the weight of oil that is in the motor...10w-30 is more than enough, if the oil was changed and say 20w-50 oil was put in then your oil pressure is going to be higher...the oil is thicker or heavier

The weight of a thread has to do with its size. A 50 weight thread is finer than a heavier 30 weight thread. 30 weight thread is commonly used for top-stitching, while the finer 50 weight thread is used for sewing seams and piecing.The weight of a thread has to do with its size.

The answer to this depends on what kind of oil you are talking about. If you put a heavier weight oil (like 5 weight) in your car instead of say,30 weight, it will cause your car to act sluggish in the cold weather because the oil is thicker. If you put a lighter weight (30 weight ) in a vehicle that needs a heavier oil, the car will still run but not as well as using the correct type of oil. If you put transmission oil in your car's engine oil pan by mistake; you should empty out the oil pan immediately (when the oil and car are cold) and flush it or refill it with the correct oil as soon as you have realized it was the wrong oil.
