The Smith & Allan 0W-30 Fully Synthetic Engine Oil reviewed here is one of their premium offerings for modern diesel and gasoline engines. Let's take a closer look at the features and benefits of this low viscosity synthetic motor oil.

Product Overview

Smith & Allan 0W-30 Fully Synthetic Engine Oil is a high-quality motor oil designed for gasoline and diesel engines. It utilizes a fully synthetic base oil formulation and has a 0W-30 viscosity grade, making it a low viscosity oil intended for use in cold temperatures.

The 0W refers to the winter or cold temperature rating, with 0 being the lowest and indicating excellent cold flow properties. The oil can flow readily even in frigid temperatures below -30°C.

The 30 refers to the viscosity rating at high temperatures. A lower viscosity rating like 30 allows the oil to flow more easily when the engine is hot, reducing friction and improving fuel economy. This 0W-30 grade makes the oil versatile for variable temperature conditions.

The fully synthetic base stock gives the oil superior resistance to oxidation and thermal breakdown compared to conventional mineral oils. It helps minimize sludge build-up and provides excellent protection across a wide temperature range.

Overall, Smith & Allan 0W-30 Fully Synthetic Engine Oil is engineered for newer gasoline and diesel engines requiring a high-quality, low viscosity, fuel-efficient motor oil. The 0W-30 grade and fully synthetic formula offer advantages over conventional SAE oils.

In addition to the 0W-30 variant, Smith & Allan also offers the Smith & Allan 10W-30 Mineral Engine Oil - 5 Litres. This mineral engine oil is designed for a range of applications and provides reliable protection for older engine designs. With its 10W-30 viscosity grade, it offers good performance in both low and high temperature conditions while helping to maintain engine cleanliness. Ideal for both gasoline and light-duty diesel engines, this option is perfect for those seeking a dependable, cost-effective motor oil solution.

Intended Use

The Smith & Allan 0W-30 Fully Synthetic Engine Oil is designed specifically for PSA B71 2312 engines, which are found in certain Peugeot, Citroen and DS Automobiles diesel vehicles. This oil meets the latest PSA B71 2312 specification required for these engines.

The PSA B71 2312 specification sets stringent standards for low viscosity, low ash content and fuel economy benefits. It is mandatory for PSA group vehicles with diesel particulate filters and requiring low SAPS (sulfated ash, phosphorus and sulfur) oil. Using the correct oil that meets this spec is critical to ensure proper performance and protection of the engine and emission control systems.

This 0W-30 viscosity grade provides easier cold starting and faster lubrication at low temperatures along with better fuel economy compared to higher viscosity oils. The "0W" indicates a very low viscosity rating for cold temperature (winter) performance. At the same time, the 30 viscosity grade offers stable lubrication at normal engine operating temperatures. Overall an excellent choice for PSA B71 2312 compliant vehicles.

Additionally, for those looking for a more traditional option, the Smith & Allan Classic SAE 30 Non Detergent Mineral Engine Oil - 1 Litre is a great choice. This non-detergent mineral oil is formulated for older engines that require classic lubrication solutions. It provides excellent protection and is designed to minimize oxidation, ensuring prolonged engine life. Ideal for vintage and classic cars, it helps maintain the integrity and performance of engines that do not require modern detergent oils.

Benefits

Smith & Allan 0W-30 Fully Synthetic Engine Oil offers several key benefits for your vehicle's engine and performance.

One of the main benefits is improved fuel economy. The 0W-30 viscosity grade provides low resistance, allowing the oil to flow smoothly and efficiently. This helps reduce friction and pumping losses in the engine, enabling better fuel efficiency. The fully synthetic formula is designed to provide maximum energy conservation, so you can get more miles per gallon.

In addition, the 0W-30 grade offers excellent low temperature viscosity and pumpability. It flows easily even in very cold temperatures, providing rapid lubrication at startup to protect critical engine components. The low viscosity helps minimize engine drag during cold weather, further enhancing fuel economy. So this oil is great for cold climate driving.

The fully synthetic base oils also have higher resistance to oxidation at high temperatures. This prevents viscosity breakdown and helps maintain fuel efficiency benefits even under severe driving conditions.

So in summary, Smith & Allan 0W-30 Fully Synthetic provides fuel efficiency, cold weather performance, and high temperature stability - all benefits for your engine's performance and your wallet.

Drawbacks

One potential drawback to consider with Smith & Allan 0W-30 Fully Synthetic Engine Oil is the higher cost compared to conventional motor oils. Fully synthetic oils like this generally cost more upfront, which may be prohibitive for some consumers. The improved performance and potential long-term savings from extended drain intervals can offset the higher initial price, but the increased cost is still worth factoring in. For buyers on a tight budget or with multiple vehicles to maintain, a synthetic oil may not make the most economic sense. The price premium also means you don't want to use this oil carelessly, like in older high-mileage engines where the benefits would be minimal. While the quality and results of a full synthetic like this Smith & Allan oil can justify the extra expense for many drivers, it's important to weigh the price difference against your specific needs and situation. The upfront cost is realistically the biggest potential drawback for some consumers.
