Superior Cleaning Comparison:

Pennzoil Ultra Euro L contains a feature that no other oil has: its engine cleaning power. Yes, it will keep your engine and its parts clean 40% more than an industry standard because it prevents the deposition of sludge and other waste.

It’s also due to the active cleansing detergents present in it. It has been said that Ultra Euro L is the solution to potential stubborn deposits.

Keeping in view, Ultra Platinum also protects friction, sticky sludge deposits, and engine parts damage, so the components and overall performance cannot be affected. In this section, both oils protect the engine and parts in the same direction.

Purification Techniques and Technologies Comparison:

Both engine oils are produced by the PurePlus technology and converted into high-quality motor oil by natural gas. Thus, both are formulated with the PurePlus technology, so the purification and preparation methods are the same.

In PurePlus technology, the natural gas is converted into high-quality motor oils by revolutionary processes, which helps to make 99.5% of pure oil compared to the general crude oil.

Shell is constantly using this technology to make better Pennzoil products with enhanced performances. It has been observed that the use of PurePlus ensures no remains of impurities.

Additives Comparison:

The primary aim is to protect the engine from stubborn deposits and unhealthy performance. Whenever the engine revolves or circulates, the crude and waste sludge will produce.

To protect engine health from such wastes, the shell is now using high-quality additives.

The additives can be dispersants, detergents, antioxidants, anti-wear, corrosion inhibitors, modifiers, and much more.

The case studies on the efficiency of motor engines and oils have clearly shown that additives have a leading role. The overall health performance is dependent upon it.

For now, Pennzoil Ultra euro L is using a mixer of phosphorus and sulfur as an additive. This highly enhances combustion and lubrication and even works perfectly under extreme temperature conditions.

On the other hand, Ultra Platinum contains molybdates and nitrates as an additive. These are especially corrosion inhibitors and that efficiently slow down the cathodic reaction.

Also, it’s helpful in creating limitations in the diffusion of reducing species to the metal surfaces.

Engine Performance Comparison:

The engine performance will be decided after going through the various steps.

Catalytic Converter Performance

Catalytic converters can be highly affected by toxic components present in engine oils. These components are generally added to while we are choosing additives.

Similarly, if we go through the additives of Pennzoil Ultra Euro L, the additives used are the mixer of phosphorus and sulfur, which is high in toxicity. The phosphorus is present in 823 ppm amounts, while sulfur is present at 0.29%.

Thus, high vapors may be formed when temperature leads, harming the catalytic converter.

While additives of Pennzoil Ultra Platinum involve corrosion inhibitors, so they perform well in maintaining catalytic converters.

Avoiding Waste Sludge Comparison

The engine oils, upgraded by adding suitable additives, surely avoid the surplus of sludge and waste materials. These are such crude wastes that decrease the efficiency of the overall engine and damage the components.

Both of these oils are made with additives that perform well in avoiding wastes and sludges. Based on this, if you want to select engine oil, both are best, but your preference will be the one that shows compatibility with your vehicle.

Seals Protection of Engine Comparison

The engine seal has been declared the biggest loss because it disrupts all other functions of the engine. And if it is not tackled for some time, it will undoubtedly remain incurable.

There are several reasons why this can be sealed, but good engine oil removes almost all.

Observations show that the biggest cause is an accumulation of sludge which can be avoided by the strong additives present in the engine oil. There are additives present in both of them. But the preferable has non-toxic additives.

Again, Pennzoil Ultra Platinum catches a win.

Volatility Score Comparison

The volatility of any engine oil decides its life cycle after how much time you need to change the oil again. Simple, low volatility engine oils are best.

Here’s the truth!
