Analysis of the Properties of Ultimate Metal Guard Engine: Advanced Anti-Corrosion Protection

Quick Summary: Why Does Rust Destroy the Engine from the Inside?

Most drivers associate corrosion solely with the bodywork, forgetting that the greatest, invisible enemy of a combustion engine is moisture and acidic chemicals. When the engine cools down, water condenses inside the block, which, combined with exhaust fumes, forms aggressive acids. The Ultimate Metal Guard Engine additive creates a non-drying, chemically bonding coating on the metal, which completely isolates the surfaces from these threats. Certified salt spray chamber tests have proven that the product can delay corrosion processes by more than 70 times. The result? No destructive iron oxide particles in the oil, perfectly smooth cylinder walls and protection for delicate bearing surfaces. Below we present the detailed results of laboratory tests.

Test description and detailed product analysis

An internal combustion engine spends most of its ‘life’ at rest. It is precisely when we switch off the ignition and the hot oil flows by gravity into the sump that a silent process of degradation begins. The phenomenon of water vapour condensation and the presence of sulphur and nitrogen oxides from the exhaust gases mean that exposed steel components are vulnerable to microcorrosion.

To prove the effectiveness of our product’s protection, we commissioned rigorous testing at the accredited Corr-Lab Corrosion Testing Laboratory.

Neutral Salt Spray Test (in accordance with PN-EN ISO 9227)

This test is one of the most gruelling tests for protective coatings. Steel plates (grade DC01) were placed in a special chamber in a highly aggressive, salty environment. Some of them were untreated, whilst others were protected by immersion in Ultimate Metal Guard Engine.

Result for unprotected (raw) steel: The first signs of destructive, red corrosion appeared on the metal after just 15 minutes of testing.

Result for the Ultimate Metal Guard Engine coating: The surface coated with our modifier effectively withstood the aggressive environment. The first signs of corrosion appeared only after 18 hours.

Laboratory conclusion: Even in the forced, inclined test position (20 degrees from vertical, which caused non-drying oil to run off due to gravity), the product maintained a strong insulating layer and effectively protected the steel surface. Moisture repellency and adhesion to metal are its key advantages.

What Do the Salt Spray Chamber Results Mean for Your Engine?

Extending the protection time from 15 minutes to 18 hours under extreme laboratory conditions is proof of the technology’s effectiveness, which, under everyday vehicle operating conditions, translates into years of trouble-free operation. The benefits for the user are immediate and long-term:

1. Elimination of the ‘Sandpaper Effect’

When micro-corrosion occurs in the engine (e.g. overnight or during a standstill lasting several days), microscopic particles of iron oxide (rust) form on the cylinder walls and shafts. Iron oxide is an extremely hard abrasive. When you start the engine, these particles enter the oil and act like liquid sandpaper, drastically accelerating wear on the engine. UMG’s powerful shield completely blocks the formation of this deadly abrasive.

2. Safe Cold Starts

The non-drying layer of the formula, which adheres to the metal, does not run off entirely into the sump. This means that when you turn the key on a cold or damp morning, the pistons and camshaft lobes do not run ‘dry’. The protective coating reduces friction during those most critical seconds before the oil pump forces oil up into the cylinder head.

3. Protection Against Corrosive Acids for Bearings

The metal alloy from which the delicate connecting rod bearings are made is highly susceptible to acids formed by the condensation of exhaust gases. Ultimate Metal Guard Engine creates a chemical barrier that neutralises this threat, protecting the bearings from the formation of micro-pitting, which often leads to a loss of oil pressure and total engine seizure.

4. A Solution for Hybrids and Cars Used Occasionally

In hybrid vehicles and cars driven over short, urban distances, the engine rarely reaches a temperature high enough to allow moisture in the oil system to evaporate completely. A highly effective anti-corrosion coating is essential in these conditions, helping to keep the engine interior in factory-clean condition, regardless of how many times the Start-Stop system activates during the day.

Technical Summary

Internal corrosion is a silent killer of compression and performance. Research from the Corr-Lab laboratory provides hard evidence that Ultimate Metal Guard Engine is not only a friction reducer but also a powerful chemical insulator. By choosing this product, you are investing in extending your engine’s service life, eliminating harmful oxides from the oil circuit and ensuring that your car is protected 24 hours a day – even when it is parked.
