Wynn's Engine Oil Flush 425 ml, Pack of 2

What it is meant to do

A pre-oil-change engine flush that helps lift out sludge, varnish and other contaminants from oil-lubricated systems.

This Wynn's engine oil flush is made for cleaning the inside of a system before an oil change. According to the listing, it helps remove sludge, varnish and other contaminants from oil-lubricated systems, making it a good fit for build-up that can interfere with lubrication and leave fresh oil doing more work than it should.

The product information says each unit in the pack can be used in engines, hydraulic systems, gearboxes and differentials, and that it is compatible with mineral, synthetic, single-grade and multigrade oils. It is also listed as suitable for regular and low SAPS applications.

• Helps dissolve internal deposits before the old oil is drained

• Can help free internal parts that have become sticky or gummed up
• Is described as helping quieten noisy hydraulic valve lifters

Points to check before buying
