Castrol POWER1 ULTIMATE 10W-50 4T Synthetic Engine Oil for Super Bike | With 5-in-1 Full Synthetic Technology | Meant for High Performance Bikes | BS6 Ready |1L

This is one of the best 10w50 engine oil available in India at the moment. Made in India and for India especially due to our climate condition and riding style.The packaging has changed since Castrol has updated it's logo in 2024.I have been using this engine oil in my Jawa 42, Yezdi Roadster and my friends Pulsar RS200 and NS200 and recently purchased Triumph Speed 400.I have purchased 2 ltrs of the oil this time for my Meteor 350. Though RE says 15w50 and semi-synthetic, I have changed it for performance reasons, mileage, heating issues. This oil is being used since 2 years on my bike and i feel the price fully justifies the value of the product.After an extensive research i found out that this Engine Oil is made from a mix of Group 3 - Group 4 oils and is fully synthetic in nature.During one of my long rides, I could say that the oil performed really well and the bike has not given me any sorts of engine related problems till date.Even though the oil didn't lose its properties, I change this oil at 8k kms as Castrol says 12k limit but i change it beforehand.I used to blindly believe in Motul oils before due to their Ester branding tech on the bottle but during these years I have found motul to have evaporation loss in 2-3 months of usage and have found that they are mostly not suitable for Indian climates.Well to each his own, I am using this product since the launch times and found it to be very good backed by the Scientific side as well as practical aspect.For those who want the numbers, here it is belowDensity - 0.8535Viscosity@40 - 116Viscosity@100 - 17.25Viscosity Index - 165Pour Point - -36cFlash Point - 208cTBN - 7.8

This oil provides exceptional engine protection, even in extreme temperatures. My bike's performance has improved significantly, with smoother acceleration and reduced engine noise. The formula ensures excellent lubrication, reducing wear and tear on engine components.

It is really good engine oil. Acceleration is top off the level. It helps to keep engine smooth and improved mileage. No over heating and vibrating range is very low. Perform better at high speed.

Excelence productGood delivery

This synthetic engine oil ensures smooth performance, reduces engine wear, and enhances durability. It provides excellent heat resistance and keeps the engine clean for optimal efficiency. Ideal for high-performance bikes.

I've been using this engine oil for a while now, and the difference is noticeable. The engine runs smoother, quieter, and feels more responsive, especially on long drives. I’ve also seen a slight improvement in fuel efficiency. What I like most is that it keeps the engine clean, reducing sludge buildup.

Very nice

Pros:1) Price is 100/- cheaper than other 10w50 fully synthetic oils.2) Light oil: less warm up time, good for city, accelerates faster, less hesitation just after cold start.3) Moderate heating management, Shell shines here.4) Moderate Gear shifting, Motul shines here.5) Pulls faster in high revs due to rev-happiness properties in the oil, but not the best like Motul 300v.6) Mileage is excellent due to light oil.Cons:1) Lasts about 2000km, then engine becomes less smooth.2) Not smoothest like Shell or Motul.3) Engine sounds harsh after engine is heated up in highway run.4) Mechanical sounds are more than other Shell or Motul.5) Gear shifting is not smooth after the engine becomes very hot.6) Color goes full dark just after 1500-1600km, not like Shell or Motul.
