The viscosity of an oil is measured by its resistance to flow. Check out engine oil grade descriptions and learn how motor oil viscosity works
What's the deal with thick or thin motor oil? The viscosity of motor oil is indicated by two numbers, for example 5W-30. The first number with the "W" stands for the low-temperature viscosity, i. e. how fluid the oil is at low temperatures. The second number represents the high-...
2. CRACKING THE MOTOR OIL CODE. Let’s say your vehicle owner’s manual recommends 5w30 oil. The W stands for winter and means that this oil is formulated to work well in colder weather. The numbers refer to oil viscosity (or thickness), based on a scale established by the Society of...
MOTOR OIL BY THE NUMBERSLook at the label, and you’ll find most motor oils have two numbers. This means they are multi-grade oils. The numbers refer to oil viscosity (or thickness), based on a scale established by the Society of Automotive Engineers (SAE). ...
After the “W,” there are two other numbers. These indicate the oil viscosity rating when operating at 212 degrees Fahrenheit. Basically, this number shows how fast the oil thins out when operating at higher temperatures. In this example, the 10W-30 motor oil and 10W-40 oil are going to...
Switch to Pennzoil Platinum™ Full Synthetic motor oil and keep pistons up to 30% cleaner and delivers protection in 0W-20, 5W-20, 5W-30, 10W-30 viscosities.
RAVENOL GFE SAE 5W-20is a synthetic, low-friction engine oil with CleanSynto® technology for passenger car gasoline and diesel engines, with and without turbocharging and direct injection. RAVENOL GFE SAE 5W-20achieves a high viscosity index through its formulation with special base oils. ...
Cold temperatures would increase the oil viscosity which should increase the stability of the PTFE suspension. Plugged oil filters are another concern that has been raised by the use of PTFE. The pore (hole) size of most oil filters is about 35 μm. The particle size of suspension-...

oil to break down sooner, leading to performance-robbing deposits, while shearing forces inside the turbo can tear apart the molecular structure of the oil, leading to viscosity loss. Oil that has lost viscosity can fail to provide an adequate fluid film to guard against wear, potentially ...
