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.
SAE 10w30
SAE 10w30.
SAE 10w30 full synthetic.
Yes you can.
SAE 30 weight in the summer or SAE 10w30 if you use the engine in cool temperatures.
SAE 10w30. I recommend you use synthetic oil in any air cooled engine.
SAE 10w30 Full Synthetic any major brand.
Full synthetic SAE 10w30.
SAE 10w30 synthetic is a great choice.
Most manufactures recommend SAE 10W30 or 30W. I recommend you use 10W30 Synthetic in any air cooled small engine.
SAE 30W in the summer and SAE 10w30 in the winter. I recommend you use 100% synthetic oil in any air cooled 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.
