An oil change is the one job where ramps are clearly the better tool. You need access to the drain plug and the oil filter, both of which are under the front of the car, and you never need a wheel off. No jack, no stands, no load transfer — drive up and start.
How much height do you actually need
Less than people assume, and it depends entirely on where your filter is. Two cases:
- Drain plug only (cartridge filter on top of the engine). You need enough room to get a wrench on the plug and a pan underneath. Two to three inches of lift is often enough on a car with reasonable stock clearance.
- Spin-on filter underneath. You need room for your arms, a filter wrench and a pan positioned to catch what runs out of the filter housing. This is where 6-8 in of lift earns its money.
Check which your car has before you buy ramps. Open the hood: if there is a black plastic cap on top of the engine with a filter element under it, you have a cartridge filter and your clearance needs are modest.
The drain pan is a real constraint
A low-profile drain pan needs less clearance than a bucket, which changes the math on how much lift you need. Measure your pan's height and add it to the space you need for your hands. A pan that will not fit under the sump with the car on ramps is the most annoying way to discover you needed more lift.
The first oil change tool list covers the pan, the filter wrench, and the parts people forget — including the crush washer for the drain plug.
Ramps make the oil level question awkward
A car on ramps is nose-up, which means the oil in the sump is not sitting where the dipstick expects it. Do not check or set the final oil level on the ramps. Fill to slightly under the specified capacity, back the car down onto level ground, let it settle for a few minutes, and then check and top up.
This also affects draining: a nose-up car drains slightly less completely than a level one. It is a small difference and not worth worrying about — but it is the reason some people prefer a jack and stands for oil changes despite the extra work.
The short version of the procedure
1.Warm the engine briefly, then let it stand
Two or three minutes, then ten to cool. Warm oil flows; hot oil scalds.
2.Drive onto the ramps, secure the car, chock a rear wheel
Straight approach, steady speed, stop when the tire reaches the flat. See how to use car ramps.
3.Position the pan, then loosen the drain plug
The pan goes where the oil will land, which is not always directly below the plug.
4.Drain, change the filter, fit a new crush washer
The washer is a consumable and re-using it is the usual cause of a weeping plug.
5.Refill short, come down, check on level ground
Then top up to the mark with the car level and the engine off.
