Quick Answer
The 2018 Toyota Camry 2.5L takes 4.4 quarts of oil. Use SAE 0W-20 full synthetic. Always change the filter with the oil.
Check the dipstick after refilling. Never overfill or underfill the engine.
Why Getting the Oil Capacity Wrong Costs You Money
Think of engine oil as your Camry's lifeblood. Too little and metal parts grind together. Too much and seals blow out.
Either way, you're looking at a repair bill that dwarfs the cost of a simple oil change.
Our research shows that overfilling the 2.5L engine by just half a quart can cause the crankshaft to whip the oil into foam. Foam doesn't lubricate. It leads to hot spots, accelerated wear, and in some cases, catastrophic failure.
Underfilling is just as bad. Running low on oil starves the variable valve timing system. The A25A-FKS engine relies on oil pressure to adjust cam timing.
Drop below the minimum level and you'll notice rough idling, reduced power, and eventually, engine knock.
The right amount matters. The right viscosity matters. Get both correct and this engine will easily run past 200,000 miles.
What's Inside the 2018 Camry 2.5L Engine
The A25A-FKS Engine and Its Oil Needs
The 2018 Camry 2.5L uses Toyota's A25A-FKS engine. This is a direct-injection, four-cylinder engine with a complex oil system. It uses a chain-driven oil pump that varies its output based on engine load.
This engine has tight tolerances. The bearing clearances are small. That's why it needs thin 0W-20 oil.
Thicker oil won't flow fast enough during cold starts. It will leave metal parts unprotected until the engine warms up.

Why 0W-20 Is Non-Negotiable
The "0W" means the oil flows like a weight-zero grade at cold temperatures. The "20" means it thickens to a 20-grade at operating temperature. This combination gives you cold-start protection and fuel economy.
Toyota's engineers designed this engine around 0W-20. Using 5W-30 or 10W-30 increases drag on the rotating assembly. Our research shows this can reduce fuel economy by 2 to 3 percent.
It also increases wear during the first few minutes of operation.
The API SN Plus certification is important too. This standard prevents low-speed pre-ignition, a problem that can destroy direct-injection engines. Look for the API donut symbol on the bottle.

The Real Capacity: With Filter vs. Without Filter
Here's where people get confused. The 2018 Camry 2.5L holds different amounts depending on whether you change the oil filter.
| Condition | Oil Capacity |
|---|---|
| With filter change | 4.4 quarts (4.2 liters) |
| Without filter change | 4.2 quarts (4.0 liters) |
Always change the filter. It costs less than ten dollars. A clogged filter bypasses unfiltered oil into your engine.
That defeats the purpose of an oil change.
Manufacturer specifications indicate the filter holds about 0.2 quarts of oil. When you remove the old filter, that oil drains out. Refilling with 4.4 quarts brings the system to the full mark.
If you only drain the oil and leave the old filter in place, add 4.2 quarts. Then check the dipstick. Top off as needed.
Risks You Face When You Get It Wrong
Overfilling: The Silent Leak Creator
Add too much oil and the crankshaft dips into the oil pan. It churns the oil into foam. Foam has air bubbles.
Air bubbles don't lubricate. The oil pump sends this foamy mixture through the engine, causing accelerated wear.
Overfilling also increases pressure inside the crankcase. This pushes oil past seals and gaskets. You'll see leaks around the valve cover, the oil pan, and the front crankshaft seal.
A rear main seal replacement costs hundreds of dollars in labor alone.
Underfilling: The Engine Wear Accelerator
Too little oil means the oil pump can suck air during hard cornering or acceleration. The variable valve timing system loses pressure. The cam phasers can't adjust timing properly.
You'll notice a rough idle first. Then a check engine light. If you ignore it, the engine starts knocking.
By then, the damage is done.
Wrong Viscosity: The Fuel Economy Killer
Thicker oil creates more drag. The engine has to work harder. Fuel economy drops.
In cold weather, thick oil struggles to reach the top of the engine. The valvetrain runs dry for precious seconds during startup.
The 0W-20 specification isn't a suggestion. It's a requirement. Toyota's engineers designed the oil passages and pump around this viscosity.
Changing it invites problems. The hybrid version's specific needs are covered in our guide to the 2025 Camry Hybrid oil type.
Step-by-Step: How to Do the Oil Change Right
What You'll Need (Tools and Parts)
| Item | Specification |
|---|---|
| Engine oil | 4.4 quarts of SAE 0W-20 full synthetic |
| Oil filter | Toyota part #04152-YZZA1 or equivalent |
| Crush washer | 14mm, replace every time |
| Socket wrench | 14mm socket for drain plug |
| Oil filter wrench | Cap-style or strap wrench |
| Jack and stands | For lifting the front of the car |
Warm-Up and Drain Procedure
Warm the engine for five minutes. Hot oil drains faster. Park on level ground.
Lift the front of the car and secure it with jack stands. Never work under a car supported only by a jack.
Remove the oil fill cap. Place the drain pan under the plug. Loosen the drain plug with the 14mm socket.
Remove it by hand. Let the oil drain completely. This takes about five minutes.
Filter Replacement the Right Way
Move the drain pan under the filter. The A25A-FKS filter is on the front of the engine, facing downward. Loosen it with the filter wrench.
Spin it off by hand.
Before installing the new filter, lubricate the rubber gasket with fresh oil. This prevents the gasket from sticking. Screw the filter on by hand until the gasket contacts the mounting surface.
Tighten it another three-quarters of a turn. Do not overtighten.
Refilling and Checking the Dipstick
Install the drain plug with a new crush washer. Torque it to 29 ft-lbs. Pour in 4.4 quarts of 0W-20.
Replace the oil fill cap.
Start the engine. Let it run for 30 seconds. Check for leaks around the drain plug and filter.
Shut the engine off. Wait five minutes for the oil to settle.
Pull the dipstick. Wipe it clean. Insert it fully.
Pull it again. The oil level should be between the two marks. If it's low, add a quarter quart at a time.

