Specifications

Liqui Moly Longtime High Tech 5W-30 motor oil utilizes synthetic technology to provide premium performance in both gasoline and diesel engines. It meets and exceeds specifications for major European, American, and Asian auto manufacturers.

The "5W" refers to the oil's viscosity or thickness when cold, with a lower number indicating better flow at low temperatures. The "30" refers to viscosity at high engine temperatures. So 5W-30 flows well when an engine is first started in cold weather, but maintains enough thickness for lubrication and protection as the engine heats up.

Some key specifications this motor oil meets:

• API SN Plus - latest API gasoline engine oil specification

• ACEA C3 - for diesel engines with exhaust gas recirculation

• BMW Longlife-04 - approved for BMW gasoline and diesel engines

• MB-Approval 229.31/229.51 - approved for Mercedes-Benz diesel engines

• VW 502 00/505 00 - approved for Volkswagen gasoline and diesel engines

The synthetic base oil and advanced additives help provide high resistance to viscosity breakdown while protecting against wear, deposits, and sludge buildup. So Liqui Moly Longtime High Tech 5W-30 is a solid choice for modern European vehicles requiring a high quality synthetic motor oil.

Pros

Liqui Moly Longtime High Tech 5W-30 motor oil has many benefits that make it a top choice for drivers.

• Provides excellent wear protection - This motor oil contains special additive packages that help prevent metal-to-metal contact in the engine. It forms a protective layer on all moving engine parts to reduce friction and wear. Users report engines lasting longer without any noticeable loss in compression.

• Clean burning - The synthetic base oils and advanced additives in Liqui Moly 5W-30 allow for more complete combustion and reduced emissions. Many customers notice less exhaust smoke and odor when using this motor oil. It helps keep the inside of tailpipes clean as well.

• Keeps engine clean - The low ash content of this motor oil prevents the buildup of sludge and deposits, especially at higher temperatures. Engines stay cleaner internally over time compared to using conventional motor oils. This contributes to extended engine life.

Cons

Liqui Moly Longtime High Tech 5W-30 motor oil does have some potential drawbacks to consider:

• More expensive than conventional oils - This fully synthetic oil tends to cost more than standard mineral-based oils. The higher price tag reflects the advanced technology and performance benefits, but buyers should factor in the added cost.

• May not be ideal for older engines - While great for modern engines, Longtime High Tech's low viscosity and fully synthetic formulation is not always recommended for older engines. The slick oil can potentially lead to leaks in engines with worn seals and gaskets. For classic cars or engines with high mileage, a conventional mineral oil may be a safer bet.

Overall the extra cost and potential leak issues with older engines are minor cons compared to the many advantages of Liqui Moly's advanced full synthetic formula. But buyers should weigh their specific needs and engine condition when choosing between synthetic and conventional oils.

Best Uses

Liqui Moly Longtime High Tech 5W-30 motor oil is ideal for modern gasoline and diesel engines, particularly those with turbocharged direct injection (TDI). Its advanced full synthetic formulation is designed to meet the demands of newer engines that run hotter and harder than older models.

The 5W-30 viscosity grade provides low temperature flowability along with high temperature protection. The "5W" indicates good cold start performance, while the "30" denotes high temperature viscosity retention of approximately 10.5 cSt at 100°C. This combination makes Liqui Moly 5W-30 a great all-season oil.

The synthetic base oils and additives help keep critical engine parts clean, reducing deposits and wear. Turbochargers and direct injection systems have tight tolerances and are especially prone to coking and buildup. Liqui Moly 5W-30 has detergents to minimize harmful deposits in these sensitive areas.

Overall, Liqui Moly Longtime High Tech 5W-30 is optimized for the unique demands of modern TDI engines. It provides exceptional protection and performance across a wide temperature range. For modern gasoline and diesel engines, particularly those with turbochargers and direct injection, Liqui Moly 5W-30 is an excellent choice.

Effectiveness

Liqui Moly Longtime High Tech 5W-30 motor oil provides excellent lubricity and wear protection for your engine. The advanced synthetic technology keeps metal surfaces separated so they don't grind against each other, reducing friction and heat.

Customers report this oil keeps engines remarkably clean compared to other brands. It minimizes the formation of sludge, varnish, and deposits, even under extreme driving conditions. The oil resists thickening so it continues to flow smoothly.

In addition, Liqui Moly Longtime High Tech has good thermal and oxidation stability. It holds up well under high temperatures without breaking down. Synthetic base oils and advanced additives prevent the oil from oxidizing and losing effectiveness over time. This allows the oil to retain its viscosity and protect your engine for extended drain intervals.

Overall, tests and customer reviews show Liqui Moly Longtime High Tech 5W-30 provides outstanding lubrication, cleans engines effectively, and has excellent thermal and oxidation stability. This high-quality synthetic oil protects your engine for the long run.

Value

Liqui Moly Longtime High Tech 5W-30 motor oil offers good value for the price. As a fully synthetic oil, it does command more of a premium than conventional oils. However, it is fairly priced compared to other leading full synthetic brands on the market.

The 5 liter jug provides a good amount of oil at a reasonable bulk purchase price. For many drivers, this larger size makes sense for the oil change intervals recommended by Liqui Moly.

When looking at other top-tier full synthetic motor oils from brands like Mobil 1, Castrol, and Valvoline, Liqui Moly Longtime High Tech holds its own. It delivers comparable performance and protection at a competitive price point. For drivers looking to step up to a high-quality synthetic, Liqui Moly represents a cost-effective option.

While not the absolute cheapest synthetic available, Liqui Moly Longtime High Tech offers good value by balancing quality, performance, and fair pricing. Drivers get robust protection and long oil change intervals without overpaying. For these reasons, it remains cost competitive with other premium synthetics.

Compatibility

When it comes to motor oil, it's always best to check the manufacturer recommendations for your specific vehicle before choosing which oil to use. However, Liqui Moly Longtime High Tech 5W-30 is formulated to be compatible for use in most modern engines.

The advanced synthetic technology works well across a wide range of vehicles and driving conditions. It meets or exceeds the specifications for major manufacturers such as BMW, Mercedes Benz, Volkswagen, Porsche, GM, and Ford. So unless your owner's manual states otherwise, Liqui Moly Longtime High Tech 5W-30 can generally be considered a safe choice.

The key is the oil's 5W-30 viscosity rating, which provides a balance of viscosity across hot and cold temperatures. This versatility makes the oil suitable for many types of engines. The synthetic base also offers enhanced protection properties compared to conventional mineral oils.

Just be aware that some older engines or high-performance applications may call for specific oil requirements. As always, defer to the recommendations in your owner's manual as the final authority. But for most modern vehicles, Liqui Moly Longtime High Tech 5W-30 is designed to provide excellent all-around performance and protection.

Environmental

The Liqui Moly Longtime High Tech 5W-30 motor oil is designed with the environment in mind. It features a fully synthetic formula that requires less frequent oil changes compared to conventional oils. This reduces waste and environmental impact.

The oil is also formulated as a Low-SAPS (sulfated ash, phosphorus and sulfur) product. This means it has lower levels of these chemicals that can negatively affect emissions control systems. Using Liqui Moly Longtime High Tech helps reduce overall vehicle emissions and environmental impact. Its advanced formula allows it to provide extended protection between changes without compromising on emissions.

For drivers looking for an oil that performs well and also considers the environment, Liqui Moly Longtime High Tech is an excellent choice. Its synthetic technology and Low-SAPS formulation make it a more eco-friendly option than conventional motor oils.
