Informative Content

Olho no Óleo Mais information about the tested products. In addition, we provide the public with the information and knowledge they need to make informed decisions about the quality and performance of lubricant brands based on the data. This is an independent work, if you want to contribute to the improvement and development of this work become a Subscriber Plus.

Below is the scope of analysis adopted to survey the information published in the videos, which presents the physical / chemical tests that are always performed with new lubricants, initially with engine oils, but oils for manual and automatic transmission will also be soon understood , differential, transfer box, that is, all types of oil that we can find on the market with applications in automobiles, motorcycles, pickup trucks, light and heavy trucks.


All tests applied to the samples collected by Olho no Oil Mais are performed at ALS Global , and follow the same standard, so that we can make comparisons between different producers, but such comparisons are made between products with the same characteristics (standards and / or specifications) ).

Verifications of information pertinent to the product label and packaging are carried out, such as: description, composition, date of manufacture, validity, batch, ANP registration, seals and seals.

The samples are kept for six months. Any doubts on the part of the manufacturer about the data presented for a given sample must be known before the retention period.

If a lubricant manufacturer has independent test data demonstrating that its lubricant offers higher quality and / or performance, and other information pertinent to the composition of this tested lubricant, we receive this information and remain prepared to publish it on this website, if and when provided .


Olho no Óleo Mais selects, collects and analyzes 4 brands of lubricants per month. These samples are selected at random, collected in the direct sales market to the final consumer, tested independently, and all results are published through exclusive videos on this website without the influence of the brand manufacturer, or anyone else.

Among the collected lubricants can be included products with and without API, ACEA, ILSAC, JASO certification.


This Group is very important not only to measure the quantity of additives, but also to monitor the lubricating oil supplied in the equipment. They identify harmful operational failures for components, such as incorrect oil supply for application and mixing.

KINEMATIC VISCOSITY at 40 ° C and 100 ° C

It is defined as the resistance that the fluid offers to the flow. It is one of the most important characteristics in controlling the use of fluids and must be kept within the limits established for the service of the oil.


It represents the behavior of the oil viscosity when varying its temperature. The higher the index, the more stable its viscosity with temperature variation.



The high concentrations of particles suspended in the oil are the main villains in terms of reducing the service life of hydraulic components and engine injection systems. ALS-Oilcheck adopted the ISO 4406 -1999 standard (4 µm, 6 µm, 14 µm) to dispose of the results, with the objective of guiding the customer in the proper maintenance practices to reduce and control the level of particle contamination.



Total basic number - responsible for indicating the amount of active detergent additive in the fluid.

It can be defined as the ability of lubricating oil to neutralize combustion by-products or acidic compounds arising from oxidation, in internal combustion engines, the higher the TBN load in these lubricating oils, the greater its ability to neutralize combustion by-products and acidic compounds that form during the operation of the equipment.



Total acidity number - used to indicate when to change the oil.
The TAN is a very important feature in the control of the useful life of some lubricants, as well as an indicator of great utility in the prevention of mechanical failures (Predictive Maintenance) in some equipment. Chemically, the TAN represents the amount of alkaline substance (expressed in mgKOH / g) necessary to neutralize the acids present in the oil, resulting from the oxidation that occurred in the operation of the equipment or resulting from contamination.


Chemical incorporation of oxygen and loss of fluid performance due to oil usage time, adverse or abnormal operating conditions or internal overheating. Test carried out by Infra Vermelho whose main objective is to identify substances present in the oil.



Indicator of the percentage of water present in the oil.
