Step-by-Step Instructions
Follow these steps carefully
1
Confirm oil specification and make the vehicle safe
Your 2015–2018 GLA 250's 2.0L turbo M270 holds 6.0 quarts of 0W-40 with the filter changed. Pick up cartridge element Mercedes A2701800109, 13mm socket, and 24mm socket with a long extension for the filter cap. Park level; raise the front on jack stands or ramps — never rely on the jack alone.
🔧 Mechanic's note — Ray Delgado
The GLA 250's M270 wants 0W-40 meeting spec 229.5 — I verify that on the bottle because the wrong grade in this turbo is a slow death. Cartridge A2701800109, 24mm socket on a long extension, and patience up front.
2
Warm briefly and protect the work area
Remove the underbody panel — seven 8mm nuts — to expose the oil pan. Slide the drain pan under the Mercedes-Benz GLA 250's oil pan and spread cardboard under the work area for drips.
3
Drain the used oil and replace the filter
Unscrew the front-mounted cartridge housing cap with the 24mm socket on a long extension. Swap in the new cartridge with its fresh O-rings lightly oiled, and reseat the cap. Thread the plug back in by hand and snug it firmly.
🔧 Mechanic's note — Ray Delgado
I work the GLA's front-mounted cartridge from above with the 24mm on a long extension — the housing is plastic, so the cap goes back hand-snug. Reefing on it cracks the housing and then you're ordering parts instead of driving.
4
Install the correct oil quantity
Set a funnel in the Mercedes-Benz GLA 250's filler neck and pour in 6.0 quarts of 0W-40. Pour slowly and watch the markings as you go. Use only oil meeting Mercedes spec 229.5.
🔧 Mechanic's note — Ray Delgado
Six quarts in the GLA, poured slow while I watch the markings — the 229.5 spec is strict on these engines and the funnel neck is narrow. Slow pours keep oil off the engine bay and the level exactly where it belongs.
5
Check level and leaks
Idle the engine a full minute, watching the plug and filter area for leaks. Shut it off and wait two minutes. Pull the dipstick, wipe it, reseat it fully, and read the level — top up if below full.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Using the wrong viscosity, capacity, or filter
- • Working under a vehicle supported only by a jack
- • Reusing a crushed drain-plug washer or leaving the old filter gasket stuck
- • Over-tightening the filter or drain plug
- • Starting the engine before checking the oil level and leaks
