Yamaha is focusing on Yamalube sale which is a pathetic oil as compare to SHELL. I am planning to try SHELL AX 5 20w-40 as my next oil change and it must be much better than AX 3.

AX 3 makes the engine less noisy and it feels like you're running a thick oil. Also, its grade is SJ which can be more suitable in summer. I will try AX 5 and then share my experience with it.

I read so many posts against yamalube now i am confused between company’s recommendations and people experiences.
If some one help in this matter so i can stick with one oil grade and brand.

Try SHELL AX 3 20w-50 red bottle and you surely will love it.

I have tried liquimoli 20w 50 which is 110% not suitable for ybz and over prized too.
For yamaha lube this oil is better only for 6 to 700 k.m it may not hurt the engine for more use but it not feel good to use more then 700 k.m in garmi dnt know how it will perform in sardi.
Third is shell AX 3 20w 50 currently have driven 300 k.m and performance is great no cluth slipping less sound after engine heatedup. Top speed achieved twice with ease. Easily available low price and there r many well known fuel station where u can buy orignal. So m using shell.
And I ll keep using this oil in sardi too until or unless 20w 50 grade give me any issue in low temp.

I am facing clutch slipping issue in Yamalube while there was nothing such error when I used SHELL engine oil.

[pwuser149716645359]

Injust changed oil pic is attached. Is it right oil coz shell station were insisting me to go for 10 40 but i ised 20 50

Aap ne kbhi Zic try kiya hai ? .........
i m using Zic M7 10w40.............
The result is amazing.....................
online orderd kar k mangwao home dilivery hai aur orignal mily ga
pehly gd110 , phir gs 150 , aur ab YbZ , 3 saal se istamal ker raha hon
koi issue nai hai,
1000 km bohat aasani se complete karta hai aur clutch sliping ka koi issue nai hai,
is dafa socha 1200 per change kar k cheak kiya jae, 1100km bike chal chuki hai,
Engine Oil is Still Best Condition, Agar 1200km tak performance Achi rahi to 1300km Tak chala k cheak karon ga, kyon k aaj tak mai ne 1000km se zyada nai chalaya,

10w 40 grade is not recommended by yamaha.

[awaiz43]

G yehi oil hy. Or subah bike thora time start chore conz yeh thick grade oil hyn kuch time lgta hy working temp pe aane pe.

[naseer_jaan]

phir aap different oils k sath tajurbaat jari rakhain

[boldpisces]

Bro using 10w in a bike which is having recommendation of 20w by company is must be insane. I just hate ZIC oil and Kixx too. They both are over priced and poor in quality. Anyway, my last resort is only SHELL or I might try to find Valvoline.

[pwuser149716645359]

Thanks till now clutch slip issues looks resolved to me.
I drove around 50 km and sound of bike was normal.

[pwuser149716645359]

Thanks for help.
I also said to shell guys company recommend 20 50 grade thats why im using. I am hoping i will stick to this oil insha Allah

[boldpisces]

Yes SHELL is far better than pathetic Yamalube, ZIC, Total, Liqui Moly & Meguin. Trust me, I have tried all these engine oil in my bike. Next time, try to find same grade in yellow bottle means AX 5 by SHELL. Don't ever use 10w oil in your bike as it will make your engine weaker soon. Also, it will make your engine noisy and you may face over heat issue too. You can use 20w-50 and 20w-40 respectively for summer and winter.

Bhai correct your facts a bit.
10W OR 20W means the thickness of oil when cold and the other number say 40 OR 50 means thickness of oil when hot.
A oil which has 10W that oil will flow faster through the engine when cold instead of a oil that has 20W that will flow slower causing more wear.
The second number is what a oil will behave like when it's hot 40 weight oil will be thinner when hot and 50 will be thicker when hot.

[boldpisces]

Thanks for the correction but I didn't want to explain this much as I guess that everyone knows this fact. Further, 20w-40 is also quite thin oil as compare to 20w-50 as I checked both oil last time by SHELL and 20w-40 was falling down more quickly than 20w-50. Using 10w would be a cruel and silly attempt on YB 125z engine. However, someone can use it for 20 to 30k and after that engine starts producing smoke and he ultimately requires engine overhaul.

You are not getting the point.
You are just jumping to solutions way too quickly.
A oil having 10W and 20W respectively will have no effect on how a oil behaves when hot it will effect only when oil is cold say if at 10 degree centigrade 10W oil will be thinner and 20W oil at same temperature will be thicker.
The other number is what a oil will behave like say when it is at 100 degree centigrade a 40 grade oil will be thinner at 100 degrees than that of a 50 grade oil at same temperature.
Even if a oil is 10W-50 that will be thinner than 20W-40 and 20W-50 when cold and a 10W-50 will have same thickness when hot like 20W-50 oil. 20W-40 will be thinner than 10W-50 when hot.
I Just wanted to get your facts correct about engine oil's didn't wanted to start a war on this topic.
You guy's should use 20W-50 as yamaha suggests to do so. But don't deny the facts.
