Can I use 5w30 instead of 10w40?
The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.Can I use 5W 30 instead of 10W?
According to API motor oil guide [1], If you are using 10W–30, you can safely switch to 5W–30 (in car engines). 5W–30 is thinner than 10W–30 when cold. (you must follow the manufacturer's recommendations). However, switching from 5W–30 to economical 10W–30 is not always recommended.What happens if I use 5w30 instead of 10w30?
Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digit 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate. 5w30 is much suitable during the cold season.What replaces 10w40?
10W30 and 10w40 are very similar oils. Both oils are flexible, multigrade oils that perform well in different temperature ranges.Is 5w30 better than 10w40?
The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.Speed test | 5w30 vs 10w40
Is 5W better than 10W?
A quick lesson in motor oil states that a regular engine needs oil that flows under the prevailing weather or running conditions. A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W.When should I use 5W-30 oil?
5W-30 oil is primarily a winter viscosity grade motor oil. While it does perform adequately at a higher temperature, its best use is for people who drive in cold temperature regions. Due to its lower viscosity, it's typically recommended for petrol vehicles or a light-duty diesel engine.What happens if you put the wrong oil in your car?
You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn't working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.Is 5w30 good for summer?
5w30's viscosity range means it can lubricate, seal, and protect an engine's internal components in a range of climate conditions. This ability to function well both in summer and winter brings with it the convenience of not having to change oil weights with the seasons.What's the difference between 5 30 and 5W 40 oil?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.What is 10W 40 oil used for?
Higher viscosity oil such as a 10W-40 can be useful for older engines burning or leaking oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles with more than 75,000 miles, and a synthetic blend oil when cost is a consideration.Will thicker oil damage my engine?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.Is it OK to top up engine oil with different brand?
You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car's manual are your reference for using the right oil.Is it OK to mix engine oil?
Yes. If it's something you do only occasionally, mixing shouldn't damage your engine. Let's say you want to top off your oil, just to keep you rolling until your next regularly scheduled maintenance check. Mixing is alright, if the oil you use is the weight (or viscosity) recommended in your owner's manual.Why is 5w30 oil so popular?
Why is 5w30 oil so common? 5w30 oil is one of the most commonly used motor oils because it is suitable for a wide variety of vehicles and engine types. 5w30's viscosity range means it can lubricate, seal, and protect an engine's internal components in a range of climate conditions.How long does 5W-30 oil last?
Mobil 1™ Extended Performance High Mileage 5W-30Provides 20,000 miles of protection for vehicles with more than 75,000 miles – guaranteed.
Is 5w30 oil good for winter?
The Bottom Line. A multi-viscosity 5W30 oil flows quicker in cold weather and is recommended for year-round protection, and a synthetic 5W30 multi-viscosity will provide the best protection you can get in both extremely cold weather and extremely hot engine temperatures.What cars can use 5w30 oil?
The '30' or '40' refers to the oil flow at higher engine temperatures. '30' is often for newer petrol engines, while '40' is often for older or diesel engines. 5W-30 and 5W-40 oils are compatible with some models of common cars, like the Ford Focus, Ford Ka, Honda Civic and VW Golf.Is 10w40 good for high mileage?
Designed for high mileage vehiclesMobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars. Trucks.
What does 5w30 stand for?
Example 5W30: The W stands for winter, whereby 5W is the low temperature viscosity and 30 is the high temperature viscosity at 100 degrees Celsius. The lower the number before the W, the better the oil will flow at low temperatures.Is 10W-40 too thick?
Bear in mind that mixing motor oils may affect your vehicle's warranty and fuel consumption. Although both 10W-30 and 10W-40 lubricants function the same during cold startups, one is slightly thicker than the other and would be less practical for certain high ambient temperatures.Can I mix 5w40 and 10w40?
If you have drained the engine oil and plan on replacing it with the 5W-40, the small remainder of the 10W-40 will mix in with this new oil.Should you use thicker oil in an older 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.Is 5W30 better for older cars?
5W-20 and 5W30 motor oil are winter viscosity grade oils primarily recommended for older engines and light-duty use. These oils are best utilized in colder temperatures.
