Nice......but....back on subject....if you are using one of those "one shot" stihl options...just use 50:1 as it is damn easy as long as you use that fuel in around two weeks.

Personally, I don't get through that much mix, even when I was running the business so used a small measurement cup and a 5l petrol can and measured around 500ml of fuel at a time and just "over egged" it a bit to get around 45:1 mix which worked in my workshop.

As I said, it depends how much mix you use and how you mix it. 

50:1 is fine and it is what the OEM recommends, just ensure a strato engine gets semi or full synthetic as they use less fuel meaning less oil to lube the main bearings in this type of machine. Keep the Red Stihl for older machines.

Everyone will have his own methods and old mix kills two strokes so keep it fresh and only mix what you need for the next week or two.

Strato engine? Is that the same as 2 mix engine?

Think it was a thing Komatsu Zenoah developed to reduce emissions & use less fuel then husky called  x torq and stihl  2 mix.

I believe the original project was called air head.

Well, with less alcohol inside me and a bit more time than I had last night, the exact figure to convert a 50-1 mix oil to 45-1 in 5 litres is 111.111ml, so yes you are correct to state 110ml to the nearest 5ml. My mitigating circumstances for quickly suggesting it would be 105ml are as follows;

 

I was supping neat jack on a regular basis.

 

It was a quick, rough fag packet calculation...albeit 5/6ml out.

 

In 23 years of selling oils as a main dealer, no one has asked the original question, and if they had, I wouldn't have worked it out for them anyway, as I would have advised against it. So, no it shouldn't come as a surprise that I and no one else in my dealership would 'know the sums to get them right' as the question wouldn't and shouldn't arise.....we advise the correct, and not the incorrect fuel ratio as per the manufacturers instructions. Advising a customer as to how to 'incorrectly' alter the recommended ratio is opening a whole can of dealership worms as to liability, and we all know that customers never make mistakes and are happy to blame everyone but themselves nowadays

 

The correct answer from my point of view, should be to always dilute it the way the manufacturer intended. That is correct in the first instance
