    Rated 5 out of 5 by from I only use castrol At the last oil change I felt an immediate difference when changing gears and it was only at 5000 miles (recommended 6000). Used it before and it's a definite improvement over Yamalube

    Rated 5 out of 5 by from Product good - service poor Ordered online to click and collect. Went to collect, waited 10mins for service, given the wrong oil! Luckily spotted that. Oil tagged withy name, which was on the shelf, was then found and handed over. I paid and left. 1 sec before pouring the oil into my bike I noticed this was the wrong oil also. Annoyed. Went back to shop and made, sure they gave the correct oil! Blimey. This is critical stuff for engines, more care should be taken by them and less trust used by me. Be careful out there...

    Rated 5 out of 5 by from You get what you pay for This oil is expensive. However, it is approved for BMW air cooled boxer twins, so if you need to top up and keep your warranty intact, it's worth it.

    Rated 2 out of 5 by from Fully Synthetic Oil. Great oil but where its fully synthetic it burns a lot faster than the part synthetic oil, so you more likely to have to 'top it up' between oil changes. Over all its nothing amazing so why bother. unless you manual says so, I'd stick to semi synthetic oil.
