Automotive Fluids

You've Got Vehicles to Maintain. We'll Help You Keep Them Supplied.

Oil changes. Coolant replacements. Transmission service. Routine fleet maintenance.

When you’re responsible for keeping multiple vehicles running, there’s always something that needs attention.

And whether you’re managing a fleet of delivery vans, maintaining municipal vehicles, or servicing trucks in a repair shop, you need the right automotive fluids available when it’s time to do the work.

You probably already know what your vehicles take.

The question is where you’re going to get it.

At Comet Supply, we provide automotive lubricants and fluids for commercial fleets, repair shops, municipalities, trucking companies, and other businesses that maintain multiple vehicles.

From bulk motor oil and antifreeze to transmission fluids, gear lubricants, and windshield washer fluid, we help customers find the products they need in quantities that make sense for their operations.

And when you need an equivalent product, have questions about a specification, or aren’t sure what a particular vehicle requires, we’re here to help with that, too.

Automotive Lubricants & Fluids for Commercial Fleets

Different vehicles have different maintenance requirements, and the products you need depend on what’s in your fleet.

Comet supplies a range of automotive fluids from established manufacturers, along with our own gear lubricants.

  • Bulk Motor Oil & Heavy-Duty Engine Oils

    Engine oil is one of the products fleet maintenance departments and repair shops go through regularly.

    Comet supplies bulk motor oil for commercial maintenance operations, including products for passenger vehicles, light-duty trucks, and heavy-duty applications.

    We work with customers to source the oils they already use, compare product specifications, and find suitable alternatives when needed.

  • Bulk Antifreeze & Automotive Coolants

    The right coolant matters year-round, not just when temperatures drop.

    Comet supplies bulk antifreeze and automotive coolants, including conventional and extended-life formulations for different vehicle requirements.

    And with so many coolant types available, compatibility is important. Different formulations aren’t necessarily interchangeable, and color alone doesn’t tell you whether two products can be safely mixed.

  • Automatic Transmission Fluids

    Transmission fluid is one place where getting the specification wrong can become an expensive mistake.

    Comet distributes bulk transmission fluid and automatic transmission fluids for commercial maintenance operations, including products meeting various DEXRON and MERCON specifications.

    We can help cross-reference an existing ATF and verify the applicable requirements before recommending an alternative.

  • Automotive Gear Oils

    Comet doesn’t just distribute automotive lubricants. We also manufacture our own gear oils.

    Our Gearlube 5 products are designed for automotive and heavy-duty gear applications, including trucks, passenger vehicles, agricultural machinery, and construction equipment.

    Available in SAE 80W-90 and 85W-140, Gearlube 5 is formulated to meet API GL-5 and MT-1 classifications, providing extreme-pressure protection for heavily loaded components.

  • Bulk Windshield Washer Fluid

    Windshield washer fluid is another product fleets and repair shops need to keep on hand.

    Comet supplies bulk windshield washer fluid, including winter formulations with de-icing capabilities.

    Whether you’re preparing for colder weather or stocking up for routine maintenance, we can help you source washer fluid in quantities appropriate for your operation.

  • Automotive Greases & Vehicle Care Products

    Comet also offers greases for applicable steering and other vehicle components, along with automotive cleaning and care products.

    Through Spartan’s vehicle-care line, we can supply washes, waxes, and related products for commercial vehicle cleaning and maintenance.

Know What You Need? We’ll Help You Find It.

You know what goes into your vehicles. You’ve probably been ordering some of the same products for years.

But every now and then, something changes.

A product becomes unavailable. A new vehicle joins the fleet. Or you need to know whether a different formulation will do the job.

That’s when Comet’s product knowledge comes in. We’ll help you research the requirements, compare your options, and find an appropriate match.

Because not every automotive fluid is interchangeable.

Different transmissions can require very specific ATF formulations. Coolants can have different chemistries that aren’t necessarily compatible. And a familiar brand name, similar viscosity, or matching coolant color doesn’t guarantee that a product meets the requirements.

We want to make sure what you’re putting into the vehicle is appropriate for the equipment.

Automotive Fluids for the Way Your Fleet Operates

A truck that spends most of its time on the highway operates differently from a delivery van making frequent stops around town.

A municipal fleet might include passenger vehicles, service trucks, and other equipment, each with its own requirements.

And seasonal conditions matter, too.

Comet works with trucking companies, municipal maintenance departments, repair shops, dealerships, delivery services, towing operations, agricultural businesses, and other commercial customers.

Whether you’re maintaining one type of vehicle or an entire mixed fleet, we can help you source the fluids that meet your equipment’s requirements.

A Supplier You Can Work With for the Long Haul

Some of our commercial and municipal customers have been working with us for more than a decade.

And we understand that the best supplier relationship isn’t necessarily the one that involves the most complicated solution.

Sometimes you just need to reorder what you’ve been using for years.

Sometimes you have a question that takes a little digging.

Either way, you shouldn’t have to jump through hoops to get an answer.

We want to be the people you can call, explain what you’re looking for, and know we’ll make an effort to help.
