    Rated 5 out of 5 by from A1 product Castrol is a legend in the motorcycle world with a pedigree second to none, this 10w 40 is ideal for multi-cylinder bikes and a good "jack of all trades" in general. I have used it for 20 years, it costs a bit more than other oils but you get what you pay for with this. The only problem I have with this product is its info, nowhere on the packaging does it tell you if its a mineral...semi...or full synthetic, the oil code from your bike manufacturer does not tell you either cos the oil code just tells you whether it is the correct grade of oil, not its base blend. I have emailed Castrol about this and they said" we have had hundreds of complaints about it but there are no plans to change the labeling". Great oil never the less. Get it !

    Rated 5 out of 5 by from This is the Oil that the manufacturer recommends for my bike. I own a BMW 650 Sertao motorcycle, that required a service. This is the oil that BMW recommend for my bike, so that'll be why I chose it. I looked on line and could have bought it a few pounds cheaper, but I didn't want to wait for it to be delivered.

    Rated 5 out of 5 by from Castrol Power 1 4T 10W/40 Motorcycle Engine Oil - 4ltr Used this oil previously and found it noticeably better quality than alternatives. So was naturally pleased that Halfords had it at a decent price when I was shopping for this specific oil.
