Comma Syner-G Full Synthetic 5W40 - 1 Liter ⚫ Review 🏆

Comma is a well-known brand for high-performance motor oils based in the UK. They offer a range of synthetic and semi-synthetic oils engineered to meet strict specifications set by major auto manufacturers.

The Syner-G line represents Comma's premium full synthetic motor oils, designed for ultimate engine protection. Syner-G oils are formulated with advanced additive technology and synthetic base oils to provide exceptional wear protection, thermal stability, and fuel economy benefits.

Within the Syner-G line, the 5W40 viscosity grade is intended for modern gasoline and diesel vehicle engines. The 5W-40 designation refers to the oil's viscosity or thickness at cold and hot temperatures. The "5W" means the oil flows well at cold winter temperatures for easier starting and fast lubrication at startup. The "40" refers to the viscosity at high operating temperatures, where a thicker oil film is needed for protection between moving engine parts. Overall, 5W40 oils like Syner-G provide year-round protection and performance.

Specifications and Approvals

Comma SYN1L 5W40 motor oil is formulated to meet or exceed the latest specifications from major automakers. It carries approval from BMW for Longlife-01 and Longlife-04 engines, approval from Mercedes-Benz for 229.5 and 229.3 engines, and approval from Volkswagen for engines requiring 504 00 and 507 00 oils.

The oil meets the ACEA C3 specification for use in gasoline and diesel engines with after-treatment devices that require a low SAPS oil. It also meets ACEA A3 for high performance gasoline and direct injection diesel engines. The advanced full synthetic formula provides exceptional protection and performance for modern engines running under very demanding conditions.

Key Performance Features

Comma SYN1L Syner-G 5W40 is a fully synthetic motor oil designed to provide excellent all-round performance and protection for petrol and diesel engines. It combines a range of advanced additives with a synthetic base oil to deliver key performance benefits:

• Full Synthetic Formula: Being fully synthetic allows Syner-G to flow easily when cold for faster lubrication at start up while also maintaining viscosity at high temperatures. The synthetic base oils have higher purity compared to conventional oils for improved performance.

• Low Viscosity for Cold Starts: With a 5W viscosity grade, Syner-G flows rapidly from the oil pump to critical engine components when starting in cold weather conditions. This allows faster lubrication to prevent wear during start up.

• High Heat Resistance: The advanced formulation resists thermal breakdown far better than conventional motor oils. It maintains viscosity to continue protecting your engine even under sustained high temperature driving conditions.

• Detergent and Dispersant Additives: Syner-G contains detergent and dispersant additives to keep engine internals extremely clean. It neutralizes acids while preventing the formation of deposits, sludge and varnish. Dispersants prevent soot and carbon particles from agglomerating to form larger wear-causing particles.

Real World Performance

Customers have generally found Comma SYN1L provides excellent real world performance in a wide range of vehicles. Many report this oil helps reduce engine noise compared to other oils, resulting in a quieter and smoother driving experience.

The advanced synthetic formula seems to do a good job minimizing oil consumption between changes. Several customers moved to Comma SYN1L after experiencing high oil consumption with other brands, and found it significantly reduced their top-up frequency.

In terms of engine protection and longevity, the feedback is also positive. There are reports from customers using Comma SYN1L in vehicles with over 100k miles without any major issues arising. The oil appears to do a good job keeping high mileage engines clean and running smoothly.

Some note improvements in fuel economy after switching to Comma SYN1L, which they attribute to the low viscosity and synthetic formulation reducing friction. While the gains are generally marginal, it seems the oil lives up to its promise of maximizing engine efficiency.

Overall, real world reports suggest Comma SYN1L provides excellent all-round performance across a variety of gasoline and diesel vehicles. The combination of advanced additives and synthetic base oils seems to deliver great protection, efficiency, and longevity. For drivers looking to get the most out of their engine, this oil is a top choice.

Oil Change Interval

Comma recommends an oil change interval of up to 15,000 miles or 12 months with Syner-G, depending on your driving style and conditions. This interval is possible due to the synthetic base oils and advanced additive package, which provide exceptional thermal stability and resistance to oxidation.

However, oil change intervals can vary significantly based on your specific driving habits and vehicle condition. More frequent oil changes may be required if you frequently drive in stop-and-go traffic, tow heavy loads, drive in extremely hot or cold climates, or take many short trips without allowing the engine to fully warm up. On the other hand, you may be able to extend the interval if most of your driving is highway miles in ideal conditions.

The best way to determine your ideal oil change interval is to get an oil analysis done periodically. This can reveal if the oil is still within good condition after a certain mileage, allowing you to maximize the interval while avoiding potential engine wear. An analysis can also detect any abnormalities requiring more frequent changes. In general, carefully following the manufacturer's recommendations is a safe approach.

Available Sizes

The Comma SYN1L Syner-G Full Synthetic 5W40 Motor Oil is available in a few different sizes to suit your needs.

Pros

Comma SYN1L Syner-G 5W40 motor oil has several advantages that make it a good choice for certain vehicles and driving conditions.

• Meets manufacturer specifications for many European luxury brands including Porsche, Mercedes-Benz, BMW, Volkswagen, and Audi. This oil is approved for use in vehicles that recommend 5W40 viscosity grade oils meeting ACEA C3 and API SN engine oil standards.

• Features excellent cold flow properties and low viscosity ratings, allowing for easier cold weather starting and faster lubrication at start-up. The 5W winter grade ensures good pumpability at low temperatures.

• Utilizes a combination of synthetic base oils and advanced additives that provide strong resistance to oxidation at high engine temperatures. This oil withstands heat and resists thickening, helping prevent sludge and varnish deposits.

• Contains anti-wear additives like zinc dialkyldithiophosphate to protect against wear of internal components under high load conditions. Can help extend engine life.

• Has a lower volatility compared to conventional oils, reducing oil consumption and limiting the need for top-offs between oil changes.

Cons

Comma Syner-G is not as widely available as major brands like Castrol, Mobil 1, and Shell in some areas. You may have to search around more to find it locally. The higher performance synthetic formula also makes it more expensive than basic conventional motor oils. While the extra cost is worth it for the additional protection and longer change intervals it enables, it still costs noticeably more than standard mineral oils. The 5 liter jug retails for around £35-40, making it over £7 per liter. For some owners seeking the cheapest oil to simply top off or change, the cost could be prohibitive. However, for most drivers prioritizing engine protection and performance, the premium price is justified by the quality of Comma's Syner-G. But availability and price may still be drawbacks compared to big name brands.

Conclusion

Comma Syner-G Full Synthetic 5W40 Motor Oil is a top-tier engine oil that delivers exceptional performance and protection. It meets or exceeds the latest standards from major European manufacturers like VW, Mercedes Benz, BMW, and Porsche.

The fully synthetic formulation utilizes advanced Group IV PAO base oils and additives that provide superior resistance to thermal breakdown and deposit formation.
