Different packaging, but the same great product

I searched for the most suitable engine lube for my bike, combining performance and price. This was a bit cheaper that normal I thought that it was old stock as the packaging looked like the old design from years ago.
Anyway it's the new more sustainable, greener, easier to use bottle. Still containing the same high performance lube. What's not to like !

Purchased this oil for my bike. As it’s the best option for my bandit 12. The price of oil is now stupidly expensive. Yet sports bike shop selling it almost half price. I thank you very much!

I have been using Motul 7100 oil in my triumph for the last 10 years but the prices are on it now are somewhat ridiculous. I did some research and the reviews on this Castrol oil were quite good. The absolute deal breaker for me though was the ridiculously low price that Sportsbike shop were selling this for. I did my oil change this week and took the bike for its first ride yesterday to get it's MOT done. What I can tell you is that the gear changes on the bike all felt incredibly smooth both up and down the box. Obviously I am not an engineer and be able to tell you about engine wear and everything like that, but Castrol have been in the business for years. You know that you are buying a quality product and that your bike will be protected. I will definitely buy this again.
