What happens if you put thicker engine oil in your car

Thick Oil In Engine. What Is The Thickest Motor Oil Made Thicker oil can reduce fuel efficiency, resulting in higher costs at the gas pump 5W-30 oil can operate in temperatures as high as 95°F, after which you should switch to a better high temperature oil viscosity grade

Higher numbers mean thicker oil consistency at engine operating temperatures The cons of using a higher viscosity oil in your older engine • Poorer circulation— A higher viscosity oil has more internal friction, resulting in slower flow

Thickest Engine Oil

Using the wrong oil type can lead to engine deposits and sludge buildup, which can cause engine damage over time Which engine oil type is best? The optimal engine oil type depends on your vehicle's specifications and driving conditions: Conventional Oil: Suitable for older engines with simple designs Synthetic Oil: Offers superior performance, better fuel efficiency, and longer intervals between oil changes.

Oil Sludge in the 1.8L Turbo Engine. A thicker oil, because it doesn't flow as well, can't remove heat as well as the recommended weight oil. Overfilling the engine with thicker oil can cause oil foaming, which can lead to oil starvation and engine failure.

Thicker Oil For Older Engines Alert Data. Thicker oil maintains a consistent film between moving parts, reducing metal-to-metal contact and contributing to longer engine life For example, 10W-30 flows well in cold weather from the 10W rating, but thickens up at higher engine temperatures from the 30 rating.
