Should I use thicker oil in a high mileage engine?
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 10w 40 too thick?
Multi-grade oils could stay as close to the optimum viscosity over a range of temperatures – not too thick when it is cold and not too thin when it is hot. … The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
When should I use 10w40 oil?
When to Use 10w30 vs 10w40 Using 10w30 oil in cold weather will help reduce excessive oil temperatures and drag as the engine warms up. Using 10w40 oil in the summer will help the oil stick to internal components in high temperatures, avoiding the wear and tear from metal-to-metal contact between moving parts.
Can I replace 5w30 with 10w40?
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.
Will thicker oil damage my engine?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
Does 10w40 hurt 10w30 engine?
Changing from 10W30 to 10W40 will not do any effect on your engine if you choose right one for the right season. Engine oil is one of the main part for the engine. The grade given on the bottle of engine oil 10W30 or 10W40 it just indicates the suitable oil for different season.
Is 10w40 good for winter?
Yes, although they are both technically 10w oils, a 10w-40 is much thicker in cold conditions compared to a 10w-30.
Is 10w30 better for high mileage?
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 5w20 good for high mileage?
5w30 or 5w20 for high mileage 5w-20 or 5w-30 oil can work effectively with a high mileage car. The former is more appropriate in cold weather, while the latter is advisable during a warmer temperature.
Can I switch from 10w40 to 5w30?
Yes you can change to total 5w-30 if engine is not reducing oil. It’s one of the best oils in market if you are getting it from total pump directly to avoid fakes.
Will thicker oil stop lifter noise?
If the oil is too thick then it will not pass through the tiny holes resulting in an increase in friction. The increased will not only lead to noisy lifters, but it may also increase the temperature a little bit. On the contrary, if the oil is too thin, it won’t provide proper lubrication as well as padding.
Which oil is best for high mileage engines?
Valvoline High Mileage with MaxLife Technology. … Castrol Edge High Mileage. … Mobil 1 High Mileage. … AmazonBasics High Mileage Motor Oil. … Pennzoil High Mileage Motor Oil. … Lucas Oil High Mileage Oil Stabilizer. … Royal Purple HMX High Mileage Synthetic Motor Oil.
Is 10w40 better than 5w30?
The 5w30 oil will flow better at low temperatures than the 10w40 oil. … At high temperatures, the 5w30 oil is thinner than that of 10w40 since 30 is lower than 40. These numbers, however, do not depict the actual viscosities of the oils at extreme temperatures.
Is 20w50 good for high mileage?
Considerations. The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.
When should I use 20w50 oil?
20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.
