I'm new in this forum. Sorry if this question has been asked before, I've searched the forum but didn't get any satisfactory answer.
I've some questions regarding my CBR 150R Engine Oil.
Honda recommends it's own 10w30 Mineral engine Oil.
Last time i switched to Castrol Power1 10w30 semi-synthetic. The experience was smooth and powerful. But only 900ml bottles are available here, besides I want to switch to Motul.
I checked the Motul website and decided Motul Technosynth 5100 10w30 will suit best.
But when I tried to buy it, I even contacted 3-4 authorized Motul dealers in Kolkata. But none of them got 10w30. Said people don't use that and suggested to use full synthetic 10w40 instead. According to them viscosity doesn't really matter. Some even suggested 15w50 .
I'm rather confused. Since 10w30 is not available in Kolkata, can I buy it online?
Or should I switch to different viscosity like they suggested
Any help would be much appreciated.
Thank a lot.
P.S: My bike ran around 6000km.
