Engine Oils

Re: Engine Oils

My friends are running their bikes with low engine oil. The bikes are stunner and apache 180. What grade is recommended and where can I get genuine motul near pathari palam in cochin. (I am thinking of motul 3100 gold). Please suggest any other options, if better for these bikes. I am planning to change it by tommorow.

Re: Engine Oils

Petrol oils can come with detergents too... It's all dependent on the specific oil. The argument about breaking up helpful carbon deposits Applies to switching to synthetic oil too as it has the same effect. It will only effect your compression if your rings are shot and not doing their job....

The specific diesel oil I'm going to use carries an API SL specification....

Re: Engine Oils

Using a diesel engine oil on an engine around 40k to 50k kms for 100kms is ok since it acts like a flush on engines that have run with old oil a lot or have been standing with oil for long and have likely deposited carbon and sludge.
Usually well maintained engines do not need flush etc.
Problem is somtimes carbon deposit is important for an engine to keep compression
A flush or high detergent carbon cleaning oils such as diesel engine oils can make them loose compression.
If you really want to experience a car oil use a petrol one without any friction modifiers .(additional friction modifiers will cause clutch slippage as we use wet multiplate clutches)
I have been using one for around 4000kms noe, shell pennzoil 15w40 I think,
Pretty good, not loosiing its viscosity yet. But i feel it takes a little longer to heat up than 20w50 and feelS thicker.

There are many xBhpian's who have been using Diesel oils in their respective bikes since long period. They are happy with it. Infact, Diesel oils are a tad better than normal bike oils. [MENTION=47074]Divya [/MENTION]Sharan has been using the same in his bike.

I did not understand, how will carbon deposits help in keeping the compression? What compression are you talking about?

Cheerz!!

Bro, Diesel Engine Oil will have API specification starting with "C". It will be like API CH4 / API SL.

Cheerz!!

Which oil is that?

Old engines have a little worn piston rings etc and little cracks and internal fissures.... carbon deposits help fill these holes and in old engines flushing etc causes loss in compression.

Which diesel oil are you using bro I will give it a try too I am using shell pennzoil car oil its a blessing! And damm cheap too for a ss oil I think.
I am afraid using a diesel oil because I hepave read they have very hogh detergent quantity since obviously they have to clean up deposits from notorious diesel oils......

Ps my ebgine is now 79+k kms old

Re: Engine Oils

Most of the modern engine oils (either petrol or diesel) have friction modifieres, this can contaminate friction linings, like your clutch, and then you will notice clutch slippage, the basic difference between diesel engine oils is it's more alkaline, due to the more acidic nature of the combustion byproducts, but there is also a catch to it, your vehicle clutch will only slip if it is worn out the oil only brings that problem to your notice, you can use more alkaline oil as long as your clutch is ok, Mobil delvac and shell rotella (15w40)are very good oils.

Those two are the most discussed DEOs for motorcycles on Internet.

Any independent/proprietary authority to stand by them(DEOs for Motorcycles) with long-term test results?

Exactly... API CH4 and API SL. My point was that its specified to meet the petrol standards as well as the diesel ones.

The one I'm going to use is Caltex Delo 400, cause a lot of guys here have used it in their bikes over long periods and are happy with it. I've used it in my diesel hilux before, and my father in law uses it in his petrol Camry.... It comes in big drums and costs 1/4 as much as motul... So it makes a lot of sense to run multiple vehicles on it, but I wouldn't be doing it if there wasn't plenty of people testing it and saying it was fine.

I believe they are the most reputed companies in the engine oil field that's why they are more prescribed, but there are other brands also which are equally good like Schaeffer oil, Valvoline premium blue,Caltex kixx dynamic gold, i think its just that which oil a person feels better with.

Im still a bit scared to use diesel oil in my engine.... its quite old you see. The piston rings wont be what they used to be.... il use a car engine oil for now but maybe when andni I have to do an overhaul il go with a diesel from the start.
Now using a car oil I feel its better than motul 7100 in turms of smoothness. Motuls a great oil no doubt but this is so much cheaper. Its weird.

The major problem you might encounter by using diesel oil in an old engine is of clutch slipping,the problem arises with the viscosity of the diesel engine oils, with the higher viscosity first problem arises is of heat generation due to friction created by moving of the fluid inside, the thumb rule is that with every 8 to 10 degree increase in temp. the engine life is cut into half, the second problem occurs in winter becuase of higher viscosity the oil it will be difficult for the pump to rotate the oil to essential parts hence metal wear will occur due to nonavailability of the proper lubrication, but still there are lots of peoples using diesel engine oils in there cars and are quite satisfied with it.

Re: Engine Oils

I have a pulsar 180 ug4, 14500 on odo.

For the first 10k kms i used bajaj mineral oil 20w50, replaced at 3k kms interval each time.

At 10k i put in motul 5100 15w50 ss, results are good, ie smooth ride, no engine noise, no stalling at higher gear with low speed, etc.

So should i continue with this one or upgrade to 7100 15w50 fs?

Can the bike hold the fully synthetic oil or can there be a leaking problem?

You can go ahead with the fs oil but imo its not worth it. Stick to the 5100 15w50 motul. Theres nothing like it. Perfectly priced and lasts good too.....
The difference between 7100 and 5100 will be neglegeble in your day to day running. 7100 and 300v are an overkill for day to day runnings.
Also fs oils will have a tendency to vaporise and drop in levels after a long highway haul or in bumper to bumper traffic. You will have to buy extra cans to top it up after 2000kms or so as seen in few bikes. Stick to the 5100 ( I would have done this)....
