Total Quartz 9000 Energy and Mobil 1 Fuel Economy are both fully synthetic oils that are created to be used in diesel and gasoline engines.
Energy is made with age-resistant technology, providing extra thick oil film around the moving engine parts to reduce the friction between them. It has a higher quantity of silicon to reduce the formation of foam. It has special viscosity modifiers which increase its kinematic viscosity at both medium and high temperatures.
Economy is a catalytic converter responsive oil having strong detergents to provide excellent cleaning to the engine.
It is highly resistant to break down at high temperatures which decreases oil consumption and improves the fuel economy.
The viscosity index of respective oil is much higher due to the lower effect of temperature on its kinematic viscosity. It is specially formulated to perform well in winters. It is made to be used for long oil change intervals.

Kinematic Viscosities Evaluations
The kinematic viscosity of an oil is the extent of its ability to allow energy through it. A greater kinematic viscosity indicates the better lubrication properties.
On the other hand, viscosity index is the measured effect of temperature changes on the kinematic viscosity of the oil. Pour point temperature suggests the minimum temperature below which the liquid is incapable to stream in winters.
Kinematic viscosities of the Energy are higher at both medium and high temperatures, but its viscosity index is lower due to the higher impact of temperature variations on its kinematic viscosities.
Its pour point temperature is also higher compared to its counterpart, resulting in a poor performance in winter weather.
While Economy has a higher viscosity index due to less effect of temperature led changes on its kinematic viscosity. However, its kinematic viscosities are lower at both medium and high temperatures. This oil excels in cold conditions due to its much lower pour point temperature.
| Oils (0W-30) | Kinematic Viscosity @ 40 o C (cSt) | Kinematic Viscosity @ 100 o C (cSt) | Viscosity index (VI) | Pour point Temperature (°C) |
| Total Quartz 9000 Energy | 68.7 | 12.3 | 170 | -45 |
| Mobil 1 Fuel Economy | 53 | 10.1 | 181 | -54 |
Effect on the Efficiency of Catalytic Converter
Every oil has phosphorus and zinc present in it to reduce wear of the engine. The problem arises when the oil burns, these additives are converted into ash. This ash poisons the catalytic converter and impedes its operation. The oil with a lower amount of these additives will produce a lower amount of ash when burnt.
After the chemical composition test, the concentrations of phosphorus and zinc were found higher in Energy.
This means that it will produce a higher amount of ash when burned, therefore, this oil is not preferable to be used with the catalytic converter.
The lower numbers of zinc and phosphorus put the Economy ahead of its competitor regarding catalytic converter performance. Since this oil will generate a lesser quantity of ash upon burning, it will scarcely affect the efficiency of the catalytic converter.
Difference of Oil Volatility
Flashpoint (vapors ignition point) temperature of the oil is directly proportional to its volatility whereas the volatility varies upon the total amount of lighter molecules available in that oil. The oil with a greater number of lighter molecules will evaporate swiftly and will provide a lower oil burn-off protection.
Energy has a slightly lower flash point temperature, indicating a little higher volatility rate and a lower oil burn-off safety of this oil.
On the other hand, the Economy has a slightly higher burn-off protection ability due to its higher flash point temperature, leading to a lower volatility rate of this oil.
| Oils (0W-30 Grade oils) | Flash Point Temperatures (°C) |
| Total Quartz 9000 Energy | 226 |
| Mobil 1 Fuel Economy | 228 |
Evaluation of Engine Wear Reduction
Wear is caused by the collision between the moving engine parts. The oil overcomes this friction by using anti-wear additives which make an oil film around those parts, allowing frictionless movement. The higher the quantity of these additives, the better will be the anti-wear performance of the oil.
Energy has higher concentrations of the primary anti-wear additives zinc and phosphorus while lower quantities of the secondary anti-wear additives i.e., boron and molybdenum.
Even with the lower quantities of secondary additives, this oil surpasses its competitor regarding wear reduction due to extreme numbers of primary anti-wear additives.
The economy has comparatively lower concentrations of basic anti-wear additives, phosphorus and zinc, while its secondary additives boron and molybdenum are higher in numbers. This oil lacks its competitor due to the lower number of primary anti-wear additives despite a higher number of secondary additives.
Engine Cleaning Ability
Sludge is a thick black slurry often found inside the oil which is formed because of a reaction between the dissolved oil, water, and dirt. This sludge is very harmful to the engine as it blocks the pipes carrying oil to it. To avoid the damage of engine, sludge must be removed. So, detergents are included in the oil to fight against the sludge.
Energy uses calcium as its leading detergent whose quantity is very higher along with the very low quantities of magnesium, and sodium as its secondary detergents.
The overall cleaning performance of this oil is very decent, but it is not as efficient as its colleague. It also has some amount of silicon as an anti-foam agent.
The economy employs both calcium and magnesium as its primary detergents while sodium is the secondary detergents. Calcium’s quantity is lower than its competitor while the quantities of magnesium and sodium are higher.
This causes a higher capable oil, regarding sludge reduction. Its silicon quantity is comparatively lower in this oil which dents its anti-foam ability.
TBN Assessment
The bases available inside an oil are expressed in form of Total Base Number (TBN). These bases are necessary as they counterbalance the acids created through the burning process. Since the bases combine with acids, their quantity decreases, and at a certain stage, oil is unusable.
Therefore, if an oil has a larger reserve of these bases, it could be utilized for longer durations.
Energy has a lower TBN, that’s why it has a comparatively shorter oil drain interval of 5000 to 7500 Miles. Whereas the Economy oil has a greater TBN which allows it to be used for longer oil drain intervals of 10,000 Miles.
| Oils (0W-30 Grade oils) | TBN (mg KOH/g) |
| Total Quartz 9000 Energy | 7 |
| Mobil 1 Fuel Economy | 11 |
