April 10, 201214 yr Following on from a comment in a thread in the Beta section, and out of my own curiosity, what is the best technique for mixing 2 stroke accurately?
April 10, 201214 yr ..''Shaken not stirred'' of course Get your lady's measuring jug from 't kitchen and a 5litre petrol can (plastic?) and experiment to your hearts content. All of my trials bikes have been mixed at a ratio of:- 70mL synthetic pre-mix oil to 5L of petrol ....and I've never had any problems in 10 years
April 10, 201214 yr Get a syringe marked to 100ml. Use a soldering iron to remark the graduations as they will dissolve off in a short while. Attach a piece of hose to the end of the syringe so you can dip it into a bottle of oil and suck up measured quantities of your chosen premix oil. Some people measure out petrol in jugs and decant them into a can to get spot on accuracy as fuel station meters arnt always correct but I find this quite a laborious and time consuming process, I prefer to just fill up either a 5 or 10 liter can, add oil to it then get the missus who ive appointed chief petrol shaker / mixer to do her thing while I stand back and whatch her bouncy bits jiggle while she does her thing for a few minutes. Any excess left over goes into my car or saved for another day. Keep the syringe handy for other tasks like filling the gear box oil, bleeding brakes etc.

April 10, 201214 yr I use a small measuring jug and put 80mls into a 5 litre can, give it a shake and pour it in the bike. However, the girl in this video mixes her's a different way. :popcorn:
April 10, 201214 yr We won't ask how you discovered that web site Pete ....while I'm here; Fill container with fuel, fill measury jug with oily stuff to desired level, add some fuel from aforementioned container, give a swirl about to mix oil with fuel, pour back into container, do the same again to catch residual oil in jug as many times as you can be bothered = cleanish jug and mixed fuel container. DO NOT mix up containers with the one for the chainsaw, strimmer etc Safety precautions; The above methods should not be performed in the kitchen next to a lit gas cooker! GJ
April 12, 201214 yr Do y'all not have these Ratio Rite mixing cups, in the UK? http://www.amazon.com/Kam-Tech-Ratio-Rite-Cup-150108/dp/B002OQDO4C By far the easiest way. Different scales along the side for fuel amount versus ratio.
April 13, 201214 yr I got a little bottle of 2 stroke with my husqvarna chainsaw and that is exactly 130ml which is right for 10 ltres.

Different scales along the side for fuel amount versus ratio. Just ordered one as I find the syringe method a total pain in the a***, too fiddly. Thanks for the link, found a UK supplier eventually! £5 delivered.
April 13, 201214 yr What's such a pain in the bottom sucking up 63ml of oil into a syringe, squirting it into a 5ltr can and shaking it? The mind boggles...
April 13, 201214 yr Author Alright it's not that bad, but I like the idea of a mixing jug, it should be a cleaner, more accurate job. Edited April 13, 201214 yr by rallymadsam
April 13, 201214 yr Buy a 4RT its easy then its 50% petrol mixed with 50% petrol Other people have used a 60% and 40% ratio and it dosen't really make any difference to how sweet the motor runs!!!!!

Granted. I have done the 4-stroke route. I found the oil filter changes to be far more of a pain in the rear than mixing 2-stoke fuel. Especially, with the Ratio-Rite mixing cup.
