What is conventional oil?

A conventional oil is an engine oil which is made in such a way that its lubricating and cooling properties can withstand extreme temperature variations in addition to providing proper care for internal components of the engine like valves, piston rings, cylindrical sleeves etc. However, this does not mean that if you use synthetic or fully synthetic oils then they cannot provide these functions because quality oils like Castrol EDGE Professional LL03 (for Audi & VW), Pennzoil Platinum (for BMW), Pennzoil Euro Fully Synthetic (for Mercedes Benz) and Mobil Super Synthetic (for Porsche) has been confirmed by independent studies to provide the right kind of protection to internal engine components.

Types of conventional oil

The main types of best conventional oil consumer ratings & reports 2022 include:

The lightest and sweetest, often described as “oily water” because it has been filtered from the first stage of sedimentary rock formation. It is a generic name for a lighter carbon based crude oil condensed under very low pressure and relatively high temperature conditions within porous sandstone or limestone rock formations. These reservoirs may be less than 1% saturated with hydrocarbon material, yet since they usually have enough porosity to allow oil to accumulate before other liquids begin filling the pore space, they will produce economic quantities of oil if given any kind of stimulation. The production rates are naturally very low, however, because these reservoirs offer little or no natural pressure support.

The heaviest oil, viscous and often so thick it appears almost solid at room temperature. It is found in deep, heavily eroded sedimentary basins containing large deposits of extremely small-grained sedimentary rocks known as “source rock.” These source rocks have high concentrations of organic material that are undergoing much higher stages of decomposition than would normally occur outside the basin environment. This much higher level of decomposition creates the heavier hydrocarbon molecules that eventually generate into much larger quantities of oil. Historically, when these heavy oils reached the surface they were burned off in large flares to release energy for steam generation before being used in other ways.

Unlike lighter oils which flow to surface under natural reservoir pressure, many superheavy oil reservoirs require artificial means such as water injection or even mining with explosives followed by steam-assisted gravity drainage (SAGD) in order to achieve commercial flow rates from a well. Because these types of “enhanced recovery” methods have been found to cycle back carbon dioxide when used excessively, they are referred to as greenhouse gas (GHG) emitters in policies designed to reduce GHGs associated with global climate change. Because heavy oils release more GHGs than conventional light oils per barrel, the IEA Clean Coal Center says that, “if production of heavy oil is not reduced, by 2030 it will account for almost one-quarter of global fossil fuel production and two-thirds of the increase in energy related CO2 emissions”.

Extra-heavy oil, which can be artificial or natural. The term “extra-heavy” refers to anything thicker than crude oil (i.e., extra heavy crude oil), but many times these oils are referred to as bitumens. They also occur naturally in some shale formations where they are sometimes known as tar sands or bituminous sands. Because these types of deposits occur above source rock formation temperatures, little molecular change occurs during later reformation into petroleum fluids so carbon dioxide is not emitted during production. Therefore, even though these oils are very viscous, they often require little processing prior to being refined into usable products.

Synthetic oil, known also as syncrude (syn fuel) or semisynthetic oil. This is an extremely broad designation that includes any upgrading process or residue which has been processed to resemble crude oil in viscosity and other physical properties so it can be used in refineries designed for handling conventional oil without major modifications. Although this term should refer only to upgraded hydrocarbons synthesized from raw materials other than petroleum such as coal, natural gas, many times the word “synthetic” refers generically to any fluid produced by non-petroleum means. The most common synthetic oil, referred to as “syncrude” or synthetic crude, is obtained from bituminous (extra-heavy) crude oils such as those found in the Athabasca Oil Sands deposits located primarily in northeastern Alberta, Canada. These oils must go through a lengthy upgrading process that includes adding hydrogen and removing organic sulfur and nitrogen compounds so they can be refined into usable petroleum products.

Gas-to-liquid (GTL)&Coal-to-liquid (CTL) technologies, also known as Fischer–Tropsch synthesis. These methods convert various forms of carbonaceous materials such as coal, natural gas or biomass into different grades of “synthetic fuel.” This broad designation includes not only GTL and CTL processes, but also the use of any synthetic fuel that is derived from non-petroleum sources. Gas-to-liquid (GTL) technology includes not only petroleum-like oils, but also odorless gaseous products such as hydrogen and methane which can be used for fuel or further processing into other useful forms such as fertilizer.

Benefits of using conventional motor oil

Motor oil is designed to protect your engine against many types of wear. It also keeps clean and lubricate all moving parts in a vehicle. The advanced additive packages in today’s motor oils reduce friction to save fuel, produce less smoke, and help lessen the way your engine sounds when you step on the gas pedal. To achieve these benefits today’s motor oils have become much more complex than they were years ago when there were fewer, larger additives in them for simplicity sake. You need multivitamins not just one or two! Some benefits of using best conventional oil consumer ratings & reports 2022 in modern vehicles include:

Lower Cost – As mentioned before, there is no need to invest in much more expensive synthetic oils if you’re operating a vehicle that gets proper maintenance -you change the oil when needed. This will save you lots of money over time. 

Proper Lubrication – As long as you have a properly maintained vehicle, a quality brand of best conventional oil consumer ratings & reports 2022 will provide ample lubrication for the engine. 

Low Residue Deposits – When synthetic oils came on the market, many people claimed that they left a lot more residue in engines than conventional oils.

