What ramps do and why they're safer than jacks

Car ramps are angled metal or plastic platforms you drive onto to lift the front or rear of your vehicle high enough to work underneath. Unlike a hydraulic jack, which holds your car up by force alone, ramps support the weight of your vehicle across their entire surface — the same way a bridge does. This distributed support makes ramps one of the safest ways to get under a car for an oil change, especially if you're working alone.

Ramps come in pairs and typically cost between $30 and $150 depending on weight capacity and material. A standard set handles vehicles up to 12,000 pounds, which covers most sedans, small SUVs, and trucks. The main trade-off is that ramps only lift the front of your car (or rear, depending on which end you drive onto), so you'll need a different approach if your drain plug is in an awkward spot.

Key Takeaways

  • Ramps support your car's weight across their full surface, making them safer than relying on a jack alone for an oil change.
  • You need to drive straight onto the ramps in a controlled way, then chock the rear wheels with blocks or wedges to prevent rolling.
  • Check your owner's manual or the ramp packaging to confirm your vehicle's weight is within the ramp's rated capacity.
  • The entire process — positioning, securing, draining, and replacing the filter — typically takes 30 to 45 minutes once you're comfortable with the setup.

Choosing ramps that match your vehicle

Before you buy or borrow ramps, verify that they can handle your car's weight. The weight capacity is printed on the ramps themselves or on the packaging. If you own a sedan, most standard ramps work fine. Heavier vehicles — full-size trucks, large SUVs, or vehicles over 5,000 pounds — need ramps rated for at least 12,000 pounds total (6,000 per ramp).

Ramps also come in different heights. Low-profile ramps (4 to 6 inches) work for most cars but may not give you enough clearance if your vehicle sits close to the ground or if your drain plug is recessed. Taller ramps (8 to 12 inches) provide more working room but require a longer, more gradual drive-on. Check your vehicle's ground clearance and the location of your drain plug before deciding.

Material matters too. Plastic ramps are lighter and cheaper but can crack under extreme weight or in cold weather. Metal ramps are heavier, more durable, and better for repeated use. If you plan to change your own oil regularly, metal ramps are the better investment.

Setting up ramps safely

Position both ramps on level, solid ground — concrete or asphalt, not gravel or dirt. Align them so they point straight ahead, parallel to each other, and spaced to match your vehicle's tire width. The ramps should be close enough that your tires land squarely on them, not teetering on the edges.

Put your vehicle in neutral and slowly drive forward onto the ramps. Go straight and at a walking pace. Stop when your vehicle is centered on the ramps and the front wheels are roughly in the middle of each ramp's surface. Do not drive too far forward — you want the ramps to support the engine and frame, not just the front axle.

Once the front wheels are on the ramps, shift into Park and engage the parking brake. This is critical. Then place wheel chocks (wooden blocks, rubber wedges, or purpose-made chocks) behind the rear wheels to prevent the vehicle from rolling backward. Chocks should be snug against the tire but not wedged so hard that they're difficult to remove later.

Working safely under the vehicle

Before you crawl under, give the ramps a visual check. Make sure the vehicle is not rocking or shifting. If it feels unstable, drive off carefully and reposition. Never work under a vehicle supported only by ramps if you're not confident it's find.

Wear safety glasses and work gloves. The oil will be warm (though ideally not scalding hot — let the engine cool for a few minutes after running). Locate your drain plug, position a drain pan underneath, and unscrew the plug by hand or with a wrench. Let the old oil drain completely, which usually takes 5 to 10 minutes.

While the oil drains, locate your oil filter. It's typically a cylindrical canister on the side of the engine. Use an oil filter wrench to loosen it, then unscrew it by hand. Wipe the filter mounting surface clean with a rag, then hand-tighten the new filter until the rubber gasket contacts the engine, then turn it another three-quarters of a turn. Do not over-tighten.

Wipe the drain plug clean, reinstall it, and tighten it snugly — not with all your strength, just firm. Replace the oil filler cap on top of the engine, then carefully back your vehicle off the ramps at a slow, controlled speed. Once the front wheels are on level ground, shift into Park and remove the wheel chocks.

Checking your work before driving

Start the engine and let it run for 30 seconds. The oil pressure light should come on briefly, then turn off as oil circulates. If the light stays on, turn off the engine when ready and check your drain plug and filter for leaks. A small drip is normal; a steady stream means something is loose.

Turn off the engine and wait two minutes for the oil to settle. Pull the dipstick, wipe it clean, reinsert it fully, then pull it again to check the level. The oil should be between the minimum and maximum marks. If it's low, add a small amount of the same oil you just put in, then recheck.

Dispose of the old oil properly. Most auto parts stores and service stations accept used oil for free or a small fee. Never pour it down a drain or into the ground.

When ramps aren't the right choice

Ramps work best for front-engine vehicles with drain plugs on the underside of the engine. If your drain plug is on the side of the pan or in a spot that's hard to reach even when the front is elevated, you may need a different setup. Some vehicles with very low ground clearance or unusual drain plug locations are easier to service with a floor jack and jack stands, though this requires more caution.

Ramps also don't work if you need to access the rear of the vehicle — for example, if your drain plug is at the back. In that case, you'd need to drive the rear wheels onto the ramps instead, or use a different lifting method altogether.

Frequently Asked Questions

Can I use ramps on a sloped driveway?

No. Ramps must be on level ground. A slope changes how weight distributes across the ramps and can cause your vehicle to shift. If your driveway slopes, find a flat spot nearby — a parking lot, a level section of your street, or a friend's driveway.

How do I know if my ramps are rated high enough for my car?

Check the weight capacity printed on the ramps or their packaging. Look up your vehicle's curb weight in your owner's manual or online. The ramps' total capacity should be at least equal to your vehicle's weight, though having extra capacity is safer. When in doubt, ask at an auto parts store.

What if I only have one set of ramps but need to lift both the front and rear?

You can't do both at the same time with one set. Change the oil from the front, then if you need to access the rear for another job, drive off the ramps, reposition them at the back, and drive on again. Never try to lift both ends simultaneously without proper equipment.

Do I need to use jack stands with ramps?

No. Ramps are designed to be a standalone support system. Jack stands are used with jacks as a backup safety measure. If you're using ramps correctly — with wheel chocks in place and the vehicle centered — you don't need additional support.

Can I leave my car on ramps overnight?

It's not recommended. Ramps are meant for temporary work, not extended storage. Leaving your vehicle on ramps for hours or days can stress the ramps, damage your tires, and create a safety hazard if someone forgets the car is elevated. Use ramps only while you're actively working underneath.
