Product Overview

Pennzoil Platinum full synthetic SAE 5W-20 motor oil is uniquely engineered from our revolutionary PurePlus gas-to-liquid technology, which is a patented process that converts pure natural gas into a high quality, full synthetic base oil. Our high-quality base oil is 99.5% pure, contains fewer impurities than base oils made from crude oil, and when combined with our advanced additive technology, creates one of the best formulations in our Pennzoil portfolio. Pennzoil Platinum full synthetic SAE 5W-20 motor oil is licensed and meets the vehicle warranty requirements of GM's dexos 1 Gen 2 specifications that are set forth to meet today's modern engine technologies. This means that our Pennzoil Platinum full synthetic products meet the stringent requirements of leading car manufacturers. Why does this matter? Modern engine technologies have evolved over the years and today's engine parts have reached an unprecedented level of fine manufacturing tolerances which require a high-quality engine oil to help provide complete engine protection. This includes protection against abnormal combustion phenomenon like low-speed pre-ignition observed in modern turbocharged gasoline direct injection (TGDI) engines.
  • Engineered to provide a high-quality base oil using our revolutionary PurePlus gas-to-liquid technology in combination with a high performance additive system
  • Helps protect against the effects of low speed pre-ignition (LSPI) in modern turbocharged engines
  • Provides better fuel economy which helps you drive an extra 550 miles per year vs a dirty engine
  • Offers unsurpassed wear protection by keeping engine parts from coming into contact
  • Delivers outstanding piston cleanliness, keeping pistons up to 50% cleaner than required by the toughest industry standards (based on Sequence IIIH engine test results)
  • Protects against loss of horsepower by helping to protect your engine against wear and deposit formation
  • Excellent Temperature Performance

Still Skeptical??
Been using this motor oil for my last 4 oil changes. Very impressed by the smoothness of my motor and dosen't burn-off or stink after a couple thousand miles like some top-end comparator oils. If it's good for the 7.6L Twin Turbo V8 of the Venom F5, it's good enough for me!

    Very please
    I've changed my own oil now for near 30 years. I've never been let down by Pennzoil. I've tried using the competition in a silver bottle but it made my vehicle engines sound very loud. While I can understand it's protection may be on par to Pennzoil I could do without the valve clatter, so I went back to the tried true and trusted Pennzoil. I won't bother changing to other brands anymore.

            Great quality for price
            I put 10W30 Platinum Full Synthetic in my 95 Trans Am with a 5.7L LT1. I saw about a 0.9 mpg average increase over a 2000 mile period. I also noticed a gain in compression, which could also be because I switched from 5W30 to 10W30. I'm not a good enough driver to notice any power difference claimed by Pennzoil. After 5000 miles I did an oil analysis and 72% of anti-wear additives were still present in the sample.

              Great oil!
              I started using Pennzoil platinum 2 years ago and my engine is much quieter on start up and runs much smoother and quieter when hot. Previously I was using Mobil 1 which isn’t the Mobil 1 motor oil of 20 years ago.

                Great Oil, Great Price
                I use Pennzoil Platinum 0W-20 in my 2014 Chevrolet Malibu 2.5L. I personally love the science behind the oil, like it being created from natural gas and that Pennzoil offsets 100% of the carbon emissions from creating the oil. Keep it up Pennzoil/Shell. I love your products, whether it's oil or gasoline. Just make sure you shake the oil VERY well before putting it in your car because the additive package falls to the bottom of the container after a while, and obviously you want that going in the car. It'll look like a sandy type material on the bottom of the container. *Quick note to consumers, ensure your oil filters bypass PSI for the bypass valve is correct for your particular engine. Mobil told me their filters were compatible with my car, but after some research it turned out that was completely wrong and GM specifically says that it is not because Mobil has PSI of 12-15 and GM says my engine requires a bypass PSI of 22. Don't trust all manufacturers to know what they are talking about.
