5w30 oil is particularly well suited for cars driven in cold climates. Unlike oils with a higher hot temperature rating such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine's internal components.
This means you can mix any SAE graded motor oils. You might see SAE 30 oil specified for an older engine, like those in classic cars. However, modern engines typically require multi-grade oils, so using an SAE 30 motor oil in any vehicle built recently would be inadvisable.
Basically, SAE 30 and 5w30 have the same rating or viscosity of 30 while hot, but when cold their ratings differ. Because of this, they have slightly different uses: SAE 30 is the most common small engine oil, and 5w30 is used mostly in the automotive industry.
The 5W30 has a viscosity grade of 5 at low temperatures and a grade of 30 at higher temperatures. The 5w30 car engine oil is typically used in light-duty petrol and diesel engines. You will find that most automobile manufacturers recommend it for cars and SUVs.
Using 5W-30 instead of 5W-20, you risk damaging your car's engine because the internal engine components work with 5W-20 motor oil. 5W-20 and 5W-30 motor oil both have the same winter rating. It means that both motor oils have the same viscosity under cold temperature.
If you put in 5W-30 oil instead of 5W-20 when the latter is the grade suggested by your vehicle's manufacturer, damage to internal engine parts can occur. Additionally, your engine may experience performance issues such as diminished fuel economy and horsepower.
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Is 5w30 Good For Hot Weather? In warm climates, such as those that reach 35 degrees Celsius or 95 degrees Fahrenheit, 5w30 is also a great choice. It is generally considered to be a great multigrade oil that can meet the demands of almost any temperature in both warm and cold climates.
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.
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.
SAE 30 oil is typically used for smaller air-cooled engines, like the ones in small tractors, lawnmowers, and chain saws. Most motor oils today are multi-grade oils that will perform well in all seasons.
An SAE oil is a motor oil that complies with the SAE standard. What's that? Motor oils are classified by viscosity, using a rating system developed by the SAE (Society of Automotive Engineers). The letters “SAE” should precede the oil viscosity on the motor oil labeling.
Unopened Motor Oil
Motor oil stays good in the oil bottle until its expiry date when unopened. This will give you about 2-5 years before unused oil becomes unfit for consumption.
Air cooled motors should use SAE 30 during the summer months, I generally start using SAE 30 in my garden tractor May 1st give or take a month (depending when it has 25 hours on the oil) Spring and fall I use SAE20 when the temps are above 32 and winter 10W30 temps below 32.
A full synthetic motor oil.
It is recommended by most car owner's manuals that the oil be changed every 5,000 or 7,500 miles, rather than every 10,000 miles.
Mobil 1™ 5W-30 is an advanced full synthetic motor oil designed to keep your engine running like new by providing exceptional wear protection, cleaning power and overall performance. Mobil 1 5W-30 meets or exceeds the requirements of the industry's toughest standards and outperforms our conventional oils.
5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.
Is 5w30 Or 5w40 Better For Summer? The 5W30 can be used by a variety of vehicles, in different temperatures, and in different climates. However, it is best suited for colder temperatures when used in a vehicle. The higher mileage engine sand used in 5w40 is often better at withstanding warmer temperatures than 4w40.
The most important thing is to use oil that's the right thickness, or viscosity, for your car's engine. Oil that's too thick or thin won't provide the necessary protection for your engine, which can result in costly damage.
When it comes to doing oil changes, switching between synthetic and conventional oil is perfectly okay. Despite the oil myths, both oil types are compatible with each other – no engine flush needed. So, simply making the switch will not cause any damage to your engine nor impact your travels.
Using the wrong oil type and viscosity in your car's engine can cause it to smoke excessively. It's due to the oil not burning correctly, causing it to get into the exhaust. This results in your exhaust blowing white smoke.
Yes, you can mix 5W20 and 5W30 oil. However, your engine MUST support it. Both oils should be of the same brand to prevent engine damage and should also be of a similar API service level.
regular oil and advising whether mixing motor oil is okay. So, can you mix synthetic oil with regular oil? Yes. If it's something you do only occasionally, mixing shouldn't damage your engine.
