Which oil is thicker SAE 30 or 40?

3. What’s The Difference Between SAE 30 And SAE 40 Oils? SAE 40 oil is a slightly thicker oil than SAE 30 and will thin out slower at high temperatures.

Can I mix SAE 30 with 10W40?

No. SAE 30 is a single viscosity motor oil. Only multi viscosity motor oils only should be used in any car. 5W means that the oil at cold temperatures acts like a 5 weight thinner oil.

Is 30w thicker than 10W30?

No 30w stays 30 weight at all times. 10w30 acts like 10w and is thinner in a cold engine, and like 30 weight, thicker, when the car is hot.

Which is thicker 5w 30 or 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 30 the same as 10W40?

High Temperature Viscosity This is often regarded as the engine’s operating temperature. This means that at 100oC, 10W30 engine oil has the viscosity of an SAE 30 single grade oil, and 10W40 oil has SAE 40 viscosity. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises.

What is SAE 30 oil?

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. Sometimes so thick that it cannot flow if it is cold enough out. The W means winter.

Is SAE 5w 30 oil the same as 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.

Is SAE 30 same as 10W-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.

Can I use 30w instead of 10W30?

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 put 10W40 in 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.
