LL01. Oil change intervals every 4-5k. Car is almost silent on this oil. You can't go wrong with liquid moly...

Another vote vote for 'Moly. Isn't that what the kids call it? 5w30 in the Bimmers, and 5w40 in our Benz. All running around 10k mile intervals with Blackstone analysis. I change filters and top off mid-interval because that makes me feel good inside.

Isn't the LL04 meant for both diesel and petrol engines?

The lads at ML Performance who distribute Liqui Moly over here replied to me:

'The Top Tec is suitable for gasoline and diesel engines that meet the Euro 4, Euro 5 and Euro 6 emission standards. It has BMW Longlife-04 approval and Liqui Moly also recommends it for the BMW Longlife-01'

P.S. I am in the UK not sure if that makes a difference

Is this the Liqui Moly Molygen you are referring to? I cannot seem to find anywhere that states it is LL01 certified?

https://products.liqui-moly.com/moly...n-5w-30-1.html

Nor here?

Or am I looking at the wrong product?

Yeah have only heard good things about it really - how about Cera Tec have you lot tried it before too?

Thanks for the reply, regular changes defo sound essential!

[whyzee125]

I personally don't use Liqui Moly but I've heard great things about it and the only indy in my area that I trust swears by it. I'm sure you'll love it, whichever line you go with.

Viscosity wise I personally don't think there's much difference between the two, I'd just go for the 5w30. The only difference is that 0w30 flows slightly better on very cold mornings I believe.

I think the confusion comes as there are different requirements here in the UK? From my understanding I believe LL04 oils can be used on petrol cars in central europe due to the different fuel quality. But for other countries, you'll have to stick with LL01 if you run petrol. LL04 can only be used on diesel cars outside of central europe.

It is the correct product but wrong viscosity. 5w40 is the LL01 approved oil. If you read the label at the bottom it says it’s approved:

I switched to molygen when Rowe was no longer available from FCP Euro. It feels like every other oil I've used: there's no tangible difference. The only way I'd know is thorough an oil test, and I just don't care enough to do one.

...

In Europe stick with LL04 (for extended OCI).
LL01 is for NA due to high-sulfur petrol.
If you are on shorter OCI's (4-5K) LL-certified oils are not needed.

+1 for Liqui-moly. The car doesn't notice the difference between it and any other spec'd oil and neither do I. At the price of free in the US, it can't be beat.

Ahh thanks for the clarification - 5w40 Molygen indeed has the LL01 approval! I guess the only difference is the viscosity but from what I gather based on the replies here that doesn't matter too much as long as the approval is there.

So might give this a go!

Yeah, thanks for the advice - I think it mainly stems from UK vs US definitions!!

Funnily enough after you said this YouTube recommended me this. It's getting a bit too smart for my liking!

The oil meets Bmw's LL-01 requirements, however it is not approved by BMW.

Nowhere on the bottle does it say it is approved.
They have to pay alot of money to Bmw in order to have that designation.

Many make this mistake when they see the label.

It is still great oil, and you can't go wrong with it.

The 0 or 5w makes zero difference in UK climate really, but I'd go for the 5w if everything else was equal.

Ll-04 or -01 will do fine, since it's a petrol it's going in, but neither is necessary.

Changing oil at ~5k intervals is pouring away money, but each to their own!
