Checking what we need

The first step we must take to buy one of these oils is to verify that it is really what we need . Something for which we can resort, first of all, to what the vehicle owner’s manual tells us. In general, 5W30 type oil is used in vehicles of a certain power and level, so if you have a modern and powerful vehicle, your car will probably use it.

However, it is also important to take into account the environmental conditions in which the oil is to be used. In Spain it is common for temperatures to skyrocket in summer, so it is possible that the oil falls short of protection on the hottest days in the south of the country.

For reference, this oil works at temperatures down to -30 degrees, which is not a problem, but the maximum working ambient temperature reaches 30 degrees, which probably falls short in this summer time. So it would be convenient to verify if the product is suitable for what we are going to do with the car. In any case, this must be verified by a workshop professional, in order to know exactly what is best for us.

 

Manufacturer standards

Since we are talking about a high quality motor oil, designed for vehicles with considerable demands, there are several vehicle manufacturers that have decided to go beyond the standard and establish an additional standard for the oils they use in their vehicles. Something that is essential to comply with considering how much your vehicle costs and the positive advantages of using the correct oil.

Among these brands are those of the Volkswagen group, which in its different variations establish certain models for which the use of an oil with a certain standard is required. Something similar happens with BMW, Ford, General Motors, the PSA group (Peugeot and Renault), as well as many other brands on the market.

The best way to know if your vehicle requires one of these more specific oils is to take a look at the manufacturer’s instructions. Anyway, if your car is modern and has a particle filter, you have a good chance that it is. Especially if it is among the brands that we have discussed above.

 

Special properties

In addition to the manufacturer’s standard and the oil itself, it is also advisable to check what the oil offers us as an extra, since some products have specific properties that improve the operation of the engine.

Among these functions we have those that include some oils to work better with vehicles equipped with a particle filter. These oils remove more dirt and facilitate the work of that filter, so that only the smallest particles have to be removed. Something similar to what high detergent oils do, which remove more dirt from the engine.

Another additional effect of these oils is the option to reduce fuel consumption, through less friction and a more fluid operation of the engine. Finally, some oils reinforce the conventional thermal properties, so that in higher power engines overheating is avoided on the road. They are little extras that can be interesting.

 

Can format

As a final step, there is one aspect to cover. We refer to the format or quantity of oil to buy. If you want to completely change all the oil in your vehicle, it will always be cheaper to buy a whole 4 or 5 liter can than to buy small cans.

These smaller cans have a capacity of one liter, being suitable for carrying them in the car and refilling the oil as we go for kilometers. Among other things because these small cans are more manageable for filling and they are also interesting so as not to spend so much on a large can that, with the fillings, we are not going to take advantage. Especially if we take into account that, once opened, the oil loses properties.

 

 

 

Frequently asked questions

 

Q1: How many km is the 5w30 oil changed?

The change interval of a 5W30 oil is not something that is measured by the type of oil itself, but depends on the base you use. In general, this type of oil usually has synthetic bases, whose change is recommended around 15,000 kilometers.

In case this base is semi-synthetic, the oil should be changed every 10,000 kilometers, although these types of oils are used less and less. Finally, we have the oils called Long Life or long life, whose change reaches 30,000 or even 50,000 kilometers. Anyway, we are talking about theoretical assumptions, since the actual mileage will be given by the conditions of use and other parameters of the environment in which we use the vehicle.

 

Q2: Which oil is better, 10w40 or 5w30?

Well, the real answer depends on many factors. On the one hand, the use of a certain oil, as far as SAE is concerned, is given to us by the manufacturer. So this should be the reference to use. It is true that 5W30 oil has better cold starts, but it has a higher consumption when hot, so that in summer it will surely spend more than its comparator. On the contrary, this one is denser in summer, but it also makes starting a bit difficult compared to the 5W30, so in the end it all depends, as we have said, on what the manufacturer recommends and the surrounding temperatures.

 

Q3: Who makes Ford 5W30 oil?

Ford 5W30 oil is typically manufactured by Motorcraft. This company is a Ford subsidiary created precisely to supply parts and spare parts to both Ford factories and workshops, also offering these parts to the general public, through different channels. Since they are oils created specifically by the manufacturer, they are a great option for keeping Ford vehicles in good condition, although obviously any other oil that meets their standards can be used.

 

Q4: Which oil is denser, 5W30 or 5W40?

