1. Why change the oil?

Exposed to the normal operating conditions, the oil is always exposed to several factors - like extensive heat for instance - that will gradually increase the oxidation and consume the lubricant’s alkalinity reserve which will reduce the lubricant’s ability to protect the engine from the acids coming from the combustion process.

2. How often should I change the oil?

The drain interval will rely on the Lubricant and the OEM (Original Equipment Manufacturer), so please check the manuals to choose the required lubricant and follow the drain interval recommended by the OEM.

3. Could it be dangerous if I forgot to change my oil on time? What are the consequences?

Normally the OEM will indicate the drain interval after setting a safety margin, but nevertheless it can be quite dangerous to the engine if the drain interval was neglected. The consequences may differ but it can be very severe (Corrosion).

4. What is the engine oil for?

Engine oil has 5 main functions:

  • Friction reduction: By providing an oil film to separate interactive surfaces.
  • Cleaning: By flushing dirt particles away from lubricated surfaces.
  • Cooling: By reducing friction and removing excess heat.
  • Protection (Corrosion resistance): By reducing the corrosive processes caused by air and water.
  • Sealing: Providing the sealing effect required for efficient combustion.

5. How do I choose the best oil for my car?

The OEM (Original Equipment Manufacturer)should indicate clearly the appropriate type of oil in the manuals.

6. Are there different types of engine oils for different seasons? How important is it to change the oil according to the season if this is the case?

Multi-grade Engine oils can be used for different seasons. However the OEM may indicate different viscosities depending on the ambient temperatures, so please follow the OEM recommendations to get the best performance possible.

7. Could I stock engine oil or does this affect its quality?

If the storing conditions are good (away from heat, direct sun, moisture and its original sealed pack) the engine oil can be stocked following the recommended shelf life indicated on the pack or in the lubricant’s MSDS (Material Safety Data Sheet).

8. For how long can I stock engine oil packs?

If the storing conditions are good (away from heat, direct sun, moisture and its original sealed pack) the engine oil can be stocked following the recommended shelf life indicated on the pack or in the lubricant’s MSDS (Material Safety Data Sheet).

9. How can I stock engine oil packs?

If the storing conditions are good (away from heat, direct sun, moisture and its original sealed pack) the engine oil can be stocked following the recommended shelf life indicated on the pack or in the lubricant’s MSDS (Material Safety Data Sheet).

10. I still have 2 liters left from a pack I used for top up, how long after opening the pack can I use the oil and could its quality be compromised by time?

The time may vary greatly depending on the storing conditions, so please try to keep the pack away from heat, direct sun and moisture.

11. Is there a sealing for the lubricants pack? Where is it or how does it look like?

Yes, every pack should be sealed, different pack size have different types of seal.

12. Do you do Oil Analysis?

Yes, we have several types of oil analysis. Please contact us on the below coordinates to get the full details. Or check http://www.total.eg/pro/lubricants-industry/an-home.html to learn more about it.

13. How could new technologies in engine oils help my engine and how significant is it?

New engines are constantly designed to meet the stringent environmental requirements. In consequence new lubricants are developed to comply with these new engines (Low SAPS, Fuel Economy). Using the right lubricant will directly affect the performance of the engine.

14. How does oil cleanse my engine?

The engine lubricants have detergent and dispersant additives responsible for cleaning the engine.

15. How does oil protect my engine from corrosion?

The engine lubricants have alkalinity reserve (T.B.N.) responsible for neutralizing the acids generated throughout the combustion process.

16. What happens to used oil? Where does used oil go?

In Egypt, the used oil collection is exclusive to special governmental companies.

17. What is synthetic oil?

Synthetic oil is a lubricant with base oil consisting of chemical compounds that are artificially made (synthesized). It is a substitute for lubricant refined from petroleum (mineral base oil).

18. What is the difference between synthetic and semi synthetic oil?

Synthetic oil is a lubricant with fully synthetic base oil while the semi synthetic oil is a lubricant with a mixture of mineral & synthetic base oils.

19. Why choose synthetic oil?

Synthetic oil offers superior mechanical & chemical properties than those offered by conventional mineral oils. Those properties allow operation at higher temperature, extending application life time & longer oil drain interval.

20. What is a monograde oil?

Mono grade oil is suitable only for use in a narrow temperature range which may not offer the required engine protection level outside this range

21. What is a multigrade oil?

Multi grade oil is suitable for use in a wide temperature range which offers high level of engine protection.

22. What are the abbreviations on the labels of the oil packs stand for? Or what does it mean?

SAE: Stands for Society of Automotive Engineers which is responsible of classifying the viscosity grades of engine oils. API: Stands for American Petroleum Institute which is responsible of classifying the performance levels of engine oils.

23. What are the advantages of a multigrade oil?

A multigrade oil offers high level of engine protection over a wide range of operation temperature.

24. Can I add additives in oil?

Oils are delivered with the appropriate types & amounts of additives so it’s prohibited to add additives to the oil as they may not be compatible with the existing additives and cause oil deterioration.

25. Can I put in my gear-box the same oil as in my engine?

OEM recommendations must be followed, some gearbox (for some trucks for instance) could recommend mono-grade engine oil for the gearboxes. But normally a special gearbox oil is required.

26. Can I use diesel engine oil in a petrol engine, and vice versa?

Yes, but be aware of the Original Equipment Manufacturer (OEM) viscosity grade (SAE) & performance level (API, ACEA & JASO) recommendation.

27. Can I mix two different types of oil?

A compatibility test must be done between the different types of oil to check the possibility of mixing.

28. What causes oil pressure to drop?

Pump problems or a change in the oil viscosity (due to high temperature or fuel dilution) may be the cause for a pressure drop, so always follow the OEM recommendation for optimum results.

29. Does the oil have to be topped up and how do I do this?

Oil level must be checked on weekly bases & incase of low oil level then oil top up is a must.

Oil top up procedure:
  • Switch off the engine & wait a few minutes for the oil to settle.
  • Remove the dipstick and wipe it clean
  • Push the dipstick all the way in, wait a moment then withdraw it to check the level. The oil should be between the two marks - not above the top mark or below the bottom mark.
  • If the level is low, remove the oil cap and add a small amount of oil using a funnel. The scale on the side of the bottle will indicate how much has been added. Continually check the level by repeating steps 2 and 3.
  • Once the level is correct, ensure the dipstick and oil cap are secure and any spilt oil has been wiped away.

30. If I top up my engine oil, will I ever need to have a complete oil change and how frequent?

The original equipment manufacturer (OEM) manual states the oil drain interval that must be followed even if a top-up is made.

31. When do I top up my engine oil and when do I change it?

Engine must be topped up with oil when the oil level is below the dipstick bottom oil mark and the complete oil change must be done when the oil reach the drain interval stated in the original equipment manufacturer (OEM) manual.

32. How can you judge lubricant performance?

First the performance is indicated (API, ACEA and JASO). Also close oil monitoring will give an indication about the engine condition.

33. Why TOTAL lubricants?

34. What is the difference between engine oil and lubricants?

Engine oils are lubricants with specific chemical & physical properties that fulfill the requirements of the engine OEM and international standards.

35. What is a lubricant?

Lubricants aim to separate moving parts to reduce friction that causes heating & surface wear.
