Oil is as important to an automobile as blood is important to animals. With the advent of 16-valve engines, fuel economy, super-speed cars, super-silent cars and compact engines, greater attention becomes assignable to the composition of automotive engine oils. The primary function of motor oil is to lubricate rolling metals in the engine to avoid wears caused by friction and corrosion. But in reality, engine oil performs more functions than this as can be seen below:
- It acts as lubricant preventing rubbing surfaces of metals from quickly wearing away
- It acts as coolant to the engine transferring heat away from the combustion cycle.
- It also cleans combustion by-products, iron filings and acids away from the engine.
Automotive Manufacturers have specification of oil grade that is suitable for maintenance of all their brand of vehicles. This is usually contained in the owner’s manual with a recommendation of frequency of replacement of engine oil to keep engine running smoothly and for a long engine life. Prompt oil change is also important to prevent buildup of sludge.
Our Oil Services
As part of our customer support services and installation services, we offer oil change services to customers who buy maintenance materials from the products side of wheelas.com. Our aim is to guarantee full satisfaction to our customers by ensuring that the products we sell are not left to quacks to install. Therefore, the prices quoted for our services is mainly service charge, not including cost of materials.
To deliver this excellent service, we have two service plans out of which you can choose anyone that is convenient for you. All the two service categories have in common compliance with oil grade and quantity recommendation by manufacturers.
- Basic Oil Service
- Full Oil Service
Look below what we offer under each of the oil service categories:
|Basic Service||Full Service|
* Oil draining
* preventive diagnosis

Sludge build-up is the solidification of oil caused by extended delay in replacing old oil, overheating engine, long period of demobilizing a vehicle without oil change (take 12 months for instance). If oil sludge is left uncured, oil channels can get blocked and starved of lubrication, cooling and cleaning and the engine may be caused to seize. In modern engines, this will initially cause the ‘service now’ or ‘Maint Rqd’ alert to come up as a warning that the engine oil needs to be replaced and may result in serious damage if ignored. When sludge buildup has gone so bad, the only solution to cure it might be flushing which also is not without its own risk. Beware that flushing of sludge buildup may push bits of sludge to lodge where they can do further damage so, use only experienced engineers.
Types of Engine Oil
Oils are graded according to the materials used in preparing them. The basic categories are synthetic oils made from organic materials, semi-synthetic which is a blend of synthetic and mineral oil and mineral oils which are derived from petroleum products.
Synthetic (0W-30, 0W-40, 5W-40)
- Efficient fuel system
- Enhanced engine performance and power
- Engine protection from wear and deposit buildup
- Good cold starting and quick circulation in freezing temperatures
- Gets to all moving parts of the engine quickly
Semi-synthetic (5W-30, 10W-40, 15W-40)
- Good protection within 10 minutes after start out
- Very well better at reducing engine wear
- Requires lesser frequency of oil change
Mineral oil (10W-40, 15W-40)
- Basic protection for variety of engines especially in high temperature regions
- Frequent oil change is required
Oil can also be identified by its viscosity. Viscosity is a measure of oil’s resistance to flowability (so to say). Viscosity can also be described by how thick the oil is. The thicker an engine oil, the higher its viscosity.
Multi grade oil (e.g 5W20)
This is a grading that considers two temperature conditions, cold and hot conditions. As oils heat up, they naturally get thinner or lighter. Low viscosity oil gets too thin when hot for most modern engines. Thus, it is unhealthy in high temperatures as the additives get broken down and prone to drying up. Also, a very thick oil will not flow quickly enough to protect the entire lubricating surface during a cold start, and so a low viscosity oil is required to correct this. Hence, the multi grade oil. In a typical multi grading like 5W20, the first letter ‘5’ stands for cold (5 °C or lower), ‘W’ for winter and ’20’ for a hot temperature (of 20 to 30 °C). Therefore, an oil that is graded as 5W20 is expected to perform safely and efficiently under a very low temperature and high temperature conditions.