Common Mistakes DIYers Make (and How to Avoid Them)
Stripping the Drain Plug
The drain plug is aluminum. It's soft. Using an impact gun or overtightening with a breaker bar strips the threads.
A stripped oil pan requires a replacement or a thread repair insert. Both cost more than a professional oil change.
Use a torque wrench. Set it to 29 ft-lbs. That's snug, not tight.
Forgetting the Crush Washer
The crush washer creates a seal between the drain plug and the oil pan. Without it, oil seeps out slowly. You might not notice until your driveway has a stain and your engine is low on oil.
Replace the crush washer every time. They're cheap. Buy a pack of ten and keep them with your oil change supplies.

Skipping the Dipstick Check
Some people pour in 4.4 quarts and assume the level is correct. It might not be. Residual oil in the engine, an angled car, or a different filter brand can change the final level.
Always check the dipstick. It takes 30 seconds. It's the only way to confirm the correct level.
Older Camry models follow the same basic procedure, as shown in our guide to the 1997 Camry oil type.
How Often Should You Change It? (Interval Guidance)
Toyota recommends an oil change every 10,000 miles for normal driving conditions. That's for standard use. But your driving habits matter.
| Driving Condition | Recommended Interval |
|---|---|
| Normal highway driving | 10,000 miles |
| Stop-and-go city traffic | 5,000 to 7,500 miles |
| Frequent short trips under 5 miles | 5,000 miles |
| Towing or heavy loads | 5,000 miles |
| Extreme cold or hot climates | 5,000 to 7,500 miles |
The A25A-FKS engine has a direct-injection system. This system can build up carbon deposits on the intake valves. Clean oil helps reduce this buildup.
Changing oil at shorter intervals in severe conditions is cheap insurance.
Check the oil level monthly. Between changes, the level should stay consistent. If it drops, you may have a leak or the engine may be burning oil.
Toyota's four-cylinder oil recommendations for the 2025 Corolla follow similar logic.
When to Call a Pro Instead of Doing It Yourself
DIY oil changes save money. But they're not for everyone. Here's when you should let a shop handle it.
You don't have a level place to work. You don't own jack stands. You can't lift 30 pounds of oil safely.
Any of these reasons are valid. A professional oil change costs between $60 and $90. That includes oil, filter, and disposal.
If your Camry is still under warranty, a dealership might insist on documented oil changes. Keep receipts if you DIY. Or let the dealer handle it for peace of mind.
If you have a leak or a mechanical issue, don't change the oil yourself. Fix the problem first. Then do the oil change.
A shop can diagnose and repair in one visit. The National Institute for Automotive Service Excellence (ASE) certifies technicians who meet rigorous standards, so you can trust a qualified shop.
The Cost Breakdown: DIY vs. Shop
Let's compare the numbers. Prices vary by location, but here's a realistic picture as of 2026.
| Item | DIY Cost | Shop Cost |
|---|---|---|
| Oil (4.4 quarts 0W-20) | $25 to $35 | Included |
| Oil filter | $6 to $10 | Included |
| Crush washer | $0.50 | Included |
| Labor | Free | $30 to $50 |
| Disposal fee | Free (drop at auto parts store) | Included |
| Total | $32 to $46 | $60 to $90 |
DIY saves $20 to $50 per change. Over five years and 50,000 miles, that's $100 to $250 in savings. Enough for a new set of floor mats or a tank of gas.
The trade-off is your time and effort. A DIY change takes 30 to 45 minutes. A shop takes an hour or two depending on the wait.
The larger engine's oil specs for the Tundra V6 follow a similar cost structure.
