How do I know what oil to put in my car?
There’s no substitute for reading your owner’s manual. It will list what type of oil the automaker recommends for your car. It may also recommend different oil depending on whether you live in a hot or cold climate. The most important thing is to use oil that’s the right thickness, or viscosity, for your car’s engine.
Is it OK to 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.
Is it better to use 5w30 or 10w30?
5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 us more suitable for commercial vehicles and other cars with heavy load engines.
What does 5w30 oil mean?
The short answer:The numbers represent the viscosity of the oil and the W stands for WINTER. In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil’s cold temperature/ cold start performance.
What happens if I put the wrong oil in my car?
Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won’t harm the engine, but there’s also no benefit in doing so.
Can I use 10w40 instead of 5w30?
One must use the oil specified by the manufacturer. If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters.
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.
Is it OK to mix old and new oil?
When you mix new and old oil, the new oil becomes “watered down” with the lack of interfacial tension and strains to do its’ job. Be sure to have your oil changed as soon as possible.
Is there a difference between 5w30 and 5w40?
5w30 is engine oil that has lower viscosity 5 and higher viscosity 30. 5w40 is engine oil that indicates the weight and viscosity of the engine. Its lower viscosity is 5 and higher viscosity is 40. 5w40 oil is not thicker has it has a higher viscosity.
Is 5w30 good for high mileage?
5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. Furthermore, high–mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.
Will 5w30 hurt a 0w20 engine?
No, not true. A 5W-30 full synthetic will flow fine. If you look at the owner’s manual for the same Toyota engines in many other countries, they specify 5W-30 for better engine longevity. The reason why they specify 0W-20 (and new cars are trying to go lower such as 0W-16) is for better gas mileage.
Should I use thicker oil in a high mileage engine?
A: Yes. This is a practical method to improve oil pressure in an older, high–mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.
Which is better 0w20 or 5w30?
0W-20 OIL. It readily means that the 0 oil will flow well and better at a cold temperature more than 5W-30 oils even while maintaining the same viscosity. The 0W-20 is said to be the best oil in the market because it helps to reduce environment hassle on waste oil disposal.
Does it matter what 5w30 oil I use?
If your car takes 5w30 oil and you put 5w30 oil in it, it’ll be fine. Totally wrong, these days the spec compliance of an oil is often more important than the viscosity. Don’t put any 5w30 in, put the correct 5w30 in.
Which is better 5W-20 or 5W-30?
The thicker 5W–30 should see a slight advantage when operating at higher temperatures, while the thinner 5W–20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency.
