Top Myths About Engine Oil
                     Top Myths About Engine Oil
  
When it comes to your car’s maintenance and preservation, 
motor oil is perhaps the utmost responsibility. Oil is what 
allows the various parts of your engine to seamlessly and 
smoothly interact with as little friction as possible, leading to 
reduced wear, lower temperatures, and a nearly eradicated 
chance of seizing.  
However, when it comes to oil, there’s a number of different 
myths and misconceptions that have either invaded general 
knowledge, or used to be true but no longer are. However 
they may have gotten there, it’s time to set the record 
straight. Here are eight of the most popular motor oil myths, 
and the truth about each of them
  
Dark Oil Always Needs to Be 
Changed
False. Dark color is not a strong indication that your oil is 
dirty or no longer doing its job. In fact, some oils go dark 
quickly as the additives designed to clean your engine 
start working. However, gritty or grainy oil is dirty and 
needs to be changed ASAP.
  
You Have to Get Your Oil 
Changed Every 3,000 Miles
While the 3,000 miles is a good rule of thumb, this is not 
always true. Some cars using good-quality oil can go as much 
as 8,000 to 10,000 miles or more between oil changes. The 
best way to find out how often you should change yours: refer 
to your owner’s manual.
  
Synthetic Oils Equal Higher 
Mileage
Not necessarily true. There are other reasons synthetic oils 
seem to last longer than their petroleum-based counterparts. 
For instance, they work at very high temperatures, provide 
better protection against wear, give greater stability to the 
engine, and encourage the formation of fewer deposits.
  
Taking Too Long Before an Oil 
Change Voids Your Warranty
In this day and age when synthetic oil with extended life is in 
use, that’s probably untrue. Even if your vehicle manual 
expressly instructs you to use petroleum-based oils, your 
warranty will not be voided unless there’s a demonstration that 
the oil was the immediate cause of the problem.
  
More Oil Is Always Better
The worst mistake you can make is to overfill your engine oil 
just because it leaks. When in excess, engine oil causes 
expanded obstruction which leads to excessive heat. The extra 
oil could also end up in the cylinders leading to excessive 
burning, which in turn leads to increased deposits in the 
combustion chamber. The proper remedy is to fix the oil leak 
problem or top up the engine oil daily.
