Pennzoil range of fully synthetic oils starts with Platinum and Euro Platinum line. The top of the range is reserved for Ultra Platinum motor oil that is available in several viscosity grades.
It’s the most important factor in choosing the proper synthetic motor oil for your needs. If you drive your vehicle in a hotter climate or ring your motor out often, a viscosity of 10W-40 is ideal. For commuting in most cold or warm climates, a 5W-30 synthetic oil is a right choice. Finally, if you ride in an environment that could be described as arctic, a 5W-20 or even 0W-20 synthetic oil is recommended;
The labels on all kinds of synthetic oil list the specific application that the lubricant is designed for. Typical synthetic oil applications include extended performance, higher mileage, diesel engines, and motorcycles. Always double-check your vehicle’s condition before you best the best car oil for your vehicle;
Combability with Existing Oil
Before you add this oil to your ride, it’s essential to note if the product is compatible with other sorts of oil. If it isn’t, you must drain the existing oil before filling it up with the synthetic one. It’s also pivotal to consult your owner’s manual to verify which type of oil your car requires;
Each brand adds its own proprietary blend of additives to improve certain properties. For example, viscosity-index improvers work surprisingly well in ensuring that lubricant doesn’t get too thin at higher temperatures. Also, additives like detergents are efficient cleaning agents formulated to remove deposits and sludge from your motor. Find out which additives would provide the benefits you need the most before buying synthetic engine oil. The most important additives are anti-wear additives, detergents that keep the engine clean and corrosion (rust) free, dispersants and antioxidants that help the oil to flow in the oilway, friction modifiers, oil viscosity ingredients for improving oil performance and reduce oil’s thinning.
Synthetic vs. Conventional Oil
- Extends engine life – Synthetic motor oil is engineered to have a high degree of natural solvency so it can clean and remove deposits. This keeps your engine soot- and deposit-free so it can run as smoothly and efficiently as possible, as well as prolong the lifespan of motor seals and other parts;
- Maximizes engine performance – There’s a reason why high-performance vehicles and race cars all run synthetic oil — superior motor performance. Users often report that they perceive more power/torque from the motor when they utilize synthetic oil. Plus, it’s slicker than conventional oil, so it’ll definitely make your car runs smooth as glass;
- Enhances fuel mileage – Premium synthetic oil reduces the amount of friction that occurs between key engine components, therefore making your engine runs efficiently and smoothly. This improves the fuel mileage of your ride, so you’ll spend more time on the road and less time/money at the gas station;
- Flows better in hot or cold weather – The proprietary formula of synthetic motor oil makes it flow better in extreme temperatures. During winter, its resistance to viscosity breakdown allows it flows freely regardless of how cold it’s outside, so your vehicle is less likely to break down due to cold starts. Alternatively, synthetic oil works at top performance during hotter weather as well;
- Longer lifespan than conventional oil – The best full synthetic motor oil has a considerably longer lifespan than conventional oil or synthetic blends. In some situations, full synthetic oil features a change interval of up to 15,000 miles, compared to 3,000 miles for the conventional product;
- Saves you money in the long term – Even though synthetic product initially costs more per quart than conventional, it saves you dollars in the long run. You won’t only get more mileage out of motor components and save money on fuel, but you’ll also spare on less frequent oil changes.
- Full synthetic – It’s designed with a unique molecular structure and is infused with additives to provide optimal wear protection and performance for your motor. Unlike conventional oil, it’s not derived from whole, unrefined petroleum, so it’s created without any of the impurities. The best synthetic motor oil brands use a proprietary blend of anti-wear and cleaning additives to make your drive smooth as silk;
- Synthetic blend – This’s a mix of conventional oil and a brand’s synthetic base oil. It’s a conventional oil fortified with synthetic additives for better motor performance and protection. Synthetic blend doesn’t deliver the same level of protection and performance as a top-rated synthetic oil. However, a synthetic blend gives more benefits than conventional oil.
API (American Petroleum Institute)
API’s specification consists of a two-letter rating that begins with S, which stands for Service (Petrol engines), or C, which stands for Commercial (Diesel engines). The second letter appoints oil’s quality, beginning with the letter A. The further along with the alphabet, the higher the oil’s quality. The latest API standard is SN from 2011. Categories from SA to SH are obsolete. Currently in use are SJ, SL, SM, and SN.
ILSAC (International Lubricants Standardization and Approval Committee)
This committee consists of the US, European and Japanese car manufacturers. They often share specifications with API, but the focus is on emission systems and fuel economy. Standard applies to SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grade oils. The latest specification is ILSAC GF-5, ILSAC GF-6 is under development. To recognize that an oil meets ILSAC requirements, API developed a starburst certification mark.
ACEA (The Association Des Constructeurs Européens D’automobiles)
ACEA is a set of standards requested for all oils that are sold in Europe. Specification by ACEA can fall into four categories: A for petrol engines, B for diesel engines, C for engines that are catalyst compatible, and E for heavy-duty diesel engines.
OEM (Original Equipment Manufacturer)
This set of standards is developed and approved by car manufacturers and are very important for cars under warranty. Check the car manufacturer website to find out what oil brands passed OEM tests.
Synthetic oils tend to last longer than mineral oils, which is why the interval between oil changes can be prolonged. Manufacturers suggest changing the oil every 5,000 to 7,500 miles but bear in mind that these intervals may be longer or shorter, depending on multiple factors.
While mineral oils require a change every 3,000 miles, synthetic oils can run up to 7,500 miles without change. However, if your vehicle’s engine requires full-synthetic oil, you may expect it to go up to 15,000 miles between services.
As its name suggests, synthetic oil is a lubricant containing artificially made chemical compounds, including petroleum components and base material such as distilled crude oil. Synthetic oils can be used in different vehicles, from performance cars to jets. Synthetic oil manufacturers use additives to change the oil’s variance, resulting in low viscosity at lower temperatures.
Synthetic oil is typically made from a based oil (highly refined crude oil), powder additives, and carrier oils that foster an even additives distribution.
Checking engine oil is a very easy thing to do and everyone should know how to do it.
Prepare a clean towel or a paper tissue. Follow these 5 steps:
- Step #1 Park your car or truck on an even surface.
- Step #2 Turn the engine off and, if possible, wait until the engine cools down.
- Step #3 Open the vehicle hood and find an oil dipstick (usually labeled as Engine Oil and has a yellow cap) and pull it out.
- Step #4 Wipe the dipstick, put it back in the tube, and then pull it out again to have an accurate reading (this step is optional; if the engine is cold, you can skip this step).
- Step #5 Now check if there is oil between the two lines on the dipstick. Some carmakers use two dots or letters L (low) and H (high) or MIN and MAX. It would be best if there is oil near the top line or a dot that is near the top of the dipstick.
