How to calculate 2-cycle oil mix
Mix your own 2-cyle oil for your personal watercraft and other 2-stroke engines. (jet ski image by razorconcept from

Two-cycle or 2-stroke engines run lawn care equipment like chainsaws, lawnmowers, leaf blowers and brush cutters, but they also power recreational equipment like motorbikes, snowmobiles and personal watercraft. Instead of buying premixed 2-stroke fuel, you can mix your own to make sure that it's fresh when you need it for optimal performance. This is especially important when it comes to fuelling your recreational vehicles. It's a good idea to keep extra 2-stroke fuel on hand because there's nothing worse than running out of fuel for the lawnmower in the middle of mowing the lawn.
