Oil Consumption
Hello, so I have been using Liqui Moly 4600 5-30 engine oil for a long time on my W166 ML350 Bluetec and it consumes almost no oil. Then I put Shell 5-30 in and it consumed about 25 oz or 700 ml oil in 8000 km. The Shell oil was not in a bottle but in one of those big barrels, so could that make any difference? (which I don't think is the case unless the dealer lied to me). I know the oil consumption is normal, but I did not know Liqui Moly was so much better than Shell. So I was wondering has anyone else experienced this or is it just me?

Some questions come to mind:
- How many miles on the engine?
- Did you check the oil after the change to Shell 5-30? And therefore you actually started with the correct level?
- Do you check oil regularly at each oil change?
- Are they any oil leaks underneath?
- Are their any signs of oil leaks in the engine compartment?

I checked it at the dealership right after the oil change as it should be done and I check my oil regularly
no leaks at all
The weather gets hot where I live so I guess Shell can't handle high temperatures like Liqui Moly? they are both 5-30 though
