As winter rolls in and the temperature drops below freezing, it’s important for vehicle owners to choose the right motor oil for such conditions. A synthetic oil with the right viscosity can improve engine protection and performance in the cold winter months. Sean Nguyen, Pennzoil’s technical scientist and automotive lubricant specialist, told Counterman that it’s important to consider an oil’s ability to flow effectively in cold temperatures.
“In the winter, that’s when the oil is the slowest or the densest, and it takes time for the oil to get from the reservoir, from the oil pan to get up to the cylinder heads,” explained Nguyen. “Those times are precious. 90% of wear happens in the first 90 seconds of an engine start.”
When your customer is looking for motor oil in winter, you’ll want to suggest high-performance synthetic multi-weight oils such as Pennzoil Platinum. These oils, with a SAE 0W-xx or 5W-xx rating, are specifically formulated to remain fluid at low temperatures. That ensures quick lubrication during the cold start, which comes in handy for vehicles exposed to the elements without the protection of a heated garage.
Conventional oils, especially those designed for warm temperatures, often contain impurities and waxy substances that can make them less effective in winter weather. Nguyen said synthetic oils are more homogeneous and better refined, allowing them to flow more efficiently in extremely cold temperatures. That cuts down on the time an engine spends running without proper lubrication.
A common misconception among customers is that thicker oil performs better in winter. They assume using a higher-viscosity oil, like 5W-30 or 10W-40, will help their engine perform better because it seems logical that thicker oil would be more durable in extreme conditions. Nguyen says this is not the case.
“Make sure that second number (the oil’s viscosity at normal engine temperature) is correct. Don’t go to a thicker number because you think it is going to make the oil in your engine work harder.
For example, I recommend that you use a SAE 0W-20 all year round for engines that call for a 5W-20. The 20 gives you the protection that you have all year, winter or summer, because the engine is going to see whatever temperature it sees based on the thermostat, while the 0W will flow much better in those cold morning starts.”

This warm-up time ensures the oil flows effectively, protecting the engine from wear and tear during those dry starts. That, along with thinner oil weight, will provide faster oil flow to critical areas of the engine.
The challenge for counter professionals: How to effectively communicate the benefits of low-weight synthetic oils for winter? Nguyen says simplifying the technical language and connecting it to a customer’s needs can go a long way. He suggests highlighting the long-term savings and benefits of synthetic oils, like an improvement in fuel efficiency, maximized engine protection and excellent performance offered by oil like Pennzoil Platinum. It also doesn’t hurt to explain how the composition of synthetic oil keeps it stable in cold conditions, improving overall longevity and performance.
“Do you want to keep your car longer?” Nguyen recommends asking the customer. “Do you want it to perform when you want it to? High quality synthetic oils will do that.”

Autonomous driving, often referred to as self-driving technology, aims to automate the driving experience entirely, freeing drivers from the need to control the vehicle. This technology is being developed in stages, with increasing levels of autonomy, as defined by the Society of Automotive Engineers (SAE):
Levels of Autonomous Driving
Level Description 0 No automation. The driver is fully in control of the vehicle at all times. 1 Driver assistance. The vehicle provides limited assistance with tasks such as steering or accelerating, but the driver remains primarily in control. 2 Partial automation. The vehicle can control both steering and acceleration/deceleration under certain conditions, but the driver must remain alert and ready to take control at any time. 3 Conditional automation. The vehicle can perform all driving tasks under specific conditions, but the driver may still need to intervene in certain situations. 4 High automation. The vehicle can perform all driving tasks under most conditions, and the driver may be able to disengage completely. 5 Full automation. The vehicle can perform all driving tasks under all conditions, and there is no need for a human driver. Key Technologies Enabling Autonomous Driving
The development of autonomous vehicles relies on a complex interplay of various technologies:
Sensor Fusion: Combines data from multiple sensors like cameras, radars, and lidars to create a comprehensive and accurate picture of the vehicle's surroundings.

