Castro Power 1 4T
27 Aug 2025 by Anonymous
Always used Castrol oils in my cars and bikes; I guess it’s down to personal experiences and preference ultimately. The Power 1 4T semi-synthetic boasts good performance. With regular oil and filter changes, I couldn’t say that it’s any better or worse than other premium brands. I always use with a K&N oil filter. Stands out as being red in colour, if that helps! Will definitely continue to purchase and use this oil.

Genuinely excellent product

Maybe it's the placebo effect? Who knows. I always feel better knowing my bike has the proper products in it. It is pricey but for peace of mind it's totally worth it.

Best in 40yrs
03 Jan 2025 by Joe B
Castrol Power1 is the best oil for my bikes. Tried different oils over the last 40yrs and this seems to be the best for gear changes, clutches ect.
Quiet engines smooth gearboxes.
Even transformed the gear change on my new T7 from rough to silk smooth ?

Best buy oil!

Always use Castrol oil. Bought four litres of 10-40 at the best price, I could see. Much cheaper than I could get it locally. Arrived the next day. Great services all round. 23 year old VFR, runs like a Swiss watch!

Oily oil
17 Sep 2023 by Neil D
Wow! That oil was oily, it seriously didn't disappoint! I don't think the inside of my Triumph Bonneville has ever been as oily as this oil has made it! Oh, and it was reasonably priced with quick delivery too! If you want really oily oil at a reasonable price, this is the oil for you!
