Oil Types - Pros and Cons

[Zim_Invader]

girlfrien asks how i come to know the very wierd/random things about bikes that i do. my answer.. rob norris! (she never gets it... then again, saying i steal the knowledge from kb is too easy an answer anyway... pronouncing motorbycyclist is too much effort, and saying squiggs lots of times, over and over again leaves the tongue numb. hahaha... i love bikeS! threads like this are awesome for ppl like me. just don't know, and know even less where to start! cheers timati. u started a good leaner-aid thread!

Jesus H. Christ on a stick Zim. I feel like finding a handy brick wall to beat my head against after every one of your posts.

needs MOAR complete sentences!

(isn't too bad anymore actually, just needs MOAR spacing too)

there is Only one brand of oil, the rest are pretenders

Mobil 1 Racing 4t, fully synthetic race oil (as I use)
Mobil Extra 4t, semi synthetic

Available from

MOBIL

The more expensive oils Valvoline etc provide better lubrication at higher temps

So are you suggesting the more expensive they are, the better lubrication they provide (doesn't sound quite right, haha, wonder if they say the same thing for condoms)

Valves? Oil change? we're talking two smokers, where the only oils the stuff ya burn and the stuff that keeps the gearbox nice

I liked the repsol stuff, never switched off it, burnt cleanly and rarely gunked up, had that lurvly smell too

Cool. So did you use the others and see a difference?

Gotta be careful with additives as they're usually designed to decrease friction.
As most motorcycle share oil between the engine and clutch using additives that decrease the friction could cause the clutch to slip. Also the shearing forces exerted on the oil in the clutch will degrade the polymers quicker, hence the shorter oil change periods than cars.

And to actually answer the original question, any two stroke oil from a reputable motorcycle show will do you well (as long as it's suited to your bike) no reason why or why not as most of them are effectively the same, motul, castrol, all the same shit.

and all this while drunk, sweet.

How do you know which is well suited for your bike if the manual doesn't outline it? For example, I noticed a difference in performance when I used the fully synthetic oil from Mobil in comparison to Motul. Does it mean it's better? If so, why?

Solve the problem get a 4 stroke hahaha no more angry grasshoppers stuck in your engine....

I used to ride a NSR250 lotsa fun until you get blitzed by a GSXR or a Duke...

Nah, love my RS too much to get a 4 stroke.

Haha, I guess a conversation about lubrication always helps when with the ladies..

Apart from the apparent drool, haha, why is it better? Don't want to know the intricacies of it but would like to know why one outperforms the other and how do I know which one to use?

I would say there isn't really any appreciable difference between brands of oil (and I may well get shot for spouting such blasphemy)

But the difference between fully synthetic and not synthetic (word escapes me presently) is that the fully synthetic is engineered so that all the molecules are the same length and have the same composition, thus providing better lubrication and lasting longer while the non synthetic oils are made naturally and contain imperfections.

thats a fairly good summary, yes the Synthetic oil is refined from Ethanol > Polyalphaolefins the advantage is as suggested above is the molecules are all the same size and shape, this enables a easy glide between metals meaning less friction, think of it like the same size ball bearings between to steel plates vs multi sized ball bearings between two metal surfaces, Synthetics are better at keeping the metals apart and obviously one is going to glide better than the other.
Less friction = less heat = longer engine life and increased fuel efficency.
Also the oil life is better as well, its a win win.

Synthetics are the way to go.

There are some differences between companies oils, for example Castrol say its synthetic but it isnt a trus synthetic its a highly refined Mineral oil with lots of additives, Mobil took them to court over this but they won the right to use the word synthetic, even though its not a true synthetic as has been developed, so be aware that there are some inferior oils out there. Mobil is the leader in synthetic oils and legally Im allowed to say that as its a fact.
But taking the Mobil Hat off, there are heaps of good oils out there but there is only 1 top one

Found 2 good sources which delve further into what oil is -

Enjoy the attached 'Engine oil bible'.

Found somewhere on KB I think, but cant find it again - so it's a repost I fear.

Zim can read my 'How to write stuff good' practice papers (if he's bored or forced into it by the junior Hitchers here)

[AllanB]

Sometimes a little bit of friction is soooo good. Ahhhhhh


As can be a little lubrication. Ahhhh


If you know what I mean eh??



Wink Wink nudge nudge



Say no more



You did not see me alright ...................

^^^ Thank you MB for an updated version (and a good rant to read)

[klyong82]

I have only been using Motul on the last 5 of my bikes.....I'll been keen to try out Repsol or Mobil next oil change......heard wonderful things about the Repsol and Mobil...reduces the clunky sound from a Honda transmission...

i find that the best oil is found on the face of teenaged virgins that work at takeaway joints
