Experienced gardeners share their insights in answering this question :
Either through the inlet valve stem seal, or the needle in the carb is leaking, start by fitting an inline fuel tap so there is no chance of fuel leaking when the machine is stood.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
What causes fuel to leak into my engine oil? The fuel shut-off valve isn`t closed properly. Fuel float in the carburetor being stuck in the open position due to gumming (caused by stale fuel) or debris.
Usually the problem is in the float bowl. The float needle and seat need replacing. When it`s faulty, gas doesn`t stop flooding the carburetor and gets into the cylinder and mixes with the oil. You must also change the oil when this happens as your oil is now ruined.
Use Briggs & Stratton SAE 30W Oil above 40°F (4°C) for all of our engines. Check oil level regularly.
Don`t overfill the crankcase when adding oil. Too much oil can damage the engine. Briggs & Stratton offers oil specially formulated for your mower and other equipment.
A small amount of oil will not cause any major damage. However using 2T oil or mixing any oil with fuel in a 4 stroke is neither required nor recommend specially in modern vehicles. It will increase emissions. It may cause premature carbon build up in the engine.
Diesel fuel dilution of the engine oil occurs due to internal leakage of the fuel injection system. Causes vary with different engines, but can be related to sealing ring failure, loose connections, faulty fuel injectors, or even the result of extended periods of idling.
What Happens if I Use Too Much Oil? Or Not Enough? Using the proper oil-to-gas ratio is important, but if you`re off, it`s better to mix too much oil into your engine than mixing too little oil. Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power.
If carburetor problems are causing fuel to mix with your oil in the crankcase, you should perform a thorough cleaning. Find out how to clean your small engine carburetor.
Two-stroke (or 2-cycle) engines require a mixture of fuel and oil be added to the fuel tank. This mixture results in both engine combustion and lubrication. Operating a 2-Stroke engine on gasoline alone will result in engine failure.
Lawn mowers that run on internal combustion engines burn gasoline as fuel, and like any engine with metal parts, your lawn mower requires oil to lubricate the pistons and other moving parts. The oil reduces friction between moving metal parts and protects the life of your engine.

There`s not much difference between 10W-30 and 10W-40 motor oil. What sets them apart has more to do with temperature fluctuations and engine load. For moderate weather, either engine oil grades should work fine.
While automotive engine oil, such as 10W-30 or 10W-40, can be used in a lawn mower engine, it is generally recommended that SAE 30 motor oil be used.
Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 or 15W50 oil in all temperature ranges. We recommend the use of Briggs & Stratton Synthetic Oil.
Common signs of engine oil overfill include:
Smell of burning engine oil. Smoke from the engine compartment. Smoke or black exhaust from the tailpipe. Unusual noises coming from the engine.
If the oil level is a little above the full mark, that shouldn`t cause problems. If it`s overfilled by half a quart or more, or foam shows on the dipstick, the best fix is to have the oil drained and refilled to the proper level.
For a mixing ratio of 1 : 50 you need 5 litres of high-octane gas and 0.10 litres (100 ml) of STIHL two-stroke oil.
Excessive viscosity will affect pressure, or if it`s too little or too clear, the engine will have to work harder than necessary. For diesel and gasoline engine oil the car user shouldn`t be mixed it shouldn`t even be done. Except in an emergency, which should be taken immediately to prevent engine damage.
All diesel engines burn some oil as a normal part of operation. This can be a problem in modern turbodiesels…
If you have put too much oil in your car, you should drain the excess oil. If you`re not confident doing this, you will need to get your vehicle towed to a mechanic – driving it could damage the engine, requiring expensive repairs.
Using a 4-stroke oil in a 2-stroke engine can therefore disrupt combustion and cause smoke formation and engine degradation.
Use a 40:1 two-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment? Use the 40:1 mixture.
Once a seal is broken the fuel has a storage life of six months at 20°C or three months at 30°C. As stated earlier, “fresh is best” so be sure to mix smaller batches more frequently. Head over to the front page and you`ll find a handy calculator to help you get your mix right.
