maybe WOLS.... anywan noes.... ?

Technically, it is not recommended.

Personally I have used Mobil 1 in bike, and it didn't seem to give me any problem. However the side effect could have surfaced later which I am aware of, as i have sold the bike

i think the velocity in the oil is different. like sw20 50 wadeva..do a search on wikipendia. but common sense will tell u, cant use medical lotion oil for cooking oil can you ? wouldnt wanna mess up my bike with oil made for car instead ! ^^.

[GuiNNeSS]

car oils come with friction modifiers ...screws up ur clutch

 

and car oils are not meant to be revved to 10k RPM or more typical or bikes

 

correct me if im wrong

[mepkoh]

its no no....dont use..

[stsoh]

u can use motor (car) oil if it has API grade 'SG' or 'SH'.

 

reason:

after API 'SH', oil manufacturers replace ZDDP with friction modifiers.

there is concern that zinc and phosphorus emissions could damage catalytic converters.

 

u find on the shelf the current latest API for motor (car) oil is 'SM' or 'SL'.

some motorycle oil u might also find API 'SJ'.

most motorcycle manual recommends either API 'SG' or 'SH'.

thank you St Soh, have been reading your posts on the roadwin for a long time now. to hear from the guru himself.....so happy.... thanks!!!

i seen my fren using it for his bikes...

using shell helix one

[FUphan]

I am riding a phantom 200, tried once using car's engine oil (idemitsu fully syn 5w-40) for my bike full 1 litre which was leftover from my dad's car. Power is sluggish, engine get noisier but one thing I notice is that the gear change is smoother. It could be that the oil is too thin for bike's use. I am currently still using it, but only as a "top up" as phantom tends to eat up oil. Been doing that for a year liao, bike's still running well.

[mepkoh]

the first thing whats the differnce in a car/bike??

 

the 2 /4 stroke engines design has been used for cars and bikes..

 

the major difference as far as EO is concerned IMHO is

 

1. EO is blended to the application of the engine..

car rpm 8000, bike 12000 is not uncommon.

What this means is that the at higher rpm frictional forces are much

higher (how high you have to ask the bearings/oil expert)..so the oil has

for bike hase to be blended differntly from cars..All this is done is to

make sure your bike/car can reduce the amount of wear and tear to an

acceptable rate..and at the same time to reduce the maintenance cost to

the minimum...ie would you pay more $$ for your EO, when you know a

much less expensive EO can do the same job??

 

2. The cluch mechanism in cars is housed seperately -isolated from the crank housing by means of a oil seal. That is to say the lubrication oil for the engine and clutch mechanism are physically seperated and of course you can use seperate diffent kind of lubrication oil. As for most bilkes the engine and the cltuch shares the same EO..

 

the clutch mechanism as you know consists of gears and more gears...

Geras are known to have he most intense frictional forces acting on them.

So for cars they have transmission oils..The transmisiionof power is by means of a DRY clutch...so you see the trnsmission oil do not gets into the clutch. So the oil experts add what is known as friction modifiers to the blend.this are slippery stuff. this slippery stuff is also added to the car EO.

 

on the other hand Bike Clutch mech and the engine are housed in the same housing or crankcase and use the same EO for lubrcating the engine and the clutch mech. bike use a WET CLUTCH system. So if you use CAR EO which have friction modifiers in them, the slippery stuff in the EO may affect the efficiency of the wet clutch..eg.. at high speed you may have cltuch slipping..ie when you rev your engine but the bike does not seem to go any faster..and the worse part is after prolong use the clutch will be damaged.

hey it is xxx to replaec the clutch.

 

So you see my friend..bike stay with 2t and 4t oils...stay away from car eo and transmission oils..

 

Japnaeses lab..have a std...JASO MA...if you see this , it means the jap has certified it for use in bike...At this moment only jap std..has this certification of frictional modifiers in oil..other european american lab has no such certification (correct me if i am wrong).

 

those who use Car EO ...will suffer cltutch deterioration in their bike..they will not see an immediate degradation...but it will happen...

 

Take care...dont be a guinea pig....the oil companies knows what they are doing..

[motornewbie]

hmz can i add on smth,can car coolants be used on bikes then?

[mepkoh]

hmz can i add on smth,can car coolants be used on bikes then?

 

 

i suppose you can.....that is if u want to be a guinea pig...

but in all practice..the question is how much....?? a small percentage i dont see any problem..

but it is best not to.

nowadays all sort of blends are in the market..test have shown that some oil do not mix that well with othres.....and this will cost you$$$$$$$$$$

if your bike is "old" as in milage ...dont use those synthectic stuff...and never use EO meant for diesel engines.

