Step-by-Step Instructions
Follow these steps carefully
1
Confirm: 2023+ Z06 Dry Sump
This guide covers the 2023–2024 Corvette Z06 (C8, 5.5L LT6 V8). The LT6 is a TRUE DRY SUMP: oil lives in an external 8-quart tank, not the pan. You'll need Dexos R 5W-50 (NOT Dexos1), 8 quarts, a drain pan, and a funnel.
🔧 Mechanic's note — Tom Becker
I've learned: if you've only ever done wet-sump changes, reset your brain: the oil lives in that external tank, not the pan. Filling through the engine like a normal car is the classic first-timer mistake.
2
Drain BOTH Plugs (tank + pan!)
Locate BOTH drain plugs: one on the dry-sump TANK (holds the 8 quarts) and one on the oil PAN (residual). Remove the TANK plug first and let the 8 quarts drain, then remove the PAN plug for the residual.
🔧 Mechanic's note — Ray Delgado
I drain the tank first, then the pan — in that order. Guys who only pull the pan plug leave 8 quarts of old oil in the system and wonder why the fresh oil looks dirty.
3
Replace Oil Filter
Remove the oil filter (cartridge-style — verify the part for the LT6) and install the new filter element. Make sure the old element and seals came out. The 8,600-rpm LT6 needs clean oil, so use the correct LT6 filter.
4
Reinstall Both Plugs
Reinstall BOTH drain plugs with new washers. Torque specs weren't verified — tighten snugly and don't over-tighten. The tank and pan are aluminum, so don't strip the threads.
5
Add 8 Quarts to Tank (Dexos R 5W-50!)
Add 8 quarts of Dexos R 5W-50 to the dry-sump TANK — not the engine; the tank is the fill point. Use ONLY Dexos R 5W-50 — not Dexos1, not 0W-40. Don't overfill — the dry sump is sensitive to level.
6
Check Tank Level and Leaks
Check the oil level via the dry-sump tank (not a conventional dipstick) — it must be at operating temperature. Start the engine and check for leaks at both plugs and the filter.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Not allowing the engine to idle for 20 seconds before draining to return oil to the dry sump tank.
- • Overfilling or underfilling the engine oil, leading to potential engine damage.
- • Failing to properly torque the drain plug and oil filter, resulting in leaks.
