Oil changes continue to be one of the most common DIY repairs performed on vehicles today. According to a recent Counterman P.A.R.T.S. report, changing the engine oil was the second-most popular DIY auto care job, behind only changing the wiper blades.
Changing the oil and filter is right in the sweet spot for do-it-yourself (DIY) vehicle owners: It’s a regular maintenance task that’s critical to the overall health and longevity of the engine, and it’s easy to perform. It’s the sort of basic maintenance that can be performed by someone who might not get their hands dirty otherwise. Chances are you’ve had a DIYer in your store asking how to get started. Let’s talk about some of the tips you can share with your DIY customers to help them change their own oil – and do it right.
Essential Tools vs. Non-Essential Tools
Tools are a long-term investment. They may cost more than they’ll save on the first oil change, but they pay for themselves in the long run!
Let’s start with the essential tools that every DIYer should have in their garage. At the top of this list, we find a jack and jack stands. Whenever you’re working underneath a vehicle, you need to make sure that it’s lifted up on level ground, and that it’s safely supported with jack stands. If you lift the vehicle up with a hydraulic jack, and don’t support it with jack stands, the jack can lose pressure and the vehicle will start to lower itself. If you’re underneath the vehicle when this happens, it can be deadly. Be safe, be smart and live to wrench another day. If any of the wheels are coming off, I place them underneath the vehicle for an added layer of protection. My thinking is simple: If something went wrong, having to replace a wheel and/or tire could be the least of my problems!
As a personal rule, I like to use jack stands that are rated for far more weight than I’ll ever put onto them. I have a number of 4-ton and 6-ton jack stands, and I prefer them over the less expensive 2-ton stands due to their increased footprint, and more robust construction.

You’ll also need some form of tool to remove the oil filter or filter housing cap (Figure 1). It’s worth mentioning that you may need to purchase specialty tools to remove the drain plug or filter housing on certain applications. For example, Volkswagen uses a proprietary tool to remove the plastic drain plugs from its modern four-cylinder engines. GM Ecotec engines require a special socket to remove the filter housing cap on its 1.4T and 1.8-liter four-cylinder engines. These are only two examples of many, so it’s best to do some online research before starting the job. Make sure you have all the tools you need on hand BEFORE you start to drain the oil.
You’ll need some form of drain pan or container to catch the oil as it drains out of the engine. It’s a good idea to have some old rags or towels on hand to clean up any spills or messes along the way, and I usually have a can of brake cleaner for added cleaning “umph.”
Finally, let’s talk about personal protective equipment (PPE). It’s a good idea to wear safety glasses to protect your eyes, and gloves to protect your skin.
Tips & Tricks
First and foremost, a DIY customer probably will have a lot of questions about what type of oil they need, how much oil their engine holds and more. While you may be able to lookup fluid specifications and capacities in your catalog, your DIY customers won’t have access to something like that. But a quick Google search should get them on the right track. I would always advise them to follow the OE maintenance guide and specifications, regardless of mileage or age.
There are a lot of things that you’ll learn through experience. Any tips, pointers or advice you can share with your DIY customers can go a long way toward helping them, and might just be the thing that gets them back to your store for the next repair. For example, some oil-drain plugs feature a gasket or crush washer that seals up against the oil pan. This type of gasket will need to be replaced at every oil change. A leaky drain plug can be a real pain, and could be really discouraging to a DIYer after their first oil change.
Then there are the little things that just make the whole job go a little bit smoother. I like to keep some old, cut-up cardboard boxes around the garage. In a pinch, they work great as a “poor man’s creeper.” Sometimes you don’t have enough room under the vehicle to slide around on a creeper, so the cardboard gives me something to lay on without having to lay directly on the cold, concrete floor.
When replacing a spin-on oil filters, always wipe off the mounting surface before installing the new filter. This ensures that any dirt or debris will be wiped away, AND if the gasket was stuck in place, you’ll either feel it, or you’ll knock it off of there. If you installed the new oil filter on top of the old gasket, it wouldn’t seal correctly. The result would be a massive blowout, leaving oil all over the garage floor. Not a great way to spend an afternoon!

