Thanks to the 4 who replied to my question/musings yesterday 
<br /> My main wondering was what happens if you use less or more 2-stroke outboard-engine oil in the gasoline - I was just curious, but now get the general idea just to use 1:50 as Evinrude tells.... this is a 20hp 2-stroke from 1997.<br /><br /> Here's with the fuel: yesterday I drove from Sipoo to Helsinki again but deliberately slowly, it took 1hr50mins as opposed to about 1hr15mins last Saturday; then this trip had taken 11 litres of fuel. Yesterday it took 11.5. I do realize the longer an engine runs the more fuel it will use anyway (simply because of the time/engine having to tick over - 'idle'), but I had hoped a slow steady drive would show some fuel-saving (I drive buses for Helsinki City Transport and have been on fuel-saving courses)......<br /> .....I re-measured the distance and it's about 25km, not 20 as I had originally estimated. This means that 'Xcuseme' (why? what have you done??!!) and 'phatmanmike' are correct in saying it should use 7.5 litres/hour - that's 44 litres per 100km.<br /> So, now I have a very good idea what the situation is/should be, and can estimate distances & fuel needed for future trips (and to start arranging a loan at the bank in order to buy some fuel!!!).<br /> I do know about saving fuel by not having the engine "full-throttle", but I can't see otherwise how to save fuel - the sea is bumpy and that's that By the way, this boat is an American "Galaxy" (spelt right?) fibre-glass from the 1970s, just an open boat 4.9m long - not a luxury yacht but I reckon we can have more fun with this, we can cross shallow water (and if it's very shallow, engine up and use the oars!). A slight disadvantage is that there's not much room for glamourous girls to lounge about drinking cocktails in their bikinis...<br /><br /> So, thanks for your replies. Isn't is funny that you can put up a question here and straight away get 3 answers from the USA & 1 from Denmark! If anyone's thinking of a trip to Finland, maybe I can give some advice?! (yes, use more oil, we have mosquitoes!!!)<br /><br /> Ross T.
