What type of engine oil should I use?
Joseph Russell general
A 5W oil is typically what's recommended for winter use. However, synthetic oils can be formulated to flow even more easily when cold, so they are able to pass tests that meet the 0W rating. Once the engine is running, the oil heats up.

Just so, can I use 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.
One may also ask, can I use 10w30 instead of 5w30? The 10W30 and 5W30 both have different thicknesses in cold temperatures, and 10W30 is thicker than 5w30. So, it is best for vehicles running in cold climates to use the 5W30 since it is thinner than the 10w30. Low numbers indicate lower viscosity, meaning the oils are thinner.
Also question is, is synthetic oil better for your engine?
Because synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles. Synthetic oil change intervals range 10,000-15,000 miles or once a year (whatever comes first).
Which oil is thicker 5w30 or 5w40?
The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.

What's the difference between 5w30 and 5w40 engine oil?
In fact, the only major difference between ?5w30 and 5w40 is the viscosity in warmer temperatures. ?This makes the 5w30 better suited for colder temperatures and the 5w40 better suited for warmer ones.What oil is thicker 5w30 or 10w40?
5w30 is less viscous while 10w40 is more viscous. The 5w30 has a viscosity of 30 at high temperature while a 10w40 has a 40 viscosity at high temperatures. When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40.What happens if I mix engine oil?
Mixing Motor OilAccording to Mobil Oil, it should be fine to mix oils. This manufacturer states it would be unlikely anything bad would happen, such as a gel-forming from an interaction of the chemicals (a common fear), because the oils are compatible with each other.Can I mix engine oil viscosity?
It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. Be aware that mixing viscosity grades will turn out a product that is different in viscosity than either what was originally in the engine or what was added."What does 5w40 mean in engine oil?
In your case, 5W40 means that the oil behaves like a 5 weight oil at low temperatures so it flows easily. At higher temperatures, it behaves like a 40 weight oil, staying more viscous and so providing more protection.Can you get sludge with synthetic oil?
Synthetic motor oil will not thicken during cold temperatures which will make engine starting and oil pressure buildup better. Synthetic motor oil does not evaporate as quickly. At this high temperature oxidation can occur which will develop deposits and varnish. These also can cause sludge.Can you mix 5w30 and 10w40 oil?
As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40.Can I mix synthetic and regular oil?
The simple answer: Yes. There is no danger mixing synthetic and conventional motor oil; however, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits. So, yes, you can safely mix synthetic and conventional oil.How long is synthetic oil good for?
“If you're using full synthetic oil, we recommend going about 7,500 between changes,” says Leo Jay of Dere Auto in Seattle. Bell says that with synthetic oil and some manufacturers, intervals between oil changes can be much, much longer: "In some cases as much as 15,000 miles or one year."How long can synthetic oil sit in an engine?
six months
