Are all 2 stroke oils the same?

[cornishman07]

Obviously they're not and this isn't a what's best or brand X Vs brand Y question but can chainsaw 2 stroke be used in a MX bike and vise versa or are there specific oils for specific applications? I've always used the green Stihl synthetic in the chainsaw/cut off saw etc @ 50/1 and Castrol or Motul 2t in my dirt bike @ 60/1 both mixed with super unleaded but I am thinking I'll just use the green Stihl @ 50/1 in all logic being chainsaws rev higher so should be fine in lower revving bike? I know it's not a big deal but it would be easier if I just had one lot of fuel to use!

I believe I've seen people on ope forum in the us using the Motul 2T in saws, they might be slightly different to saw oils but can't see them being a million miles apart. Stubby uses Red Line Racing 2T in saws.

Just bung it in and ride it/cut with it like it’s stolen, is a basic 2 stroke motor in either machine not a space ship!

 

Decent quality oil is decent quality oil. Decent oil vrs cheap crap I would say spend on good quality and the machine will last longer but apart from that I stand by my first paragraph!

 Oi oi then Mark . I think there are differing quality 2T oils . This can be determined by the ratings but what they mean you would need someone like old TCD to tell you . What I do klnow is you should not use marine 2T oil in anything other than an out board motor . Again I can't remember why other than its a temperature thing .

Cheers for the replies guys!

We sell a lot of Stihl (50:1) 2 stroke oil to owners of these little chinese pit bikes, and RC planes and cars without any issues.

 

As previously mentioned, never use marine 2-stroke oil though.....and never buy generic unbranded 2-stroke oil from places like screwfix, b and q and garden centres that give no specific dilution ratio ON THE BOTTLE. If it states 'consult operators manual' on the bottle...bin it. Its is the manufacturer of the oil...not the machine that knows the recommened and correct ratio for THIER oil.

 

Stihl green is good, and popular. Low smoke and low carbon build up. Was specifically manufacturer for the Stihl 4-mix low revving engines....if you run one of those, then thats the oil you must use. Seen too many carboned plugs, exhaust ports and pistons on those that havent used it.

Stihl Super or Ultra? They're both green but Ultra is supposedly better.

I went through 5L of the Super and it lubes alright but smells bad and is rather smoky.

If you can afford it Just use Red Line Racing 2T oil . Its the best you can get ( IMHO ) . I use it mixed with an alkylate fuel at 50:1 .

Slim chance of that, someone posted a photo of a trainee leaving a slightly high stump a few years ago and he fully shit the bed and left 🤣
