Unusual Liqui Moly Leichtlauf HT 5W-40 behavior
- Thread starter slo town
- Start date
That's why I like the good ol' dipstick. Never trust electronic gadgets in exess, sometimes they even can lie to you that your car has burnt 2/3 to 3/4 quart of oil in 128(!) miles. I really think the measurement of the oil level was not correct, an engine really capable of burning this amount of oil in 128 miles (whatever the oil is) must have some serious problem, I'm sure this is not the case.
Regarding Liqui Moly oils - I've always found them quite overprised and indeed nothing special, although I have much respect and very positive results with their oil additives. I'm sure german Castrol 0W-40 or Mobil1 0W-40 wouldn't be wose, maybe even slightly better than LM, which by the other hand absolutely doesn't mean LM oils are so bad to desappear by quarts in 128 miles, I doubt there is such a bad oil available nowadays.

As for LM, their main selling point is that they are Made in Germany. Bunch of other better oils on the market Made in Germany or not.

It is strange what he is saying, but again, since I had exhaustive experience with LM, I can only rate them as average at best. When I used LM due to flooding of fake M1, Castrol etc. in Central Europe, my cars burned LM like crazy.

Hello all, OP here. I've been off the grid for awhile.
Various follow-on comments:
1) I noticed this rapid oil loss after an oil change on both my E46 and my wife's E90.
2) The NOACK spec ASTM D5800. Evaporation loss is 1 hour at 250 C with air blowing across it.
3) The LM oil was bought from both Pelican Parts and RM European - both legitimate sources.
Aide from a very small initial top off of about 1/8 quart (now using German Castrol 0W-40), neither of the cars use any measurable oil. The E90 has about 3,500 miles on GC, and the oil level is still at 100%. The dipstick on my E46 shows 100% full, though I've only put about 600 miles on it since its GC oil change.
What I've seen......with fresh oil LM has a greater initial evaporation loss than does GC. After this initial evaporation loss, both oils "stabilize" and go the rest of the OCI without any measurable consumption.

At that rate of loss, I'm thinking "Where did the oil go??"
Did you notice blue smoke, dripping around cam covers, emissions lights on, anything? The cars look super tight so I think it is very strange. Could you have had some odd air bubble effect somehow that would trick you into believing the sump was filled 100% when it wasn't? (Had that but in a marine drive, but that is known to happen.)
FWIW I've been using Leichlauf HT 5W40 o my 2008 MB E350 4Matic 5Km a year for 2 years without any consumption. Actual Km 53,450
Used mobil 1 before and also tried 0W40 which my car did not like on start up, it prefers 5W40
Liqui Moly Leichtlauf 5w-40 VOA
Liqui Moly Synthoil Premium 5w-40 VOA, I was considering either of these Liqui Moly Oils for the summer, after these results I'm staying with my Castrol 0w-40
"Evaporation loss (Noack) 10,0 %
CEC-L-40-A-93"
From https://pim.liqui-moly.de/pidoc/P000330/3863-LeichtlaufHighTech5W-40-33.0-en.pdf
Seems like a feature of this oil.
Not sure what to make of the OP's plight. I've used LM HT in all 10 (yes) of my GTIs, including 4 MK7s, and none of them have used a drop of oil much less exhibit what the OP reports.

Hello:
I am the OP of this thread. I have attached a VOA and UOA for Liqui Moly Leichlauf HT 5W-40. The are my own personal oil analysis reports.
The UOA is when the oil only had 150 miles on it! Look how it thickened! cSt Viscosity @ 100C increased from 13.82 to 15.08. In just 150 miles! Given the amount of evaporative vapors I saw through the oil filler hole, compared to "German" Castrol, it is no surprise.
IMO, this particular version of this oil manufactured around this time is junk. What I have left is part of my "armageddon stash". I would not use it in any of the vehicles I now own.
