All honda engines recommends 10w 30 grade, throttle is also 10w 30.

Yes, even the service person recommend 10w 30., So what's the major difference on 10w 30 /10w 40... It is for getting suitable with climate or what?

Every engine is designed with a specific grade of oil keeping in mind. If you put a thicker oil , oil cant pass through small oil passages in engine which will cause inadequate lubrication and hence will cause wear and tear of engines. Using a thicker grade oil also exerts pressure on the engine oil gaskets resulting in oil leakage, so it's always advisable to use 10w 30 oil . We've many options such as motul 5100 semi synthetic, honda throttle, tvs 10w 30 synthetic oil and also liqui molly 10w 30 synthetic oil which are more than enough for honda engines.
In 10w 30 or 40 , 30 and 40 implies the thickness of oil at 100 degrees. If thickness is more then there will be low lubricity in internal bearings. And many causes of engine failure occurs due to use of wrong grade oil. Honda engineers know more than us isn't it , otherwise why will they recommend grade which is harmful to engine. If ambient temperature is more use 10w 30 grade synthetic oils which have high heating resistance capacity than conventional oils.

Did you know that when Honda introduced the unicorn 150/shine here, they recommended 20w40?

Earlier Hero Honda recommended 20w40 for their bikes. Similarly Yamaha used 15w50/20w40 for their FZ/R15.

Now the manufacturers have shifted to 10w30/10w40 for lesser emissions/higher fuel efficiency. As far as I have seen, Yamaha and Suzuki manuals provide a graph of temperature vs oil grade-

In my unicorn 160/activa manual, 10w30 is recommended for all temperatures. This grade is not at all suitable when the temperatures are always above 30-35°C.

Which grade of oil you used in unicorn in summer

I have 2008 Honda Shine, yes earlier they recommended using 20W40, bit later 10W30. This might be due to some internal changes in the subsequent revisions.

Now, service centre people will tell you it's due to starting problems and what not. But, if it was so, then they'd be recommending to use 10W40 oils.

I'd say you can drop the lower value by 10 in winter and increase upper value by 10 in summer. It'd not cause any problems, infact it'd help with the environmental conditions.

Will you recommend 5w 30 motul for hornet

I'd say for winters, you can go for decreased number of first digits before W. So yes you can use 5W30 if the recommendation is 10W30.

Just note that, if you use synthetic oil, it's base oil should be PAO not Ester. PAO has the widest compatibility with the most materials while Ester has been known to cause seal deterioration and then leakage.

Although, if OEM recommends oil with base oil Synthetic Ester, then they might have used seals which are compatible with Ester oil.

I know this coz I'm employed in an industrial lubricants company.

What's mentioned in Hornet manual about engine oil?

I think 20w40 should be good enough consider that the temperature there is below 30-35 on normal summer days. I've always used 20w50 on 150cc+ bikes and 20w40 in 100 to 125cc bikes. Has always worked out for me. No issues with either of the grades on my old Honda Twister, Splendor Pro, Unicorn and my friend's Hornet as well. I think [MENTION=37035]ashwinprakas[/MENTION] uses 20w50 as well.

I stand corrected. Like Shasank said above, 20w40 was the ideal grade and I think since the day 1, the SVC people here themselves suggested that I go with 20w50 as soon as I was out of warranty. My trusted mech said that Pulsar and CBZ Xtreme used 20w50 as well. I cannot say about other places but 20w50 seems the ideal grade to use above 150cc bikes due to the temperature conditions here.

I've used motul 5100 10w 30 semi synthetic with easter , should i drain it so that my oil seals are safe.

Re: Honda CB Hornet 160R Owners Experiences

You'd have to refer to other's experience with that. But semisynthetic wouldn't be that harmful. Also, 5100 is a trusted oil which many people on this forum have used and haven't faced such issues. So you're good to go.

For your knowledge, PAO has wide compatibility while Ester has better thermal stability, so it helps in conditions like bike engines which are power dense.

Re: Honda CB Hornet 160R Owners Experiences

Rather than recommend oils I guess the best think to do would be the direct people to resource and then let them arrive at their own conclusions because oils are one among the subjective topics of motorcycling and to each his own.
[MENTION=95957]Bismaya[/MENTION], Yeah, 20W50 for everything I ride or drive.

Yeah practical testing is the best way to see what suits your ride.

Thanks , for the info suggest me a pao based oil so that i can use it without worrying.
