Is SAE 5W-30 the same as Synthetic 5w30?

Is SAE 5W-30 the same as Synthetic 5w30?

The petroleum base oil alone may have the properties of an SAE 5 grade oil. When it’s brand new, a 5W-30 conventional motor oil acts exactly like a 5W-30 synthetic motor oil. Over time, however, the chemical additives used in the conventional oil to alter its properties begin to break-down, vaporize, or get used up.

What is the difference between 5W-30 and 10w 40?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Is SAE HD 30 the same as 5w30?

5w30 is mostly used on cars and trucks. SAE30 is a straight 30 weight oil used on your lawn mower and other 4 cycle outdoor equipment. SAE30 weight oil is rated only at the full operating temp of the engine. This means it is much higher than 30 when cold.

What happens if you put 5W-30 instead of SAE 5W-30?

It is not recommended. Although they both have the same winter rating of 5, the thickness (viscosity) of 5w30 is a bit higher than 5w20. That means your engine’s at stake for using the high viscosity oil. Cause they’ve made the engine and knows better.

Can I use SAE 5W-30 instead of 5W-30?

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.

What happens if I put 10W40 instead of 5W-30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

What happens when you use 10W40 instead of 5W-30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Can I use SAE 5W-30 instead of SAE 30?

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 HD SAE 30 in my lawn mower?

No, it is not recommended. Most engines that call for SAE 30 are older models of mowers with engines designed for straight weight oil.
