Five gallons of paint is heavier than five gallons of water, which is heavier than five gallons of oil, so please be more specific.
5w30 oil is thinner in cold weather at 5 weight, and is 30 weight at full operating temperatures. 10w40 is heavier in cold weather at 10 weight and heavier at full operating temperatures at 40 weight.
5 cups of water is heavier than 1 Kg.
yes. 5 pounds is much heavier than .1 or 1/10 pound.
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.
Possibly. Excess oil increases oil pressure and can put an extra strain on gaskets. This is especially the case when "heavier" oil is used (i.e. 15/40) rather than say 5/30 or 0/30. Consistently overfilling your oil will eventually lead to leaks as the system is designed to operate under certain pressures and by overfilling you are exceeding that.Obviously, older cars or cars that are driven in extreme conditions will be more susceptible. What is generally considered "overfilling?" Anything more than 1/4 of a quart is a good rule to go by.
5w30
Five pounds is heavier than 5 grams.
If the enigine calls for 5w-30 then the only real reason that you switch to a thicker viscosity is to lessen oil leaks? If yes, than there is nothing wrong with that.
Newer engines are machined to tighter specifications than older motors. Newer motors require a lighter grade oil for lubrication like a 5 or 10 weight. The 5 or 10 weight can move through the engine and get to the places that need lubrication better than a heavier grade of oil. A 10-40 grade moves through the engine like a 10 weight oil with the ptotection of a 40 weight oil. If you put a 30 weight oil in your engine, it will not move through your engine as easily and when it does get to the parts that need lubrication, it does not do as good of a job.
no 5 kg = 11.02 lb
no they are the sane
