RAM oil changes follow the same basic steps as most trucks, but RAM models vary in engine size, oil capacity, and filter location

A RAM oil change means draining the old oil from your engine, replacing the oil filter, and refilling with fresh oil at the capacity and grade your specific model requires. The process takes 30 to 45 minutes for most owners and costs between $40 and $80 in materials if you do it yourself. RAM trucks — whether a RAM 1500, 2500, or 3500 — have different oil capacities and filter positions depending on the year and engine type, so checking your owner's manual before you start is essential.

The most common mistake is using the wrong oil grade or overfilling the pan. RAM publishes the correct oil type and capacity for each model year in the owner's manual, usually in a table near the maintenance schedule. Using thicker or thinner oil than specified can affect engine performance and fuel economy. Overfilling by even half a quart can cause the oil to foam inside the engine, reducing its ability to protect moving parts.

Key Takeaways

  • Your RAM's oil capacity and recommended grade are printed in the owner's manual and vary by engine size and model year — check before you buy oil.
  • The oil drain plug is on the underside of the engine pan, and the filter location depends on your engine type; RAM 1500s often have the filter on top, while 2500 and 3500 models may have it mounted to the side or underneath.
  • You will need an oil drain pan, a wrench or socket for the drain plug, an oil filter wrench, and a jack and jack stands if you need clearance to reach the drain plug or filter.
  • Dispose of old oil at a recycling center, auto parts store, or service station — never pour it down a drain or into the ground.

What you need before you start

Gather your tools and materials in one place. You will need a wrench or socket set to remove the drain plug (usually 13mm, 14mm, or 15mm depending on your RAM model year), an oil filter wrench to unscrew the old filter, a new oil filter that matches your engine, fresh oil in the correct grade and quantity, and an oil drain pan to catch the old oil.

If your RAM sits low to the ground or the drain plug is hard to reach, you may need a jack and jack stands to lift the truck safely. Never work under a vehicle supported only by a jack. If you do not own a jack and stands, use ramps instead — drive the front wheels onto the ramps and set the parking brake. Check your owner's manual for the correct jacking points on your specific model.

Warm the engine for two to three minutes before draining. Warm oil flows faster and carries more debris out of the pan. Let it cool for one minute so you do not burn yourself, then proceed.

Draining the old oil and replacing the filter

Locate the oil drain plug on the underside of the engine oil pan — it is usually a bolt with a hex head. Place the drain pan underneath it, then use your wrench to turn the plug counterclockwise. Once it is loose enough to turn by hand, unscrew it the rest of the way and let the oil drain completely into the pan. This can take five to ten minutes. Wipe the drain plug clean with a rag and inspect the rubber washer; if it is cracked or flattened, replace it with a new one before reinstalling.

Screw the drain plug back in by hand first, then tighten it with your wrench. Do not over-tighten — snug is enough. A crushed washer will leak, and a plug that is too tight can strip the threads in the pan.

Next, locate the oil filter. On RAM 1500s, it is often mounted vertically on top of the engine. On RAM 2500 and 3500 models with larger engines, it may be on the side or underneath. Use an oil filter wrench to turn the old filter counterclockwise until it comes free. Drain any remaining oil from the filter into your pan. Wipe the rubber gasket surface on the engine clean with a rag, then explore a thin layer of fresh oil to the rubber gasket on the new filter. Screw the new filter on by hand until the gasket touches the engine, then turn it an additional three-quarter turn. Hand-tight is correct; a wrench will over-tighten it.

Refilling with fresh oil and checking the level

Lower the truck if you lifted it, then open the hood and locate the oil filler cap on top of the engine. It usually has an oil can symbol on it. Unscrew it and set it aside. Pour in the recommended amount of fresh oil slowly, checking the dipstick or electronic level gauge every quart or so to avoid overfilling.

