Liqui Moly Engine Oil

[Grail05]

Which liqui moly oil do u guys use for your engine ive been searching amazon and they have 2 different 10/60...

I believe they're exactly the same, the bottle color was just a small packaging change. There is only one type listed on both the German and US Liqui-Moly website.

Synthoil Race Tech GT1- Liqui Moly

For a car under warranty, no.

For a car out of warranty, I'm sure it would be fine. In my opinion it's nothing special but if you can get it for a good price, then why not? I certainly wouldn't pay more than the OEM oil.

Fortunately, there are plenty of good choices in 10w60, and the M3 will happily cruise along on any of them.

I've used LM 10w60 GT1 Race tech for the past 20k (4 changes).

So far, so good.

Couple notes:
- it does run a touch hotter than Castrol (220* vs. 210* with castrol) when under load
- it seems to use a consume a little more oil (could be silo'd to my car, though) - 1-1.5 liters per oil change

You can get 5L for $40 shipped on Amazon Prime. Buy 2 of them and have the extra liter to top off during the 5k interval.

I've had the exact opposite experience! I run a touch cooler, almost half a needle's width cooler.

I haven't had to top off yet, unlike with Castrol TWS, I would have to top off every 3k-4k miles.

Understandably this has a lot more to do with driving conditions, but just providing my inputs.

It's quite a bit thicker so should run cooler and should lose less oil

Any downside using thicker oil? Also im in california and 95% weather is in 80-90 degrees

Why would thicker run cooler? Thicker = more friction = more heat (also, thicker = more pressure = more heat)

Lower consumption is a definite possibility.

Yes.

Downsides to thicker oil:
1. More heat
2. Increases oil pressure
3. Increased startup wear
4. Motor was not designed to run on it


The rule is: as thin as possible, but as thick as necessary.

I would not go much thicker than TWS/new Shell stuff unless you are seeing hard data that the car is needing more oil pressure or something (in which case, I would ask if something is wrong with the car).

Interesting. It could be that I only ran TWS for the first 5k when I purchased the car and it was during colder months. As soon as it's 60* or above, I'll run maybe a needle width over 210*

This is what I use. And noticed same results. My engine idles quieter too

I will second this as well. Have been using the LM for the past 55K now approaching 95K. Only have to top it off between changes and haven't noticed any increase in temps.

ive been running Liqui Moly for 30k miles on my 2009.

car is solid oil is good. no complaints here.

Yep ^^^ Not exactly apples to apples, but I ran this in my highly modded E46 M3 and noticed the same thing. Longer to heat up, longer to cool down, and elevated oil temps under high rpm operation.

The motor was quieter at idle because the oil was thicker, but as mentioned, that thicker oil takes a second or two longer to reach critical areas at start-up...thereby increasing wear at start-up. Not really a fan of the Liqui Moly.

Agreed that you want to run as thin an oil as possible that still protects under high heat/stress conditions. I think that they're better choices out there than Liqui Moly.