[mepkoh]

car coolants..yes of course....the bike and car cooling system similar

Hi,all the while im using shell Ultra 5w-40 for my R6,cbr600rr6 & R1 & yet no problems afterall,the only problem is the bike feeling smoother & lighter when moving off & pick up hehe,if im not wrong the clutch will wear off faster cause of the grade im using.

 

2003-2005 R6-03 sold

2005-2006 CBR600RR6 sold

2006-2007 R1-06 sold

of course with the friction modifiers in the oil...it should have better gear change..and engine runs smoother...but at the expense of the clutch...

 

hey ...you ride fast bike...why dont you test out with 4t oil..i am not surprise that the top speed will be faster than what you are using now...

 

the following is an example of 4t oil shell advance 4t:

 

Shell Advance Ultra 4 is a unique fully synthetic lubricant exclusively designed to provide the ultimate in engine protection, cleanliness and superior clutch and gearbox operation for high-powered performance motorbikes

It is the best Shell 4-stroke motorcycle oil available

It is the perfect choice for riders who demand top performance and push their bikes to the limit and also for urban and city bikers who rely on their machines day-to-day, as it protects against the extra engine stresses caused by today’s stop-start traffic environments, keeping engines cleaner for longer

The balanced friction technology used provides quick engine response without clutch slippage for smooth gear shifts and easy starting

The best engine oil for modern, high performance bikes used in racing or high speed, long distance riding

The technology has been proven in race and endorsed by leading motorcycle manufacturers, Ducati and KTM, and has successfully been used in motor sport (WSBK, World Super Sport Championship, World 4T Enduro and Moto Cross Championship)

It exceeds the requirements of international specification (API - SL and JASO MA) and all Japanese and European motorcycle manufacturers

 

 

SO you see...Shell has a 4t oil for high perfomnce bike,,good luck on your use of car EO.....

[Arcfire]

Well, after all this discussion, it does seem that if you have a dry clutch bike or a scooter which generally has no clutch to be lubricated, car oils have no problem being used as long as it has the specific ratings.

 

But is it really any cheaper?

Tks for the info bro,might try ur method after my MV is out.

[mepkoh]

pleae note the JASO MA certification for 4T oils...

and this staement..

The balanced friction technology used provides quick engine response without clutch slippage for smooth gear shifts and easy starting..

 

the above is copied from shell website..

[mepkoh]

i suppose car EO is cheaper....compared to 4t oils..as the 4t oils are blended for higher frictional stress level than cars....

 

Well i have not herad anyone use 4t EO in cars for a simple reason they are expensive stuff (compared to CAR EO)

[mepkoh]

i buy my car EO from giant..they have this mobil 1.super syn..15w55,

for less than $60/4.75L...at esso/mobil Station they are asking for $111/bottle..this is the most expensive car eo offered by mobil.

 

of course i use it in my car....

 

any way 4t always sold with 1L or ssmaller qty........some even paid up to $28 for a bike eo service..

[Wormz]

hmz can i add on smth,can car coolants be used on bikes then?

 

can i add on something oso? Can car engine oil FILTER be used on bikes? I got a suzuki car filter that is cheaper than suzuki bike filters...

[iCeLkipS]

I have been using car's Shell Ultra 5W-40 on my KIPS. Frankly, the transmission are better compared to 4T bikes EO.Well, if its just meant for lubrication to protect metal while rubbing other metals, then I dont see the danger. Even using normal 4T EO for bikes also, I suffer clutch plates wear and tear. So far, been using Shell Ultra.. so far so GOOD!! Better performance and I guess, if we chiong, any EO also cannot protect us from wear and tear!

[iCeLkipS]

But of cos, dont be funny and use COOKING oil instead!

[mamu27]

do a quick google.

there are reasons why 4T oil meant car isnt suitable for bikes.

unless ur bike using dry clutch. then no worry.

but still, the nature of bike's high rpm engine isnt so suitable for car's oil where their engine are max out at 7K rpm?

 

another note, most car 4T oil contain energy conserving addictives. these will make ur bike's wet clutch to slip. and even if u've only used the oil once, these addictives will still be on ur clutch/fiber plates, so the best and only solution is change the fiber and clutch plates.

 

so pls use suitable oil for ur bike or car respectively.

these engine oil are already specifically formulated for the different types of engine.

[mepkoh]

can i add on something oso? Can car engine oil FILTER be used on bikes? I got a suzuki car filter that is cheaper than suzuki bike filters...

.

 

hey you guys...try not touse stuff meant for cars...unless you are absolutely sure..

 

for filters..there are many out there...the filtration capability (size of particals,vol per min, pressure..etc...

 

some filters comes with presure release valves..some mnay not have it..

the beat is check with your bike distributor...for me i wont..there is too much variable to consider..
