What’s the best oil to use in a high mileage vehicle?
Many people ask, “What is the best oil for high mileage engines?” Most people agree that the Mobil 1 Full Synthetic High Mileage oil is the best on the market. It provides superior protection for your engine components, and it will last at least 10,000 miles between changes.
What kind of oil should I use for 100 000 miles?
Older, high-mileage passenger cars should be serviced with a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles to prevent engine damage.
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.
Do high mileage oils make a difference?
Reduced oil consumption: High mileage vehicles tend to leak and burn off more oil than younger cars due to degraded engine seals. High mileage oil rejuvenates degraded seals, which leads to less oil consumption and burnoff. Less engine sludge: Older engines tend to accumulate sludge left behind by other motor oils.
Is full synthetic oil good for high mileage cars?
Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.
Is 10w40 good for high mileage?
Mobil 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.
Which is better high mileage oil or synthetic?
So which one is better? The short answer is full synthetic is always better, but cost is the main reason why I buy high mileage oil vs synthetic oil. If you have over 75,000 miles on your modern car or truck, consider switching to a high-mileage motor oil.
What 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.
Can I switch to synthetic oil after 100k miles?
Yes, you certainly can. Just use the right viscosity oil, or a better range multigrade. If your car was recommended for 10W-30, you can use 5W-30 or 0W-30 for better lubrication in cold climates.
What brand of engine oil is best?
Editor’s Pick: Castrol GTX Motor Oil. Valvoline Daily Protection Motor Oil. Quaker State Advanced Durability Motor Oil. AmazonBasics Motor Oil. Havoline Motor Oil. Pennzoil Motor Oil. Lucas Oil Hot Rod & Classic Motor Oil. Formula Shell Motor Oil.
Is Valvoline good oil?
Valvoline is known to provide top-notch car care products. This particular synthetic oil is very efficient and comes at an attractive price. It’s able to enhance the overall engine performance right after the application, making your vehicle smooth and quiet.
Which oil is better 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 is more suitable for commercial vehicles and other cars with heavy load engines.
Is Valvoline better than Mobil 1?
Multiple tests run concluded that Valvoline SynPower was four times better than Mobil 1 in terms of wear protection when measured in 5W-30 grade tests.
Can you go back to regular oil after using high mileage oil?
Yes, you can. the small amount of seal swell has cleaned up the seals and some carbon or sludge there might have been. If you want to switch to normal synthetic there is no reason not to. Synthetics are no more prone to leakage than mineral oils, contrary to old wives tales.
Is high mileage oil thicker?
High mileage oils contain viscosity modifiers that are durable and won’t diminish over time. This causes the oil to stay thicker for longer periods of time, helping protect your engine parts.
Is synthetic oil good for older engines?
It protects better, performs better, and lasts longer, and it’s no longer made with a chemical compound that could hurt older vehicles.
What are the disadvantages of synthetic oil?
Advantages and Disadvantages of Synthetic Oil Advantages Disadvantages Resistant to oxidation and chemical degradation More expensive Withstands temperature extremes better (cold and hot) Possible additive precipitation/separation Flows better at cold temperatures Slightly lower fuel economy at highway speed.
Which synthetic oil is best?
List of the Best Synthetic Motor Oils Mobil 1 Extended Performance Synthetic Motor Oil. This is our top pick for numerous reasons. Royal Purple High-Performance Synthetic Motor Oil.

What happens if I put 10W40 instead of 10W30?
10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.
Which is better 10W40 or 20w40?
A 10 W 40 oil will have the viscosity of a 10 Grade oil when cold and that of a 40 Grade oil when hot. A 20 W 40 oil can replace a 10 W 40 if your winter / cold temperatures are not too low. A 10W 40 will afford better lubrication and performance over a wider temperature range than a 20W 40 oil.
What is the difference between 5 40 and 10W 40 oil?
5W40 vs 10W40 – Differences The main difference between the two oil types is that one is thinner than the other. 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).
