What Size Is My Oil Drain Plug? Quick Guide for Ford, Toyota, Honda & More

It’s Saturday morning, and Mark’s checklist had one simple item: "Change oil in the Honda."He slid under his car, ready for a quick oil change, wrench in hand, pan in place, only to discover the socket doesn’t fit the drain plug. He tried another one, still no luck. 

An hour later, Mark was staring at a slightly rounded, still-stuck drain plug, his hands covered in dirty oil from failed attempts with locking pliers. His "simple" 30-minute job was now a greasy, knuckle-busting nightmare. Oil changes aren’t supposed to start with frustration, right?

If you’ve ever been there, you’re not alone. Drain plug sizes vary from brand to brand,  what fits your Ford won’t fit your Honda, and your Toyota might need something entirely different. That’s why one of the most common questions DIY mechanics ask is: “What Size Is My Oil Drain Plug?”

The truth is, there’s no single answer. Every manufacturer designs their engines differently, and even models from the same brand can have different plug sizes depending on the year or engine type. Using the wrong socket doesn’t just waste time,  it can strip bolts, cause leaks, or even damage your oil pan.

But here’s the good news: you don’t have to memorize every size chart. With the right tool set, you’ll always have the correct socket within reach.  In this quick guide, we’ll show you the most common oil drain plug sizes for Ford, Toyota, Honda, and other popular car brands, and show you why investing in a universal drain plug socket set like the BILITOOLS 23-Piece Drain Plug Socket Set is the smartest move for any DIYer or professional mechanic who values speed, precision, and peace of mind.

• Using the wrong size can cause leaks or stripped plugs.

Why Oil Drain Plug Sizes Matter

Oil drain plugs aren’t one-size-fits-all. The wrong socket size can lead to:

• Rounded or stripped plugs (making them impossible to remove)
  
  
• Oil leaks due to improper torque
  
  
• Extra repair costs from damaged pans

Each manufacturer uses different thread sizes, head types, and materials. Some use metric sizes, others SAE (imperial). The result? Frustration, unless you have a socket for every scenario.

That’s where the BILITOOLS 23-Piece Drain Plug Socket Set comes in. It includes the most-used metric and SAE sizes, so you’re covered whether you’re working on a Ford F-150 or a Toyota Camry.

Common Oil Drain Plug Sizes by Brand

Here’s a quick reference list to save you time during your next oil change:

Ford

• Common Sizes: 13mm, 15mm, 19mm
  
  
• Some trucks use 5/8” SAE plugs.
  
  
• Pro Tip: Apply moderate torque and replace the washer every oil change.

Toyota

• Common Sizes: 14mm or 17mm
  
  
• Models like Corolla and Camry typically use 14mm; Tacoma or Highlander use 17mm.

How to Identify Your Oil Drain Plug Size (Without Guesswork)

If you’re not sure what size your drain plug is, here’s how to figure it out:

1. Check Your Owner’s Manual – Look under the maintenance or lubrication section.
   
   
2. Use a Caliper or Ruler – Measure across the bolt head (flat to flat).
   
   
3. Do a Socket Test – Start with smaller sockets (12mm) and size up until snug.
   
   
4. Look for Markings – Many plugs are stamped with size indicators (e.g., “M14”).
   
   
5. Avoid Adjustable Wrenches – They’re prone to slipping and can damage the bolt head.

✅ Pro Tip: Oil plug sizes can even vary within the same brand or model depending on year and trim, so a full kit like BILITOOLS 23-Piece Drain Plug Socket Set ensures you’re always covered.

Why Buy One Socket When You Can Own Every Size?

Here’s the truth: car manufacturers change plug designs, materials, and sizes all the time. What fits a 2016 Toyota Corolla may not fit a 2022 model.

Rather than hunting for single sockets, it makes sense to invest once in a complete set.

When to Replace Your Oil Drain Plug

Even the best sockets can’t save a plug that’s past its prime.

• Leaking oil after tightening

• Magnetic tip full of metal shavings

A BILITOOLS set ensures you always have the right replacement socket to safely remove old plugs without damaging the threads.

Frequently Asked Questions (FAQs)

1. What size socket do I need for my car’s oil drain plug?

Most cars use oil drain plugs between 13mm and 17mm, depending on the brand. For example, Toyota and Honda typically use 14mm or 17mm, while Ford often uses 13mm or 15mm. Using a universal drain plug socket set like the BILITOOLS 23-Piece Kit ensures you always have the right size on hand.

2. Can I use an adjustable wrench for an oil drain plug?

While you can, it’s not recommended. Adjustable wrenches often slip and can strip the plug’s edges, leading to leaks or expensive repairs. A 6-point socket from a drain plug socket set provides a perfect fit and prevents damage.

3. How can I tell if my oil drain plug is stripped or damaged?

If your wrench slips, or if you notice metal shavings, oil leaks, or rounded edges, your plug may be stripped. Replace it immediately and always use the correct socket size to avoid future damage.

4. What’s the most common oil drain plug size for a Toyota or Honda?

• Toyota: Usually 14mm (Corolla, Camry, Tacoma)
  
  
• Honda: Usually 17mm (Civic, Accord, CR-V)
  A multi-size kit like the BILITOOLS 23-Piece Set ensures coverage for both brands, and many others.

5. Why should I buy a full drain plug socket set instead of individual sockets?

Different vehicles use different plug sizes, even within the same brand. A complete socket set means you’re prepared for any car, perfect for DIYers, family garages, or small repair shops. It saves time, prevents guessing, and eliminates trips to the store mid-job.

6. Is the BILITOOLS 23-Piece Drain Plug Socket Set compatible with all cars?
