What is engine oil made from?
Sunday, August 20th, 2017
Engine oils are made up from two important ingredients – base oils, and additives. Texaco oils are carefully selected from group two base oils and skilfully blended with performance additives to enable the oil to provide maximum engine protection. Note that Chevron is the leader in production of Group Two Base Oils

Can I add additives / treatment in oil?
Sunday, August 20th, 2017
The components of TEXACO oils have been proportioned to reach an optimum result. Adding an additive / treatment may create unnecessary blends and even harmful. TEXACO forbids to adding additive / treatment to oils.

Why is the choice of engine oil so important?
Sunday, August 20th, 2017
Oil is the lifeblood of your car. If the wrong kind is used, the engine is at risk of increased wear and corrosion. Formation of blockages can also lead to engine seizure. By putting Texaco Havoline with Deposit Shield Technology oil in the engine, you can carry on motoring with confidence and experience the feeling that your car has just been serviced – all for less than the cost of a tank of fuel.

My engine oil is turning black, does it mean it needs to be changed?
Sunday, August 20th, 2017
The basic function of the engine oil is to lubricate as well as to clean the engine components. Engine oil cleans the black carbon deposits; soot etc. formed on the engine parts due the combustion of the fuel (diesel/petrol) and thereby becomes black. It does not mean that the condition of the oil is not good. Oil can still be used. However ensure that the oil is changed at the drain interval suggested by the car manufacturer/lubricant supplier.

Can I use diesel engine oil in a petrol engine, and vice versa?
Sunday, August 20th, 2017
Petrol and diesel engines have different lubrication requirements. During development, lubricants undergo a number of tests, some common to diesel and petrol engines and others specific to one or the other type, that categorize their performances.

Can I mix two different types of oil?
Sunday, August 20th, 2017
Lubricants are always optimized to meet the requirements of international classifications (API, ACEA). However, there are many ways of formulating a specific type of lubricant. Mixing two oils that have equivalent properties will not pose a problem, but final performance cannot be guaranteed.

What causes oil pressure to drop?
Sunday, August 20th, 2017
During normal vehicle operation, oil is vital to ensures leak tightness between the combustion chamber and the crankcase. The oil pressure indicator shows how well this is being done.
An unusual drop in oil pressure can result from either lower engine oil viscosity due to dilution by fuel (injector problem or use at low load) ; too little oil in the lubrication system (due to an oil leak, excess oil consumption, or failure of the oil circulation pump) ; or even mechanical part wear.

What are the advantages of a quality oil?
Sunday, August 20th, 2017
A good quality oil provides motorists with a number of benefits:
- easier cold start and reduced wear (20 to 30% of engine wear occurs between startup and the time the engine reaches optimal temperature),
- longer engine life,
- fuel savings as a result of reduced friction of moving parts and better engine performance.

Why change the oil?
Sunday, August 20th, 2017
The oil change is an essential operation in maintaining a vehicle in top condition:
- Because lubricants collect particles of internal and external pollution (carbonic matter, particles of worn metal
- Because an oil’s efficacy diminishes because of : – dilution by water and fuel, – oxidation, – the consumption of additives, – shearing

How often should oil be changed?
Sunday, August 20th, 2017
- Ideally every 5000km or 3months whichever comes first
- The frequency recommended by the manufacturer may be modified according to: – The lubricant used, – Vehicle use (country, city, highway), – Thermal and mechanical requirements.
- Never drive with an oil level below the minimum mark on the dipstick Below this mark there is not enough oil, thus causing more rapid circulation of the fluid and accelerated wear on the oil.
- It is recommended to check the level regularly every 1,000 km and especially before a long trip.
