Castrol Power1 4T 10W-40 Full Synthetic Motorcycle Oil, 1 Quart, Pack of 6

Kind of expensive but much cheaper than buying from the dealer. It’s sometimes hard to find in stores. Very high quality product plus full synthetic is the way to go.

If you're looking for a motorcycle oil that can handle the heat of summer rides like a champ, this one is a total game-changer! My mechanic raved about how well it dissipates heat, mentioning that you can let your bike idle in scorching summer weather for over an hour without the fan kicking in. I used to swear by diesel oils for my motorcycles until I found out about the potential drawbacks of using them in gasoline engines. Switching to this oil was a total game-changer for me! While some may believe it's a full-on synthetic, the truth is that it's not; it's actually a highly refined crude oil product. So, if you're after a true synthetic base oil, you'll need to opt for a 100% Synthetic one.I can't stress enough how much I love this oil for its heat dissipation properties and its overall performance. Trust me, if you want your bike to run smoothly and coolly during those hot summer days, this is the way to go. I highly recommend it to all motorcycle enthusiasts out there!

Purchased this Castrol motorcycle oil after having a hard time finding reasonable fully synthetic motorcycle oil locally at a reasonable price. There's not a lot you can say about oil, but my Kawasaki really prefers a good fully synthetic which seems to improve the 1-2 gear shift, and this oil works beautifully. The six quarts includedi in this box will take care of two oil changes making this a good value at the price.

One of the best oils for motorcycles, if you find a good deal on a case, jump on it!

Great product. Atv runs great.

How much can you really say about oil? I want a synthetic oil for my 06 VFR and this is the best price I could find for a reputable oil. I change my oil annually since I only get to put less then 3-4000 miles a year on my bike. This oil seems to look fine even after a year. Bike shifts and runs smooth so no issues there. I will continue to use this oil unless the price jumps way up. If this review was helpful please click yes below!

I purchased this because of the "marketing" material that came with my Triumph Tiger. It says to use Castrol full synthetic. Why not. This isn't the cheapest, and it's not the most expensive. The oil change was standard; it's oil. What I did notice afterwards was a strange smell I'd never smelled after an oil change. Really weird. Perhaps something different in this oil that smells when small drips burn off while riding. I don't know. Shifting is OK, but not as smooth as with the previous full synthetic brand. Overall it works. But I'll use another brand at my next change.

I received the delivery promptly, and I must say that this motorcycle motor oil has been a game-changer for me. After using it for years, I firmly believe it is the best option out there. The way it keeps the engine running smoothly and quietly is truly remarkable. If you're looking for a product that ensures your motorcycle operates seamlessly, this is definitely the one to go for! Highly recommend it for anyone who wants their motorcycle to perform at its best.
