though motomix has a flash point of 100'c i've heard motul 510 is better!! have'nt tested either!! that's why i said with only flash point the oil's quality cant be decided!!

Motomix has it's flashpoint at 100c whereas 510 does a 92c

brother!! mineral oils have less flash point than synthetic or other oils! so it naturally behaves a bit bad when compared to synthetic!!and also depending on the flash point alone you can't judge the quality or behavior of oil!! Flash point can be increased by adding certain additives to oils(which many companies have done) !! but that would hamper its performance in some other area. so yea if the flash point is high then thats a good oil provided it has a good rating in JASO or ISO(C or above) !! i have heard that Flash point above 150' C is a good bet for mineral based oils.dunno abt the value of yamalube or motul!!

Bet your googling didn't reveal how mineral oil behaves at flash ploint lol and please try to fathom the question properly I didn't ask for the flash point test I just wanted to know how can one judge the goodness of 2t oil from the flash point value given the DS.

Flash point is the minimum temperature(of the oil) in which the vapor of the oil can be ignited!!the ignition is considered from a different source and not auto ignition!! you can find the easy answers by googling as all here do!! but still if you really want to know the concept of flash point and fire point > you can find it by doing a diesel heating test!
1.heat diesel(very few quantity) in a metal vessel (or some bowl,i don know to name it )
2.after certain time, you can find some vapor coming from diesel negligibly!
3.now try igniting the vapor ( not the diesel liquid directly) it with normal match stick!!
4.at certain point you can find a spark or a flash of fire due to burning of vapors!! this flash instantly goes off!! it will not hold !! this is FLASH point!!!
5.if you further heat it and try to ignite the vapor you can find at certain point the vapors getting burned and i wont stop even the match stick goes off!! this is fire point !!
I asked to do this test on diesel because you cant really heat the engine oil to it flash temperature since it will take long time and requires strong heat source!! also diesel has a very good flash and fire point difference !! so you can learn it easily!!
P.S> be cautious!! again take little of diesel and not more than 100ml max!!

Normally in engines heat is highly developed by friction of gears and the oil is the one which helps in dissipating heat and lubricating gears!!if low flash point oils is used it will/tend to burn in some temperature which leads to improper lubrication and heat dissipation!! now since high flash point oil's dont get ignited easily they are better in performance!!hope you understood the concept!!

Guys can anybody comment on how the flash point contributes to the goodness of a 2 stroke engine oil? I have gone through so many threads and everybody raves about how a high flash point oil is better than a low flash point oil but nobody corroborates this claim. Can anybody shed some light?

Go for MOTUL 510 2T, its the best!

Ok. I live in Mumbai so getting Shell is tough and for Motul I have to go hunting everytime I need it.

Which is the best 2T oil among our petrol bunks??

We have Shell, Yamalube, Motul to name few.

Shell and Motul have good reviews, Off course, Yamalube which is recommended for Yamaha bikes performs too. Choice is yours.

To run Semi-synth or fully synthetic, go for Motul for results.

Ok.I have done as you said.

So what all option do we have for our bikes.

Could you please post your introduction on 'Who are you' thread of this forum?

Personally I have not used HP Racer for my RX.

Has anyone have any thing to share on HP Racer 2 ???
I am thinking of using it, so can anyone share their experience...

Then I will stick to my humble Yamalube 20W40, cheap & besht

Franklly speaking havent noticed any difference, the smoothness was same with a 20w50 oil and 15w50 double ester. make sure you dont go below w30 grade thats all ..

Yeah, but would the gear shift quality improve? Would gearshifts become smoother?
