Shell Advance Ultra 4T 10W-40 API SN Fully Synthetic Motorbike Engine Oil (1 L)

Very good performance must buy around 600rs u can clearly see the difference after using in bike very good quality

Good one for Activa BS 4 engines.

Bike: Suzuki Gixxer SF 155 BSVI (2021) Weather: Summer (Hyderabad) ODO: 15000 (1st 2 services with ECStar, later 2 are with Castrol Power 1 Ultimate Fully Synthetic) This one my 5th service outside Suzuki and you won't believe how smooth this engine has become. Got this for 609 rupees or something and it totally worth the price paid. Bike has become totally smooth since the first 2kms while Castrol was feeling a lil rough since day 1 is the reason why I switched to shell advance. The engine revs smoothly, Gear shifts are now on point and no need to put too much pressure like before (Gixxer owners can relate) I'll update the mileage and smoothness after riding 500-1000 kms on this engine oil. Update (1650kms): Initial engine feels smooth without hard revs Engine acts super smooth till 55kmph, later it starts stressing out. 75-80kmph is somewhat a good powerband and highway crusing speed. It obviously gets heat up in traffic bcz of air cooling as an only option but way less than the Castrol Power 1 Ultimate (fully synthetic). Now my legs don't get fried in the traffic. Gear shifts are fine in the beginning and after the engine heats up in traffic it becomes rough. Miliage is still pretty similar to what I was getting previously around 47kmpl max Since I've changed engine oil I thin the top speed has reduced to somewhere around 5kmph. But I'm not confident of it's the oil or the last service. Soon I'll get it checked. Update (5000kms): Yes I did stretched it upto 5000kms just to check the oil's life and it surprised me on every added kms. It still runs smooth and engine revs smooth as well. Initial rides are super quite until I get stuck in a traffic. Best part is the cam & tappets don't make noise anymore like they did on Castrol after heavy traffic escape. The engine oil is super reliable till 5000. Did 150kms stretch without break on highway while the oil already ran 4500 kms and trust me I see no changes. It's that good. Bought it for 609 and now it's 700. But I suggest you to wait till it comes down to 600. Buy in bulk so that you won't need to wait for next service. This oil is 10/10 Update (ODO 28000Kms) This is my 3rd time using Shell Advance Oil and since I'm seeing the price is well over 700 these days I've purchased Motul 7100 for 750 rupees. I want to give Motul a shot and see if it shows any difference for better! Overall 13000Kms with this oil and I change oil in every 4500-5000kms with it and I won't recommend to use it above 5000kms as it starts showing it's age afterwards and it's a safe stage for the next service. The oil did perform pretty well. Engine is still healthy and in controlled temperatures. It's just the traffic that kills all the fun. I'll update the performance of Motul 7100 after 30k service. Till then watch the price of it and get it whenever it drops under 650rupees or so. Just don't buy Castrol.

This one of the best oil I have used from the mid Summer and done every high temperature ride and valley ride with full rpm limit this oil performed so much best in mt15. And give me milage around 57kmpl in highway ride at speed of 70 to 80. This oil performed much better than motul 7100 I am not saying that motul 7100 is not good oil. this oil also performed temperature ride very well in summer also. But the cold start and gear shifting get smooth in shell advance 4t ultra. And motul 7100 is best for higher rpm riding it performed well great and motul 7100 10w 40 gives milage of 53 kmpl in highway and shell give 57 kmpl in highway ride city ride is depends upon your riding style. And use shell in winter and rainy and use motul 7100 in hot summer.