How to choose the best conventional oil for your needs

There are many factors to consider when selecting the proper oil for your needs and some of them include: filter capacity (1 micron vs. 5 micron), viscosity (SAE grade), ambient temperature range, filtration level, shear stability/Rust Protection Factor, additive package compatibility with gaskets & seals, metal compatibilities with different engines and the list goes on into infinity. The purpose of this article is to help narrow down some of that infinite list into a more manageable solution set. In order to do so we have provided four very broad categories below which should cover most if not all conventional oils available in the marketplace. Let’s begin:

Oil Cooler Flow Specifications – There are two main specifications we look at when evaluating conventional oil, and those are: flow rate and viscosity temperature – Viscosity Index. A good rule of thumb is to select an oil that has a higher flow rating than indicated by your vehicle’s owner manual or find the maximum flow rating of your engine’s oil cooler(s) and then use 10% less than that number as a minimum specification for choosing your new oil. Most best conventional oil consumer ratings & reports 2022 today have a Viscosity Index of around 110 which is more than suitable; however we would like to see it closer to 120 or better yet 130 which indicates a higher degree of shear stability and better viscosity control.

Oil Filter Capacity – This one is quite simple and easy to understand: The higher the capacity, the longer you can go between oil filter changes and in most cases this will equate into less frequent oil drain intervals; however there are exceptions to this rule such as high performance turbocharged/supercharged engines which generate more blow-by (an indicator of higher internal component wear). Such engines may require more frequent oil changes due to excess contaminants generated by very high combustion chamber temperatures even though they have a very large oil filter. Typically it is wise to use an oil that has a filtration level of 20% or greater than whatever your vehicle’s OEM specifies for extended drain intervals unless you have other reasons not to.

Filter Compatibility – If you are using an OEM oil filter, it is very important that the best conventional oil consumer ratings & reports 2022 you choose is compatible with its construction and materials or it can weaken and/or damage the filter and cause oil flow issues (leakage) as well as compromise filtration efficiency; therefore we recommend utilizing a known compatible filter.

Temperature Range – Today’s new oils are manufactured with much better cold weather performance than older conventional oils which means they won’t thicken as much in colder ambient temperatures (below 40°F). The general rule of thumb for this figure is to subtract 20°F from your average high temperature range to get the approximate lowest temperature rating for your chosen oil. For example if your average high temperature range for the year is 90°F then you should select an oil that has a 40°F rating or better. This rule also applies to colder climates where sub-zero ambient temperatures can be encountered, however in such cases it’s best to consult your vehicle’s owner manual as well as take any other precautions necessary to protect yourself and your engine from possible cold weather damage.

Oil Viscosity – Unless you are challenging the laws of physics by asking your engine to operate beyond its design parameters via forced induction such as turbo charging, supercharging or extreme RPM levels, viscosity isn’t really much of a concern since most engines today are designed to run within a rather narrow range between SAE 5W-20 and 10W-30.

Oil Category – Finally, you should always choose an oil that falls within the same category or range of viscosity as indicated in your vehicle’s owner manual since most manufacturers have specific oil weight specifications for certain models even though the difference may be miniscule. For example, if your vehicle requires 5W-20 then this would rule out using a best conventional oil consumer ratings & reports 2022 that has a lower viscosity rating such as 0W-20, however it wouldn’t necessarily preclude you from using a mineral based oil that is formulated to meet present API/ILSAC standards along with SAE 5W-30 which is present by many manufacturer’s today in order to avoid warranty issues due to incorrect oil specification.

Tips for using and maintaining a conventional oil system

A typical pre-purchase inspection includes: an exterior and interior walk around of the car; an in depth visual examination of major systems like brakes, suspension system, exhaust system, powertrain/engine, AC/heating & cooling system; functional tests of headlights & taillights, turn signals etc. The idea is to not only provide you with a comprehensive list of current existing problems but also potential future issues that may arise down the road.

A pre-purchase inspection should be performed by an experienced trained technician familiar with common problem areas specific to your year, make and model vehicle. The inspector should have specialized tools for testing specific problem areas along with calibrated meters/scales for accurate evaluation. For example, checking the level of transmission fluid requires using a calibrated dipstick. Some service centers will include this in their diagnostic fee while others charge extra for it.

Check you local yellow pages or online directory under “Automotive Inspection” or “Pre-Purchase Car Inspection”. Also talk to friends & family members who own cars similar to yours about reputable facilities they recommend. There are also many sites online with lists of reputable pre-purchase inspection facilities in your area.

Can I go for a conventional oil change at 5000 miles/8000km?

No, it is not recommended especially if you are using a quality synthetic or semi-synthetic oil because these oils have been formulated with specific additives which are responsible for providing proper lubrication and cooling properties to the engine. These chemicals are designed in such a way that they can withstand extreme temperature variations but also provide enough care for your internal engine components. Going too early may result in not only removing some of these additives that are still active inside your engine but can also cause other problems like startup issues, lack of power etc (Best conventional oil consumer ratings & reports 2022).

Can I go for a conventional oil change at 6000 miles/ 10000km?

Yes, you can do that because by this time most of the additives in the oil have already done their job. However, if your car’s manufacturer recommends you to change your engine oil at 2000 or 3000 miles then you should follow what they recommend. If they don’t mention any specific figures then use Castrol EDGE Professional LL03 (for Audi & VW), Pennzoil Platinum (for BMW), Pennzoil Euro Fully Synthetic (for Mercedes Benz) and Mobil Super Synthetic (for Porsche) for best protection.

How often do you need to change your oil if you don’t drive much?

It’s not just about miles: If you don’t drive your car a lot, your oil still needs to be kept fresh. Even if you drive fewer miles each year than your automaker suggests changing the oil (say, 6,000 miles, with suggested oil-change intervals at 7,500 miles), you should still be getting that oil changed twice a year.
