Engine Oils

[pioneeraron]

You got it wrong. Pinaki is against 5w40's 10w40's quoting them as too thin and thin oils can't provide lubrication. But that so called thin viscosity is measured at 0 degrees and as the temperature increases the viscosity increases and meets the required ratings.

Today got shell synthetic 10w40 from distributor and got discount of "Rs.205"
MRP is 755 bought it for 550. Retail price at another shop is Rs.700. Attain dealership for these oils and open 2 or more retail outlets would make a great business I think.

Hey buddy i was toking about cars not bikes since innovas topic came out I know for bikes it should be 10w40 or higher grade.

Hello folks,

I have an Aquila and was wondering what kind of fuel additives do you use if any and if you add anything to the oil system? I am using synthetic oils, if that matters.

In cars you have System G/Sonax that help clean up the injectors, but the Aquila is a carburetor version and I wanted to be sure before I put in anything into the fuel.

What are your experiences in using additives for fuel and the oil?

Thanks

Funnily enough the 5w40 was recommended by the Yamaha guys , On asking them about the recommended grade being 20w40 , they said not to worry and it would not cause any harm ... I believed in that and also the bike is showing absolutely NO problems with acceleration , speed or no roughness whatsoever up until now ,

I've got worse advices from Authorised Service Centres of various manufacturers over the years . You've to keep in mind that in all probability these guys have never attended a primary school even , at least certainly not the proprietor of the establishment . So always evaluate their words with your common sense and confirm with the little booklet . This not to say that they don't come up with really good ideas , occasionally .

Hi guys,
I've done wit my 3rd free service,the problem i'm facing now is the engine is getting over heated & the noice coming out from the engine is very crapy.
since i was using the Bajaj DTSi oil..but now i've shifted to Motul 5100 Semi Synthetic Oil...The bajaj service mechanic is telling the oil is not suitable for ur bike. so please continue wit the bajaj oil...so plz tell me wat to do..
Regards

Semi-synthetic oil isn't called for at your 3rd free service . You should have stuck with mineral only , and pressed on with Bajaj to solve your problem , as it was .
A Bajaj mechanic saying that Bajaj oil is the best in the world at a Bajaj Service center is surprising ? Hero Honda voids your warranty if you use any other oil than HeroHonda 4T !!
Ask that same mechanic to re-fill with bajaj oil , with guarantee of no further problem with the bike . Then ride on him untill he solves it ! Don't forget to get his personal mobile phone number .

Why do you want additives ?

Keeping the carbs clean and oil additives to ensure lesser carbon sludge?

additives (atleast which are available in india) dont work.. Its proven.
So just change your oil at regular intervals & get your carb get cleaned whenever needed.

Yes , I get you -- with poor quality and sometimes stale fuel we get here there isn't any option but to clean out your fuel system including the carb manually from time to time . You can try acetone in your petrol - 1-1.5 ml per liter . Start with 1ml and increase untill you find the optimum for your engine . Some people here have reported good results from a few tankfuls of premium petrols too .
Frankly speaking - engine oil additives/flushes don't work very well and can cause even worse trouble for you by dislodging the dirt and blocking up an oil path inside the engine . Use good full synthetic oil changed early (half the usual recommended kms) if you suspect sludge in the engine . Complete solution is an overhaul .

Murali'jje , it's impossible for anyone to diagnose the problem, if any, without personally experiencing the noise you speak of . It can be so many things ... or just normal ... motorcycles are naturally noisy machines . You'd do well to consult the senior-most mechanic or service-engineer of Bajaj service center .

[maverhick]

When it comes to cars, there are quite a few options that do work. For ex: System G/D for cleaning up the injectors and a couple of other additives that do work. I wasn't sure their equivalents were available in bikes and looks like they aren't.

Thanks for clarifying. I'll use Synthetic oils and change em often. Once a while carb cleanups are good with me as well.

Any leads on how any of you have handled rust in the tank?

The basic difference is bikes have a very small oil sump , narrow oil paths , marginal oil pumps , runs the same oil thru the transmission & clutch ( thereby by chewing it off quickly) and depends critically on the oil for it's air-cooling and you can't even take out the oil-pan bottom under the sump to empty it fully ever .
But don't get me wrong - many products are available specifically for bikes and do work well too .. but in case of a real problem , I feel that it would be simpler to overhaul , bike engines are less complicated and way less cost to do .
It depends on which tank you are speaking of . If a fairly popular vehicle .. replace the tank .. it would cost between 1000 Rs to 3000 Rs only . If you want to keep it .. there are methods ...

And since you seem experienced with cars - please don't go use a synthetic ( or mineral ) oil meant for cars in your bike .

[maverhick]

Gotcha. Wouldn't use a car oil in a bike and vice-versa. I have an Aquila, so changing the tank would cost anywhere between 15-20K, I did read up electrolysis, so that might be on the cards sometime to get the tank back into pristine condition.

As for draining oil, I think it is possible to drain all the oil out of this bike, the oil drain plug is at the lowest point in the bike.

Guys, where can I purchase Petronas FS 10w-40/30 in Bangalore, and what is the current price? TIA

[rohan_5013]

Hey guys,need your help after a blunder I made
I switched to agip FS 10w40 for my Fazer and after it hit minimun mark,I topped up with the same agip FS..only now do I realize that it was actually agip FS 20w50 So my bike has been running for the past 4k kms with a hybrid of 10w40 and 20w50..I still have about 180ml of the 20w50 left..I have got the 180cc big bore fitted from Joel and he told me not to use any thin oil like 10w40 etc. so I am planning to change oil as my run-in is complete.Should I buy another 1 litre of 20w50 agip FS and use the remaining 180ml too as I am going to change the oil filter..the quantity required is 1.2L..waiting for help
Also I would have 1.18 L and not 1.2 litre..will that be a problem??

[Honda_CBF]

Using 1.18 liters instead of 1.2 liters won't give any problems.
But how can you use any oil without looking at it grade??
And I've heard FS oils are not good for running-in.. Was it recommended by Joel too?

I told Joel that I had FS oil at the time of running in and he said that it was fine..from now on I should not be using the stock recommended oil I guess..as my bike is 180cc now and requires thicker oil..another Fz owner nand is also using 15w50 grade oil in his bike..hopefully everything will be ok..

[Honda_CBF]

^^ok then. According to an article on internet FS oil increases the running in period because of its great lubrication qualities but causes no problem.
And change your oil to 20w50 or atleast 15w50.
Btw, I'm also inclined towards thicker oils.
Happy biking..
