Grease vs Oil: Which is the better industrial lubricant?

Choosing the correct lubricants can be a difficult task, but it need not be complicated. The purpose of a lubricant is to reduce the friction on the moving parts of machinery, thus improving its performance and longevity. Lubricants come in two basic categories, oil and grease. Each has their strengths and weaknesses and which you choose depends on your application. A debate still goes on as to which is better.

Oil is typically 95% mineral based with 5% additives. Synthetics exist as well and one must also consider the grade of viscosity when choosing a lubricant, but it does tend to be more liquid than grease. Grease, on the other hand is basically oil thickened with soap. It is used typically in applications where fluid lubricants are too difficult or cannot be retained. In choosing an appropriate lubricant one must look at the pros and cons of each.

The advantages of grease is that it has a better start up performance because it doesn’t drain into the sump, it acts as a sealant and is less prone to leakage. Grease uses solid additives such as graphite, zinc oxide or molybdenum disulphide which may settle or become filtered in many oils. Oil, on the other hand, flows freely, enabling it to carry away unwanted heat. Oil doesn’t use thickeners, thus eliminating the danger of clashing incompatible thickeners, causing a change in consistency.

Contaminants in oil such as water or dirt are suspended briefly before being transported to filters and settling zones whereas grease can retain contaminants indefinitely. Oil is easier to change than grease as the machine does not have to be dismantled to do so. Removal of grease requires a complete purge. Disposing of oil is much more environmentally friendly than grease which is a total-loss proposition. There is no environmentally friendly way to dispose of grease.

Oil lubricants tend to have a higher rating than grease and are the typically the preferred industrial solution. However, each has its own merits. Grease is preferred because it is stable, suitable for any housing orientation, easy to transport, can withstand higher rotational forces and performs better at slow speeds. Oil is preferred because it is widely available, has excellent flow properties, even temperature gradients, and allows wear particles to settle so the lube is “fresh” during operation.

Monolec Industrial Lubricant: A Review

Using the proper oil for your engine means the difference in a smoothly running machine, whether it’s a car, boat, or piece of equipment. Oil is the material that keeps metal parts from grinding together and wearing down, and can also prevent dirt buildup in a piece of machinery.

Choosing lube oil can be a difficult task, as not only do lubricant oils come in various forms and varieties, but different industries and sectors have their own standards and regulations. Because of this, it is crucial that the right choice of lubricant is chosen for the right application.

Monolec is an exclusive, wear reducing additive which creates a lubricating film on metal surfaces, which increases the strength of the oil used. Using Monolec will allow opposing surfaces to glide by one another greatly reducing heat, friction and wear.

Monolec Industrial Lubricants are designed specifically for use in centralized lubrication systems. They contain both wear reducing and extreme pressure additives, are waterproof, and will not form permanent emulsions when moisture is present. They also contain special additives for rust prevention.

Users of Monolec Industrial Lubricants say that it is their secret to keeping their machines moving and also keeps the machines on good condition well after their shelf life. “This oil keeps the gears moving and also reduces oil consumption which saves me money”, says Albert B., one reviewer.

The base oil and additive formula are designed to work together. Clive G. says, “After one oil change I could see no sludge formation or deposits, which is unheard of in my experience.”

Monolec Industrial Oil meets or exceeds the requirements hydraulic systems, gear boxes, roll mill bearings, air compressors and vacuum pumps found in industries such as paper, plastic, rubber and textiles.

For many decades, suppliers of lubricants have been designed and formulating lubricants tailored to industrial application requirements. All lubricant oil should meet the technical requirements for dissipating heat, protection against corrosion and reducing wear and friction. However, it depends on the manufacturing processes and operating conditions specific to your industrial plant which could mean that the right lubricant for the job should produce a whole host of additional properties. As a result of so many variables, it is just as important to choose the right lubricant manufacturer as it is the right lubricant. Do your research before purchasing any lubricants, including talking to your equipment manufacturer for the best recommendations.
