Liqui Moly Engine Flush Plus: the internal engine clean before your oil change
Imagine paying for good new oil… and pouring it into an engine full of old dirt. In seconds, that fresh oil is already contaminated. To avoid it there’s Liqui Moly Engine Flush Plus — what many people in Spain search for as “limpiador interno del motor”.
The mistake almost nobody sees
Over the miles, sludge, varnish and carbon deposits build up inside the engine. It’s invisible from outside, but it’s there, stuck in the galleries the oil flows through.
If you change the oil without cleaning first, the new oil drags out some of that muck and loses its properties from minute one. You paid for clean lubricant and it works dirty.
What Engine Flush Plus is (internal engine cleaner)
It’s a deep-cleaning additive added to the old oil right before you change it. With the engine warm, you let it idle for about 10 minutes.
During that time, the product dissolves the internal dirt and holds it in suspension. Nothing needs dismantling: it all ends up floating in the old oil.
What it cleans inside
Engine Flush Plus works where a simple oil change can’t reach:
- Dissolves sludge and varnish from the oil galleries
- Helps free up stuck piston rings
- Cleans the hydraulic lifters (less engine noise)
- All that dirt leaves with the old oil when it’s drained
Why it makes so much sense in Málaga
Here two engine-dirtying uses combine: long motorway trips and everyday city traffic, with cold starts and short journeys. That mix encourages deposits to form.
So, before adding the new oil, this clean is worth it. It’s a small step that protects a very expensive machine.
