Introduction
The first time I changed the oil on my wife’s 2013 Hyundai Elantra, I did what most people do: I crawled under the car, yanked the drain plug, and then spent 20 minutes Googling “what torque for Elantra oil pan bolt?” while oil dripped on my sleeve. That rookie hour cost me a new crush washer, a shirt, and whatever pride I had left.
Since then I’ve performed the service on every generation of Elantra that has rolled into my two-bay home garage—from the angular 2011 model to the spaceship-looking 2024—with a combined 247,000 miles on the odometers. The job is still a 30-minute driveway project, but the details change slightly every few years. Oil capacity bumped from 4.2 to 4.5 quarts, cartridge filters replaced spin-ons, and Hyundai’s bulletin on 0W-20 full-synthetic quietly superseded the old 5W-20 recommendation.
This article distills everything I’ve learned into one human-friendly walkthrough. You’ll get the exact tools, torque values, real-world part numbers, and the “why” behind each step so you can finish the job confident the engine will purr for another 7,500 miles—without inventing creative new curse words.

Why Elantra Oil Changes Matter More Than You Think
Hyundai’s 1.8 and 2.0-liter engines are famously sensitive to oil quality. The timing chain tensioners are hydraulically actuated—run them on dirty, shear-thinned oil and you’ll hear the dreaded “start-up rattle” that precedes a $900 tensioner job. Clean oil also keeps the high-pressure fuel pump cam follower alive; I’ve replaced scored followers on cars that stretched the 7,500-mile interval to 11,000 because “the dash hadn’t lit up yet.”
On the flip side, I’ve seen 2012 Elantras crest 280,000 miles with flawless compression because the owner—an Uber driver—changed synthetic oil every 5,000 miles like church. The lesson: the Elantra rewards cheap, routine maintenance and punishes neglect with expensive noises.

Gathering the Right Stuff—Tools, Oil, and Filter
You only need six tools to look like a pro:
-
17 mm socket and ratchet (drain plug)
-
Torque wrench that reads 20–30 Nm (crucial—overtightening warps the pan)
-
Oil-filter cap wrench—Hyundai part 09263-2E000 or a $8 aftermarket 65 mm 14-flute cup
-
5-quart drain pan with built-in spout (trust me, the $12 version beats milk jugs)
-
Nitrile gloves and a fleece blanket to lie on (cold Wisconsin driveways suck)
-
Funnel that fits the cam-cover dipstick tube—prevent the “synthetic Valdez” down the block
Oil: Hyundai’s latest TIS bulletin (2023) specifies full-synthetic 0W-20 for all 2017+ Elantras, and 5W-20 or 0W-20 for 2011-2016. I use Pennzoil Platinum or Mobil-1 because both carry the dexos1 Gen-3 license that guarantees timing-chain wear protection. Capacity is 4.2 qt (2011-2016) or 4.5 qt (2017+) including filter—buy a 5-quart jug and you’ll have a splash left for top-offs.
Filter: Skip the cheap orange cans. OEM Hyundai filter 26300-35504 (spin-on) or 26350-2S000 cartridge costs $7 at the dealer and comes with the new O-rings you’ll need. If you hate dealer lines, Wix 51334 or Fram Ultra XG9688 are solid aftermarket picks.

Pre-Jack Ritual: Warm-Up, Positioning, and Safety
Drive the car 5–7 minutes—just enough to hit 140 °F oil temp. Warm oil drains faster and carries more suspended soot with it, but don’t burn yourself on a scalding pan.
Park on level ground, engage parking brake, chock rear wheels, and pop the hood to loosen the oil-fill cap. This prevents vacuum lock and lets the last half-quart glug out smoothly.
Ramps vs. jack stands: My 2022 Elantra sits 5.1 inches off the ground—too low for my old Rhino ramps. I use a low-profile floor jack on the front subframe center beam, then 3-ton stands under the pinch-weld reinforced tabs. Place a folded towel on the stand saddle so you don’t chip the paint Hyundai lovingly applied to rust-prone Wisconsin steel.

The Step-by-Step Drain & Refill
Step 1 – Under-tray removal
Seven 10 mm bolts and three plastic push-pins. Keep a magnetic parts tray; those bolts love grass.

Step 2 – Position drain pan
Center it under the 17 mm drain plug, but offset 2 inches rearward—when the stream arcs it’ll travel farther than you expect.

Step 3 – Break the plug
Use a 6-point socket; 12-point rounds the shoulders. Once loose, spin it out with your fingers and pull away quickly so the oil misses your wrist.

Step 4 – Remove old filter
Spin-ons: use a cap wrench, then drain for 5 minutes so the filter media doesn’t dump on you during removal.
Cartridge (2019+): remove the 65 mm plastic housing with the special socket. Pry the old paper element out with a pick; note the tiny molded date—Hyundai recommends changing at every oil change, not every other.

Step 5 – Prep new filter
Spin-on: smear fresh oil on the rubber gasket and hand-tighten three-quarters turn after contact.
Cartridge: replace both O-rings on the plastic cap—lubricate them so they don’t pinch and tear.

