Is Thicker oil better for turbo engines?

Thick oil is also ineffective at properly lubricating moving parts, which can cause problems in the turbo system.

Do turbo engines need thicker oil?

Because turbos spin hundreds of thousands of revolutions and they need really good lubrication. They need a little heavier oil.

What is the best oil to use in a turbo?

Mobil 1 motor oil provides our best performance and protection from the punishing operating conditions of turbocharged engines.

Is Thicker oil better for high performance engines?

But really, thicker oil is not good for your engine. Not when “thicker” means higher viscosity than the manufacturer recommends. Your engine was built to specific tolerances – spaces between the moving parts. So the recommendation for a specific grade of oil is deliberate.

Will thicker oil damage my engine?

Not only that, but the engine will waste energy pumping the thicker oil, reducing fuel economy. Since thicker oil doesn't transfer heat as well as thinner oil, operating temperatures will increase, possibly leading to accelerated chemical break down (called “oxidation“) and harmful sludge and deposits.

Will Thinner Oils Damage Your Engine?

Should I switch to thicker oil?

The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well. As long as you're not hearing knocking or serious mechanical noises from the engine, the heavier oil should buy you many more miles of service from your vehicle.

Is thinner or thicker oil better?

Engine oil viscosity

Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.

Why do race cars use heavy oil?

That being the case, they compete with each other for space, so to speak, like pigs competing for room at the trough. Racing oils are often formulated with a heavy dose of friction modifiers to add lubricity for maximum horsepower and torque.

Why do race engines use thicker oil?

Why Do Race Engines Use Thicker Oil? In most racing engines, the clearances are loose, rather than the basic street engine, and most racing engines are run in warm, Summer weather, which would require thicker oil to protect the engine. A thick oil is thicker when it is cold and thinner when it is hot.

Will 10w40 hurt a 5w30 engine?

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.

Is synthetic oil better for turbos?

"With its superior resistance to deterioration, AAA's findings indicate that synthetic oil is particularly beneficial to newer vehicles with turbocharged engines and for vehicles that frequently drive in stop-and-go traffic, tow heavy loads or operate in extreme hot or cold conditions."

How do I prolong my turbo life?

Do turbo engines need special oil?

For the best performance from a turbocharger, change the oil at least every 5,000 miles, replacing it with a fully-synthetic oil which is the right API for your car's engine type. Your vehicle's handbook should recommend the best choice of oil for your car.

What oil is better for racing?

What is the best oil to use in racing engines? Professional racers across North America recognize AMSOIL products as the best and most effective available. The number of championships and checkered flags claimed by AMSOIL sponsored racers is testament to the extraordinary performance AMSOIL products provide.

What oil do v8 Supercars use?

“Castrol has been a great supporter of Supercars as our Official Oil supplier, and naming rights partner of the Castrol EDGE Townsville 400 and Castrol Gold Coast 600," Braid said.

What oil do Nascar drivers use?

Mobil 1™ is the Official Motor Oil of NASCAR® ExxonMobil and NASCAR have a long-standing partnership, with the Mobil 1™ brand serving as the Official Motor Oil of NASCAR since 2003.

What weight oil do NASCAR engines use?

What Weight Oil Do Nascar Engines Use? The NASCAR Engine Oil Viscosity NHRA Pro Stock is 0W-5. The NASCAR Sprint Cup is 10W-30. The World of Outlaws – 15-50.

Does high performance oil make a difference?

With one high-performance car test with a leading synthetic oil, torque improved by less than 1 per cent and horsepower was up around 1.5 per cent. Fuel efficiency gains were better – up nearly 1 mile per gallon.

What grade of oil do f1 cars use?

The most common type of race oil is a 10W-60 viscosity grade based on a Group IV full-synthetic PAO base oil blend. However, there are many base oil mixtures possible.

Why do new engines use thinner oil?

To prevent fuel consumption due to excessive fluid friction, automobile manufacturers (OEMs) strive to use even thinner engine oils.

When should I use 20w50 oil?

20W-50 is only used for certain older vehicles or worn engines that require the extra cushioning of a high viscosity oil. Other than that, it really isn't a high mileage oil. This is because 20W-50 is a thicker oil, and the added resistance can cause further engine wear and damage to both newer and older vehicles.

Is Thicker oil better for older cars?

Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss.

Is 5w30 better than 10w40?

The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.

Is 10w30 thicker than 5w30?

So both the oils 5W–30 and 10W–30 have exactly the same viscosity (SAE 30) when your engine is running, and will perform in the same way. However, the 10W–30 oil will be thicker (higher viscosity) than the 5W–30 when it is cool.
