Pennzoil Q & A

PRODUCT SPECIFIC / TECHNICAL 1. What are the differences between Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology and Pennzoil Ultra Platinum™ Full Synthetic motor oil with PurePlus™ Technology? Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology is a very high performing full synthetic motor oil. However, Pennzoil wanted to test the boundaries […]

Putting the Simple Back into Viscosity

by John Sander, VP Technology, Lubrication Engineers Inc. abstract Simply stated, viscosity is defined as the internal resistance of a fluid to flow. That doesn’t sound too difficult, does it? Unfortunately, new temperature, speed and pressure demands on lubricating fluids have changed over the years, resulting in several different measurements and classifications being created to […]

What’s in your Motor Oil

To a formulator, a motor oil is a complex blend of 10-15 ingredients carefully balanced and tested to meet the industry specifications and market claims. To a blender it can be as simple as mixing three liquids together and filling it into bottles. And to the consumer it is, for the most part, a mysterious […]

Motor Oil University Final Exam

question 1 While starting up your car at 75°F, mid-winter in Florida, which of these synthetic oils provides the least startup resistance, minimal battery and starter motor load? [A. 0W-20] [B. 0W-30] [C. 0W-40] [D. 0W-50] [E. They are all exactly the same] The correct answer is A- 0W-20 The correct answer is A- 0W-20 […]

Motor Oil University Mid-Term Exam

At normal operating temperature, 212°F, a straight 30 grade oil has a viscosity of how many centiStokes? A. 3 B. 6 C. 10 D. 20 E. 30 The correct answer is C- 10 cS The correct answer is C- 10 cS While racing at 95°F, mid-summer in Florida, which of these synthetic oils gives the […]

Motor Oil 201 – Chapter Ten – The Graduate

I am going to bring up the constant flow pump concept. First, it goes back to the principal that doubling the pressure of the same grade oil does not exactly double the flow but it is close. Also doubling the RPM for the same reason does not exactly double the flow but again it is […]

Motor Oil 109 – Chapter Nine – Let’s Start Over

We have seen that 0W-30, 5W-30, 10W-30 and straight 30 grade oils all have the exact same viscosity at 212° and 302°F. What about startup viscosities? Do 0W-20, 0W-30 , and 0W-40 all have the same viscosity at a 75°F startup. The answer is no. The SAE J300 standard allows for this discrepancy. Here are […]

Motor Oil 108 – Chapter Eight – Odds And Ends

I have some stories that I collected. First, my architect drives a big SUV. He was running with Mobil 1 brand 15W-50. He changed it to Pennzoil Multi-grade (mineral oil based, non-synthetic, cheap) 5W-20 at my suggestion. His gas mileage went from 10 to 13 MPG around town. What really impressed him the most was […]

Motor Oil 107 – Chapter Seven – What Is The Terminology From SAE And API?

Many think that the “W” in 10W-30 means “winter”. Two series of viscosity grades are defined in Table (1): (a) those containing the letter W and (b) those without. Single viscosity grade oils with the letter W are defined by maximum low temperature cranking and pumping viscosities and a minimum kinematic viscosity at 100°C. Single […]
