Tune-up & Injector Ultrasonic Cleaning.

Why use Ultrasonic EFI Injector cleaning?

Ultrasonic Petrol Injector cleaning uses high-frequency, high-intensity sound waves in a liquid to enhance the removal of foreign contaminants from surfaces submerged in an ultrasonically activated liquid. This is the only process that removes all contaminates from the fine internal injector passages.

Enjoy that new car feeling, save on fuel costs and get a longer trouble free life from your vehicle. You always get more and you pay less at Highway Auto Mechanical Rockhampton (07) 4926 1303.

Clean Injectors use less fuel and deliver more power.

Let's dismiss the myth that a Tune-up is the wave of the magic wand because each vehicle is an individual case and at Highways your car will be carefully inspected and diagnosed to discover just what needs to be attended to and returned to manufacturer's specifications.

When the diagnostic test results are in we do a costing and contact you for approval. We are happy to SMS or email pictures of any parts we reccomend for replacement. The price we quote is the price you pay.

Why do EFI Injectors need to be cleaned and serviced?

This accumulation eventually reduces the flow of fuel through the injector and disrupts its spray pattern, causing the engine to run lean. This can manifest itself in a number of ways, although the most common is driveability problems such as flat spots and hesitations.

The cost of the above varies with makes and models therefore we are happy to work out a custom servicing plan that is best for you and your car and at the best price.

A Tune-up improves combustion giving more power for less fuel.

Combustion Begins At The Spark Plug. The service life of spark plugs in modern engines is a lot longer than in the past. The service schedule for many vehicles these days won't include a fresh set of plugs until 100,000km or more.

Changes to fuels and improved plug materials have had a significant influence on plug life. However you can't expect the best power response on 100,000K old spark plugs. Have your spark plugs replaced every 100,000km. or sooner and enjoy renewed power and performance and use less petrol.

Every vehicle needs a quality tune-up. No matter if you drive the latest start-stop technology or a classic collectable, regularly scheduled engine maintenance is key to helping extend the life of your vehicle, maintain fuel economy and prevent major issues from occurring down the road.

Ultrasonic Petrol Injector Cleaning.

Fuel system, and more particularly, liquid injector cleaners encompass a great number of products and systems that range from simple DIY, pour into the fuel tank additives, to complex, purpose built cleaning machines. The core of fuel additives is a solvent and we are led to believe that a solvent will remove years of built up grime inside a tiny space – it won’t!

Injectors will need to be cleaned because over time they become clogged with fuel residue, which resembles varnish. This accumulation eventually reduces the flow of fuel through the injector, disrupting its spray pattern and causing driveability problems such as flat spots and hesitations. The engine management computer reads the output from its sensors and (the short story) issues inappropriate commands that you will recognise as poor running and excess fuel consumption.

Ultrasonic cleaning uses cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics. This action also penetrates blind holes, cracks, and recesses.

Most fuels contain detergents that are intended to help keep the fuel system and injectors clean, but there comes a time when it’s necessary to remove the injectors for cleaning in an ultrasound machine. It’s the sonic waves that break up the varnish and residues. Contact Us, Find Us, Get a Quote, Make a Booking
