What is the best 20W50 Motorcycle Oil?

Here are our top recommended the best oil for Harley Davidson V-Twin Cam:

  • Best Overall: AMSOIL FULL SYNTHETIC Motorcycle Oil 20W-50.
  • Runner-Up: Mobil 1 -50 V-Twin Synthetic Motorcycle Motor Oil.
  • Best Budget: Castrol 06116 POWER1 V-TWIN 4T 20W-50.

What is the difference between 20W50 and SAE 50?

20W50 is a base oil of SAE 20W and the viscosity grade at running temperature is SAE 50. However, these VI Improver additives are susceptible to shearing damage from the mechanical components and would lose some of their performance, resulting in 20W50 oil acting more like 15W40 oil.

What is 20W-50 used for?

SAE 20W50 Synthetic Motor Oil. NEO SAE 20w-50 is designed for high performance engines of all kinds, and for any engine that is pushed to the limit of performance and temperature. Excellent for trailer towing in high temperatures and for racing engines, in any engine that can use this viscosity grade.

Is 20w50 good for high mileage?

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.

Is 20w50 oil bad for my car?

Use in Cars A 20W-50 oil will not protect a car as well in a cold winter and its greater viscosity will increase drag and friction in a passenger vehicle.

Can I mix 20w50 with 5w30?

Yes, you can. It is best if they are from the same brand and level of API service to be the same formulas, but they are certainly compatible, even if different formulas and brands. I once needed oil on a trip, and my car had 5W-20n ILSAC approved oil in it as recommended by the factory.

Can I use 5w30 instead of 20w50?

20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate. Trust the engineers that made your vehicle.

Can I mix 20w50 with 10W30?

No, you’ll be fine. I swear I didn’t know. If you mix viscosity grades such as a 10W30 low-viscosity oil and a 20W50 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 10W30, but thinner than the 20W50.

Is high mileage oil thicker?

High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives. Typically they use a viscosity modifier that is durable and won’t lose viscosity very easily. These oils need to stay thicker longer to protect engine parts.

Will a bad lifter hurt your engine?

The malfunctioning lifter will cause the pushrod to bend and fall out of space. When that happens, it leads to a dead cylinder that might break valves, rocker arms, or even damage the entire engine.

How bad is a lifter tick?

In general, the lifter tick will not stop your car from running. Many people do not even pay attention to the ticking sound. It is recommended that you do not ignore any weird sounds in your vehicle as they might cause severe damages in the long run. Unfortunately, engine ticking sound requires maintenance.

What causes cam and lifters to go bad?

Valve lifters are one of the first components to suffer wear when the oil pressure is consistently low. Low oil pressure can result from a number of factors, including excessive camshaft end play and worn cam bearings, worn oil pump gears, worn crankshaft journals and bearings and worn main and rod bearings.

What causes a cam to go bad?

A broken camshaft is usually caused by a connecting rod or other rotating part coming loose and striking it. Sometimes the cam will break after a short time of use because of a crack or fracture in the cam due to rough handling during shipping or improper handling prior to installation.

What problems can a bad lifter cause?

A faulty hydraulic lifter will usually result in the rocker arm, valve tip and push rod also going bad if left unattended. You need to know how to tell when they hydraulic lifter is going bad or needs to be replaced. The most obvious symptom of a faulty hydraulic lifter is the noise it creates in your car’s engine.

Can bad valve lifters cause misfire?

If the lifter is not holding oil pressure and always bleeding out because of a malfunction internally, the valve will not open fully, resulting in a misfire. As far as bad compression is concerned, bad lifters could possibly be the cause as a delayed valve opening/closing function could cause poor combustion sealing.
