Re: Honda CBR 250R

Which shell fs to use ?

I see the following on their website :

1. Shell advance AX7 10W-30, 10W-40 & 15W-50
2. Shell advance ultra FS: 10W-40 & 15W-50.

Re: Honda CBR 250R

Hi,
i believe you have misunderstood what i was referring to. For your future reference: FS oil is nothing but a short form for 'Fully Synthetic" engine oil

If you have visited the Shell India website:

1. Shell advance AX7: is a semi synthetic/ SS oil
2. Shell advance Ultra: is a fully synthetic engine oil and it meets all the specifications required by Honda.

The recommended one is the 10W 40 grade. Here is a picture of the bottle for you to identify it easily:



Hope this helps..

Cheers,

Re: Honda CBR 250R


I am aware about SS and FS. But was confused hence the doubt.

Will feed my baby with shell FS 10W-40 in a Weeks time.

Cheers,
Sanjay

Re: Honda CBR 250R

What are your thoughts on Motul's 300v? I too have been using Shell advance, but moved to Motul this once on a friend's suggestion. I have nothing to complain about Motul, but somehow feel that the harshness in the engine has increased... Might be just me being paranoid?

Re: Honda CBR 250R

No...If you had used Shell FS Ultra, then Motul 300V will feel harsh...CBR250R and Shell ULTRA FS seem to be "Made for Each Other". Repeated use,actual real time test etc., all point to the fact that the Shell Ultra FS is better than Motul 300V for CBR 250 R.
Regarding Engine Oil Consumption , the accepted normal amount for a Single cylinder 4 stroker is 2~3ml of oil per liter of petrol used. Anything above is an indication of oil leaking through Compression ring into combustion chamber....This can also happen IF the Engine Crank Case Breather Tube is blocked, leading to engine crank area pressure builds up above normal and pushes oil past rings into combustion chamber.
Regarding FFE , it will allow exhaust gas to flow freely(depending on design) and allows for better power at top end. Down side is, because of free flow without back compression, the inlet charge will leak into exhaust during Valve Overlap, leading to Reduction of Power Due to Lean AFR and Higher Engine Operating Temperature at Low to Mid RPM.On a street bike meant for everyday use FFE change alone, will cause more problems to engine parts and less FE.

Re: Honda CBR 250R

Right on! Yep, I was using the FS ultra! Would this also ne the best option while on highway runs in excess of 1k kms? I decided against the FFE as well, based on the impractical usage in current conditions. Thank you [MENTION=32286]psr[/MENTION]! Would like to talk to you more about the bike so as to understand it better! 😁

Re: Honda CBR 250R

Shell ultra FS has been tried by many CBR users and proven to suit the 250 very well.
Its my observation that the oil in fact smoothens engine noise and vibrations as its reaches its optimum temperature.
Riding in second gear for around a km to let it reach working temp. gives a very smooth throttle and roll on response too.

Re: Honda CBR 250R

shell has been serving very well in cbr250's across our country and some serious mile munchers are pretty happy.
i have clocked over 30k running shell itself on my CBR and its the best oil for cbr250 you can get.


1k kms ? thats bout it ??? it can take a lot more...

Re: Honda CBR 250R

Thanks for all the suggestions regarding my concern.

I got the 3rd free service done yesterday at 9900kms (4000kms/6mnths after last service). The engineer checked for any possible leakage of engine oil and found none. After a thorough check-up, he suggested there is no cause of worry but just to be cautious, I should keep an eye on the engine oil level for some time. 1.5L FS oil was filled in my presence. The clutch switch was giving a little problem while trying to start the bike in gear, so it was lubed and works well now. Oil filter and air filter were changed as part of the service. The chain was well tightened, cleaned and lubed, and I was surprised at the amount of time the engineer spent on the job. Whether it was because of my presence around the bike all the time or he normally does it this way, I was quite impressed with the way he was checking up on everything that I had listed down on the job card. The footpegs and handlebar were tightened as they had started to vibrate a bit on high speeds.

I've ridden the bike for about 120kms post service, and there is noticeable change in its behaviour. It feels much smoother and faster through the RPM range and the vibrations are also much lesser.

I am planning to head to Ladakh this June and will get the brake pads and tyres changed before the ride. The brake pads still have another 2000kms left in them, so a part of that will be used for a small weekend ride in the coming days. For tyres, I'm planning to buy the Michelin Pilot Street.

Anything else that I should check/change before the ride?

Re: Engine Oil Vanishing!

By tomorrow, 52000+ Km to precise since my CPR is running on Shell 10W40 Advance Ultra

Re: Honda CBR 250R

Excellent insight sir, and as always. I can second the notion of the 300V being felt harsh. Using the Shell on my Victor (AX5) I can vouch for the difference it made. 300V being used on the 220 after a few hundred KMS I can clearly feel the kitchenware rattle, and then to Delvac to history.

Blade is running on Motul 7100 for now, will be getting Shell AX7 Ultra when she's due for next service, why separate the "Love Birds" when they are made for each other [MENTION=32286]psr[/MENTION] sir.

Cheers!

Re: Honda CBR 250R

Ot, but is shell oil good for rc 390?

Re: Honda CBR 250R

almost all ktm owners 200/390 i know swear by motul 300v. i would suggest to stick with it...

Re: Honda CBR 250R

Hope I can butt in here. 300V is a good "substitute", I've used it both in my Duke 390 and 220. Though I've never faced any performance issues per se, but the engine went a little harsher post 200 kms in a stretch on the 220. Cold performance was very good, and personally didn't get the feedback I expected from 300V apart from improved gear shift and bassier engine note. It's very effective for track days where the engines are stripped down anyway pre and post race, but for the price to value, especially for street use, I don't think it's a good choice.

7100 and 300V are ester based, but the detergecy levels between the both that makes the difference. Personally 300V is history for me. 7100 is much practical and lasts longer for day to day use.

Currently 7100 does duty in my Blade. And performance is nothing short but very satisfactory. Next up I'll be switching to Shell AX7 Ultra and see how it fares.

ynike, Shell comes in w40 in the range that's sold in India. 390 uses w50 spec for a reason, to cope with the heat, I'd stick with that rating for better engine efficiency and overall performance.

Re: Honda CBR 250R

300v has this characteristics of being harsh for the first 800-1000kms ( point where most oils lose 40-50% of life ). After 1k kms, the oil will make the bike butter smooth and you can rev it all the long till 4.5k kms ( MAX i have done on 300v. It can last for 6k kms but i don't want to take risk riding at high revs most of the times and at higher ambient temperature in chennai ). So people who are coming from different oil think its bad and they change it :/ Yes, its not value for money.... But for people who like to keep their rev needle near redline most of the times, its the best oil you can get Remember,you have to be patient for the first 800kms even if you use 300v regularly.
