Re: Engine Oils

It says "20w-40" or "20w-50"

But we really don't require 20w50 on 150cc bikes, you can use xxw30 or xxw40 above that would just degrade ur performance

I once used 20w 50 on my Pulsar 150 and could feel the bike 'suffocating' but it was very smooth. I then changed to 20w 40 and it was breathing easily again.
Never ask for suggestions from the shop-keeper. Most of them would say, "Saar high speed engines need 20w 50 " which is not right always unless recommended by manufacturer/owner's manual.

Re: Engine Oils

FZ has both 20w40 and 20w50 recommendation as per owners manual. And only 20w50 as per service manual.

Regarding your query on FZ thread, I dont think you should lose sleep on the issue. 5100 is a good oil and R15 oil that you have been using may be slightly less thick but more or less same performer as Motul 5100. With time the ride quality would improve.

Are you sure 20W50 is recommended for FZ? My manual only shows 20W40 recommendation. Also, the Yamalube for FZ is 20W40. I have not seen 20W50 oil at the SVC. The 15W50 oil is for R15. The 15W50 oil of Yamalube was crap. I will wait and watch the 5100 oil's performance for some more kms.

Cheerz!!

Most people get this theory wrong of always thinking that bigger *fixed grade* i.e. 20w50 15w450 instead of 10w40 or 15w40 will always result in smoother performance on all weather conditions. Apart from the weight and viscosity ratings there is a little more into this notion.

Muzz, if you guys go back perfectly summed up the relation between grades, viscosity and their uses, that's one. But I've known gearboxes of cars which have trouble using a higher grade than the recommended level say the difference is like just as 10% increase (i.e. w10) and that makes the gearbox shift and feel sluggish, revert back and it was all normal. Same goes for wet clutch engines where they do have certain tolerance range. Using a 20w50 in a Splendor will really make it sluggish at low ends and unless and until the oil is heated and it's really gotten into rhythm you can't expect a good performance. But yes, I've used the same too, where the bike is sluggish, but the vibrations are arrested but way sluggish performance at low end speeds coupled with my climate, and the time it takes to get heated up.

Upon using a lesser grade, I can feel the difference almost entirely on the engine startup, it feels smooth, idles good, irrespective of the temperature wherewas it's not the case with higher VG oils.

The point is simple and as petrolhead rightly pointed, never go by the shopkeepers, just do some basic research and you're done for the most part. Opinions only add to the woes.

Thank you mate! The same is the case with so called authorized service centers. They use 20w50 for all vehicles unless the owner requests or rather insists to use 20w40. I guess they have barrels of 20w50 oil and the mission is to empty the barrel soon .

Thats what i said in my first message, I noticed clear difference in Performance after using W-40 graded oil.

Yes bro. Thats what i quoted in my First message, That W-40 worked better than W-50 in my Fz.

If you're replacing the oil by yourself, apart from all the procedures, fill the new can with the used oil from the tray and either give it to your local mech or a mechanic you know or any oil recyclers if you know them. But most of them give it away to a local mechanic. Or you can take your bike to SVC tell them to drain the oil and use the oil which you've bought and they will take care of the old oil and ship it back to recycling companies. But all in, it's not a big deal.

What brand you use? If it happens to be Shell and you have a shell fuel station nearby they should take the old oil.
I used to keep a bucket full of mud in the backyard and pour the oil in it. I gave up this habit off late and now give it to friendly mechanic.

I use the Honda motor oil which is available at the Honda SVC

Re: Engine Oils

Hi friends I use M 5100 completed 4000kms as I have done two long trips after 1st service which was done at 600kms planning to change oil is it correct to go for oil chance are still I took time for it

Completed 4k kms on M 5100? If yes, you surely need to change the oil.

It is indeed the right time for the oil to be replaced. At max I've extended to is 3.9k. But since it being a new bike, I'd recommend you get it changed in the next service.

Re: Engine Oils

I carried out some research on the net regarding engine oils from forums incliding but not limited to bob is the oil guy and carbibles. The idea that truck oils have very long lives can also be attributed to this : for most part trucks and other long haul vehicles are running at steady speeds for extended periods of time. This means that after start, once the oil heats up to temperature, it gets to stay at that temp for a long time and work its magic. It is also noteworthy that by the nature of long haul operattions, the oil stays at a particular temperature for long time. This make prediction of lubricity properties easier. Thus oils for trucks can be designed to last longer due to consistent parameters they are exposed to. Now when you look at motorcycle operation in indian conditions, the running is generally stop-start in nature either due to short duration of travel or due to frequent traffic stops. This exposes the oil to a wide range of operating temperatures and causes increases breakdown of VII Or viscosity index modifiers that make the oil multigrade. As soon as this happens, the oil needs changing, as it ceases to be a multigrade oil.In case of synthetics this wear and tear is offset by virtue of chemical design of the oil, which means extended drain interval for the user. In any case because of the nature of two wheeler usage (or for that matter car usage) oil drain intervals should be those that the OEM recommends.. An exception to this would be bikes or cars that are used for touring (long haul).

if you want to use for a 15 min ride at low speeds... Yes, you can put a 10w30 in a 20w40.. as the oil will not thin to w30 viscosities and you will shut diwn the engine.
But i didnt get your point.. You are stopping riding because of rising petrol prices and trying to put a 300 rs oil.. Why not a 20w40 mineral of 220 bucks and ride a complete 3000 kms on it.. And the money you save(rs 80) is good enuf for 10 litres of price hike in petrol..

Guys i have some good info for you..
I have found an oil which you can keep for more than 10,000 kms in a motorcycle.. (gulf 4t also claims tne same).. Actually you can keep this oil for 700 hours.. i.e if you move 25kms in an hour, you can keep it for 17500 kms!! Its really hard to believe but this is what is proven on heavy duty diesel engines.. It can even go to 900 hours operation in these high temperature furnaces like engines.
The oil is called Mobil Delvac Super 1300. For heavy duty diesel engines. Also qualifies API SJ ratings for petrol/gasoline engines. Though one would say its not JASO qualified.. But it can very well be used in motorcycle engines as no friction modifiers are added..
There are numerous bike owners in the US who use this oil in their motorbikes and no complaints whatsoever.. I have bought a five litre can for myself and will be testing it next time.. The listed price was 1455 but i got it in 1300.. Comes 260 rs per litre...

Its known as the million mile oil !!

Some reading needs to be done here
mobil delvac 1300 900 hour - Google Search

Also read the comments of experts on this kind of oil.. Especially Mobil Delvac 1300 Super.
Motorcycle Motor Oil

Any comments?
