Changing your own oil can be a satisfying way to save money and stay connected to your car. For many enthusiasts, it is almost a ritual—a simple job that keeps the engine healthy. But not every car makes this easy. Some designs bury the oil filter in awkward spots, require removing half the engine bay plastics, or even use special tools that make you regret picking up a wrench. According to owners who have been through the struggle, these eight cars are among the worst choices if you like to handle oil changes yourself.
BMW 3 Series (Modern Models)
BMW’s legendary 3 Series is a driver’s car, but DIY maintenance is another story. On many recent models, the oil filter is tucked deep inside the engine bay under plastic covers that need to be removed carefully. Owners often complain about messy oil draining because the filter housing leaks as soon as it is loosened. Add in special filter caps and torque requirements, and a simple oil change can feel like a weekend project.
Audi A4 and Other Turbo Models
Audi is known for engineering excellence, but simplicity for the home mechanic is not part of the design brief. On many A4s, especially turbocharged models, the oil filter is hidden behind hoses or tucked down near the exhaust. Accessing it often requires removing panels from underneath, which means jacking the car up safely and crawling under it. Owners report that one missed step can lead to spills all over the subframe.
Mini Cooper
The Mini Cooper may look small and friendly, but it is not DIY friendly when it comes to oil changes. The oil filter is mounted vertically in cramped space, and reaching it often requires moving components around. Some owners even say you need a special socket to fit the filter cap properly. The drain plug is also recessed, making it tricky to get to without the right setup. What should be a quick job turns into an exercise in patience.
Chevrolet Camaro (V6 and V8 Models)
You would think American muscle cars would be straightforward, but Camaro owners know better. On both V6 and V8 models, the oil filter is located in awkward spots that make spills almost guaranteed. On some, you need to maneuver the filter around crossmembers and suspension parts, leaving oil dripping on everything. Without a lift, it is tough to get good access, and owners often joke that a shop rag is as important as the wrench.
Subaru WRX and WRX STI
Subaru’s rally inspired sedans are loved by enthusiasts, but their oil filter placement is one of the most baffling in the industry. Subaru mounts the filter directly on top of the engine, which seems convenient until you actually use it. Removing the filter often sends oil spilling over belts and other engine parts. Add in the tight space around the drain plug, and owners quickly learn why many WRX drivers let shops handle this chore.
Mercedes Benz C Class
Luxury and DIY maintenance rarely go together, and the Mercedes C Class is no exception. The oil filter housing sits under covers that require removal, and access is cramped. On some models, owners report that even with the right tools, the design makes spills unavoidable. The drain plug may also require a Torx or special bit, which adds to the frustration if you do not already have a well stocked toolbox.
Ford Mustang GT (Coyote V8)
The Mustang GT’s Coyote V8 is a masterpiece of performance, but it is not designed with home oil changers in mind. The filter is buried in a spot that almost guarantees oil pouring over your hands and suspension components when it is removed. Some owners suggest using makeshift funnels just to control the mess. While not impossible, it is far messier than most would expect from a car with such a strong DIY following.
Dodge Charger and Challenger (Hemi V8)
Mopar muscle is known for big power, but oil changes are not always simple. On modern Hemi powered Chargers and Challengers, the filter sits in awkward positions that make removal messy, and the underbody shields often require extra steps to access the drain plug. Owners complain that unless you have a lift and a lot of rags, you will spend as much time cleaning up oil as you do replacing it.
