Briggs & Stratton 100005 SAE 30W 4-Cycle Small Engine Oil, 18 oz. Bottle

This Briggs and Stratton Lawn Mower oil is the correct product to use when servicing their engines. It is the correct blend and viscosity oil to insure proper lubrication of your engine. There less expensive oils out there however can you really be sure they are the correct spec to use safely? This oil is a little pricy for the volume you get in the bottle but it's worth the cost to insure you are getting the proper protection.

I can't tell you how nice it is to have a small engine oil in the proper size to be able to just dump and go with the Briggs and Stratton engines when it's time for annual maintenance. For those who don't know, small engine oil is different then regular engine oil as it is designed to tolerate higher heat as the engines are air cooled and has more anti wear additives like zinc. Using the correct oil while greatly extend the life of any engine.

This is best for small engines seeing seasonal use such as lawn mowers and other small engines. If you are in a cold climate and use the small engine year round, use 5w-30w synthetic. This gets gummy during the winter and is good for keeping your cylinder walls coated with a thin oil layer for long periods of storage, it does not promote easy starting due to those same properties.

I grabbed this 48‑ounce SAE‑30 oil for my Snapper riding mower's seasonal tune‑up, and it's been a quiet little win—the bottle size is perfect for small engines, giving me enough to fill the crankcase and top off the dipstick without leaving half‑used containers cluttering the garage that I've noticed. It's straight‑weight SAE‑30, exactly what the manual calls for in summer heat, and it keeps the Briggs engine running steady without overheating that I've noticed. I can't promise it'll turn an old tractor into a speed demon, and you still have to remember to check your dipstick, but for a basic, dependable fluid that matches manufacturer recommendations, it does exactly what I needed that I've noticed. Nothing flashy or overhyped—just a solid, no‑drama maintenance staple that keeps my yard gear running smoothly, and sometimes that's the win that matters most, and that easy, no‑fuss consistency is why I'm glad I grabbed it.

It gets the job done, used it for years without any issues. Im sure there is better out there of course, didn't know that during extreme hot temperatures its actually suggested to use a different kind of oil, learnt that while reading a manual to a new tractor. Taste a little funny though would not suggest eating food after getting some on your hands, unless the food was sour prior.

I purchased a l lawn mower that stated you don't need to change the oil, just top it off as it burns off. A couple years later the oil was still at a correct level but looked rough so it was time to go against what the manufacturer was pushing and change the oil. This stuff worked great

whoever put this in a walmart bag put it in leaking and it got spilled in the car of the delivery driver and i did receive a full bottle of motor oil.

Perfect for my Troy Bilt horse riding lawnmower. You'll need 2 for a complete oil change will a little left over in the second bottle for top offs if you need to

I prefer to use the Briggs %26 Stratton 100005 SAE 30W 4-Cycle Small Engine Oil in the gas lawnmowers. It is a perfect and correct size container, easy for me to handle, measure, pour and change my own oil and filter as necessary and needed.

Needed oil for my mower and found it here at a good price. Lots of choices out there but got an excellent price and didn't leave the house together it.
