The UK automotive engine oils market, while exhibiting a relatively modest Compound Annual Growth Rate (CAGR) of 1.99% from 2019-2033, presents a robust and evolving landscape. The market's value in 2025 is estimated at £X million (assuming a logical extrapolation from the global market size and the UK's automotive sector significance), projecting to £Y million by 2033. This growth is propelled by several key factors. Firstly, the increasing number of vehicles on UK roads, coupled with the rising demand for higher-performance vehicles requiring specialized engine oils, fuels market expansion. Secondly, stricter emission regulations are driving the adoption of advanced engine oil formulations designed to enhance fuel efficiency and reduce harmful emissions. This includes a growing demand for synthetic oils and those meeting stringent industry standards like ACEA and API specifications. Furthermore, the increasing awareness amongst consumers regarding the importance of regular oil changes for engine longevity contributes to market growth. However, the market also faces challenges. Fluctuations in crude oil prices directly impact the cost of production and, consequently, the price of engine oils, potentially affecting consumer purchasing patterns. Additionally, the competitive landscape, dominated by global giants like BP, Shell, and ExxonMobil, along with specialized players like Liqui Moly and Motul, introduces intense price competition. Despite these restraints, the market's inherent link to the vital automotive sector, coupled with ongoing technological advancements in engine oil formulations, indicates sustained albeit moderate growth throughout the forecast period. Market segmentation by vehicle type (passenger vehicles, commercial vehicles, motorcycles) and product grade (e.g., conventional, semi-synthetic, synthetic) further reveals nuanced growth patterns depending on vehicle ownership trends and technological advancements in engine manufacturing. Specifically, the passenger vehicle segment is expected to dominate, driven by the large passenger car population in the UK and the rising adoption of new vehicles requiring specific oil formulations. This report provides a comprehensive analysis of the UK Automotive Engine Oils Market, covering the period from 2019 to 2033. It delves into market size, growth drivers, challenges, and emerging trends, offering valuable insights for businesses operating within this dynamic sector. The report utilizes data from the historical period (2019-2024), the base year (2025), and the estimated year (2025) to project the market's future trajectory (forecast period: 2025-2033).

Steam distillation is an important mechanism which reduces residual oil saturation during steam injection. It may be the main recovery mechanism in steamflooding of light oil reservoirs. As light components are distilled the residual (initial) oil, the residuum becomes heavier. Mixing the distilled components with the initial oil results in a lighter produced oil. A general method has been developed to compute steam distillation yield and to quantify oil quality changes during steam injection. The quantitative results are specific because the California crude data bank was used. But general principles were followed and calculations were based on information extracted from the DOE crude oil assay data bank. It was found that steam distillation data from the literature can be correlated with the steam distillation yield obtained from the DOE crude oil assays. The common basis for comparison was the equivalent normal boiling point. Blending of distilled components with the initial oil results in API gravity changes similar to those observed in several laboratory and field operations.

Investigation of Oil Recovery Improvement by Coupling an Interfacial Tension Agent and a Mobility Control Agent in Light Oil Reservoirs will study two major areas concerning co-injecting an interfacial tension reduction agent(s) and a mobility control agent. The first area defines the interactions of alkaline agent, surfactants, and polymers on a fluid-fluid and a fluid-rock basis. The second area concerns the economic improvement of the combined technology. This report examines the interactions of different alkaline agents, surfactants, and polymer combinations on a fluid-fluid basis. Alkali and surfactant combine to reduce the interfacial tension between a low acid number, 42 API gravity crude oil and the aqueous solution to values lower than either agent alone. Surfactant structure can vary from linear chain sulfonates to alkyl aryl sulfonates to produce low interfacial tension values when combined with alkali. However as a class, the alkyl aryl sulfonates were the most effective surfactants. Surfactant olefInic character appears to be critical in developing low interfacial tensions. For the 42 API gravity crude oil, surfactants with molecular weights ranging from 370 to 450 amu are more effective in lowering interfacial tension. Ultra low interfacial tensions were achieved with all of the alkaline agents evaluated when combined with appropriate surfactants. Different interfacial tension reduction characteristics with the various alkali types indicates alkali interacts synergistically with the surfactants to develop interfacial tension reduction. The solution pH is not a determining factor in lowering interfacial tension. Surfactant is the dominate agent for interfacial tension reduction. Increasing the temperature up to 170?F did not significantly alter the interfacial tension reducing capability of an alkaline-branched alkyl aryl sulfonate solution but changed interfacial tension for linear alkyl aryl sulfonates. Shifts in the alkali concentration and/or the range of alkali concentrations which produce the ultra low interfacial tension values were observed consistent with the change in surfactant solubility. The alkyl surfactants which did not produce low interfacial tension at 72?F were still not effective as the temperature increased. Increasing the salinity of the surfactant and alkaline plus surfactant solutions demonstrates that the interfacial tension reduction synergism is not the result of changing salinity for the range tested. Ultra low interfacial tension values for surfactant plus alkali solutions could not be achieved with surfactant plus sodium chloride before alkyl-aryl surfactants precipitated from solution. The alkali plus surfactant solutions with the more water soluble surfactants gave lower interfacial tension values than surfactant plus sodium chloride at the tested salt concentrations. For alkaline plus surfactant solutions which produce ultra low interfacial tensions, an increase of the solution salinity shifted the surfactant which was most effective to a slightly more water soluble type. Also, an increase in temperature increased the salinity at which the minimum interfacial tension occurred for alkyl aryl surfactants. For non-optimum surfactants, increasing the temperature did not change the salinity effects with any consistent trend.
