Engine Oils

[Honda_CBF]

After clocking 17K on Pulsar 150cc ug3, I want to try motul 300 V. I read so many good reviews about this oil and just want to try how my bike will behave. My question is should I go for 10W40 or 15W50? My manul says 20W40 but as most of you know bajaj now recomends 20W50 for dtsi bikes with higher CC engine. Please help me to decide. Thank You.

you can use both the available grades, no harm. Just keep the oil level checked all the time because it can disappear from crankcase. In theory, xxW50 will burn less than xxW40 but may decrease your mileage by 1-2% compared to xxW40.
And if I were you, then I would have used 15w50 for the very same reason.

I would suggest you use xxW40 300V. I've been using 15W50 300V since the last 1000 kms, its been raining here and the bike takes 3~4 cranks to start the bike in the morning and the revs rend to drop during idling.
If you live in a place where the temperature drops low during winters I'd suggest you stick to xxW40. Rest is upto you!!

Stick to xxw40. the 300v may cause a leakage at teh head & you might need to replace the head gasket. Why dont you try the shell AX7 or ultra.
I have used it on the p150 and i feel its really good. And you can get them from the shell bunks.

hi
recently while purchasing oil i asked the dealer if there are any synthetics with him and he show Agip oil named 4T fury 10w40

http://www.aparchematek.com/Products/Two%20Wheelers_Synthetic%20Engine%20Oil.pdf

labelled as synthetic

can anybody tell me is it really synthetic and how to rate agip brand with others

[tomjo]

guys,i used motul ss 5100 oil after 5k in my p220 dtsi.now the bike has done 800 km and the oil level decresed i mean its not up to the level (not so low ).i bought 2 bottles.so my question will it be harmfull to my bike if i pour the new oil to the existing one ?

AFAIK oil topup is advised in regular intervals. so topping up with new oil should not harm the engine.

Try 7100 FS for your machine..

I would suggest you use xxW40 300V. I've been using 15W50 300V since the last 1000 kms, its been raining here and the bike takes 3~4 cranks to start the bike in the morning and the revs rend to drop during idling.

Its not temp related.. some other problem. Give a little throttle during cranking.. You will waste the engine by continuous cranks.

As its API SM.. it should be a good oil. Whats the price?? Anywhere near to Motul FS oils will undermine its usability.

My recommended grade is 20W40 but I'm using 300V 15W50 & that's the reason for the cold starting issue, 15w50 is thicker than 20w40 at NTP.

mrp is 410 but final price from him is 325

If anyone here experience Vibration,Noise ang more engine heat and louziness(when drive in long travel) using 10w40 or 20w40 grade in their bike who has a recommendation of 20w50 oil?

Cold start issue for using 15W50 instead of 20W40? At cold, 15W50 is LESS VISCOUS (flows better) than 20W40.


All oils only lose viscosity with increase in temperature.

[FranklySpeaking]

Hmm ok. Keeping the grade (20w5O) same i can top it up with any other oil (other than motul ) of the same grade ? Does it mater if i use Semi-synthetic or mineral oil to do a top up (the synthetic oil)

It is better to not mix oils. All companies do not use the same additives. You will understand what I am saying if you understand a little of chemistry.

[FranklySpeaking]

Guys, Apache 180 uses 10w30 TvS Tru 4 ...

Can I change it to 10w50 / 15w50 Motul ? ? ?

Bike ODO - 5.1k

Why do you want to do that? Better stick to company recommended grade only. And, which company have you seen selling 10W50 in India?

When using mineral oil, it is better to use oil that has lesser difference (called spread) between the number before and after W. I read somewhere that 15W50 oils normally start behaving like 15W40 oils within 1500-1600 km of use. So, use them if you are going to change oils soon. 20W50 will maintain its viscosity for longer running than a 15W50.

Ofcourse, everybody knows that 15W50 viscosity is better suited than 20W50, but practically, because of more shearing in case of 15W50, 20W50 is better and that is why most companies make 20W50 and not 15W50 when it comes to mineral oils.

Synthetic oils are different game altogether.

seems to be a very good deal!

yes. Have used 5w30 and 5w40 grades in my car.. the noise was like something rattling inside the engine.. Will never use w30 again.

not necessarily.. At RT a w50 will be more viscous than a w40. But as Motul 300v 15w50 is a synthetic, it should flow faster.

completely agree with you.

Argument favoring 20w50 in place of 15w50 is true but outdated. Previously 15w50 were made with more VIIs than 20w50. But nowadays 15w50 SS have equivalent VIIs to 20w50 mineral.. You wont find 15w50 pure minerals in the market. API SN 15w50 will be pure fs oils.. Thats why its always better to use higher API rated oils. The higher the rating the better the quality of oil.(except the zinc and phosphorus content which is being reduced, it woukd be better to use these high quality oils + zinc and phosphorus additives separately)

@ Frankly speaking & muztariq,
motul says its ok to mix (any) oils with theirs. 'No harm' but definitely 'performance' will change but difference is hardly noticeable.
And 10w50 fs is available from castrol down here.
@ andrei,
using below recommended sae rated oil will and is known to show symptoms you stated plus, it will cause accelerated wear to engine components. Though still there are people who enjoy their rides with lighter oil. But if you ain't getting good feel then revert back, ASAP.
