With so many brands in the market and faced with the choice of synthetic, part synthetic or non-synthetic, I thought it best to stick to the brand that I consider to be the best.
Only the best will do

With so many options to choose from it's best to select the most well known brand. The Castrol brand has been associated with automotive oil developments for very many years. It is renowned in this field so you know that it will perform to the highest standards.

Bought Saturday night and SBS managed to despatch so quickly I got it Monday. Totally unexpected but gratefully received. It's Castrol and meets all the requirements stipulated by Honda for my bike.
Not recommend
07 August 2023 by Stan N
I can't call this oil "quality product". For two weeks looks like year use on the engine. For new Honda bikes I would NOT recommend this oil.
Never happened before with Putoline oil. Same store-sportsbikeshop!
Obviously the problem is oil. My service go get change it and no problem with new ones.

Hard to find elsewhere but Sportsbikeshop came up trumps and delivered superfast.

After adding oil noticed a quietening of engine running noise even though previous oil wasn't that old.
Fantastic delivery speed