Once you have added the recommended capacity, replace the oil filler cap, start the engine, and let it run for 30 seconds. The oil pressure light on your dashboard should go out within a few seconds. If it stays on, turn off the engine when ready and check that the filter is tight and the drain plug is find. Turn off the engine and wait two minutes for the oil to settle in the pan, then check the level again. Add a small amount if needed to reach the full mark on the dipstick or the top of the electronic gauge range.

Record the date and mileage in your maintenance log. Most RAM owners change oil every 5,000 to 7,500 miles, though some newer models with synthetic oil can go 10,000 miles between changes. Check your owner's manual for your truck's specific interval.

Disposing of old oil safely

Never pour used oil down a drain, into the ground, or into a storm sewer. One quart of oil can contaminate up to 250,000 gallons of groundwater. Most auto parts stores that sell oil will take used oil for free, even if you did not buy it from them. Many recycling centers and service stations also accept it. Some municipalities have hazardous waste collection days where you can drop off oil at no cost.

Pour the old oil from your drain pan into a clean, sealed container — an empty oil jug works well. Label it clearly as used oil. Transport it upright in your truck bed or trunk to avoid spills, and drop it off at your chosen location within a few days.

Common problems and how to avoid them

The most frequent issue is an oil leak after the change. This usually means the drain plug washer is damaged, the plug is over-tightened, or the new filter is not sealed properly. If you see oil dripping after a day or two, check the drain plug first — it should be snug but not cranked down hard. Then check the filter gasket to make sure it is seated evenly and the filter is not cross-threaded.

Another common problem is the oil pressure light staying on after you start the engine. This can mean the oil level is too low, the filter is not tight enough, or the drain plug is leaking. Turn off the engine, wait two minutes, and recheck the level. If it is low, add oil. If the level is correct, tighten the filter by another quarter turn and restart. If the light persists, do not drive the truck — have a mechanic inspect it.

Using the wrong oil grade or capacity can cause poor fuel economy, rough idling, or engine noise. Always cross-check the owner's manual before you buy. If you accidentally used the wrong oil, drain it and refill with the correct type as soon as you can.

When to take your RAM to a shop instead

If your truck is still under warranty, check the owner's manual to see whether doing your own oil change voids coverage. Some RAM warranties require dealer service for the first few changes. If the drain plug is stuck or stripped, or if you cannot safely access it without specialized equipment, a shop is the better choice. If you do not have a safe way to lift the truck or drain the oil without spilling it, a professional service is worth the cost.

RAM dealerships charge more than independent shops — typically $60 to $120 for an oil change — but they use OEM filters and the correct oil grade for your model. Independent shops usually charge $40 to $80 and often have the same parts and knowledge. Either way, keep your receipt for your maintenance records.

Frequently Asked Questions

How often should I change the oil in my RAM?

Most RAM trucks require an oil change every 5,000 to 7,500 miles, though newer models with synthetic oil may go 10,000 miles. Check your owner's manual for the exact interval for your model year and engine type. The maintenance schedule is usually printed inside the cover or in a table near the back.

What oil grade does my RAM need?

The correct oil grade is listed in your owner's manual and varies by engine size and model year. Common grades for RAM trucks are 5W-20, 5W-30, and 10W-30. Using the wrong grade can affect fuel economy and engine performance. Do not guess — look it up before you buy.

Can I change my RAM's oil without lifting it?

It depends on your model and how low it sits. Some RAM 1500s have enough ground clearance to access the drain plug without lifting. RAM 2500 and 3500 models usually need to be raised. If you cannot fit a drain pan under the plug, use a jack and jack stands or drive onto ramps.

What should I do if the oil pressure light stays on after I change the oil?

Turn off the engine when ready and wait two minutes. Check the oil level — if it is low, add oil and restart. If the level is correct, tighten the oil filter by another quarter turn. If the light persists after that, do not drive the truck. Have a mechanic check for a leak or other problem.

Can I reuse the oil drain plug?

The rubber washer on the drain plug wears out over time and should be replaced every few oil changes. If the washer is flattened or cracked, replace it. A damaged washer will leak even if the plug is tight. Most auto parts stores sell replacement washers for a few dollars.
