FIND OUT WHICH OIL IS BEST FOR YOUR CAR ENGINE


Having a car is like having a family, there are good times, and there are times when we need to take care of things that are often seen in a carefree way. And one of these precautions generates a lot of doubt in the owner's mind, is the choice of engine lubricating oil . View here for more info: royal purple oil vs mobil 1


Many people do not know what oil to use, how much and what its function is, and this lack of knowledge can lead you into situations that could have been avoided. The use of lubricant outside the manufacturer's specification can cause high fuel consumption and premature engine wear, reducing its useful life. Right away, that's it.


The main function of engine oil, of course, is to lubricate the moving parts, avoiding friction between the parts, it also has the ability to exchange heat with the cylinder walls helping the engine's cooling system, in addition to dispersing waste to prevent these wear out the engine.


It is common for people to go to an automotive center, workshop or even a gas station just to change the oil, and when they arrive at the place they are faced with the question, which oil to use? Immediately, several truths and myths arise, created by the mechanics of the establishment, but this time we are going to clarify three important things to choose the correct lubricating oil for your vehicle.


  1. SAE Specification: This is the engine oil viscosity specification, the name of these lubricants is multigrade and their specification is made up of two numbers separated by a W (winter). In an SAE 5W40 oil, the specification states that running cold it behaves like an SAE 5 (very fluid) oil, and at working temperature (hot) it behaves like an SAE 40 (Viscous) oil. Failure to use oil with the correct SAE specification can cause excessive oil consumption or high fuel consumption and lower than normal performance, thus leading to reduced engine life.

  1. API Specification: It is the performance specification of the engine lubricating oil, it is composed of two letters, the first is the S(service station) and the second letter is according to the ascending order of the alphabet. This means that each letter represents the oil's performance level for additive factors, corrosion protection, deposit formation (the sludge), dispersion and so on. Every engine has a specified API level to be used, which must also be strictly followed. Using an oil with a performance level below the specified can lead to high fuel consumption, excessive sludge accumulation and reduced engine life.
  2. Automakers' standards and norms: Here's an important point that few people and even mechanics take into account. Every automaker has its own norms and standards, whether in processes or projects. With the part of lubricants it is no different, suppliers must have products that meet the needs of assemblers.

With the three information above you will certainly not go wrong when choosing your lubricating oil. But where to find this information? In the vehicle owner's manual .


Often, as we want a prompt response, we discuss this issue with the mechanic at the garage, or at the gas station, but most of the time the response we have is not what we expected. All we have to do is consult the vehicle owner's manual, it's that simple! As a teacher of mine used to say:


"The difference between people and things is that things have an instruction manual"

And it really is correct, instead of asking around, look in your manual, in it you find the SAE specifications , API and the assembler's standards.


Factory standards are generally poorly understood, represented by numeric codes, but are highlighted for easy searching. It often happens that we have an oil that follows the SAE and API specifications of your car, but that does not comply with the automaker's standards, which is also required.


For this you must locate this information on the lubricating oil bottle, SAE and API are right in front of the bottle and are easily perceived, but what standard or norm does the oil meet? And from which automaker? Where is this data located (on the oil bottle)? These are usually the back of the bottle.


Let's take a Volkswagen Gol 1.0 2008 as an example:


The vehicle instruction manual contains all the information you need to choose which lubricant to use in your vehicle's engine


Locating in the owner's manual informs you that the vehicle can meet three SAE specification, but only one API. Are they:


  • 5W40 SJ;
  • 10W40 SJ;
  • 15W40 SJ.
