straight 30w for 4 stroke
10w30 oil is what is recommended
10w30 any major brand.,
2-cycle engine oil. This is different from the oil you would put in a car. Look for it in the lawn care section of your department or hardware store.
the best would be to use 10w-30 synthetic oil all year long
30wt oil of any brand will work
10w40 motor oil will work fine!
I have a 1999 Mercury 2stroke 5HP outboard and the owners manual states 50:1 Gas/Oil mixture.
SAE 10w30 synthetic oil.
one quart. Use the oil dipstick!!
10w40 will work fine!
