Castrol is arguably the biggest name in oil and I've been using their fully synthetic oils in my bikes for over 20 years. The bike always feels a little smoother and a little quieter after an oil change. It's a great price compared to other top brands, why use anything else? For those who have had the idea that fully synthetic oil makes clutches slip, be rest assured it's compete nonsense.

You will need a funnel. The container is a poo design and with most bikes having a near vertical filler cap this just pishes everywhere. Certainly for the Yamaha MT10 it seems to burn off more easily with my Motul 7000 never needing a top up in 12 months but this needing a bit here and there.

Castrol has in my time always been a good product, Castrol power 1 Racing works well in my motorcycles. I probably don't have to change it as often as I do,I change oil every 3000 miles,this oil is probably still good for another 3000 miles as it still feels and looks good.

Castrol Power racing is the only oil i will use and have done for 5 years or so. I run a Yamaha R1 1998 and have spent loads on the engine to get it to where i want it.. I regularly participate in track days at Brands Hatch & Silverstone so i obviously want the best protection i can get, and this is the best! I would highly recommend it!!

Have used this in my can-am Ryker rally for the last four Servises and he loves the stuff his little heart hasn’t missed a beat, would definitely recommend.
