Mixing tips

Add oil to an empty can first, then fuel on top — it mixes faster and more evenly.

Shake the can thoroughly before every fill-up, not just when you mix it.

Use fresh fuel — pump petrol starts losing volatility after roughly 30 days.

Label the can with the ratio and date so nobody guesses later.

Always check your engine manufacturer’s recommended ratio before mixing — this tool is a guide, not a substitute for your bike or equipment’s handbook.
