Who Makes the Best Synthetic Oil for Heavy Equipment Maintenance?

As an owner/operator of a heavy equipment fleet operation, the subject might have come up at various times as to who makes the best synthetic oil for heavy equipment maintenance. In this blog post, we’ll try to answer that question and hopefully give you some food for thought in terms of how your lubricants stack up to some of our suggestions.

First, let’s discuss what exactly heavy equipment maintenance is.

Creating a proper and proactive heavy equipment maintenance and repair program is critical to keep your operation humming along. When that dreaded unexpected downtime rears its evil head for a critical piece of equipment, customers become frustrated. Projects are delayed and profits are impacted negatively. Once a piece of heavy equipment is down, the operation must quickly find a solution to get that piece of equipment back up and running. It’s difficult to run a bulldozer down the road to an outside maintenance shop, so it makes sense to create a strategy for having the capability to repair your equipment yourself and keep it in-house.

What is Involved in Heavy Equipment Maintenance?

Heavy equipment maintenance is a systematic approach to regularly checking, repairing, and cleaning a multitude of heavy machinery components that includes engine, hydraulics, and other critical moving parts.

There are two approaches to maintaining heavy equipment. It can be a preventative/proactive maintenance program. Establishing a preventative maintenance program means that your heavy equipment follows a specific schedule that involves religiously checking and changing oil, checking tire pressures, and regularly cleaning the equipment.

The other approach is having a reactive maintenance program. This means when a piece of equipment has a failure or is not running properly, your mechanic must react and try to fix the problem in the field. A reactive maintenance approach will tend to increase downtime, wasted money, and time. Deciding to establish a rigorous preventative maintenance program is the preferred strategy if the goal is to minimize or reduce downtime incidents and to lower or control maintenance and repair costs.

It can logically be established that creating and executing a proper preventative maintenance program is the proper strategy that is not only extending the life of your equipment but keeping them running at maximum efficiency and helping you stay ahead of schedule, thus saving money.

Why is a Proper Heavy Equipment Maintenance Program Essential?

You can make a real positive impact on your business by establishing a proper maintenance program for your heavy equipment. Choosing to continuously have a reactive approach to heavy equipment repair can be costly and cause an inordinate amount of downtime. Choosing not to be proactive in your maintenance program can negatively affect your company’s bottom line and reduce profits. Having only one piece of equipment down in the shop for unexpected repairs for too long of a time can cause a major negative effect not only on the project and schedule but also on your customer, due to delays.

By deciding to change your company’s philosophy towards a proactive maintenance program can vastly lessen the chances of downtime and save your operation a huge amount of money and keep your clients happy. One specific area that can have a hugely positive effect on your maintenance program is understanding and choosing to use the best possible lubricants. With that in mind, the obvious question is who makes the best synthetic oil for heavy equipment maintenance?

To understand the answer to that question, we first need to analyze the differences between conventional lubricants vs 100% synthetic lubricants.

Synthetic vs Conventional Lubricants

Regular or conventional oils are derived from crude oil to have a mineral base stock oil that can be used in the manufacturing of a lubricant for heavy equipment requires the crude oil to be put through a series of complex refining processes. The goal is to refine and extract out as many contaminants that are naturally found within crude oil. These contaminating elements that are typically found in crude oil are nitrogen, sulfur, oxygen, and metal components such as vanadium or nickel.

These contaminants simply cannot be 100% removed during this refining process. Once all the refining processes have finished, what’s left behind is an oil with a molecular structure that is dissimilar. In other words, regular or conventional lubricants are made up of molecules that are different in size, thus making such oils offer inferior performance. Due to the different sized molecules, these molecules struggle to flow over each other easily and smoothly. This fluid friction causes the oil to flow slower and creates unwanted heat/rising temperatures.

Another impurity that is found in conventional oil is wax. As temperatures drop and become cold, the wax causes the oil to thicken and flow with even more resistance during cold temperatures. This is especially a negative issue when starting a piece of heavy equipment that has been sitting idle. It has been stated by many original equipment manufacturers that 80% of wear occurs during cold, dry startups. It stands to reason that to reduce this inordinate amount of wear during cold dry starts requires a lubricant that flows well in cold temperatures and gets to critical components as quickly as possible. Unfortunately, conventional oils are poor at that.

Synthetic lubricants are manmade and chemically designed to create lubricants that are pure. There are no unwanted contaminants in the synthetic base stock oils and these oils have been specifically engineered to not have any of the negative aspects found in conventional base stock oils. Not only are they devoid of any unwanted contaminants, but they are also engineered with a uniform or same-sized molecular structure. They have been specifically engineered to offer only the best features and qualities that are necessary for providing maximum lubrication and protection to componentns. 100% pure synthetic oils deliver superior friction reduction, durable film strength, outstanding temperature performance over a broad range of temps, and enhanced fuel economy efficiency.

Because synthetic base stock oils do not contain wax, they are the perfect lubricant for cold dry startups. They do not thicken up when exposed to cold temperatures, they flow freely and quickly to immediately provide lubrication to critical components in heavy machinery, and they can vastly reduce any wear that occurs during cold dry startups.

Years of third-party testing and in-field performance have proven that hands down, synthetic lubricants outperform conventional lubricants in all critical areas.