High-Definition Mapping: Provides detailed maps of the environment, including road layouts, lane markings, traffic signs, and other relevant information. Vehicle Control Systems: Actuators and control systems enable the vehicle to execute commands from the autonomous driving system, such as steering, accelerating, braking, and changing lanes. Current State of Autonomous Driving
While fully autonomous vehicles (Level 5) remain a long-term goal, significant progress has been made in developing and deploying lower levels of autonomy.
Advanced Driver-Assistance Systems (ADAS): Features like adaptive cruise control, lane keeping assist, and automatic emergency braking 1 are becoming increasingly common in new vehicles, representing Level 1 and Level 2 autonomy. Robotaxis and Autonomous Shuttles: Several companies are testing and deploying autonomous vehicles in controlled environments, such as designated areas within cities or university campuses. These vehicles often operate at Level 4 autonomy, with limited human supervision. Commercial Applications: Autonomous trucks and delivery vehicles are being developed and tested for logistics and transportation applications, offering the potential for increased efficiency and reduced costs. Challenges and Concerns
Despite the significant progress, several challenges and concerns remain on the road to fully autonomous driving:
Technological Limitations: Current sensor technologies and AI algorithms still struggle to handle complex and unpredictable scenarios, such as adverse weather conditions, construction zones, or interactions with pedestrians and cyclists. Safety and Liability: Ensuring the safety of autonomous vehicles and determining liability in the event of accidents are critical concerns that need to be addressed through robust testing, validation, and regulatory frameworks. Public Acceptance: Gaining public trust and acceptance of autonomous vehicles will require addressing concerns about safety, job displacement, and the potential for misuse of the technology. Infrastructure: Widespread adoption of autonomous vehicles will necessitate significant investments in infrastructure, including intelligent transportation systems, high-definition maps, and communication networks. The Transformative Impact of Connectivity and Autonomous Driving
The convergence of connectivity and autonomous driving has the potential to revolutionize the transportation sector and society as a whole:
Improved Safety: By eliminating human error, which is a leading cause of accidents, autonomous vehicles have the potential to significantly reduce fatalities and injuries on the roads. Studies suggest that autonomous vehicles could reduce traffic fatalities by up to 90%.

link hidden, please login to view Cathie Wood of Ark Investment Management said Tesla’s move into the more profitable business of self-driving taxi platforms would boost its share price by about 10 times. That echoes years of optimism about Tesla’s self-driving business.
Image source: link hidden, please login to view
Wood believes the self-driving taxi ecosystem will be worth $8 trillion to $10 trillion globally, with platform providers such as Tesla taking half of that. Speaking on the Tiger Money podcast, Wood revealed that investors are shifting the way they value Tesla, not just as an electric car maker, but also the potential of its self-driving taxis. Wood said: “The autonomous taxi platform is the fastest growing AI project today, and Ark is primarily valuing it based on Tesla’s autonomous driving potential. If we’re right, there’s plenty of room for Tesla’s stock price to grow.” Optimism over Tesla’s efforts to bring self-driving taxis to market has helped its shares recover a 43 per cent fall in the year to April 22. Wood said the self-driving taxi network will provide A “winner-takes-all” opportunity, with providers that can get passengers from point A to point B in the safest and fastest way winning the lion’s share of business. She added that autonomous taxi network providers will be able to capture 30 to 50 percent of the revenue generated by fleet owners on the platform, resulting in “growing explosive cash flows” and profit margins of more than 50 percent. This is different from the “make and sell” or “one-off” business model of traditional car manufacturing. “We think people are missing that: the size of the opportunity, the speed of expansion, and how profitable it will be,” Wood said. She expects Tesla to dominate the U.S. self-driving taxi market. Last week, Tesla had a weighting of more than 15% in the $6.5 billion Ark Innovation ETF. Wood said the fund has taken some profits off Tesla, allowing the stock to trade above its normal cap because they believe Tesla is about to reveal more information about its self-driving taxi project. According to a Bloomberg report on July 18, Tesla has delayed the launch of its self-driving taxi by two months to October, originally scheduled for August, to give the team more time to produce more prototypes. The news sent Tesla shares down 8.4%, their biggest one-day drop since January. But Wood doesn’t mind. “We may be closer to the self-driving taxi opportunity than we are further away, and Musk may want to do better and think it is possible by October,” Wood said. Fang’s valuation model does not yet take into account Tesla’s potential in China or in humanoid robotics and energy storage. In April, Tesla, which reached a mapping and navigation deal with Chinese tech giant Baidu Inc and met data security and privacy protection requirements, has already received approval in principle from Chinese officials to deploy its self-driving assistance system to China, the world’s largest auto market.
