Re: Engine Oils

The international manual doesn't specify any brand of engine oil. Some owners have changed to Motul from the SVC itself. I myself have changed to Motul 7100 10w50 after the second service(did the oil change at home). The difference is radical and is felt precisely in the 4.5k to 5k rpm range which is known for the infamous vibes. The choice to change is yours but maintain the viscosity rating unless the ambient temperature is very high.

I'm so confused with which oil to use after my warranty comes to an end. A lot have recommended release-on, though many have also vouched for Motul 7100. Is 7100 really that good? I think this thread itself has said that it's only good for the 1st 1000kms or so and then isn't much different to Bajaj oil.

Also, the 7100 is manufactured in Vietnam and France. The original oe from France seems to be a winner here, but the Vietnam one isn't great. Which one have you used?

Re: Engine Oils

Would recommend sticking to the bajaj oil atleast for the period of free services for warranty's sake. Even post that, most domi owners seem to like the Bajaj oil. Motul doesn't agree with some domis. Bajaj oil seems to work well till 5k+- kms roundabout. Flushing is not required for every oil change even with a grade change for a new vehicle. Once a year is more than sufficient same as injector cleaner. Is 20w50 recommended for domi anyway? The clutch/engine will be more sticky due to more viscosity. Please have a look at the viscosity table of 10w50 and 20w50. During summer 20w shouldn't matter too much. But stick to 10w for rest of the year.

Warranty for the Domi is 30k or 2yrs. So for warranty sake, use the Bajaj oil for that duration. If you don't care about the warranty, then you can change it.

FYI - the jury is still out on whether Bajaj oil is mandatory for the warranty but few rides in BLR ran into trouble while claiming it.

Remember this. Flushes aren't required always or every time once one changes the oil. Flushes are required for old engines or engines that have been run over 20k plus. Even at this, flushes are recommended to use only once and not every time. See, oil itself gives a sort of protection layer inside the engine parts which is vital. Flushing each time removes this sort of mild layer that is vital.

The oil sold by Bajaj Under the 10000 was literally snakeoil that had a best life of 2k max which was manufactured by HP. The newer ones made by Total and good, being fully synthetic they can be extended to 1000 kays more from the 2k. You can use both oils with no problem whatsoever, and no flushing is required. One thing to keep in mind, in case you top-up, make sure you the save Valvoline oil and the same grade.

Hi, thank you so much for such detailed replies [emoji4]
Like I've said my bike is due for 1st servicing, will get it done once it touches 500 KM and even though I read positive stuff about Bajaj 10W50 FS Oil am yet to experience it. Also, am aware that my bike's warranty will be void if I use different grade/brand so I'll be changing oil myself at home once I clock 1000 KM. As far as grade is concerned I've nothing against the recommended 10W50, it's just that since the engine is new it heats up real quick and then feels a bit coarse. So, I feel that for now slightly thicker oil might be better and the reason why am going for Valvoline 20W50 SS is coz I already have it. All I wanna know is whether I can change grades straight away or is there any process involved?

Re: Engine Oils

Guys, am gonna take my Dominar for 1st servicing at 500 KM this Monday. If am not wrong then Bajaj SC will use 10W50 FS oil made by Total. Now, just to be on a safer side I would like to drain and pour fresh oil again at 1000 KM. Now, I've access to two cans of Valvoline 20W50 Premium SS API SN Oil so can I directly use them or I'll need to flush engine and install new oil filter as am using a different grade?

Re: Engine Oils

Is 20w50 recommended for domi anyway?

Bajaj recommends it's own 10W-50 for Dominar. That bottle claims it is 'fully synthetic'.

Re: Engine Oils

300v is a racing engine oil. It is designed to provide best performance over a short interval. It is not that it must not be used but its life is just one half or one third of 7100. If is good for someone who keeps the bike at high RPMs and ready to change oil every 2000 or 4000 kms (in air and liquid cooled bikes respectively).

Rightly said.

[AP_SF]

Re: Engine Oils

Anyways you should change engine oil after 4000 kms. And if the bike is 310 cc. He must be revving high. Also the torque generation shall require high rpm around 10000 may be. I am regularly using Motul 7100 10w40 for CBR 150 from last 4 years, which hardly last 4000 kms. My daily commute is 50 kms and in Mumbai's heavy traffic.

Thanks for the suggestion. Sadly I dont rev very high all the time because I get my sweet spot of power and speed in just below 5k rpm, so I never needed to rev high to enjoy.
I do agree about changing the oil at sooner intervals though, even I think TVS's suggested 10,000 kms for RR 310 that too on Motul 3000 4t plus mineral oil is bit of a stretch.

Re: Engine Oils

Hi There,
You can go for Motul 300v 15w50 thats the best for engines above 300 cc.

Re: Engine Oils

Couldn't find motul 7100 15w50.. so bought 10w50 instead for RR310..

Re: Engine Oils

Both have similar viscosities both at 40°C (120.5 and 126.5) and 100°C (18.1 and 18.0). So you should be fine with the 10w50 oil. For more details, just google Motul <oil name> XXwXX specs.

Okay Thanks. [emoji16]
