Engine Performance Comparison:
Catalytic converter performance
It is important to make sure the catalytic converter performs great. Usually, when an engine runs, it burns off small amounts of vapors which can easily get into the car’s emission system and produce by products like phosphorous which may poison the catalytic converter.
Moreover, if an engine misfires, it may cause incomplete combustion which causes overheating and also indicates a faulty converter.
Castrol GTX is formulated with titanium based fluid technology and a micro thin layer which helps keep the engine protected from any harmful deposits formation.
Moreover, the motor oil has special molecules present in it that cling to engine parts and reduce oil consumption by reducing any oil vaporization. Thus, the car’s emission system is protected and the catalytic converter performance is maintained.
Castrol Edge uses the TriShield technology which provides extra protection to the engine from sludge deposits and helps enhance the engine’s performance.
The anti oxidants helps reduce any oil vaporization and thus the oil particles do not evaporate easily and so do not enter the car’s emission system.
How they reduce Sludge?
When the engine stays heated for long intervals, oxidation takes place and the engine oil comes in contact with oxygen.
The oil particles further break down and combine with dirt to form carbon and then in the presence of gas, coolant and water, this eventually forms a thick sticky paste known as sludge.
Sludge can cause various issues such as blocking the valve and reducing oil pressure which stops proper oil circulation in the engine that leads to damage.
Castrol GTX uses the fluid titanium technology and intelligent molecules which attach to various engine parts to provide extra protection to it.
Moreover, special additives such as detergents present in this motor oil provide superior protection against any harmful sludge built up.

The detergents plus rust and corrosion inhibitors present further facilitate the reduction of sludge built up and prevents any reaction from taking place between the metal surfaces and moisture.
Do they provide Oil burn-off protection?
Oil Burn off protection is vital since heated engines can cause the oil molecules to evaporate and thus result in the oil level to drop.
This would mean increased oil burn off would result in more fuel consumption and you would have to change the motor oil more frequently.
This issue also leaves the engine unprotected and produces harmful emissions which increases sludge deposits, causes poor low temperature start and performance loss.
Castrol GTX uses additives which provide superior protection against any thermal breakdown and stops oil molecules from evaporating.
The anti oxidants further provide oxidation stability and reduce any oil vaporization.
