If you’ve ever owned a 2-stroke outboard motor, you know that the proper oil-to-gas ratio is essential for keeping your engine running smoothly. But what happens if you put too much oil in the mix?
The most common problem that can occur when too much oil is added to a 2-stroke outboard is engine seizure. This occurs when the piston and cylinder walls become coated with an excessive amount of oil, causing them to stick together and prevent the engine from turning over. If this happens, it’s likely that the engine will need to be disassembled and rebuilt in order to get it running again.
Another issue that can arise from adding too much oil is fouled spark plugs. When there’s an excessive amount of oil in the combustion chamber, it can coat the spark plugs and prevent them from firing correctly. This can lead to poor performance or even complete engine failure.
Finally, adding too much oil can also cause your outboard motor to run hotter than normal. This is because the extra oil acts as an insulator, trapping heat inside the engine and preventing it from dissipating properly. This can lead to premature wear on internal components and even cause catastrophic failure if left unchecked.
It’s important to remember that every 2-stroke outboard motor has its own specific requirements for fuel/oil ratios, so make sure you consult your owner’s manual before adding any additional oil to your mix. If you do find yourself with too much oil in your tank, don’t panic – just drain some of it off until you reach the correct ratio and then start up your engine again.
