12/40 is equivalent to 3/10 in its simplest form
If you mean 40 to 12 and 120 to 36 then they are both equivalent and in their lowest terms they are equivalent to 10 to 3
It is: 30/40 = 3/4
.40
10/25 = 2/5 = .40 = 40%
The user's guide to my 130 series B&S engine (garden cultivator) says: 10W-40 can be used if 10W-30 is not available at your location. So, if you fit to the 10W-30 oil temperature interval then 10W-40 can be used. On the other hand lawnmower is usually used at spring-summer temperatures so why not to use SAE30 oil?

So, if you fit to the 10W-30 oil temperature interval then 10W-40 probably can be used. I have been using SAE30 up to now. Now I am planning to switch to 10W-40 as I want to use the machine in the winter as well.
The main difference between 10W-40 oil and 15W-40 oil is that 15W-40 oil has a higher viscosity than 10W-40 oil. 10W-40 oil allows the engine to run freely.
10W-40 10W-40
10w-30 or 10w-40 oil
Yes
Yes it is fine to use 10W-40 oil
Viscosity. 5W-30 is a "thinner" oil than 10W-40 is.
The 10W 40 oil is thicker and is thought by many to be more efficient.
i would suggest 10w 40
10w-40 oil
The recommended oil for a Ford 300 is Shell Rotella 15w-40. If cost is an issue, regular 10w-30 or 10w-40 oil can be used.
