Motul 5100 – 15W50: Reviewed and Tested
Just a week ago I had done engine overhaul of my motorbike. I own a Hero Honda Karizma 2003 model. 85000kms old.
After changing all the engine parts my mechanic delivered me the bike and it was running on the standard Hero Honda 10W30 oil.
Just to free the engine I decided to ride first 2000kms under speed of 60kmph.
I wanted to know if now after all the engine work the motorbike is consuming/ burning or turning the oil black before 2000kms.
The first 500kms the engine was turning hot very quickly but I presume it happens so for the first time for the piston and the rings to get adjusted.
By the time odometer reached 550kms I checked the dip stick and found out the oil level was low. And after draining the oil, it was 300ml less and burned. Totally black.
It had me worried but I bought this Motul 5100 semi synthetic oil – Grade 15W50 recommend to me by friend Gaurav.
After it got completely blended in the engine I started making test runs every day for 100kms.
In just 5 days when I checked the dip stick at 500kms with my fingers crossed I saw the oil level is not only full but even the color is still golden 
…
Then later after 15 days I reached the mark of 1800kms and again I checked and result was same. Oil is still full and golden.
Motul, is a well know brand in performance bike engine lubricants. It has the semi synthetic technology and very suitable for 4 stroke engines. For Indian conditions it is the best. Also look for the title ester on the can which makes it suitable for the engines with require simultaneous lubrication.
The gear box becomes smooth, reduced noise and efficient wet clutch plates guarantee. The drain period company says is 5000kms.
So I say use this oil on new / old engine without hesitation. Its cost around Rs. 435 but I heard recently the price is coming down to Rs. 350. Trust me its better than full synthetic oil. Runs good in cold and hot weather conditions.
