Engine oil specs driven by emission legislation: ATIEL

: Oil products
25/11/26

Engine oil specifications have shifted, changing base oil requirements and become more complex because of emissions legislation, delegates heard today at the ACI Lubricants summit in Valencia.

Initially engine oil specifications focused on SO2, NO2 and particle matter emission reduction, but the emphasis has now shifted to CO2 emission reduction, ATIEL president Marco Digioia said.

The shift is the result of changes in emissions legislation and so has had implications on base oil requirements, moving away from Group I. It has also promoted the increased usage of Group II and III base oils in light and heavy duty applications.

But interchange guidelines for the base oil groups have not kept pace with the specification evolution driven by emissions legislation. Current guidelines still focus around Group I base oils, Digioia said.

Funds’ Ice gasoil long position down from 45-month high

London, 4 December (Argus) — Sharp swings in European diesel prices in November were driven in part by entities with no physical exposure, as money managers briefly held their largest long positions in Ice gasoil futures in nearly four years. Funds have looked to gasoil futures because of increasing volatility in the contract when compared with Ice Brent crude futures, according to a senior participant in oil paper markets. The daily change in the value of front-month Ice gasoil has averaged 1.66pc so far this year, compared with 1.32pc for front-month Ice Brent. Money managers — hedge funds and pensions funds, along with other entities managing on behalf of clients — have increased their long positions in Ice gasoil futures as the year has progressed. This reached a 45-month high of 153,689 lots in the week to 18 November, according to Ice's Commitment of Traders report. Ice gasoil futures hit $777.50/t on 18 November, the third-highest of the year. Money managers trimmed 10pc of that position the following week, to 137,971 as of 25 November. Ice futures fell below $700/t on that date, pressured by reported progress on a plan to end the conflict in Ukraine. This led market participants to consider what peace would mean for diesel markets: a slow down in Ukraine's drone campaign against Russian energy infrastructure and, in the longer term, a possible European return to importing Russian diesel. Funds' long position is still almost double the 74,015 held at the start of 2025, and the average 75,398 held in 2024. Long and the short of it Before peace talks started to progress, money managers' net long positions were the highest in more than three-and-a-half years. An analyst said funds have probably taken an overall position of being long diesel cracks — taking long positions in gasoil futures and short ones in Brent. Permanent cuts to refining capacity in Europe, as well as extensive temporary outages this year, have contributed to a disconnect between gasoil and Brent price movements. As gasoil prices rise, refiners can hit capacity limits, which has capped their crude buying and kept Brent steadier. Managed money held the biggest short position in Brent since at least 2015 on 21 October at 190,639 lots. This has fallen since, but did rebound to 163,975 on 25 November, the eighth shortest since 2015. Funds' involvement in futures has further increased volatility, as they tend to buy and sell futures more quickly than entities with physical exposure. That volatility increases potential losses as well as potential gains. Some funds may have made very large losses this year because of unexpected swings, the paper market participant said. European diesel often prices on a exchange-of-futures-for-physical (EFP) basis, using Ice gasoil futures, meaning the futures price can be an influence on the physical price. European physical diesel cargoes priced at a $45.64/bl premium against North Sea Dated on 19 November, the highest in nearly three years. The following week, when money managers were cutting their long positions, the physical diesel premium fell to $27.15/bl. Ice gasoil futures is a physically-delivered contract, so any price dislocation is generally soon closed as traders look to work an arbitrage between the futures and physical.

Qatar presents 2040 climate target to UN

Qatar presents 2040 climate target to UN

Edinburgh, 4 December (Argus) — Qatar has pledged to reduce its emissions by 42mn t of CO2 equivalent (CO2e) by 2040 from a 2019 baseline, with the oil and gas sector "at the forefront of national mitigation efforts". Qatar does not provide its total greenhouse emissions for 2019, but said its climate plan encompasses CO2, methane and nitrous oxide gases. It covers the energy sector — oil and gas, power and water — construction and industry, transport, waste and agriculture, forestry and other land use. Parties to the Paris Agreement were required to submit climate plans, known as nationally determined contributions (NDCs), for 2035 to the UN climate body UNFCCC this year. Qatar had previously targeted emission reductions of 25pc, or 37mn CO2e, by 2030, compared with a business-as-usual (BAU) scenario. BAU scenarios typically assume emissions based on current policies, leaving room for potential increases. The country's emission cuts in its oil and gas sector will rely on "deploying cleaner fossil fuel technologies, developing engineered sinks to store emissions, diversifying the energy mix, and driving operational excellence across existing facilities and infrastructure", according to its climate plan. Qatar is the world's largest LNG producer, with a production capacity of 77mn t/yr, according to QatarEnergy, and its economy is heavily reliant on hydrocarbon revenues. The country's climate plan highlights the country's vulnerability to response measures to mitigate climate change, resulting from its economy's reliance on hydrocarbons. "Qatar is actively working to reduce the socio-economic effects of global climate action," the plan said, adding that it seeks to balance climate goals with national sustainable development. "Despite many efforts and considering its role as a leading producer and exporter of natural gas, Qatar remains significantly vulnerable to climate response measures," it said. Qatar is part of the Arab Group, a negotiating group in UNFCCC climate talks, which is seeking to focus on cutting emissions from fossil fuels, rather than hydrocarbon production and consumption, through increased adoption of carbon capture technologies. The country said it plays "a pivotal role" in supporting other countries' targets by "reliably supplying them with a cleaner alternative to coal and oil and providing a critical backup for intermittent renewables". Qatar's climate plan sees the secure and affordable supply of lower-carbon energy as well as the deployment of carbon capture and storage (CCS) and the management of emissions of energy production as the focus to pursue sustainable development and climate action. The country considers itself to be among the leaders in CCS with its Ras Laffan project, and aims to capture 11mn t/yr of CO2 by 2035. Engineering firm Samsung C&T was recently awarded a contract to build a 4.1mn t/yr CO2 facility to process and store emissions from Qatar's LNG liquefaction plants. Qatar, in its climate plan, highlighted the country's water supply vulnerability to temperature increases and heat. The power and water sector accounts for a large share of the country's emissions. Water scarcity is also responsible for increasing greenhouse gas emissions (GHG) in Bahrain through desalination, although its energy sector remains the main source of emissions, according to the country's new climate plan. The country is heavily reliant on fossil fuels for its energy and revenues, while "limited land availability and competing land-use demands constrain large-scale deployment" for the development of solar energy. Rising demand over the peak summer months this year meant that Bahrain had to import LNG for the first time since commissioning its 800mn ft³/d onshore LNG receiving and regasification terminal in 2020. But it is looking at renewables options and is in talks with Saudi Arabia for a link to a large-scale solar facility. Bahrain said that response measures to climate change "may lead to economic losses that, in turn, hinder Bahrain's ability to pursue effective climate action and achieve broader sustainable development objectives."

