I'm afraid what you are saying is not correct in this context

To put it very simply, only API group IV and group V basestocks are considered true synthetics, technically. Legally, even group III and up, is synthetic.

Group IV and V are polyalphaolefins and esters. Hence ester based oils are considered true synthetics of the highest grade.

However, given the data you have given, Petronas 5000 with its PIB and ester base seems to be a true synthetic, technically.

I think the Motul 800 s overkill. We don't have 2T bikes here that really require it. Besides, its just too expensive. The Petronas should be good enough.

If only Motul got the 710 here. It would be ideal.

**Raccoon** · 09-05-2009, 07:14 PM

710 will again be too expensive. My guess the price will be near about the 800's price. Thats why 510 is a more realistic option, and is now available.

I dunno how you say that 800 is overkill in our bikes? With my RD revving to 8500 easy and stock RX doing 9500 in every gear, and ported RX doing 11k. I don't bother with anything other than motul.

Also FYI, 2t oil does not only lubricate the block/piston combination. But is the ONLY source of lubrication to your crank main bearings, big end bearings, and top end bearings.

You can avoid seizure by running a lil rich/backing off the timing etc, but you cannot avoid a screwed up top/bottom end bearing or main bearings except by running good oil.

Varies from person to person, but I love my bikes too much take chances with their engines.

I'd agree with that. Good lubing and clean burn can never be an overkill... esp. when you have a bike whose parts aren't easily available. The only problem is 800 is just too expensive. Other issue (for auto lube users) is that its supposed to be used only as a pre-mix.

So are you saying that the 710 or the Sprinta 5000 just aren't good enough to protect your bikes engines?

Are you using the oil sump/pump/tank?

Why is it so? I was thinking of switching over to Motul, but if it cant be used in the pump might as well stick to Yamalube I guess

Perhaps because its thicker and/or is immiscible in gasoline. You can use Motul 520 I mentioned eariler with the pump. Definitely better than Yamahalube. Motul 800 is ment to be used as pre mix only.

Was that a typo? There is a 510, is there a 520 too?

Guys, I have a ported RX 135 5Speed running on 58mm pistons and asome other mods. Right now, i disconnected my 2T oil side box and fill the oil directly into the tank along with the fuel (Engine got seized thanks to that stupid pipe getting clogged). Right now, am using ONLY shell super-premium (or something of that sort) petrol with 5% oil. Is this safe for my bike?

Oops... sorry! That was a typo. I meant 510.

Do you mean Shell VSX2? Amongst the Indian makes, its supposed to be amongst the better oils. The imported (French) Motul 510 is much better...

Btw, 5% oil seems to be too much. Generally more than 3% is not required at the very max. You have to take care to keep the pipes and all totally clean... the passages are very narrow! How did it get clogged btw?

I have no clue which oil it is. That is why I was asking. This is what is pre mixed in the pump. i tell the guy to set it to 5% and pour in how much ever fuel I require. I have no idea how it got clogged. Was ridding happily one day and the bike seized up. The pipe stopped giving oil and later it began to on its own again.

hi all,
my shogun has just been through a complete engine rebuild and am looking forward to breaking her in . . .
wanted to know if its advisable to use synthetic oils at this stage . . .
(any other tips for running in would be greatly appreciated, its my first time running in a two stroke you see . . .

)

i guess mineral based oil is the oil you normally get at the pumps?
i've read somewhere that you're not supposed to use synthetic for the run in. Please advice
