A registered user. The Ranger said that you can mix 10W &
30W to get 20W, or you can mix 5W20 &
10W40, but you don’t want to mix 10W &
30W. The answer is yes, but not straight weights or multigrades.
What happens if you put 10W-40 instead of 5W 40?
Can I Use 10w40 Instead Of 5w40? The synthetic engine will be fine as long as it is fully synthetic. 5W – 40 is better for colder conditions, 10W is thicker to start, so it does not get to places around the engine as quickly as 5W-40, but it all depends on the temperature.
Is 10W-40 better than 5W-30?
5w30 oil is especially well suited to vehicles operating in cold climates. 5W-30 motor oil is mainly of cold-weather viscosity quality.Comparison Table Between 5w30 and 10w40.
|Parameters of Comparison||5w30||10w40|
|Thickness||5w30 oil is thinner than 10w40 oil.||10w40 oil is thicker than 5w30 oil.|
Can I use 10W-40 instead of 5w30?
Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
Can you mix 10W40 and 5w20?
The answer is yes, but not straight weights or multigrades.
What temperature is 10W40 good for?
However, 10W-40 engine oil is more viscous in hotter climates and has a better temperature spectrum. Here’s the recommended ambient temperature range for each oil grade, in general: SAE 10W-30 motor oil: -25°C (-13°F) to 30°C (86°F) SAE 10W-40 motor oil: -25°C (-13°F) to 40°C (104°F)
Is 10W40 good for high mileage?
Is 10w40 Good For High Mileage? The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.
What car is 10W40 oil for?
This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.
When should I use 5w 40?
5w40 is better for starting your engine at low temperatures as it flows more easily in this environment. When the engine is running and hot, the differences are negligible
5w40 and 10w40 both have high viscosities and are equally effective in protecting against engine wear.
Does 10w40 hurt 10W30 engine?
If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.
Is 10w40 better for older cars?
Is 10w40 Better For Older Cars? When you put more pressure on your vehicle’s engine at high temperatures, 10w40 will reduce wear and tear on the engine and make it more durable. 10w40 is also an excellent choice for older vehicles.
Can I put 10w40 instead of 10W30?
Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.
Can you put 10w30 in a 5w20 engine?
Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.
Can I use 5w20 instead of 5W-30?
Mixing 5W-20 and 5W-30 (or any other oils for that matter) may lead to faster wear and tear of your engine and eventually cause problems with the basic functioning of critical engine parts. And even if your engine allows it, you won’t get any noticeable results by mixing different viscosity grade oils.
What oil is thicker than 5w20?
However, 5W-30 features a slightly higher viscosity at 100 degrees Celsius than does 5W-20. This means that once the engine reaches normal operating temperature, 5W-30 oil will be thicker than 5W-20.
Will the wrong oil damage my engine?
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 Thicker oil better for older engines?
Older engines use more oil, but it gives them a better fuel economy. Older engines with more than 75,000 miles on them require a thicker oil that will lubricate their critical engine parts and prevent oil leaks, sludge, and deposits from forming.
Should I use thicker oil in a high mileage engine?
High mileage engines will need thicker oils. Thicker oils have additives such as conditioners, antioxidants, seal swells, detergents and friction additives that are engineered to take care of high-mileage engines. Gaskets, seals, and non-metal parts start decaying as an engine ages.
Can I use 10W40 in my generator?
Can I Use 10w40 On A Honda Generator? If you are using a generator, you just want to make sure the oil is the right weight. If you are using a generator that requires 5W-30 oil, you should not use 10W-40 oil for your vehicle.
Which oil is better 5W-30 or 10W 30?
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.
What is difference between 5W-30 and 5W 40?
5w40 oil is not thicker has it has a higher viscosity. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures. 5w40 has higher viscosity hence it is not suitable at all temperatures. 5w30 is a multi-graded oil which is suitable to use in lower temperature.
Which engine oil is good for old engine?
Which oil is best for old engines? It is the Valvoline MaxLife 10W-40 oil that stands out as the best for motors that are old. The additives in Valvoline are enhanced. Your motor will perform better when you use the additives.
What does 10W40 oil 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.
What weight oil is best for high mileage?
The Bottom Line
Some people need an SAE 5W20 high mileage oil, while others prefer 5W30 or 10W40. Whatever your needs, consider using high mileage oil in your car today if it has more than 75,000 miles on it.
Is 10W-40 fully synthetic?
Semi-synthetic oils such as 10W40 have long been the standard. Their base is refined crude oil, which is then blended with additives. However the market is moving towards synthetic oils.
Is 10W-40 oil fully synthetic?
CASTROL 10W-40 PRODUCT RANGE

Can 10W40 be used in diesel engine?
Can I Use 10w40 Oil In A Diesel? Synthetic motor oil with 10W-40 strength from Premium Protection. Both gasoline and diesel engines can be used with this product. This product is ideal for applications where a higher-viscosity oil is desired to be protected.
Is 5W 40 oil good for hot weather?
5W40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5W40 and 10W40 have high viscosities and are equally effective in protecting against engine wear.
Is 5W 40 fully synthetic?
Full synthetic 5W-40 motor oil is formulated to flow like 5 Weight oil from a cold start in winter temperatures and like 40 Weight oil once the engine has reached its normal operating temperature. Castrol® EDGE® is an advanced full synthetic 5W-40 motor oil.
Is 5W40 better than 10W40?
5W40 vs 10W40 – Differences
The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). If your motorcycle requires a 10W40 engine oil, there is no need to go for 5W40 oil.
