Can I put 5w30 instead of 5w40?

Can I put 5w30 instead of 5w40?

If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.

What is 15W-40 engine oil?

As a 15W-40 viscosity grade, it flows like a 15 weight oil from start up in Winter, but provides the protection of a 40 weight once the engine reaches full operating temperature.

When should I use 10W-40 oil?

Using an oil with a low viscosity can lead to excessive metal to metal contact between moving parts. Using the correct viscosity oil eases starting, reduces friction, and slows wear. For even more effective start-up protection, use a synthetic 10W-40 instead of a conventional 20W-50.

What does the 10 in 10W40 mean?

The designation “10W-40” indicates a multigrade oil that is toward the low end of the SAE scale in cold weather, but at the upper end in hot conditions. 10W-40 oil is therefore good for a wide range of weather conditions.

Can I use 5w30 instead of 10W40?

The main difference between the 5w30 and 10w40 is the viscosity difference at different temperatures. The one, 5w30, will be able to flow better when the temperatures are low than the 10w40. So at a lower temperature, the 5w30 oil will be the best to protect the engine.

Which is better 10W40 or 20W50?

10W40 is not better than 20W50 for high mileage. The difference between 10w40 and 20w50 is simply that the latter is thicker. As far as gas mileage goes, no oil will improve your gas mileage by changing from 10W40 to 20W50 or vice versa.

Which is better 10W40 or 15w50?

Viscosity or thickness of the oil increases with rise in temperature. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. 10W40 oil will perform cold starts better than 15W40 oil.

Is it OK to use 15w50 instead of 10W40?

So the 15W-50 oil is “thicker” at cold temperatures than the 10W-40, therefore it will flow worse on start up; but being a little “thicker” it and maintains its viscosity at high temperatures better than the 10W-40. As few of us ride in the winter, the 15W-50 is a good choice.

Can I mix 10W40 with 15w50?

There is absolutely no harm in mixing different grades of engine oil! All motor oils are required to comply with international standards which include a compatibility test. This means that any branded engine oil will mix with the standard test oil in any proportions and the mixture will still perform as specified.

Can I use 15W40 oil in my petrol car?

Shell Helix HX5 is a conventional (mineral) oil with viscosity 15W40 meant for gasoline and diesel engines. So 15W40 CAN be a choice of oil for a gasoline engine if the manufacturer recommends or allows it.
