Today, the Liqui Moly 20W - 50 4T covered a mileage of 1200kms in my Sprinter. You can see the snap below for its condition at 1200 kms running.
Physically, the oil is still fresh and viscous. I also asked my mechanic to check oil condition and he was quite surprise by the quality of this oil even after 1200kms running. He was simply not hesitant in saying that you can easily and safely (with no risk) stretch this oil till 2000 or 2500 kms. Though the oil dealer claimed 4000kms but I am NOT taking the risk as per our traffic conditions.
There are some other factors for me in getting this good conditioned oil. My Sprinter engine is cleaned Ma sha Allah say so it always used to give me oil in this color when I was changing the Castrol Active at 1000kms mark. Secondly Sprinter has oil filter so definitely it is cleaning the oil.
My other PW fellows who are using LM, I would like to tell them please do not fully rely on my feedback. You should also provide your feedback especially one who owns bike withOUT oil filter like Honda or bikes with older engines.
In the end, I have no issue in changing this oil at 2000 kms mark because then it will fully justified its price. 2000km @ 700Rs-(LM oil) is very much equal to 2000kms @ 570(260+260)Rs (Castrol Active).
And its not just the price. With LM (even after 1200kms) you are getting a smooth, sound, vibration less ride. Soft gear shifting, no engine tiredness on long routes, no heating issue, greater pick, more fuel efficiency (I've observed extra 2-3 kms running per liter) , greater engine protection. And I think this is certainly not a 'Ghatay ka soda'.
Again, the above is an honest feedback withOUT any exaggeration. I will be getting my second LM bottle soon because I'm very happy and I have no issue in spending 700Rs when I can get oils in just 260Rs.