Idemitsu, Kanematsu start biofuel supply for ships

Osaka, 3 December (Argus) — Japanese refiner Idemitsu and trading house Kanematsu have started supplying biofuel mixed with fatty acid methyl ester (Fame) for oceangoing ships, to help reduce greenhouse gas (GHG) emissions in the maritime sector, the companies said today. In October, Idemitsu began bunkering cleaner fuel oil, which includes up to 24pc of Fame, for oceangoing ships, using Kanematsu' storage and shipping facilities in southern Japan's Kokura, a spokesperson at Idemitsu told Argus on 3 December. Under this partnership, Kanematsu procures Fame and blends it with fuel oil supplied by Idemitsu. The Fame mixture will cut GHG emissions by around 20pccompared with conventional fuel, Kanematsu said. Idemitsu aims to deliver a total of 5,000t of bio-blended fuel by March 2026, including supply for domestic vessels. This is equivalent to the amount of fuel consumed by a 300,000 dwt vessel during about 50 days of operation, the company added. The start of their commercial operations comes after Idemitsu's demonstration in northern Hokkaido , where it tested bunkering operations for coastal vessels with fuel containing 24pc Fame in 2023-24. Idemitsu is also gearing up to develop a supply chain for low-carbon methanol for vessels, aiming to start methanol bunkering from the April 2026-March 2027 fiscal year.

India's transport fuel demand rises in November

Mumbai, 3 December (Argus) — India's transport fuel demand rose to 3.37mn b/d in November, up by 10pc on the month and 4pc on the year on the back of rising domestic demand, preliminary oil ministry data show. Diesel demand rose by 16pc on the month and 5pc on the year to 2.12mn b/d in November. But gasoline demand fell marginally on the month after festive demand in October. Demand for jet fuel rose by 5pc on the month as air travel activity remained strong. India's diesel demand continues to rise because of rising construction activity during winter. Diesel demand weakens around monsoons as heavy rains impede movement of commercial trucks and vehicles — major consumers of the fuel. Irrigation activities also slowed because of the rain as some parts of north India experienced heavy floods. India's transport fuel demand totalled 3.07mn b/d over January-November, up by 4pc on the year. Gasoline demand posted the largest increase of 6pc compared with a year earlier, followed by diesel and jet fuel each rising by 3pc. India exported 1.29mn b/d of oil products in November, up by 12pc on the year, according to market intelligence firm Kpler. Crude imports also rose by 15pc on the year to 5.07mn b/d in November.

September US base oil production falls 8pc: Correction

Corrects paraffinic base oil output and base oil products supplied in story published 1 December. Houston, 2 December (Argus) — US base oil output declined 8pc in September from year-earlier levels to 156,700 b/d, according to the Energy Information Administration (EIA) data, driven by a fire at a Louisiana blending facility. Smitty's Supply experienced a fire at its Roseland, Louisiana, blending facility in late-August that limited a portion of base oil offtake. The fire decreased September base oil production by 12pc from August levels. Many US refiners were building inventories ahead of Excel Paralubes' 22,200 b/d refinery turnaround in Westlake, Louisiana, to offset potential limited availability. Other producers had sufficient hurricane inventories to rely on. September paraffinic base oil output was 144,830 b/d, down by 0.2pc year over year and down by 5.7pc from August levels of 153,550 b/d. Base oil products supplied, a proxy for domestic demand, rose 29pc from a year earlier and 5.6pc from August levels, according to EIA data. Demand was elevated for September because Ergon's 25,000 Group I/II refinery in Vicksburg, Mississippi was down for its planned turnaround and Excel Paralubes was preparing for its early October maintenance. US base oil production declined in the Gulf coast, Texas Gulf coast and midcontinent regions because of several refiners were limiting spot offers in order to keep inventory levels balanced during turnarounds. Naphthenic base oil output fell by 53pc year over year to 11,480 b/d, and by 54pc from August levels of 24,970 b/d. Naphthenic levels dropped mainly because Ergon's naphthenic unit was also down for turnaround in September, which kept supplies limited despite firm demand for most naphthenic grades. September EIA export data was estimated using August totals because recent Census trade data is unavailable following the partial US government shutdown. Monthly export numbers are unchanged because of the lack of new data.
