What happens if you use 15w40 instead of 5w40?

Both 15w40 and 5w40 have a viscosity of 40 degrees. But when it’s the dead of winter, everything doesn’t remain usual, and the changes can vary. While starting your engine, 5w40 will have a lower viscosity other than 15w40.

In short, 5w40 gives easy and quicker lubrication in cold temperatures. If you use 15w40 instead of 5w40, you may not get a similar appliance of smooth flow of oil.

Can I put 15w40 in my petrol car?

The main purpose of 15w40 is to enhance the performance of diesel engines. Moreover, there are extra additives that are particular but not detrimental to gasoline engines.

As I mentioned before, 15w40 is quite thicker than 5w40. And there will be no problem if you want to use it for your petrol car. Even petrol cars adapt with thicker oils compared to thinner oils.

Can you put 15w40 in a 5w30 engine?

Putting 15w40 in a 5w30 engine will increase the fuel consumption of your engine. That is because your engine’s crank will get overloaded but won’t blow off.

Your engine will cause wear rapidly due to insufficient oil flow. And the moving parts will be lagging in exhibiting good performance.

Also, remember that the synthetic additives here can damage your catalytic converter being out of range.

Is 15W-40 oil only for diesel engines?

15w40 oil suits best with diesel engines. The diesel engines have an oil formation of additives that the gasoline engines can’t catch.

But there is nothing necessarily bad even if you use 15w40 on gasoline engines.

While typically, people most often use this oil on diesel engines to boost their vehicles’ performance. And a complete success in over-the-road diesel trucks is sure to be noted so far.

Does diesel oil damage gas engines?

Diesel oil is always not a successor for gas engines. It would be best if you put them in a higher temperature and higher oxidation rates.

But the sulfur deposits, fuel soot, acids, and other deposits are usually not found in diesel oils. And thus, your automobile engines don’t find a relevant option to turn on.

The reason is, diesel oils fail in some critical areas when you use them on gasoline engines.

Will 5w40 hurt a 5w30 engine?

On a pitched note, I will recommend you choose 5w30 for an extensive engine power next to 5w40. Or if you find it too expensive or unavailable, there will be no problem if you choose 5w40.

Moreover, it will not cause any hurt or damage to your engine parts.

But make sure the oil pressure is not heavy so that your engine gets a soothing flow of oil.

What oil is thicker 5w30 or 5w40?

5w40 is thicker than 5w30. The viscosity range of 5w30 is 9.3 to 12.5mm2/s. At the same time, the viscosity range of 5w40 is 12.5 to 16.3mm2/s. It means the 5w30 has more viscosity than 5w40, and it’s a sign of more thickness in the oil. So, according to the viscosity range, 5w40 is thicker than 5w30.

Which oil is thicker 10W40 or 15W40?

Motor oil grade represents operating temperatures, and the weight of oil is cold. When the temperature rises, viscosity or thickness will also rise at the same time.

Coming to 10W40 oil, it is a thicker option in the cold in comparison to 15W40. But there will be no change in the viscosity of both when the temperature is high.

Again, 15W40 attempts to be heavier than 10W40 with more shear resistance if you see it in a cooler condition.

Which oil is better 20W50 or 15W40?

It is best to use 15W40 for your new engine, which takes 15W40 effectively. But if your engine wears down 300000 miles that takes 15W40, then 20W50 will be the king for usage.

Because here you get thicker lubrication, and it sticks to your bearings. And the rest of the moving parts around makes your engine not wear out as fast.

Moreover, the 20W50 is a bit heavier than the 15W40 and consumes more oil.

Final Verdict on 5w40 vs15w40

In a juxtaposition of 5w40 vs 15w40, the article must have got the shot that you are looking for. What type of viscosity, ability, and thickness you want you must go for that one. In this imperfect world, it’s hard to find the perfect item but not impossible. Rather it will be best if you get the true mint of engine oil with a real recommendation.

Likewise with low viscosity and good lubrication 5w40 wins the crown. Though 5w40 lacks somewhere, 15w40 fills on that part, and the same goes for the other.  And on a comparable note, this engine oil handles better than 15w40.

So what about giving it a second thought? Not being late, grab your perfect engine oil and serve your engine the best.
