Oil Spray Under My Car: A Quick Guide

As a car owner, you must be concerned for the health of your vehicle.

From its engine to its exterior, oil spraying your car’s undercarriage can ensure its longevity and optimal performance.

But have you ever stopped to consider that undercarriage is often neglected when oil spraying is needed – yet just as essential!

In this guide we’ll examine why oil spraying the undercarriage of your vehicle is important, and answer the age-old question “should I oil spray under my car?


What is Oil Spray and How Does it Work?

Oil spray, also referred to as rustproofing, is a method used to shield your car’s undercarriage from rust and corrosion.

An oil-based inhibitor is applied onto the surface of the undercarriage creating a protective coating that shields it from salts, water damage, and other damaging substances from coming into contact with metal surfaces – thus avoiding rust formation.


The Benefits of Oil Spraying Your Car

Prevents Rust and Corrosion

Oil spraying your car has the primary benefit of rust prevention.

Rust is a common issue, especially in areas that get salted during wintertime.

Salt can cause rust and corrosion to your vehicle’s metal surface, potentially resulting in serious damage if left unchecked.

Oil spray creates an effective barrier between it and corrosive elements, effectively stopping rust formation.


Extends the Life of Your Car

Extending the life of your vehicle helps maximize its efficiency and durability so that it lasts longer and provides you with greater value for the money spent.

Oil spraying your car’s undercarriage helps extend its life by protecting it from rust and corrosion damage.

Rust can weaken its structural integrity, leading to parts breaking down prematurely.

By oil spraying regularly, you can prevent this from occurring and extend its usefulness.


Saves You Money

Oil spraying your car can be a cost-effective decision in the long run.

Repairing or replacing parts damaged due to rust is often expensive, so oil spraying your vehicle helps you prevent rust formation and avoid costly repairs down the line.


When Should You Oil Spray Your Car?

The ideal time to oil spray your car is before winter begins.

Salt used during de-icing roads can cause rust and corrosion on the undercarriage of your vehicle, so by oil spraying before winter you protect it from salt damage and extend its life expectancy.


How Often Should You Oil Spray Your Car?

How often you oil spray your car depends on several factors, such as climate, driving conditions, and the age of your vehicle.

As a general guideline, oil spraying your vehicle every two years is recommended; however, if salt is heavily used in your area then more frequent oil applications may be necessary.



Oil spraying your car’s undercarriage is an effective way to prevent rust and corrosion, extend its lifespan, and save you money in the long run.

It’s recommended that you have a professional oil spray your vehicle every two years–especially before winter months when salt is used on roads.

By oil spraying your automobile, you can guarantee its optimal performance as well as protect it from costly repairs in future.
