Engine Oils

Re: Engine Oils

Thanks for the suggestions provided. One more query for everyone's understanding. The engine oil recommendation for HH Hunk is 10W30, what will happen if the below grades are used. Provide your inputs in terms of performance(throttle response), mileage, effect on engine(whether good or bad), etc. What will be the best grade to use through out the year in a city like Bangalore.

10W40
20W40
15W50

Only few grades mentioned as these are easily available on favorite brands like Motul, Shell, etc..

Any inputs from the experts? Also have anyone the tried using the recently launched TVS 10w30 fully synthetic engine oil priced below 600/-

In my Hunk, I have used -
10w30 - used while running in. I was never satisfied with this grade, city riding was fine but anything beyond 500 km, it sucks.
10W40 - used it with satisfaction with all round performance. Be it city traffic or long endurance run, it survived and served its purpose.
15W50 - on later half of my association with the Hunk, used motul 5100 15W50. It gives you smooth gearshift and little bit sluggish acceleration. Used 300V 15W50 too with not so good experience, since the the engine was shutting down often. Changed it within 500 km.

Later, I understood that I should not have used XXW50 oil because it surely flows slowly under certain operating temperature compared to XXW30 (manufacturer recommended) oil, may have caused damage to the engine. But, one of my friend used 15W50 Motul 5100 since long, without any complain.
But I have felt 10W40 was perfect for my Hunk.

I have never calculated the fuel economy as such, so can't tell you in this regard.

Re: Engine Oils

I've found shell ax7 10w40 to do well in cold and warm climates.

I recently filled my unicorn with shell ax7 10w40 though i get cold start i can rev it up smoothly in the sense earlier i was using veedol take off 4t plus then i could feel engine stress at 4k to 5k rpm now the same stress is felt at 6k rpm and there after

I guess for unicorn 10w30 is the recommended grade....regarding engine stress if u use anything greater than 30 the stress increases due to the increase in viscous friction...the same reason I used shellax10w40 twice consecutively and then shifted back to hero 10w30 and I felt engine is less stressed and definitely more revving...regarding touring even recommended grade for zmr is 10w30...so it s not simply the numbers ....its based on the engine characteristics...definitely 10w40 would be little good for touring but we are stressing the engine a little compared to w30.I have done intensive research on oils and practically applied and finally understood for hunk its 10w30 only.
.now using Mobil 10w30.
Though it is individual preference to compromise in few things and get something.

Ahha thanx mate the problem is i was looking in semi synth oil but very few options available here in locality in 10w30 grade so thought to choose shell ax7
Anyway thanx for great write up now ill try any 10w30 may be motul as its available widely

Thanks a lot for sharing your knowledge brother.

But, so far I can remember, in the owner's manual of Honda Unicorn, they have not mentioned the oil grade, they have only mentioned the use of different viscosity grade, depending on different ambient temperature - that I have seen myself long time back in Unicorn's owner's manual. As per my understanding, XXW40 will be always thicker than XXW30 in a particular operating temperature. Any additional stress on the engine may cause rise in engine temperature and the breakdown of the oil and followed by engine wear especially considering the ambient temperatures of our country. That happened with me once. But, certainly for increased throttle response and fuel economy nothing beats the 10W30 grade.
I also ride a ZMA, if I had been using 10W30, in my riding style, may I would have overhauled the engine several times. The Honda CRF 230F (international sibling of ZMA) recommends 10W40. The old ZMAs used to run on 20W40. So just only for crispy throttle response and fuel economy, I am not going to use 10W30 in any of my motorcycle and ruin the engine.
- just my thought.

s u are right. One should choose oil for their requirement not by simple grade number. I guess u are an intensive tourer. And 10w40 is also a good choice for touring. But u know initially hero used 10w40 as stock grade in karizma but then later they changed to 10w30....don't know the reason may be they thought w30 itself sufficient.

In old ZMA, the firing sequence was more advance resulting low fuel economy but aggressive throttle response and the outcome was poor fuel economy along with hotter engine. In ZMA -R, they have further detuned the system to provide good FE but less aggressive throttle response and relatively cool engine. In old ZMAs Ideamitsu 20W40 was used but in new engine they are recommending 10W30.
Not only for ZMA, they are recommending 10W30 for all their motorcycles. The reason may be increasing FE and crispy throttle response. Or, may be some other reason.

I strongly think, they are the manufacturer and they know their machine in and out. But, again how on earth they recommend 10W30 grade in our hot and humid climate? Even TVS is doing the same. Does not it is causing wear in engine while riding hard and with load under the hot summer?

Even the car manufacturers are recommending 5W30 oil for new engines.

Don't know the logic behind this. But I only know there would be a good one.

car is totally different. its core temperature is high and is expected to run at high revving range continuously. 10w30 will not cause any wear afaik, otherwise hero or TVS bikes will not run for 1L+ kms.. like i said, it is the way of balancing the parameters. 10w30 will increase temperature than 10w40, but what if the highest temperature is within the safe engine temperature. so they would have tested with low grade and found that the engine material can with stand the temperature caused by the low grade oil. in this way they are also achieving good performance (mileage, revving nature, less strain on engine).

we have dig much deeper on this to know the exact reason.

Re: Engine Oils

hi guys,

i have a pulsar180 ug4 clocked 22000kms...the bike is due for servicing...i have been using motul 5100 15w50 (ss) for the last 12k kms with a drain interval of 3k.

i was thinking of upgrading to motul 7100 20w50 (fs).

Should i upgrade or continue with the same oil. What would be the key changes i might notice if u upgrade.

Main reason to upgrade was to have a longer drain interval.

Plz put in your reviews and suggest the optimal oil for my bike

Keep using the same. I doubt you can extend any oil to more than 4K. It is best to change oil at 3K or before in most of the motorcycles. 15w40 Motul is SS and quite a nice oil.

Re: Engine Oils

which is better
motul 5100 or castrol power 1 20w50

Re: Engine Oils

I have a Honda trigger. few days back i change its engine oil with Shell advance ultra 10w40 full synthetic. The engine is smooth and a bit sluggish. but mileage is reduced from 58 to 52 kms. Previously the engine oil was 10w30 filled from service center. IS the higher grade engine oil is the reason of mileage drop?

[asn39]

Re: Engine Oils

it is probably because of the oil honds recommends 10w30 for fuel efficiency and pickup

besides if you fill up the oil at honda authorised centres take care that it is manufactured by IDEMITSU company there are other manufacturers such as TIDEWATEROIL , SAVITA CHEMICHALS, MAK LUBRICANTS

all produce oil and have same honda bottle but IDEMITSU is beleived to be best

i myself use shell ax7 10w40 i feel little sluggishness but at higher RPM bike is running smoothly
