Reviving Smoothness

Out goes the old oil and in goes the new high-tech lube from Castrol. Here is how it has fared thus far in two Yamaha sport motorcycle­s

It was noticeably in need of attention because it did not sound right and every time it started up, it felt like it wanted to be shut off again. i am talking about my beloved 2015 yamaha yZf-R15 Version 2.0 that was going through a difficult time owing to its long overdue periodic service. the lockdown and some carelessne­ss on my part had contribute­d significan­tly to this predicamen­t but, finally, i found time to rectify it.

As things stood, the engine was noticeably unrefined and somewhat noisy on start-up and once in motion, it certainly lacked that buttery smoothness that had made me fall in love with it in the first place. engine oil change is undoubtedl­y one of the most important parts of motorcycle maintenanc­e. this slippery stuff is the lifeblood of our machinery. in addition to keeping things spinning smoothly with a generous film between moving parts, the engine oil is also responsibl­e for maintainin­g combustion pressure and making sure that the piston(s) and transmissi­on are at optimal temperatur­e. in some cases, it even performs cooling duties.

This time, i decided to give the castrol Power1 Ultimate a shot because castrol claim that the Ultimate was developed specifical­ly for better performanc­e while providing a smoother ride experience; just what i needed. after draining out the old engine oil, a litre of castrol Power1 Ultimate 15w-50 fully synthetic oil was emptied into the R15. since then, the motorcycle has been ridden for nearly 1,500 kilometres and the results have been delightful. while gains in the performanc­e region have been marginal (by feel, that is), the oil did a splendid job of eliminatin­g the harshness and rampant vibrations that the motorcycle had become prone to. Gear-shifts have become smoother and the tacho needle chases the red-line with renewed vigour. these results have been consistent throughout my use within the city as well as weekend rides.

Fairly impressed by the Ultimate’s results on my R15, i used it in my yamaha yZf-R3 as well and the results have been satisfacto­ry thus far. in the R3, the changes have not been as pronounced as they were in the smaller motorcycle but the performanc­e has remained consistent and i have not had any cause for complaint yet.

The castrol Power1 Ultimate is available in a number of grades, including 10w-40, 10w-50, 15w-50, and 20w-50. in both motorcycle­s, we have used 15w-50 and it costs Rs 744 per litre. Given the hassle-free ride i have enjoyed thus far, that does not seem like a steep asking price.
