Hi all,

In my recently acquired GT380 is a gold coloured oil in the CCI tank. My local restorer suggests it's probably just normal engine oil POs have been using instead of 2T oil (he says nearly all 2T oils are red??)

The suggestion is to run the oil really low then top up with a proper 2T oil.

If (If) it is normal engine oil then the chances are that it's at least a semi synthetic. If I then top up with a semi 2T oil all should be good - right??

I'm not good enough with this engine yet to want to drain the system and re-prime.

Does anyone use ordinary engine oil as a 2T?

Hoping this doesn't come across as a dumb question but my last 2T engine was 46 years ago and that was pre-mix.

BTW - the more I get to know the 380 the more I like it - reminds me of my youth - when I had no money to buy one.

All the best

David

Hello David,

2-st oils come in a variety of colours. The Castrol A747 I use for racing is gold in colour for instance. The colour is just a dye added to the mix and I have seen oils in Red/Purple/Green/Gold colours. I would not run a 4-st oil as the engine oil in a 2-st if I could help. It should be relatively easy to drain the oil tank at the tank end, leaving the lines undisturbed. You will only then have to empty the lines and not the whole tank.

Cheers Geoff

Thanks Geoff

I have a vacuum brake bleeder pump that I might use down the filler of the tank, pump out as much oil as I can and then top up with 2T oil, run the bike until I can see the new oil in the pipes and all should be good. (I hope!)

IMHO i would drain the tank and flush the oil feed pipes too. https://youtu.be/necW4LnXBHM
You have no idea what is contained in the oil tank it could be contaminated with anything. Just a heads up you cant mix mineral oil with synthetic as this causes the oil to 'gloop' which is similar to clotting. This is just my opinion its your bike and your choice.

Hhhmmm.? The PO was well into his 2 strokes but he didn't ride the bike much and only had it a few weeks so probably didn't put an oil in
.

The PO to him had it 5 years......(brain wave) I have his details so I might well ask. The stuff in there could well be pukka.


Don't you just love bikes? Thanks for the link.

+1 - Drain and change.
Why risk it, your whole engine is at stake just for the sake of a few bucks for fresh 2T oil.

When I was at the young and stupid age of 16 I seized a 2-stroke while running on 4-stroke oil. Its not worth the risk, especially when an engine rebuild costs so much on a triple.

I agree lads. I'll purge it and be done with it. Thanks

A wise decision. Losing a few bucks worth of oil is a lot cheaper than an engine rebuild.

To be fair I don't think either of the previous POs would skimp on oil but, hey-ho, not worth the small risk.

Is it easy to remove the oil pump without taking things like the carbs off too? It looks a bit congested around that area.

Thanks

Panic over I hope.

I managed to speak to the owner before last (last one only had it 3 weeks) who is a very nice guy and really helpful - and reassuring about the bike itself.

Oil is Silkolene Scoot 2 Semi-synthetic so I'll carry on with that for a while.

Thanks for all the posts lads, I really appreciate them.

David

Great news save you some time but just one more bit of advice. Your local restorer who told you "The suggestion is to run the oil really low top up with a proper 2T oil" hasnt a clue about 2 strokes!

Thanks GT - future words of advice from him will be taken with a pinch of salt!

So if two 2T oils are both JASO FC / API TC, are they basically the same and equally competent? Both semi synthetic 2T oils.

The Scoot2 is described as for scooters, mopeds and minibike engines. Any good for a GT380 engine?

Sorry about the questions - I'll get there eventually !!

Thanks
