Modern vehicles are marvels of engineering, but beneath the hood lies a constant battle against an age-old enemy—corrosion. Every nut, bolt, gear, and chassis component is at risk the moment metal meets moisture. In the high-stakes world of automotive manufacturing, where precision and reliability rule, rust preventive oils play a crucial behind-the-scenes role.
One brand leading this protection mission is Growel, whose advanced Grodal rust preventive oils are trusted for their long-lasting, cost-effective corrosion control. In this blog, we’ll explore how these oils work, where they’re used, how they boost machine and part life, and even name five real automotive companies that rely on rust preventives.
Why Rust Prevention Matters in the Auto Industry
Cars today are lighter, faster, and made with more precision than ever—but they’re still mostly made of metal. As vehicles pass through stamping, welding, machining, and assembly, their parts are exposed to humidity, air, and handling. Even a small speck of rust can compromise performance, structural integrity, or safety.
According to CorrosionIndia.org, corrosion-related issues cost the global automotive sector billions annually. That’s why manufacturers protect parts with rust preventive oils from day one.
5 Real Car Brands Using Rust Preventives in Manufacturing
1. Toyota
Known for reliability, Toyota integrates rust prevention into every production stage, especially for chassis parts, fasteners, and drivetrain components.
2. Volkswagen (VW)
Volkswagen uses rust-preventive oils during the manufacturing and export process for axles, brake systems, and engine components.
3. Hyundai
The company relies on rust protection for precision parts used in powertrains and transmissions, especially during interim storage between production stages.
4. Mahindra & Mahindra
As a leading SUV and tractor manufacturer in India, Mahindra applies rust preventive oils for long-term storage of spare parts and subassemblies.
5. Tata Motors
Tata’s commercial vehicle and passenger car production involves significant use of rust preventive oils to protect parts during cross-factory shipping.
Note: These manufacturers may use various approved solutions, but in similar environments, Growel’s Grodal rust preventives are recognized for their versatile industrial-grade performance.
How Grodal Rust Preventives Are Used in Car Component Manufacturing
Grodal oils offer a wide range of options tailored for automotive manufacturing—from freshly machined parts to components awaiting export. Here’s how they’re typically used:
1. Post-Machining Protection
After components like camshafts, gears, or cylinder heads are machined, Grodal RPSB 106-H or RPSB 101 C (M) is applied. These oils displace any residual moisture and coat the surface with a micro-thin rust-inhibiting layer.
2. Storage of Spare Parts
Products like Grodal RPSB 106-P offer protection for up to 9 months in indoor environments, making them ideal for warehouse storage before final assembly or dispatch.
3. Export Preparation
Before shipping automotive assemblies overseas, manufacturers often use solvent-based aerosol sprays from the Grodal range. These create an even coat that protects metal during transit without requiring heavy degreasing later.
4. Tool and Die Maintenance
Molds and dies used for stamping or injection molding are cleaned and coated with Grodal RPSB 8065 to prevent oxidation during periods of inactivity.
5. Assembly Line Application
Spraying or dipping small components during sub-assembly using Grodal water-based options provides eco-friendly and compliant protection.
How It Increases Machine and Component Life
Rust preventives aren’t just for storage—they actively extend the service life of automotive components.
Key Benefits:
- Stops corrosion before it starts: Oils seal surfaces against oxygen and moisture, halting rust development at the molecular level.
- Preserves surface finish: Rust can roughen machined surfaces, causing premature wear and friction.
- Improves part accuracy: Clean, corrosion-free surfaces retain tight tolerances necessary for modern automotive performance.
- Reduces replacement costs: Parts that remain rust-free in storage or transit don’t need rework or discards.
- Boosts equipment health: By protecting dies, molds, and jigs, Grodal oils minimize maintenance downtime in manufacturing facilities.
What Makes Grodal Oils Unique?
Unlike standard anti-rust sprays, Grodal rust preventives are engineered for industrial use, with consistent performance across environments.
Ingredients & Advantages:
- Excellent dewatering properties – especially in RPSB 106-H
- Low film thickness – minimizes oil use while maximizing coverage
- Chlorine-free formulations – such as RPSB 8065, ensuring safe disposal and eco-compliance
