Whats the difference between 20W50 and 10W40?

10W40 oil has a 40th viscosity grade, while 20W50 has a 50th viscosity grade. This means 10W40 is more viscous than 20W50 at low temperatures making it best for winter vehicles. On the other hand, 20W50 is best for use in hotter climates. Keep in mind to stick to the prescribed viscosity grade by the manufacturer.

Is Thicker oil better for older engines?

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.

What oil is the thickest?

Importance of a Viscosity Scale

In order to have a standard way to measure the viscosity of engine oil, the Society of Automotive Engineers (SAE) developed a viscosity scale. The scale ranges from 0W, which is the thinnest type of oil, to a rating of 60, which is the thickest oil.

Which car oil is thicker?

SAE50 is higher viscosity (thicker) than SAE40, and so on. Straight-weight oils come in a wide range of viscosities. But your car operates (ostensibly) in a wide range of temperatures. When your engine is running at operating temperature, it does not matter too much if it is summer or winter.

Which is better 10W30 or 20w50?

It really comes down to personal preference. As your engine does put out significant horsepower, we would lean toward using 20W-50. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.

Can I use 20W 40 instead of 10W40?

Using 20W-40 oil instead of 10W-40 will cause a little more engine wear and harder starting in cold weather, just as in a car. BUT, it will also take longer to spin off the clutch plates, causing more slippage. But more importantly, no matter what viscosity you use, make sure it has JASO MA2 spec on the label.

What happens if you put too thick oil in a car?

If the oil is too thick (aka, the viscosity is high), your car may not start in cold temperatures (cold weather places more strain on a vehicle in any case). When this happens, the thick liquid can't properly lubricate every part, and it creates enough resistance to impair the most important function–ignition.
