What is the difference between 10 30 and 5w 30 oil

This form of oil is most commonly used in heavier and larger engines that have to haul large loads across places, and rightfully so. I've loved cars since I got my first car, an old Ford Escort when I was sixteen. I'm always looking for the next big thing in the industry, and I'm always happy to share it with others with product guides, reviews, and useful tips.

Ken Scales Auto advises Oregon residents to change install 5W motor oil before the first freeze, especially for folks who live in the eastern part of the state. In years past, owners of high mileage vehicles would use a higher viscosity oil than what was recommended by the manufacturer, say 15w40 instead of 5w As the oil passages wore down with age, switching to a thicker oil would increase the oil pressure, which would hopefully be enough to push it through every space in the block and heads to keep them lubricated.

That means switching to a higher viscosity oil can do more harm than good, putting more strain on the oil pump and preventing it from pumping it everywhere it needs to go. These oils address these issues with added conditioners that can help restore internal seals. In this test, the viscosity determined by the number of seconds it takes for the oil to flow through a specific size tube. All fluids thin as they warm up and thicken as they cool.

For example, a 10w30 oil takes 30 seconds to flow through the tube when cold, and 10 seconds when hot.
