FAQ

Q: At what interval should I change the oil in my   car?

A: You should follow the change interval as recommended in the owners manual. A good general rule is to change the oil every 3000 miles (5000 km), or every six(6) months which ever comes first.

Q: What does the “W” mean in 10W30?

A: The “W” stands for winter, and designates that the oil is suitable for colder climates.

 

Q: How do I tell the difference between detergent and non detergent oils?

A: All engine oils contain the detergent additive to reduce combustion deposits. Hydraulic oils do not normally contain the detergent additive except in some special formulations identified as “Detergent Hydraulic Oils”. The non detergent oil is sometimes identified as “Pump Oil”.

Q: Will changing my oil more often than the recommended interval outlined by my auto manufacturer prolong the life of my engine?

A: It is important to understand the severity of your operating conditions. Under normal driving conditions the OEM has set a recommended oil change interval based on many hours of testing and research into the desired amount of time needed to get optimum life from the engine, changing oil more often wastes oil, your time, and money. MIDCO Motor Oils are formulated to the highest standards and offer the best possible protection for your engine

Q: What is meant by the TBN of oil?

A: TBN stands for Total Base Number, which is a measure of how well the oil can neutralize acidic combustion by-products. The higher the TBN of new oil is not always a good indicator of how well the TBN will last when the oil is subject to extreme heat and corrosive exhaust gases. (TBN retention) Some oils with high starting TBN’s are used up very quickly leaving little protection against corrosive by-products that form in the used oil towards the end of the drain cycle. MIDCO heavy duty diesel engine oils have proven to offer excellent TBN retention and corrosive wear protection under severe operating conditions and extended service intervals

Q: What does zinc do in oil?

A: Zinc or ZDDP is widely used as an anti-wear additive used in many types of hydraulic and engine oils to protect heavily loaded parts from wear. ZDDP is a last resort against metal-to-metal contact.

Q. Is it true that when oil turns black it’s time to change?

A: Not necessarily, because oil can turn black due to improper draining of oil while changing, poor maintenance, or quality of previously used oil and fuel, excessive carbon deposits on engine parts etc.. In fact oil will tend to blacken as it cleans the engine & various parts and accumulates dirt particles in itself

Q. Can any oil be used for any vehicle?

A: No.  The type of oil is specified based on the design of the vehicle and it is normally recommended by OEMs (full form)

Q. Why we need to change the oil?

A: The oil quality gets reduced while in service due to oxidation of the oil and/or contamination of the oil and / or depletion of the additives as it gets used up during its service. Oxidation of the Oil in presence of air & high temperature produces acidic and gummy substances. If it is allowed to increase beyond certain limits then it will start corroding the equipment or leave unwanted deposits on the moving parts. Similarly contamination of the oil with water, dust, dirt and soot from combustion products leads to corrosion and abrasive wear. The TBN, Anti-wear and performance enhancing additive gets used up in service and below certain levels will not be in a position to protect the equipment. Because of these primary reasons that we need to change the oil once it looses its useful life to protect our costly equipment.
