No
10W30 can be used, but SAE30 is best. 10W30 can run a bit hot, in warmer climates.
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.
There is no difference in viscosity. A 10w30 full synthetic is the same as a 10w30 blend.
If it has a Briggs and Stratton engine you need SAE30. If it is a Kohler it uses 10W30.
It is a little thick. You should use sae30 or 10w30 (on cold temperature)
I am not sure what you are wanting to use the oil for. If it is for a lawn mower, most of them take either 10w30 or SAE 30. They are not the same oil. You will need to refer to your engine manufacturer for the oil required for your engine. Normally most Briggs and Stratton and Tecumseh engines use the SAE30 oil. While most Kohler engines use 10w30.
The first number is the oil viscosity when the engine is cold, and the second number is when the engine reaches its operating temperature. 10w30 is more viscous, and 10w20 is generally used for motorcycles.
The weight of the oil when it is cold. The 15w is a thicker oil than the 10w when it is cold.
Briggs & Stratton small air cooled engines use SAE30 weight oil or SAE 10w30 if they will be operated in cold conditions. I highly recommend you use Synthetic oil in any air cooled engine.
SAE 10w30 is better for lower temp and SAE 20w40 is the opposite better hotter temps.Thanks
The main difference is cold flow ability. The 5w30 will flow better when cover over the 10w30. Once operating temperature is achieved, they are virtually the same.
