A 10w40 motor oil is a thicker starting oil than a 5w30 motor oil. Therefore, 10w40 oil adheres more strongly to moving engine parts than low-viscosity 5w30 oil.
Can I use 10W40 instead of 5W30?
If your car’s recommendations say you should use 10w30, that means you should not use 5w40 as it behaves differently when cold or at operating temperature. The first numbers 10W and 5W refer to the cold viscosity. The lower the number, the thinner the oil is when cold and vice versa.
Why are you using 10w30 instead of 5w30?
10w30 is thicker than 5w30 because it has a higher viscosity at low temperatures. Motor oil flows slower than 5w30 during the cold season. Thicker or higher viscosity metallic oil will have a better seal compared to lower viscosity oil. Thicker oil provides better lubrication of the engine and engine parts.
What happens if I use 10w40 instead of 10w30?
The basic fact that “40” is greater than “30” tells you that. If you put 10W40 in an engine rated for 10W30, the “thicker” oil would cause friction in the engine and increased stress on the oil pump . The car should do more work to get the oil around the engine block.
What happens if I use 10w40 instead of 5w20?
And a 10W40 would void your warranty… just so you know. With a 5W20 engine. You can use 0w20 oil in cold weather (I use 0w20 oil) and that would be fine for Ford. (They won’t say it’s good, but they’ll still honor the warranty..)
What happens if you use 10w40 instead of 5w30?
If you use 10w40 instead of the 5w30 specified by the manufacturer, the viscosity of the 10w40 you are using will be higher and the oil will be thicker than specified in winter. In addition, the oil viscosity is higher in summer and the oil is more viscous than specified.
Which is better 5w30 or 10w40?
The difference lies in the viscosity at different temperatures. … 5w30 oil flows better than 10w40 oil at low temperatures. This means that 5w30 oil protects the engine better at low temperatures, usually when the engine hardly starts or in weather conditions such as winter.
Can we go from 10w40 to 5w30?
All engine oils are compatible. When you switch brands you end up with a blend of additives that doesn’t hurt, but doesn’t give you all the performance of a premium oil.
Will using 10W40 on an engine that requires 5W30 affect my engine, if so how?
However, there is very little chance that using 10w40 in your vehicle that specifies 5w30 will cause any noticeable negative results. If you read your service manual, they might even recommend 10w40 for excessively hot climates. You may notice higher oil pressure and slightly better fuel economy.
Should I use 10w30 or 5w30?
The only difference between these two oils is cold fluidity: a 10w30 oil will move slower than a 5w30 oil during a cold start. … If the oil is in the engine in the winter and you live somewhere that gets cold during those months, use 5w30 oil. If it’s only in the engine in the summer, use 10w30.
When should I switch from 5w30 to 10w30?
You don’t necessarily have to switch to 10W30. The 5W and 10W are the numbers that give you the low temperature performance of the oil and the second number gives you the high temperature performance. The oils differ only in their cold-weather viscosity. If you never see temperatures below zero, 5W30 or 10W30 is fine.
What happens if you use the wrong weight of oil?
Using the wrong oil can compromise lubrication and shorten engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil will not harm the engine, but there is no benefit in doing so.
Can I mix 10w30 and 5w30?
Can 5W30 and 10W30 be mixed? The simple answer is YES, you can not only mix the two oils because they are the same weight, but because it is safe to mix two different motor oils. However, we do not recommend mixing motor oils. … Because the law does not guarantee any advantage over using just one type of oil.
What happens if you use 10w40 instead of 5w30?
If you use 10w40 instead of the 5w30 specified by the manufacturer, the viscosity of the 10w 40 you are using will be higher and the oil will be thicker than specified in winter. In addition, the oil viscosity is higher in summer and the oil is more viscous than specified.
What is the most economical 10w30 or 10w40 motor oil?
Technically, a lighter oil offers better fuel economy because its lower viscosity makes it easier to move through the oil system. However, the difference between 10W30 and 10W40 is indistinguishable.
When to use 10w40 oil?
10w40 is best for hot weather or heavy loads. If you expect your vehicle’s operating temperature to be higher than most occasional cars, then using 10w40 is recommended. 10w40’s higher viscosity at high temperatures reduces wear when you put more pressure on your vehicle’s engine. 6
What can I use instead of 10W30?
Yes. 5w30 and 10w30 are both 30 weight oils and will be exactly the same thickness in your engine when it is at operating temperature. 5w30 is better because it has less cold or cold thickening.
Is it wrong that I put 10w40 in my engine that needs 5w30?
If your manual recommends SAE 5W30 AND SAE 10W40 you can certainly switch, but the only difference is slightly better fuel economy and a little harder cold starts.
Is 5w20 the same as 10w40?
For an oil to be considered a multigrade oil it must meet two viscosity specifications and the viscosity grade consists of two numbers such as 5w20 where 5 is low temperature or winter viscosity and 40 is high temperature or summer viscosity.
What happens if you use 10W40 instead of 5W 40?
10w40 is thicker than 5w40 ONLY when cold. At operating temperature it is exactly the same. Multi-viscosity, low W-index oils are specially formulated to flow better at very low temperatures and therefore lubricate better. There is no need to use a 5w40 if the vehicle only requires 10w40.
Which oil can I replace with 5W 20?
The 0w or 5w refers to cold temperature pumpability. Therefore a 0W would flow more easily than a 5W and could be an acceptable substitute. Therefore, an SAE 0W20 should be used as a replacement for the SAE 5W20 application. ** Offers the same protection as 5W, but also offers faster throughput and better fuel economy.
A 10w40 motor oil is a thicker starting oil than a 5w30 motor oil. Therefore, 10w40 oil adheres more strongly to moving engine parts than low-viscosity 5w30 oil.
Can I use 10W40 instead of 5W30?
The recommended oil viscosity for your vehicle is 10W40 according to Kia literature. If you drive the vehicle in exceptionally cold weather well below 32 degrees, you can use 5W30 oil, but 10W40 is still perfectly usable when the outside temperature is below freezing.

What happens if I use 10W 40 instead of 10W30?
The difference between 10W30 and 10W40 is the high temperature viscosity. Obviously a 10W40 is thicker than a high temp 10W30. … Using oil with the right viscosity will make starting easier, reduce friction and slow down wear.
Can you mix 10w40 with 10w30?
Yes, you can mix 10W30 with 10W40 as long as the engine is running on 10W30 and 10W40. On some high performance engines, the 40 may be too thick on some engines. Most engines today use much lighter oils to save fuel and because of engine specifications.
Can I use 10w40 in Activa?
You can definitely use 10w40. You will get an even better result than 10w30 in the summer. So use 10w40 but make sure you get the best brands. A bottle of Motul 7100 10w40 lasts up to 5000 km on your asset.
