What oil is best for old engines?
synthetic oilsFull synthetic oils are always a good choice for older vehicles that have been used a lot.
They are perfect for lubricating motor parts as they do it much better than any other oil..
What happens if I put 10w40 instead of 5w30?
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. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
Does thicker oil increase oil pressure?
Yes thicker oils will increase oil pressure, but will reduce engine horsepower. Excessive oil pressure may explode the oil filter, damage seals, blow out oil passage plugs or even damage bearings.
Which oil is thicker 5w30 or 10w40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
Which motor oil is thicker 5w30 or 10w30?
10w30 is thicker then 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil.
Can the wrong oil mess up your engine?
The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.
What oil do Nascar engines use?
Mobil 1Custom racing engines need to endure high rpm and operating temperatures, so they require specially formulated, advanced motor oils. It’s a big reason why Mobil 1 is the Official Motor Oil of NASCAR and half of all NASCAR teams use Mobil 1 motor oils for proven performance in the most extreme conditions.
What happens if I use 0w20 instead of 5w30?
0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. 0w-20 may be a recommended oil for certain conditions for your engine and may not be recommended for your engine.
Should I use different oil in the winter?
The lower the W number, the better the oil will perform in colder temperatures. Typically, a 5W oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold.
Can I use 5w30 instead of 10w30?
Yes. 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature. The 5w30 is better because it thickens less when cool or cold. 80% of wear occurs at start up.
Is Thicker oil better for high mileage cars?
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.
What happens if I put wrong oil in 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 10w30 better for high mileage?
Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.
What is the best oil for winter?
A lower number is better before the W for cold-weather performance, so 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.
What happens if you put thicker oil in your car?
#4 – Poor Fuel Economy If you use too thick of a motor oil for the conditions, your fuel mileage will likely suffer. This is because the thicker oil increases resistance on moving parts such as pistons. While your engine will be protected, it will be at the expense of more frequent trips to the gas station.
Should I use synthetic oil in my high mileage car?
High mileage oil is designed for vehicles with more than 75,000 miles. … This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it’s suggested that you go with this type of synthetic oil. Not every car requires synthetic or high mileage oil.
Is 5w30 or 10w30 better for winter?
At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.
Should I 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.
What’s the best motor oil for high mileage?

When should I use 5w30 oil?
The lower viscosity of 5W30 will be perfect for use in cold weather as the oil is thin enough to get into different parts of the engine even in cold weather and to ensure easy startups. The thinner nature of this oil will ensure your vehicle maintains optimal performance in winter.
Should I use thicker oil in winter?
Thin oils that are less prone to thickening in low temperatures will help you start your engine more quickly in winter while thick oils that are less prone to thinning in hot temperatures will help your engine perform better in summer.
