Yes Nabeel bhai LM is LM indeed.
Yes Ceratec is an oil additive.
From LM webiste :
"Cera Tec is a high-tech ceramic wear protection and can be mixed with all commercially available oils. Cera Tec reduces friction and wear by using chemically and thermally extremely high-resilient ceramic compounds. Prevents direct metal/metal contact, increasing the service life of the aggregate. The smooth-running effect reduces fuel consumption in gasoline and diesel engines"
as ceratec is of 300Ml so you need to pour 300ml less oil in your car. In my case i decided to put 4.15 litres of oil in my car. So i bought a 4 litre oil pack and took 150 ml out of it. so 3.85 litres of oil and 0.3 litres of ceratec makes 4.15 litre total.
the direction are u need to put both ceratec and oil at the same time or you can also put ceratec after you have poured the oil . I forgot to take the picture while they were pouring , One guy was pouring oil while at same time other was pouring ceratec with it with some delay so that it ensures proper mixing of oil and ceratec.
Ceratec is good for 50000 kms.
