I buy mine off Amazon, and add 2oz to ever fill-up from empty.

i run a 50/50 mix of redline fuel additive and ASHLESS 2 stroke NON synthetic oil, i use about 250ml per full tank of gas , engine is suuuuper quiet runs silky smooth, no smoke and o2 sensor has a perfect grey color to it, there is no buildup of any kind ,reason for non synthetic is that synthetic 2 stoke oil does NOT burn, it WILL crude up your o2 sensor and make higher amount of carbon buildup, i personally run SHELL marine ashless its cheap and burns completly without leaving residue , the injector noise is completly gone and in general the engine runs smoother, this is not enought to actually produce smoke it equates to a 1:300 mixture, which is nothing , the redline injector cleaner seems to work really well, so i just get a bottle pour 1/2 of it into another container and it has 250ml markings on it so its easy . i top that 1/2 up with 2 stroke oil and bingo,
