Two-stroke oil consumption

[Badjelly]

Though I don't have two-stroke motorbike, in the last week I've enjoyed an intimate relationship with a piece of horticultural machinery that uses a two-stroke motor and I've been wondering about something...

I use Castrol TTS and at $27 per litre and 50:1 premix, this means that for every litre of petrol ($2.00 and counting) I spend $0.54 on oil, which is quite a bit really. Now I understand all two-stroke bikes and scooters these days have a separate oil tank and a pump to meter the oil. What sort of oil consumption do these give? Either per kilometre travelled or per litre of petrol consumed?

My KRR ran at about 1:35

I had a 50cc 2T scooter that mixed it's own, about 1l oil per 1000km. In that 1000km it would use 30l petrol, so 30:1 fuel/oil

my 50cc gasgas uses about 1ltr per 2000km, so i guess that's 0.5ml/km.

You are paying too much for your oil !

Have a look at TOTAL oil. Fully synthetic $17l.

Still no more expensive than a 4-stroke. It will need oil, filter, valve clearances.. you just need oil.

Personally, for my specific application, I use TTS because that's what the manufacturer supplied, it's a very expensive piece of kit and the cost of downtime greatly exceeds the extra cost of a premium oil. But if I were running a two-stroke bike/scooter, I'd be looking at alternatives. Thanks for the suggestion.
