Engine Oils

[avisonly]

I have a R15 V 1.0. The bike has ran somewhere close to 8.5k mark is 3 years. lately, my bike has become rough ans the engine oil is on the verge of being changed. I wish to change to fully synthetic engine oil. Rob, (an xbhpian) suggested me to go for semi synthetic oil first, and then go for fully synthetic in the next change. Previously the bike was serviced at a Yamaha SVC. I have no clue which oil they put in the bike.

Can some gurus let me know which is the best engine oil for my bike. I just want my bike running smooth.

One more problem is my bikes headlamps at night are insufficient. Any bulb change can help me?

use motul 300V FS for good smoothness. and frequently clean your chain & lube with SAE 90 oil then use chain spray.this way your bike is much more smoother.I think yamaha recommended grade is 15w50 go with same viscosity.

Motul 300v here 5W-40 and was using Castrol Power 1 racing before... I sorta like motul more...

Down south here in Hyderabad My Splendor overheats like hell and engine becomes very-very harsh and make grrr sound the bike when the bike is picking up speed from standstill that too after riding just 10-15 kms.

I was so fed up with the engine overheating that I mounted a 120mm computer Aux fan just above the engine to cool it .
But I had to remove it because the battery was getting drained,my Dad told me that I am taking too much care of it and anyone who saw the fan was laughing .
I am planning to put it again because my bike is on Full DC now,so no draining issues.

Anyways,I have used many oils from 10w30, to 15w40 and 20w40.
I have used Hero Honda 4t,Servo,Mak 4T,Castrol 4t xtra and power 1.
But no oil could reduce engine's harshness considerably.

Currently the bike is running on ELF moto Gold 20W40.
Yet to try motul and gulf pride and other 20W50 oils.
Pinaki ji,If you find a solution please let me know first.

All of last summer Motul 3000 4T plus 20w40 solved it for me totally . It's also running superbly in my cbz-x . Try it .
I got it for 200 Rs then , now it's gone pricey @ 250-270 Rs per lit(depending upon the surprise discount coupon inside) so I am on the lookout for a cheaper but good 20w40 again . Next I shall try the gulf pride 20w40 failing which will default to that motul again , damn the cost .

Hi
Please advise for a good Engine oil for my Pulsar 150 UG4.
Manual recommends 20W40.
Was using Castrol Power1 but got varied performance everytime. Now I'm vary of Castrol as there r too many fakes available.

hi, why do you think that chaning to higher viscosity oil will cure your problem?
I am an ex-owner of splendour and know what you are talking about.
The first thing to check is the carb setting. Is your bike consuming lot of petrol?
Second thing is the clutch. If you havent changed clutch plates recently try getting fresh original plates. Old-dead plates make the acceleration rough and bike starts consuming more fuel, also get a complete service done especially air filter cleaning and carburetter cleaning . As you are focussing on oil and not looking into the real reason for overheating, this issue will never get resolved. High performance bike do get overheated coz of high fuel consumption but a splendour getting overheated is rare, no matter how hard you ride it. Outside temperature (in hyderabad) is not so harsh all the time and the frequency of you trying all these oils make me believe that the issue was even in winters which finished last month and were quite cold here in hyd.
Air filter, carb, clutch!! Do let us know your fuel efficiency.. I doubt it is anywhere near 50!
Take care.

Abhinav'jee, castrol power 1 doesn't not match recommended grade for your bike since it is not 20w40 . Try Motul/Gulf/Elf/Yamalube etc, plenty of good 20w40 motorcycle oils around .

shell advance ultra - 10w40 750 rs. Lasts 5000 km/ six months.

Hi pinakiji,
castrol power 1 is 15w40 (i know you know it) and fits perfectly in a 20w40 recommendation.

Yes Muztariq'jee, I have heard some rumors of it being 10w40 or 15w40 . But 10w or 15w oil is not the same as 20w , and certainly not in summer in the Indian plains , when 20w is recommended by the engine's maker .

[muztariq]

hi again,
i dont know why you think that in summer you require 20w and in winters you require 10w.
I am in for a healthy debate.. Please dont mind.. Lets conclude something here. :-)
in winters of kashmir you may require a 10w grade as the temperature falls below 0 C, but anywhere around in india where temperature doesnt go below 0, a 10w or a 20w grade oil is equal. But if you use 10w in place of 20w its always beneficial as this oil flows faster than 20w when you bike is lyinh cold in the morning. Hence 10w is always better than 15w which is even better than 20w.

that Aux fan is of no use ...since engine is not enclosed...the natural air flow is much more powerful to remove heat.what is the present oddo reading and is the mileage normal? i hope the exhaust valve is not leaking....but main suspect is the clutch plate.

In summer the temperature can go past 40 degrees so the heat generated will be high enough to effect the lubricating film between two rubbing surfaces. the main point is that viscosity of oil decreases as the temperature goes higher and 10W30 being thinner oil then 20W40 will struggle to maintain lubricating film at higher temp.

i am here to clear all the myths you and others have buddy.

Conventional oil's viscosity decreases with increase in temeprature but the oils which we use in our bikes.. The viscosity increases with temoerature.
In the morning when your bike is lying cold, the viscosity is low, when you start your bike the viscosity starts building.. And will go upto the w30 or w40 or w50 as the latter rating of the oil suggest.

It a big misconception that guys here use lower viscosity oil in winters and higher viscosity oil in summer.. Its not at all required. The manufacturer gives viscosity recommendation as per the clearances the engine was built with. If he recommends 10w30 you should use 5w30 or 10w30. But you cant use 20w40 in a 10w30 recommendation in summers. You are killing your engine by using higher viscosity oil.
More to come.. Wait i will edit this post..
