I'm am using Castrol TT at prescent, and have about a 1/4 left in the tank. I've just bought some anti smoke 2 stroke oil. Can I just put it straight in with the remaning TT oil?

most semi synfictics are ok to mix but never mix fully sysenftic (TTS, A747, R2) with others seems to gung-up

The only ones that REALLY don't mix are vegetable based oils and mineral ones. You would know if you have a vegetable based one because you would have to have gone and sourced it from a specialist supplier.

To be certain, try mixing a little of both in a seperate container, if it goes lumpy or milky in colour, don't mix them.

I wouldn't call it nasty, some good brands have low smoke semi-synth. All depends really what bike it's for.

the pikey bastard that owned my KR1-S before me ran it on low smoke semi-synth which is ok for peds and 125`s, but not performace 250,s which is proberly why it seized 1 week after l brought it.

only castrol R2 for me (£13 per lilter)

cos my scooter has a MHR rep engine, i like to look after it. Razz

so i put shell Optimax in it. and i also use either Silkoline scoot sport 2T, or Castrol TT racing 2T!

Mixing oils isnt the best thing to dom but aslong as they are similar oils it shouldnt matter too much as it is all geting burnt isnt it?

but id advise ppl to try to stick to the same oil throughout the lifetime of the scooter. and Fully synthetic is the best!

Of course the best is the castor oil based Castrol R.

You can't use it if your bike has been run on mineral oil...but the SMELL is fantastic (ever been to the classic racing or speedway?). I know quite a few people who put a little bit in their petrol tank just so you can get a whiff of the stuff Mr. Green

i kno,

that sucks. when i first got my first speedfight which was a X race (brand new) i ran it on Castrol R for a bit cos it smelt fantastic. but i couldnt afford it, so i changed to synthetic Casrtol 2T. but then its like a 1 way thing u can go from Castrol R to mineral oil. but u cant go back... why is that?????!

Because castrol R turns into jelly when it hits the mineral oil that is sitting about in your crankcases and bearings and would gum up the whole engine.
