Choosing the right motor oil for your vehicle can be a very painstaking process if you aren’t sure what exactly you are looking for. However, it is extraordinarily important that you make the right decision in order to avoid costly repairs due to engine damage. Whether you are looking for oil for your car, ATV, truck, or marine vehicle, there is a wide variety of Amsoil products to choose from.
In this article, I’m going to talk about diesel oil. More specifically, what the different types of diesel oil are, is diesel oil better than oil for gasoline engines, and can you use diesel oil in your gas engine. If you are more interested in learning about the different types of oil for gasoline engines, feel free to check out my article on the differences between synthetic oil and conventional oil.
Two Types of Diesel Oil
Originally, there was only one type of diesel oil – API CJ-4 diesel oil. However, about two years ago, two different types of diesel oil were developed with the intention that each one would be used in certain applications. API CK-4 oils would be meant for off-road vehicles while API CK-4 and API FA-4 could be used for highway trucks.
FA-4 oils were developed as a means of meeting goals to reduce greenhouse gas emissions, and improve fuel economy. API FA-4 standards provide low-viscosity oils, which reduce fuel economy by not requiring vehicles to use as much energy to circulate the oil throughout the engine while still protecting vehicle engines from wear.
Alternatively, API CK-4 oils were developed to solve the problem of off-road vehicles which had engines that reached extremely high temperatures. API CK-4 oils offer the same performance improvements as FA-4 oils; however, since the off-road market doesn’t place as much importance on fuel economy, CK-4 oils come in a wider range of viscosities in order to ensure engine protection in off-road vehicles.
Also, it should be noted that, currently, FA-4 oils are not recommended for use in off-road vehicles. While FA-4 offer fantastic environmental benefits, the low-viscosity nature of this type of oil may not offer sufficient protection when faced with the extreme temperatures present in the engines of off-road vehicles.
Automotive vehicle owners may assume diesel oil is superior to gas engine oil for a variety of reasons.
First of all, diesel oils are often marketed as “heavy-duty” or “max-duty” due to the fact that they are counted on to protect the hard-working engines found in trucks and off-road vehicles. This leads consumers to view them as better choices for their vehicles than gasoline engine oils.
Moreover, diesel oils often have better detergent additives. These additives help to cleanse oil impurities. Without these additives, oil can deposit these impurities onto vital engine parts, which can cause severe damage to engine components.
In some cases, Amsoil diesel oil can be more beneficial to use in place of Amsoil synthetic oil for gasoline engines. For instance, if your engine is modified to put out an extreme amount of horsepower, it can be beneficial to use a high-viscosity Amsoil diesel oil to protect your engine from wear. However, if you have a vehicle with its stock gasoline-powered engine, it may be best to use gasoline motor oil. Either way, there is an extensive list of Amsoil products to choose from.
Is it Safe to Use Diesel Oils in Gas Engines?
Maybe you already have some diesel oil that you don’t want to waste, or you would feel more comfortable using a high-viscosity oil for engine protection purposes. If this is the case, you might be wondering if it is okay to use diesel oil in your gasoline engine.
One factor to consider is that diesel engine oils often contain additional additives such as detergents and anti-foaming agents, and have much higher SAE ratings – things that aren’t necessary to have in oils for regular gas engines.
Additionally, due to the higher compression ratios found in diesel engines compared to gas engines, diesel oils have to have additional detergents added to them in order to combat combustion byproducts found in diesel engines.
Due to these factors, it may seem like diesel engine oils would not be safe to use in gasoline-powered engines. However, many Amsoil products are made to comply with the needs of gasoline and diesel engines. As a result, it is generally safe to use diesel oils in your gasoline-powered engine.
However, if you choose to go this route, it is vital that you make sure that the diesel oil you choose meets the viscosity and specification requirements of your vehicle’s engine. For example, if your vehicle’s owner’s manual indicates that your engine needs a 5W-30 oil that meets API SN guidelines, you must use a diesel oil that also meets these specifications. Amsoil oils will list these specifications on any oil’s product page. For instance, if you look at the product page for Amsoil Signature Series Max-Duty Synthetic Diesel Oil 5W-30, it says at the bottom of the page that it meets the specifications for API SN.
In short, while it is probably better to use oil specifically manufactured for gasoline-powered engines, it is generally safe, and sometimes beneficial, to use diesel engine oils in your gas-powered vehicle.
