2010 Honda Civic LX
Alright — your 2010 Honda Civic is up on the lift. What can I help with?
What engine oil type and capacity should I use?
Your 1.8L holds 3.9 qt (3.7 L) with a filter change. Use SAE 5W-20 meeting API SN or newer — full synthetic is a solid choice here.

What you get

Everything you need to actually fix it

No jargon, no overwhelm. Just the answer, the steps, and the confidence to turn the wrench.

Talk it through

Describe a noise, a light, or a smell. We ask the right follow-ups and narrow it down to the likely cause.

Plug in and scan

Pair a Bluetooth OBD2 adapter to read codes, pull your VIN, and watch live data. Every code comes with a plain explanation, not just a number.

Real repair steps

Torque specs, fluid types, and factory procedures pulled from real OEM data for your exact car — the same numbers the pros work from.

Know if it's safe to drive

Before you turn the key, get a clear read on whether the issue can wait or needs attention right now.

Your garage

Keep every vehicle you own in one place, with its full history, so we always know exactly what you're working on.

Clear the light

Once the repair holds, clear the code straight from your phone and confirm the fix is really gone — no trip back to the shop.

How it works

From "what's that noise?" to fixed

Three steps. No account required to start.