This cap will contain one or more O-rings that seal inside the housing. These O-rings need to be replaced with every oil change, and they’re almost always included with the new cartridge oil filter. Whatever you do, don’t double up these O-rings! This can lead to massive oil leaks, but it also can make the filter housing cap nearly impossible to remove (Figure 2).
Finally, always dispose of the used oil safely. If your store will take used oil, be sure to let your customers know. If your store cannot take in used oil, make a list of nearby shops that will. Some shops use oil-burning heaters, so they may take used oil without a charge to the customer.

Filters trap contaminants and protect vital components downstream. Replacing filters on a regular basis is one of the most important things your customers can do to prolong the life of their vehicles.
Oil filters trap dirt and other particles that could lead to premature wear on the bearings, rings and other internal engine surfaces. Air filters trap dirt and debris to protect the piston rings and cylinders. Cabin air filters help to prevent dust, pollen and other odor-causing contaminants from entering the vehicle cabin. Finally, the transmission filter prevents debris from jamming control valves and hydraulic passageways, and helps to prevent premature wear inside the transmission.
Fuel filters also have an important job, but they’ve grown more and more uncommon in recent years. It’s not that fuel filters have gone away. They’ve simply been phased out in favor of better filtration at the fuel-pump module inside the fuel tank (also known as the “sock”).
There’s one more filter that only recently has come into the market: the battery-compartment filter. This filter can be found in many hybrid and electric vehicles on the road today. It’s responsible for filtering the air that’s flowing into the battery compartment for cooling purposes. It has a replacement interval just like any other filter.
Modern Media
Filters use all sorts of different media inside to trap contaminants. This may be resin-impregnated cellulose fibers, synthetic fibers (glass and polyester) or more commonly, a composite mixture of natural and synthetic fibers. The bottom line is that there’s a lot of clever engineering that goes into finding just the right balance between efficient filtering, dirt-holding capacity and overall flow.
Standard air filters use pleats to trap airborne contaminants as they pass through the element. The deeper the pleats are, the more surface area the filter use to trap those contaminants. Once light is unable to pass through the air filter, it’s probably time to replace it. This method may not work well with certain filter media, so it’s still best to always follow the OE maintenance schedule for the particular application.
Some customers may be interested in engine air filters that offer improved air flow and performance. This type of filter element is typically a cotton weave that’s held in place by some sort of mesh material. The weave is looser than a traditional air-filter media, allowing a greater volume of air to pass through. Since this type of media wouldn’t be able to filter out smaller particles like a standard air filter could, it’s coated with a light oil that will aid in trapping those particles. That oil coating will contain a coloring dye, and they will need to be cleaned and re-oiled periodically. I would suggest warning your customers to be careful to not over-oil the filter during that process.
Selling the Right Filter
When you’re selling an oil filter, consider the price point, service life and ease of installation. Extended-life oil filters are a great option for vehicles with long oil-change intervals. My 2019 VW Golf Alltrack has an interval of 12 months or 10,000 miles. It’s very important to only use oil filters that are rated to go for that long before being replaced.
Some oil filters may contain a gel or wafer that slowly dissolves over time. This process releases chemicals that help to maintain oil viscosity and neutralize sludge-forming acids. Some premium spin-on oil filters utilize an internally lubricated seal. This simple addition makes a big difference when it comes time to remove the filter during the next oil change. If you’ve ever tried to remove an oil filter that felt like it had been welded into place by “the last guy,” you know why this is a big deal.
Premium cabin air filters may use activated carbon to aid in trapping odors and smaller airborne contaminants. Your customer may be interested in a premium cabin air filter if they, or someone in their family, have a severe allergy, asthma, bronchitis or another respiratory concern. Some premium filters include an antimicrobial coating that helps to prevent the growth of bacteria and mold, as well as trap airborne virus aerosols. So, how small are we talking? Pollen is easy to filter, ranging from 10 to 100 microns in diameter. Mold and spores can range from 3 to 80 microns in diameter. Viruses are much smaller and can only be seen with a high-power microscope. They can range in size from .005 to .3 microns. However, it’s unlikely for viruses to “fly solo.” They’re usually carried through the air in liquid aerosol droplets, typically around 3 microns in diameter. All of these contaminants can be trapped using the right filter.
