Key role in your engine΄s long life and trouble-free performance possess the oil that is being used. Both conventional and synthetic oil can be used, depending in owners discretion. With all the different types of oil on the market, they often start to  sound the same. Many owners simply follow the guidelines the manufacturer sets up, and don’t think too far beyond it.

       However, there are some key differences between types of oil. For one thing, some are meant for two-stroke engines while others are optimal for four-stroke use. The oil used in crankcase compression two-stroke engines, 2- stroke oil, is much different than what owners would use in a four-cycle engine. The oil-base stock is either petroleum, vegetable, semi-synthetic or synthetic oil and is mixed with gasoline at a ratio ranging from 16:1 to 100:1, unlike a four cycle which doesn’t need fuel mix with oil.

        There are RC pilots who believe that using synthetic oil instead of regular oil is akin to using margarine instead of butter. It may look the same, but does it really do the trick? Many synthetic oils are made with ash-less components to prevent fouling. Also the anti-gel properties are better than the regular oil.

       When comparing synthetic oil to regular mineral oil, there is no doubt that synthetic oil is superior. But when synthetic oil can cost double the price of regular mineral oil, it’s important to consider whether the benefits of using synthetic oil apply to you. There are two main benefits that synthetic oil holds over mineral oil: ability to withstand heat, and flow better at cold temperatures. Heat is what breaks down oil, and at some point, forces the oil to lose its lubricating properties which necessitates an oil change. The first few seconds following ignition are some of the most important for engines. If the oil in your engine freezes, it can cause serious damage to the engine. Synthetic oil, unlike mineral oil, will not freeze.

       Safety Tips

         1. When preparing fuel/oil mixture for your gas engine, always follow the manufacturer΄s specifications about mixture ratio.  

         2. 87− 93 Octane gasoline with a 30:1 gas/2-stroke (2-cycle) oil mixture is commonly used.

         3. Prepare the fuel mixture in a well ventilated area.

         4. Use a dosimeter or a mixing fuel bottle to measure the exact amount of oil. 

         5. Store the fuel in well sealed can away from sources of heat and the reach of children.

         6. Most helpful is a 2 stroke fuel-oil mixture chart

             or an online mixture chart.