Following the SAE scale itself, obviously 5W40 oil is going to be denser than 5W30. In fact, this 5W30 oil is the one that is usually recommended to use when the 5W40 oil is too dense due to the environmental conditions of the environment in which the vehicle circulates. Although this change should always be done after consulting the manufacturer or a specialized workshop.

 

Q5: Where to dispose of used 5W30 oil?

The 5W30 oil that we have removed from our vehicle should be deposited either in a clean place or in the place where we buy the new oil, which has the obligation to receive it so that it is properly treated. It is key that we do not throw the oil into the conventional garbage and even less into the environment, since it is an extremely polluting waste.

 

Q6: What 5W30 oil consumption is normal?

5W30 oil has the disadvantage of being very fluid at high temperatures, so that a high consumption of it in summer is reasonable. However, we are talking about no more than one liter per 10,000 or 15,000 kilometers. In the event that this oil is consumed a lot in winter or in a greater quantity than indicated in summer, it will be necessary to review the vehicle’s system, as well as check that the oil is adequate, and it may be advisable to change to a 5W40, plus dense and less fluid in the heat.

 

Q7: How to tell if a 5W30 oil is bad?

In general, there is no way to tell if a 5W30 oil is bad beyond looking at what it looks like. If the oil is in its can, the appearance of a bad oil is different from the normal honey color, presenting turbidity, residues and a different color. If it is an oil that is in a vehicle, in general, it will be more or less blackish, although it will retain honey tones depending on its age. However, if the appearance is earthy, excessively sticky, or a different hue, it may be in poor condition.

 

Q8: Why does water appear in the 5W30 oil?

The presence of water in the 5W30 oil that we have in our engine is a serious problem, since it shows the existence of a leak or communication between the cooling circuit and the lubrication circuit. The most dangerous option, as it is the most expensive, is that this mixture has been produced in the cylinder head gasket. In this case, it is necessary to disassemble it for inspection. The other option is for mixing to take place in the oil cooling zone, which is cooled with the water or engine coolant. The repair is somewhat cheaper, although it is still expensive.

 

 

 

How to use a 5W30 oil

 

Oil is a fundamental element for the good health of our engine . That is why it is essential to always keep it at the level and change it when the manufacturer indicates. Skipping periodic maintenance is a wrong saving measure that shortens the life of the engine. Therefore, so that you can do it yourself, we are going to give you some instructions on how to proceed with that oil change .

 

 

 

Placing the vehicle

The first thing to do is place the vehicle on a flat and stable surface. The most appropriate is to use a workshop lift or an area with a pit. Many workshops rent machinery so that we can do the maintenance ourselves. If this is not the case, find a flat area and secure the vehicle well, so that it does not move. Take the opportunity to circulate a bit with the car before changing, since hot oil always comes out better than cold, being more fluid. Of course, be careful when handling it to avoid burns.

 

Proceeding to change

The next step is to extract the oil inside. A process that we can do from above or below. To do it from above, we are going to need an oil aspirator, which is inserted through the area of ​​the rod and removes everything it finds in the crankcase. The other option, common in domestic oil change, is to remove the crankcase plug, place a container to collect the used oil and wait for it to drain. In the latter case, don’t forget to put the cap back on, better with a little Teflon on the screw, before moving on to the next step.

 

Refilling with new oil

Once the old oil has drained well, it is time to pour in the new oil. This new oil is poured through the cap of the tank located on the top of the vehicle, either with the spout of the can or with a funnel. It is important to know in advance how much oil to pour in, checking with the side of the can the amount that we have poured, in order not to spend or have to spend all the time looking at the dipstick.

 

 

 

Oil control

After filling the oil, putting in the cap and dipstick, and closing the hood, it’s time to start the vehicle. If all goes well, we shouldn’t see any witnesses on the dashboard. But if the oil warning light comes on, it will be necessary to add something else to the engine. We will have to repeat this same process after a few kilometers or a couple of weeks, to see that the oil maintains the level. And if all is well, it only remains to recover the habit of checking engine levels that we have established, which should not be longer than 3 months.

 

Discard the oil

Although it is an additional part of the process, we do not want to forget about it. It is essential that you deposit the used oil in a clean point or in the store where you bought it, so that it is recycled. Used oil is extremely polluting, so it must be treated as hazardous waste.
