You're right, I got confused until I get that Shell stuff & was mixing. Thanks for the pointer. I think the only fully synthetic oils now are Petronas or Motul, what do you think? Could you guide me pls?

Regarding transmission oil, yes, you're right; I wish to stick to the best option rather than the manufacturer's recommendation.

Believe it or not, Mak also had a full synthetic Bio 2T oil. Will check with them if its still available.

Go with the Motul 5100 15W-50 in the gearbox. You'll love it.

Ok, I'll go for it, but not now, will do it once the motorcycle is rebuilt. Correct me if I'm wrong, is this the one that we use on to the right side of the motorcycle right? And this is not the one we use on the oil tank right? Motorcycle I mean is RX135.

Yes, in the gearbox on the right.

@Straight6 - One more question to you. Are there any fully synthetic 2T oils? Even Shell, I guess is synthetic based & not fully synthetic. Are these Motul 800 stuffs fully synthetic oil? And is that the reason they cost more?

Motul 800 and Petronas Sprinta 5000 are full synthetic with esters.

Sorry, don't get much time to log in here lately. On what would you like guidance? Anyway, I guess Straight6 has answered most of your questions. As for the gearbox oil, while the imported Motul fully synth is great, its very pricy and may not really be worth it just for the gearbox. If you don't want to spend so much, Gulf, Elf, Valvoline are the best options. You get Indian Motul 20W40 also, but its not as good as the above mentioned oils and has shorter life.

Have seen that somewhere. IIRC that is for marine use only. Don't think its recommended for bikes.

I thought Motul 800 was kind of 2T oil & its too much priced for everyday usage. But if its the same for gearbox oil, then I don't mind as the change interval is increased. Correct me if I'm wrong.

You're more than right on motorcycle's recommendation. Actually, somewhere someone tried Motul & found that the metal wear & tear is getting less with this oil compared to all other oil & started recommending this. Though I haven't personally seen, I heard people saying that there's no such sentence called "Motorcycle 2T oil" on Motul cover.

straight6 · 8th April 2010, 09:47

The Motul 800 is meant for the engine and not the gearbox. The Motul 5100 is semi synthetic and can be used in the gearbox.

aargee · 8th April 2010, 09:51

This is totally confusing to me

; Guess I need to go through this thread completely.

Yes Motul 800 is 2t oil. 5100 can be used for gearbox. But don't believe it will last any longer than oils like Gulf, Elf, etc. Gulf and Elf are rated for about 5,000 - 6,000 km in 4 strokes, depending on usage pattern. So they should easily last the same period or in fact longer in 2 strokers (depending on usage). Don't know about Valvoline.

I'm etching ^^^ into my heart; Thanks for saving my time.

straight6 · 8th April 2010, 15:45

The 5100 will last much longer as its semi synthetic. Besides, the oil lasts much longer in gearboxes than in the engines.

Raccoon · 8th April 2010, 16:05

^^^Don't be too sure of that! The oil will shear and loose viscosity, etc., even in a 2 stroker. Besides there is a time limit to how long you can keep it in the gearbox, regardless of use.

However, my Shogun manual mentions that it can be used upto 6,000 km. And this was when oil grades were far lower. So maybe extended drain oils like Gulf, etc., may last longer... but its not a risk worth taking, IMHO. Besides for me, I come nowhere even close to 6,000 km in a year. I change it annually. Not a good idea to keep it longer than that... even if usage is low.

straight6 · 8th April 2010, 21:50

The 5100 or any full synthetic oil will easily take 6000 kms in the gearbox. For me that is 5 months of riding.

I generally change the oil if I find that the gears are not shifting smoothly on long rides or in traffic when the bike is warmed up.