Step 6 – Reinstall drain plug
Clean the magnetic tip with a rag; if you see silvery fuzz, that’s normal wear. Thread by hand, then torque to 25 Nm (18 lb-ft). Any tighter and you’ll emboss the soft aluminum pan.

Step 7 – Add new oil
Insert funnel, pour in 4.0 qt, start engine for 30 seconds, shut off, wait 2 minutes, then check dipstick. Add remaining half-quart incrementally until the top hole is centered. Overfilling 0.2 qt is fine; 0.5 qt can froth and collapse the A/C compressor belt.

Step 8 – Reset maintenance minder
2011-2016: Hold trip button with key on (no start) until “Service” blinks.
2017+: Use steering-wheel arrows to navigate User Settings → Service Interval → Reset.

Insider Tricks That Save Skin, Time, and Money
-
Zip-tie a sandwich bag around the filter while removing it—catches the half-cup of oil that otherwise baptizes the axle.
-
Mark the filter and drain plug with white paint pen after torquing; a quick visual confirms nobody at Quick-Lube double-gunned it later.
-
Buy oil in 5-qt jugs when AutoZone runs 25% off plus $10 rebate. I stack rebates and average $28 for synthetic—cheaper than conventional in 2014 dollars.
-
Keep a spare drain-plug washer in the glovebox. The concentric ridges crush only once; re-using it risks a slow weep that smells like French fries at every stoplight.
-
If you live where winter hits -10 °F, switch to 0W-20 even on older Elantras. Cold-start flow improves 12% and the engine cranks faster, saving the tiny battery Hyundai regrettably undersized.

Common Mistakes That Create 3 A.M. Forum Posts
Cross-threading the cartridge cap
The plastic threads start easily, but if you force it at an angle you’ll chew the housing—$85 dealer-only part. Spin backwards until you feel the threads drop, then clockwise.

Double-gasketing the filter
Old O-ring stuck to the block plus new filter equals 60-psi oil volcano. Run your finger around the mounting surface before spinning on the new filter.

How Often Should You Really Change It?
Hyundai’s 7,500-mile interval assumes ideal highways and top-tier gasoline. Real world: short-hop grocery runs, winter idling, and ethanol-laced fuel dilute the oil. I send samples to Blackstone Labs; they consistently show 5,000-mile viscosity breakdown on turbo Elantras and 6,000 on non-turbo. My compromise: 5,000 miles in severe service (Uber, Canadian winter, mountain roads) and 6,500 in gentle highway duty. The extra $25 every few months is cheaper than one VVT solenoid.

Eco-Friendly Disposal and Bonus Cash
Pour used oil into the now-empty 5-qt jug, screw cap tight, and drive it to any AutoZone, O’Reilly, or dealership—they recycle for free. Pro-tip: keep the receipt; in Wisconsin, Advanced Auto mails a $5 coupon for every 5 gallons you bring back. Over a year that’s a free air filter.
FAQs
Q1: Can I use 5W-30 instead of 0W-20 for summer?
A: Hyundai allows 5W-30 as an emergency top-off, but stick with 0W-20 for best fuel economy and timing-chain protection. Thicker oil increases pump effort and can drop MPG by 1–2.

Q2: Do I really need synthetic if the manual says “conventional allowed”?
A: The 2011-2016 books list conventional, but Hyundai quietly revised the spec after tensioner failures. Synthetic keeps viscosity index stable; it’s $12 extra per change and doubles your engine life odds.

Q3: Why is my oil still dark after 500 miles?
A: Modern detergents turn oil espresso-brown quickly—that’s it doing its job. Color is not a wear indicator; send a sample if you want science.

Q4: Torque wrench necessary or can I go “snug”?
A: Aluminum pans gall easily. 25 Nm is only wrist-tight with an 8-inch ratchet—use a wrench. I’ve helicoiled too many stripped pans for people who “felt tight enough.”

Q5: Is the vacuum extractor method okay?
A: Top-side suction misses the 200 ml of sludge sitting below the pickup—fine for mid-cycle top-offs, not for full changes. Roll up your sleeves and pull the plug.

Q6: Dealer charges $39.95—why bother DIY?
A: They bulk-fill 5W-20 conventional, re-use your washer, and reset the interval to 3,000 miles to upsell early returns. DIY guarantees correct oil, new filter, and the satisfaction of not sitting in a waiting room that smells like burnt coffee.

Conclusion
Changing the oil in your Hyundai Elantra isn’t a badge of mechanic honor—it’s 30 minutes of quiet, methodical work that pays you back every single start-up. You get the right oil, the right filter, the right torque, and the peace of mind that no corners were cut while someone’s manager hovered with a clipboard. Grab the tools once, and the second time you’ll finish before your podcast episode ends. Your engine will reward you with years of quiet timing chains, smoother cold starts, and maybe—if you keep the receipts—a few extra Benjamins when you sell. See you at the 5,000-mile mark.
