  1. hunky boss as your saying that motul is good for RTRs but according to spec its 20w40 so did you have tested on any RTR as me also confuse a bit

  2. HUNKY – correct me if i am wrong – 15w 50 means max 15 degree lower & max 50 degree higher but many says that we should not exceed more than 40 i.e., 20w40 & moreover 15w50 is more viscous that 20w40 so initially will it effect the pick up of the bike ??

  3. we dont find motul 5100 here in dgp but yamalube is available …
    can we use them in 220 ‘s … and apache 180 …

    • I have shown and written brother, the difference, you can certainly use but performance / feel wise, they are different..

    • Motul 300v 15w50 -> Rs. 895/- (printed)
      Motul 7100 20w50 -> Rs, 725/- (printed)..

      This article is about showing the difference in similar two product, the Motul 5100 15w50 (semi synth) and YamaLube 15w50 (semi synth).

      300v and 7100 is completely two different product from 5100 or YamaLube by the way..

  5. Hunky bro… here is an information
    The recommended engine oil grade for Pulsar 150 UG4.5 is 20w50 not 20w40. It is written in the owner’s manual.

    What engine oil is better used for YBR125?

    • Here in India this 125cc motor is used for commuter segment product.

      For commuting need, the YamaLube 20w40 mineral engine oil @ INR 225 would suffice where as if some one wishes to use this motor for any other reason, YamaLube (semi Synth) 15w50 @ INR 415 would be best.

      Thanks..

    Hello guys! The 15W50, stands for viscosity and W stands for winter. So, what it really means- the oil is light enough to let the engine start- up in the morning easily but thick enough to withstand high temperatures. Today’s semi synthetic oil are very sophisticated able to coupe wide temp requirements. I don’t think the comparison above justifies the two oil. What many people forgets the manufacturer recommended viscosity, if Bajaj recommends 20W50, so switching to 10w30 will feel very light in the begenning, but after some tme a certain amount of roughness comes if anyone observes closely. So, one should stick to the manufacturer’s recommended viscosity(it doesn’t mean one should use only mineral). The mineral oil is used when the engine is in its running-in period, but d’nt switch to semi synth or synth after first servicing. At least run for 8k to 10k km on mineral. This recommendation is made by Castrol R&D, after many years of testing on engines. Depending upon different riders, the engine conditions, type of engine(liquid or air cooled), the difference upon using different brands of oil will vary. If anyone wants to know which oil is best then go on use all of them one after another, but stick to the stock visosity as much as possible, you will find which oil your bike loves(. Trust me, you will not blow up your engine(i, am a mech engineer, internal combustn engines is my specializatn). And last about synthetic oil, they are the best. These oils are generally use if any one goes to racing, goes to track much of the time etc etc. Any one can use it, after the proper run-in period, but it is best utilized for demanding engine applications(racing). A normal everyday commuting will not benefit much. So choose properly and your machine will shine!

      Hi,
      5100 4T is a much superior product over Yamalube semi synth 15w50. 5100 is a ester powered with FLS 14 gear rating , hence much superior in performance . Now we get even 5100 4T 10w30 specially for Honda, Hero, Suzuki and TVS bikes.
