What two stroke oil are you using

Hi as the tile says just asking on opinions on oil recommendations . I run a Tohatsu 70 c and always use Quicksilver Premium Plus .It would be nice to use something of the same quality but with a nice smell of the old Castrol R or similar

Any tcw3 is fine but apparently most good quality motorcycle oils are far superior to tcw3 which isnt a particularly good spec of oil. It costs manufacturers to display the tcw3 rateing so many oils which far exceed the standard dont carry the designation as it a relatively small market

Interesting thanks always thought it had to be TCW 3

The trouble is there will be two stroke oils for air cooled engines which run far far hotter. While some oils will be fine for both, without TCW3 badge you are left to guess...

Same boat and engine. Stick with Quicksilver. The Tohatsu is an agricultural lump, but it’s built like a **** brick house and the autolube has worked faultlessly. If it ain’t broke would be my approach.

There was an oil company guy posting on here for a while & he explained the whole tcw3 thing was brought out as a minimum standard for parts of the world where oil & fuel quality is pretty low. He reckoned most good bike oils would be far superior to tcw3 which is relatively low grade. The down side is bike racing oils etc are more expensive anyway so rather pointless. Tcw3 is cheap enough to buy so personally I stick with that but don't go for any particular brand. I don't like paying for expensive lables

In the last few years I have been buying exol marine 2 s tcw3 and it comes in a 20ltr drum for 89£,

Certainly good value and does the job for a yam 115 and a mercury 60.

Easily found on the internet.

I was told years ago by somebody I trusted that Outboard and Motorcycle 2T Oils are formulated differently and should not be used in place of each other.
I've never checked or investigated the claim but it makes sense on 2 counts.

Bike engines, especially Air-cooled ones, generally run hotter than outboards.

Outboards tend to be run at constant speeds for longer periods of time at mostly higher revs, whereas that's unusual on a bike unless on a long motorway trip.

Think you took the advice the wrong way, its the tcw3 thats the lower standard, good bike engine oil is designed to protect over a greater temperature range from cold starts to roasting hot in air cooled & liquid cooled engines sometimes running at 15000rpm. Tcw3 on the other hand only has to work at moderate temperatures due to cooler running & far lower operating rpm of 5000rpm ish, continuous load is less harmful to an engine than constant throttle & load variations. I wouldn't use tcw3 in my stihl chain saws or motorcross bike but in a pinch I might do the reverse.
Its realy a hypothetical argument anyway due to tcw3 being far cheaper than a good brand bike oil so no reason not to use it unlessyour stuck. I wouldnt use the cheap 2 stroke oil you can buy in the likes of screwfix in anything I actually cared for though.
