XADO Pre-Oil Change Engine Cleaner 250ml – Oil System Flush & Ring Decarbonizer with Revitalizant®

Get More from Every Oil Change

Fresh oil poured into a dirty engine is wasted oil. Residual sludge, carbon deposits, and varnish immediately contaminate the new oil — cutting its service life and reducing its protective capacity before you’ve driven a single mile. XADO Pre-Oil Change Engine Cleaner (250 ml) solves this by thoroughly purging the oil system before the drain, while Revitalizant® uses the flushing process itself to build a protective anti-wear coating on engine friction surfaces.

Three Problems. One Solution.

Problem 1: Dirty Oil System

Sludge and varnish left in the engine after an oil drain contaminate fresh oil immediately, reducing its detergent properties and shortening its effective service life. XADO cleans the oil system to technical purity before the new oil goes in.

Problem 2: Stuck Piston Rings

City driving, short trips, stop-and-go traffic, and engine overheating cause carbon to accumulate in piston ring grooves. Stuck rings lead to rising oil consumption, blue smoke, and power loss. XADO dissolves this carbon and restores full ring mobility.

Problem 3: Wear Particles Left Behind

When old oil drains, it carries away fine metal particles abraded from engine surfaces — but not all of them. Revitalizant® captures these particles and incorporates them into a ceramic-metal (cermet) protective coating on friction surfaces, turning wear debris into engine armor.

Full Feature List

• Cleans the entire oil system to technical purity
• Removes carbon and resin deposits from piston ring grooves
• Frees stuck compression and oil-scraper rings, restoring mobility
• Cleans the crankcase ventilation (PCV) system
• Eliminates hydraulic lash adjuster sticking caused by varnish buildup
• Forms an anti-wear cermet coating on friction parts during the flush
• Creates a protection reserve for the next oil service interval

Compatibility

• Gasoline, diesel, and LPG engines
• Specifically tested for turbocharged and supercharged engines
• Compatible with all motor oil types: synthetic, semi-synthetic, and mineral

How to Use

1. Warm up the engine to operating temperature, then switch it off.
2. Pour the entire 250 ml can into the engine oil filler neck.
3. Deep clean / ring decarbonization: drive 90–120 miles in normal mode before draining.
4. Routine pre-drain flush: idle for 10–15 minutes or drive ~12.5 miles, then drain.
5. Replace with fresh motor oil as normal.
