Review on 🚤 Enhance Your Marine Experience with Pennzoil 550045220-3PK 1 Gallon Marine Premium Plus Outboard – 2 Cycle 1 gal. jug by Sean Maples

Burns well in my device. A ratio of 32:1 to 50:1 is recommended. At around 40:1 there is no noticeable blue smoke coming out of the tailpipe. A four-stroke engine works well at a ratio of 100:1 to 300:1. From 300:1 there is no noticeable difference to normal petrol. Below 100:1 is not recommended as this engine does not require as much lubrication and will only foul the spark plugs and valves. A ratio of 160:1 is optimal for a 4-stroke engine. This increases lubrication of the MPG and valve/upper piston; The engine runs cooler and has less vibration.
