engine oil eh

[B20]

guys... need some help from u...

heard bike n car can share engine oil... isit true?????

meaning bike can actually use car engine oil n car can also use motor engine oil...

learn this from a car mechanic... n was recommended by him... but still i doubt... so need 2 hear from u guys too...

[MonoWorld]

dun use car's eo on bike. it will cause clutch slip.

[stsoh]

if u want to use motor(car) oil make sure it have API grading 'SG' / 'SH' or JASO 'MA'.

 

latest API std is 'SM', the latest is not always the best for your bike.

 

motorcycle manufacturers recommend API standard 'SG' or 'SH'.

 

reason is after API 'SH', oil manufacturers replace wear additives (ZDDP) with anti-friction modifiers due to enviromental issues.

 

BMW motorcycle will void warranty if found consumers using oil with API above 'SH' grade.

 

API = American Petroleum Instititue.

JASO = Japanese Automotive Standards Organization.

Very true.. To TS, e grading is e upmost important factor.. Use e wrong one and u'll end up paying more for e repairs.. Guess best solution is to stick with Bike Engine Oils??

[stsoh]

some motorcycle engine oils have API 'SJ', 'SL' gradings.

seen motorcycle TOTAL brand at carrefour with API 'SJ'.

just watch out for it.

look at the labels n search for API 'SG', 'SH' grades or JASO 'MA'.

Brothers, I got one question.

 

I know that there are EO made specially for cars and bikes. I also know bikes risk clutch slip (wet clutch systems) if car's EO is used. But is that the only problem? If it is, is it alright then for a bike with dry clutch to use a car's EO? I mean, what are the other potential problems that may arise?

 

I think that makes 3 questions...

yes, anti-fiction modifier agent can coz clutch to slip if your bike produce more torque to cause it.

 

 

if car's EO is used. But is that the only problem? If it is, is it alright then for a bike with dry clutch to use a car's EO?

yes, u can use car's EO if your bike employ a dry clutch n cruise at the same engine revolution as car engine do.

most car cruise at 3~5,000 rpm, most bike cruise at 6~8,000 rpm.

 

 

I mean, what are the other potential problems that may arise?

 

I think that makes 3 questions...

motorcycle engines r more stressful than car engines.

bike revolve as high as 14,000 rpm compare to car at 8,000 rpm, thus higher stress n shear pressures.

due to lack of anti-wear additives (ZDDP), can expect higher wear of engine components.

seriously.. i tink sumtimes we may be thinking too much..

 

i m using Mobil Delvac MX 10W-40 on my bike.. and it has ran fine with no clutch nor engine issues.. Delvac MX is a semi-syn EO designed for use in commercial diesel fleet but has gradings to use in gasoline engine too..

 

if u search online.. u will be able to find reports that MODERN car oils.. can take the abuse of motorcycle engine and the rate they lose their viscosity is about there of a motorcycle EO.

 

btw i m riding a WAVE now.. n i have ever tried it as crankcase oil for my 2stroke NSR last time.. both are wet clutch too..

 

n juz for info.. i use it juz bcoz my dad brought some home which was the remainder of what was used in lorry in the workplace..

Thanks for your input guys. We learn something new everyday!

honda cub 70 can run even using cooking oil.

 

but what is the usual engine oil temperature of your honda wave?

max RPM ???

 

i believe it's much cooler than most other bikes out there. especially class 2 bikes.

yup precisely why i haven mentioned for the class2s to try these kind of weird gimmick.. if u got the cash for a class2.. dun scrimp on things liddat..

 

oh juz for info.. diesel engine oil are very temperature resistant.. huge turbo diesel engines definitely churn out alot more heat than any other vehicle on the road...

[stsoh]

different viscosity index betwn diesel engine oil n motorcycle engine oil.

low vs high revolution engines,

low oil flow vs high flow,

high pressure vs low pressure,

high temp vs low temp,

loose tolerances vs tight tolerances.

beware of wat u want n use for engine type.

too thick viscosity may be more damaging to engine.

oil may not flow quick enough to lubricate critical components.

tight tolerances may be too restrictive.

loose tolerances may not be able to retain pressure.

[Pplater]

API 'SG', 'SH', 'SL' grades or JASO 'MA', what is the order of good/expensive oil

and which is the minimum for a motorcycle, class2A/2?

 

will read the links by stsoh another time when free

[stsoh]

there is no orders which is better or worse in ranking.

motorcycle manufacturers recommend either API 'SG' OR 'SH'.

