Castrol POWER1 ULTIMATE 15W-50 4T Synthetic Engine Oil for Super Bikes | With 5-in-1 Full Synthetic Technology | Meant for High Performance Bikes | BS6 Ready |1.2 L

2014 Duke 390I was a little skeptical of this oil as Castrol brand is famous for its duplicate products in the market and after using 300 V2 I didn't liked any oil for my fire breathing 390, then I rode a 390 with power1 ultimate in it and I can feel the difference between the two (7100), at redline the engine noise was noticeably quieter and smoother. So I decided to give it a try, was still skeptical of not getting an original product till the day I recieved it. And it was genuine, I checked the QR code etc on it. Thankyou Amazon, hope that you will never disappoint me ever.1. The oil is thinner as compared to motul 7100, so it runs faster throughout the engine in cold starts which is awesome.2. I found the engine to be more responsive on the throttle, pulls smooth n cleanly and engine noise is also reduced noticeably.3. Didn't notice any engine temperature fluctuation b/w the two, as old gen 390s are fire breathing monsters.4. In motul the gear changes on new oil are notchy as oil take 400-500 kms to get into a sweet spot, not in this case.5. I have to examine the evaporation of the oil as these ktms tends to blow by6. Also to examine the mileage of the oil, motul gives up @4000 kms.

I have been using this oil for almost over 2000 kms. It takes 100 kms to settle the bike with the new oil as I was using Motul 7100 before. But after 100 kms the engine become smooth, less vibration, gear shifting is smoother than Motul 7100. Only one con is bike heats up a little more with this oil than Motul 7100 and radiator fan stays up for a little longer. Rest all is good at this price point. I will surely recommend this oil for KTM Duke 390

Amazing product. The 5in1 full synthetic formula in Castrol POWER1 ULTIMATE works wonders. Recently used 15W50 in my BMW GS 310 where BMW service was using 5W40 which is not suitable for this engine and Indian climate. First impression is amazing good throttle response, no over heating issues in traffic which was the case with previous BMW oil. All performance bikers should try this once and feel the difference between MOTUL, Liqui Moly and Castrol POWER1 ULTIMATE

I have been using this oil for 2000km now. I have an RR310 and heard that the tvs service center oil is semi synthetic and could do much better in performance so I purchased this. After a lot of research of whether to go for 300v or 300v2 I thought of saving some money and going for this. I also did the full Motul treatment of oil flush then new Engine oil additive. Had read the comments that some people noticed higher oil temperature. I let it slide that time l. I am kind of regretting this purchase because of how hot the bike gets. It easily gets 100-105 in stop and go traffic and in complete stop it gets more than 110c can go 112degrees as well. I have to turn off my bike every chance I get in traffic signal stops.

Some time my bike very smoothly but in trafic I thought why I purchased it but over all I m satisfied except trafic it's good, Today is 17 Feb 2023 after using 3 month 15 day still my bike is working very smoothly I m riding approximately 10000 km and I m completely satisfied I gave 10 out of 10 .I m using thunderbird 2010 model from past 12&half year I m using motuel oil and changed oil after 2500km and my maintenance charge is approximately rs 2000 rs per month now in past three and half month I paid ₹2200 so I recommend u guys for bullet 350c.c castrol 15w15 is aussam in traffic they behave differently but after 15 to 30 min it behave differently its aussam .

Too bad you can't find this anywhere locally even on Tier-2 cities.After using it for 4000 km, I was still left with 850ml old oil. This is the best stuff you can buy in India in my opinion.Make sure the higher number (W50) matches the recommendation by your vehicle manufacturer's engine oil rating.For example, you can use this oil for engines that require 5w50, 10w50, 15w50, 20w50.

Used the 10w40 oil in my R15v2 and it was so much better then Motul or Yamalube. Undoubtedly the best for R15.Impressed with the performance in R15, used 15w50 in my RC390 bs4, and the performance is good, the bike runs quite Smooth But Heats Up alot more then it does with Motul. It’s smooth for the Engine but not good with Heat Management in RC390 bs4.Hope you find this Helpful.
