These motor oils are used for only gasoline type of engines. Both of them are wholly synthetic. Havoline Pro-DS’s center of focus is cleansing of engine meanwhile Pennzoil Platinum generally emphasizes more on cold startups.
Pro-DS provides remarkable performance in the cleaning of engine because of its enormous detergent and dispersant quantities. This oil provides high protection against rapid and early oil burn-off. The presence of anti-wear additives in noticeable amounts also assists to protect the engine from wear.
This oil possesses high kinematic viscosity to ensure dominant performances during extremely high temperatures meanwhile a higher viscosity index also helps to retain the oil’s viscosity.
On the contrary, Platinum provides excellent performance of catalytic converter due to its lower ash build-up. The presence of an immense number of anti-wear additives helps to protect the engine from wear and tear. To minimize the sludge formation, detergents along with dispersants are present in good numbers.
This oil is also considered good for providing cold starts during winters. The higher base additions make sure to lower the frequency of exchanging the oil. Moreover, its lower price also makes it more economical and budget-friendly.

Contrasting viscosity of oil
The difficulty in the oil flow is termed as Kinematic Viscosity. The oil will perform better at elevated temperatures if it possesses a higher kinematic viscosity. The index of viscosity is defined as the oil’s ability to retain its viscosity when there is any switch in temperature.
The oil having a higher viscosity index will undergo lower variation in its kinematic viscosity upon temperature elevation. The working of oil in lower temperatures is characterized by its pour point, which is actually the lowest temperature beneath which it stops flowing.
Pro-DS is more dominant when it comes to engine performance at standard and higher temperatures. It is a consequence of its higher kinematic viscosity at both 40 o C as well as 100 o C. Its higher viscosity index also provides this oil an edge to keep up its viscosity when the temperature increases from normal to high.
Platinum working is better in chilly regions because of its lower pour point temperature compared to that of its counterpart.

Interval of Oil Interchanging Comparison
Acids are formed as a result of oil combustion. These acids are extremely harmful as they cause engine corrosion. Alkaline additives are introduced to the oil to lower this issue.
Their purpose is to neutralize these acids. The quantity of these alkaline additives is normally measured in TBN.
A higher TBN oil shows greater base addition and thereby provides a longer interchanging duration.
Pro-DS possesses these bases in lower numbers as it has a relatively lower TBN. This oil, as a result, provides a lower oil replacement duration than that of its peer. It is recommended to change the oil after a distance between 3,000 to 7,500 miles.
The base concentrations in Platinum are higher in comparison therefore it provides a longer interval of oil changing. The span of interchanging this oil is between 7,500 to 10,000 miles.

Comparison in terms of Catalytic Converter Functioning
The performance of the catalytic converter gets affected by the ash build-ups. This ash is devised as a result of the reaction between the reacted oil with some anti-wearing compounds specifically zinc along with phosphorus.
This ash launches into the converter and seizes it. This ultimately restricts the catalytic converter to provide maximum output, thereby being less effective.
The higher the concentrations of these compounds, the lower will be the converter’s efficiency.
Pro-DS holds these anti-wear agents in greater numbers, therefore, will produce relatively more ash residue. That’s why it is behind its peer in terms of catalytic converter functioning.
Meanwhile, Platinum because of its lower quantities of these compounds, produces lesser ash and consequently gives more efficient catalytic converter performances.

Comparing build-ups of Sludge
An overall higher concentration of detergent additives in Pro-DS makes it superior to its rival regarding engine cleansing. Calcium is found to be in the majority numbers in this oil. On the other hand, quantities of magnesium are higher in Platinum. Silicon, which is an anti-foaming agent, is present in slightly higher amounts in Pro-DS.
|Comparing oils (5W-20)||Quantity of Calcium (ppm)||Quantity of Sodium (ppm)||Quantity of Magnesium (ppm)||Quantity of Silicon (ppm)|

|Pennzoil Platinum||982||< 5||684||4|
Prior oil Combustion Comparison
The premature burning of oil decreases fuel efficiency. The early burn-off is dependent on the number of light molecules found in the oil. This is because of the reason that at higher temperatures these molecules won’t be able to hold out and will vaporize quickly, increasing the rate of evaporation.
So, if the oil has these molecules in higher numbers, it will reach its flashpoint at a lower temperature.
The comparison regarding pre-burning protection is very close between these oils. However, Pro-DS due to its faintly higher flashpoint temperature takes the lead in this regard.
The greater flashpoint indicates that it contains a slightly lower number of lighter molecules.
Platinum, on the other hand, has relatively higher volatility, because of its higher lighter particles concentrations, therefore it reaches its flashpoint at a lower temperature.

Shielding from Engine Wearing Comparison
These oils are equally compatible when it comes to the protection from degradation of the engine. The concentration of primary anti-wearing compounds which are zinc and phosphorus is comparatively high in Pro-DS. However, Platinum contains secondary anti-wearing additives including boron, molybdenum, and titanium in comparatively higher amounts. The overall concentrations of these additives are faintly higher in Platinum, enabling it to give more protection against wear and tear.

Difference in Pricing
The price of Platinum is lower than its competitor. The 5 L container of the oil is around 24.98 US Dollars. This makes this oil more affordable because of its cheaper price.
On the contrary, Pro-DS is more extravagant than its peer. A similar 5 L container is available at a price of about 35.08 US Dollars.
However, the overall dominant working of oil during higher temperatures as well as better cleaning of engine compensate this high price.
- Both motor oils can be utilized in only gasoline engines and they are completely synthetic.
- Platinum is ahead of its competitor in terms of catalytic converter efficiency.
- The higher concentrations of detergents in Pro-DS makes this oil better in engine cleaning.
- Platinum provides a superior safeguard against engine wear and tear.
- The performance of Pro-DS is more dominant during higher temperatures.
- Platinum needs to be changed after longer duration because of its higher base additions.
- The price of Pro-DS is greater than that of its peer.
