great quality oil
great quality oil, perfect for small capacity motorbikes, can be used without a funnel for most motorbikes as the bottle has a pop-out narrow nozzle.

Suits my engine
Seen a few people comment that they did not know this is a semi-synthetic oil. If you change your oil frequently, as is necessary on small engined bikes with no oil filter, it is not worth spending more on a fully synthetic oil as you are going to drain it out long before it has broken down. I asked a Honda tech guy about oils and he said Power 1 is absolutely spot on for use in my little 125 Neo and if I continue to change the oil as frequently as I do at the moment - every 1,000 miles or so - the engine will just go on and on and on. The bike takes about a litre per fill so four fills for £35 quid is hardly going to break the bank. As anyone with one of these little 125cc restricted output learner bikes knows the only way to ride 'em is flat out!

No soy experto en mecánica, pero uso Castrol POWER1 4T 10W-30 en mi moto desde hace tiempo y puedo decir que va genial. Se nota que el motor va más suave, con mejor respuesta cuando aceleras, algo que se agradece en el día a día. El aceite protege bien el motor y la caja de cambios incluso en trayectos largos y con bastante calor, y la viscosidad 10W-30 funciona bien tanto en frío como en caliente. Además, es un producto que cumple con las normativas habituales y tiene muy buena relación calidad-precio. Si buscas un aceite que te dé tranquilidad y buen rendimiento sin complicaciones, este me ha funcionado muy bien.
