Engine Flush Plus: The Deep Clean Your Subaru Deserves Fresh oil is great, but putting it into an engine full of old sludge and deposits means it’s contaminated from the very first start. That’s why we recommend Liqui Moly Engine Flush Plus. It’s a highly effective cleaning fluid that dissolves oil-soluble and oil-insoluble residues, bringing them into suspension so they can be completely drained away during your next oil change. By clearing the engine interior of troublesome deposits, you’re allowing your fresh oil to deliver its full performance. It’s a simple, gentle, and rapid way to minimize engine wear and extend the service life of your beloved boxer. Plus, it’s been fully tested for use in turbocharged engines, so you can use it with total peace of mind in your WRX or STI.
