30w refers to the viscosity of the oil. 10/30 is a mixture with 10w wich is more viscous. The reason multiviscosity oils are used is so that when the motor is first started the lower weight oil will get to the top of your engine more quickly. This helps lube overhead cams and internal parts while the 30w oil is still too dense ( too cold ) to get to the top. Most of the wear on your motor happens during the initial startup. If your repair manual recommends 10/30 you should use it.
It can vary between 30W and 10W30. L-heads use 30W, OHVs often use 10W30.
10w30 synthetic for year round use, and 30w for only summer use.
I would not recommend it, stick with the straight 30W.
Use 30w synthetic or 10w30 synthetic. 30w is preferred.
Most manufactures recommend SAE 10W30 or 30W. I recommend you use 10W30 Synthetic in any air cooled small engine.
If the recommended oil is SAE30 why would you use SAE 10W30? Some mowers recommend either of these weights but if your recommends 30W then using 10W30 will cause it to use oil.
flatheads normally 30w overheads 10w30 high detergent
Usually no difference except that later model vehicles require a multi-viscosity oil (5w-30, 10w-30. etc) while the regular 30w is recommended for small engines such as a lawn mower.
The boiling point of 30w oil can vary depending on the specific composition of the oil. Generally, the boiling point of motor oils, including 30w oil, can range between 400-600 degrees Fahrenheit.
Use any major brand 30W or 10W30 or 15W30 motor oil. Just be sure to stay within the manufacturer's suggested maintenance schedule for oil changes.
10w30 for year round use, and 30w for only summer use.
Yeah you can but i would just use straight 30w either way its not going to hurt it
