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%
To find what is equivalent to 12 over 40, we need to simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 4. This simplifies the fraction to 3 over 10. Therefore, 3 over 10 is equivalent to 12 over 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
SAE 30 motor oil is a single-grade oil suitable for warmer temperatures, while 10W-40 is a multi-grade oil designed for a wider range of temperatures. Using SAE 30 instead of 10W-40 may provide insufficient protection in colder conditions, as it lacks the lower viscosity of the "10W" rating, making it harder for the oil to circulate when starting in cooler weather. Additionally, if your engine is designed for multi-grade oil, using a single-grade oil like SAE 30 could lead to increased wear and decreased performance. Always refer to your vehicle's owner manual for the recommended oil type.
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
