What oil is comparable to SAE30?

SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100. As you can see, there is a bit of a difference between ISO 68 and SAE 30. The viscosity of the fluid largely determines the oil temperatures within which the hydraulic system can safely operate.

Is 10w30 oil the same as SAE 30?

SAE 10w30 oil has 10w thickness at low temperatures, but SAE 30 is at high temperatures. In the straight SAE, 30 doesn’t and can have immense Viscosity and helpless pumpability at low temperatures. As SAE 10w30 is not thick in low temperature, while SAE 30 is in high temperature.

Is 10W-40 same as SAE 30?

Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. This oil type remains thicker at 100°C/212°F compared to an SAE 30 high-temp flow grade and is more suitable for warm weather.

Can I use SAE 10w30 instead of SAE 30?

Nope. SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for ‘Winter’. Note that these viscosities are relative, and standardised numbers and no absolutes, the oil doesn’t get thicker when it’s hot, it gets thinner.

Can I use 5w40 instead of SAE 30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

Can I use 10W30 motor oil in my lawn mower?

10W30 is a common motor oil grade suitable for many lawn mowers. Your owner’s manual will tell you the exact grade required, but in almost all cases 10W30 is the right stuff for a four-stroke engines. Any brand of oil that’s suitable for cars or trucks will work fine in your mower.

Can you use 10W40 instead of SAE 30?

Naji Abou-Haydar has a very good and concise answer, but most SAE 10W-40 oils will work perfectly in an old engine designed for SAE 30.

Can I use 5w 30 instead of SAE30?

5w-30 is fine to use. It has the same flow rate as SAE30 at normal operating temps. The way oil works is, the first number is flow rate at ambient temp. The second number is flow rate at operating temp of the engine.

Can I use 10W-30 oil in a lawn mower?

Can I use SAE 5w30 instead of SAE 30?

Originally Answered: Is SAE 30 the same as 5w30? No. SAE 30 is a single viscosity motor oil. Only multi viscosity motor oils only should be used in any car.
