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.
No
10W30 can be used, but SAE30 is best. 10W30 can run a bit hot, in warmer climates.
It is a little thick. You should use sae30 or 10w30 (on cold temperature)
If it has a Briggs and Stratton engine you need SAE30. If it is a Kohler it uses 10W30.
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.
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.
Yes you can.
yes,it will not hurt it
If the manufacturer of the lawnmower specifies only SAE 30 then do not use SAE 10W-30. However on most mowers you can use either weight. I highly recommend you use synthetic oil in any air cooled engine.
Use exactly what Honda recommends and nothing else which is SAE 10w30 for general use. Using anything else may void your 7 year warranty. I recommend you use synthetic oil in any air cooled engine.
Use exactly what the manufacture of your vehicle recommends and nothing else. To do otherwise is foolish.
No, absolutely not.