JASO 'MA' is another standard specification for 4-strokers motorcycle.

avoid gradings API 'SJ', 'SL', 'SM' or the latest unless it is specified by motorcycle manufacturers.

 

100% full synthetic oil is the best after break-in/run-in period for new bikes, good for any old bikes.

avoid those labelled 100% synthetic using hydrocracking process, they r only higher class than semi-syn oil, it's not truly fully synthetic.

 

based on our climate (ambient temp 26~33 deg C):

water-cool bike recommend oil grade: 5w-40, 10w-40, any SAE 40 grade.

air-cool bike recommend oil grade: 15w-50, 20w-50, any SAE 50 grade.

hmm.. dats definitely true.. haha.. i m juz being a cheapskate coz the oil is free~! haha.. :P

 

but definitely if i tink if we were to buy the oil.. get the MC oils.. i would too if i m paying for it..

bro... really thankz alot for all ur info...

very sad... i rode for so many years n change countless of engine oil liao... i dun even know wad is all these n the diff...

 

btw i would like 2 know how do we actually determine which is the best grade for our engine????

like choices between fully n semi... SG or SH or MA...

and wad is acturally the diff of 5w-40 and 20w-50???? wads is 5w and wad is 20????

seen motorcycle TOTAL brand at carrefour with API 'SJ'.

For SJ', 'SL' gradings, u mean tat they re meant for cars only?

which is the best u r asking?

i'm not sure but i use Royal Purple Max-cycle motorcycle oil.

it all depends on the additives added by oil manufacturers.

do your research, some motor mags have done experiments showing which oil manufacturers have the right amount additive mixtures to protect your engine.

for example, this car mag article for motor oil:

http://www.animegame.com/cars/Oil%20Tests.pdf

 

read this, all you need to know about oil:

[stsoh]

For SJ', 'SL' gradings, u mean tat they re meant for cars only?

yes, API 'SM', 'SL', 'SJ' r for cars use n not recommended for bikes.

API have obsolete 'SH' n grades below it, due to ZDDP can cause damage to catalyst converter in cars.

motorcycle manufacturers still recommends API SG or SH grades, pls read your bikes' manual.

JASO certified Oil

 

Another institute that certifies oils is called the Japanese Automotive Standards Organization, JASO. One wonders why this Japanese organization has an English name. . . In any case, they have two classifications for motorcycles, "MA" and "MB." MA is the one you want. MB is like the API SL category, it's got all those nasty friction reducing chemicals that may scare your clutch into misbehaving. Again, there is an official JASO seal if the oil has been independently tested. The seal is a rectangle; in the upper quarter of the rectangle will be a serial number, and the lower three quarters will just have the letters MA. If the oil manufacturer did their own testing, instead you'll see just words like "Meets or exceeds JASO MA standards."

 

Some manufacturers recommend JASO-MA certified oil. AMSOil and Golden Spectro are JASO-MA certified. Some people consider this important. Interestingly, although Honda recommends a JASO-MA oil, Honda oil is not JASO-MA certified. Mostly JASO-MA is pretty much equivalent to SH. In fact, the JASO spec is mostly a reaction to the decrease in zinc-phosphates in SJ and SL oils, and the added molybdenum disulphide in energy conserving oils. Personally, I don't care about JASO standards - they're really not on my radar. - taken off from a website

By the way, my frd told me Total is certified as API SL.

[299]

But found in the Total website http://www.lubricants.total.com/lub/lubroot.nsf/VS_OPM/51BD2028B3C10BECC1256EF300500376?OpenDocument

 

The total brands we are getting here in SG are quite different as compared to the overseas ones.

[Hydher]

Taken for a webbie is.

 

API gives ratings such as SA, SB, SM, SL, and CF. “S” means the oil is for spark-ignition engines, while “C” means it is for diesel engines that use compression to combust fuel. The second letters, on the other hand, indicate which engine models the lubricants are compatible with. An API SL rated oil, for example, can be used for 2004 and older engines, while an SA rated lubricant can’t be used in engines built later than 1963. SA up to SH ratings are now considered obsolete and should not be used in modern engines.

 

Taken from my manual is

 

Engine Oil

Good engine oil has many desirable qualities. Use only high detergent, quality motor oil certified on the container to meet or exceed requirements for API Service Classification SE, SF or SG. It is not necessary to use additives.
