Reference library
Manufacturer
Volkswagen engine-oil approvals range from legacy VW 500/501/503/505/506 series to current vehicle-specific VW 502 00, 504 00/507 00, 508 00/509 00, VW 511 00 and regional VW 508 88/509 99 requirements. Always match the exact approval and viscosity specified for the vehicle, engine and market.
Manufacturer
Ford engine-oil, axle-lubricant and transmission-fluid specifications, including legacy WSS-M2C913 oils and newer Ford WSS and MERCON requirements. Ford specifications are application-specific: use the exact viscosity and specification stated in the current owner’s manual or workshop information for the vehicle.
Manufacturer
BMW Longlife specifications are application standards, not a simple progression in which the newest oil replaces every earlier one. Oil must match the vehicle’s engine, model year, emissions equipment and sales market. Viscosity alone is not enough: two oils with the same SAE grade may carry different approvals. Likewise, terms such as “fully synthetic,” an ACEA or API classification, or a particular base-oil group do not replace the required BMW approval. Always confirm the permitted specification in the owner’s manual, BMW Driver’s Guide, under-hood label or a VIN-specific BMW service system. Some BMW M engines require dedicated oils such as 10W-60 that are outside the regular Longlife specification system.
Manufacturer
Current GM engine-oil requirements center on the licensed dexos family: dexos1 Gen 3 for many gasoline applications, dexosR as the newer high-performance gasoline successor path, and dexosD for light-duty diesel applications. This refresh corrects the obsolete blanket Duramax/API CJ-4 statement, identifies dexos2 and earlier GM long-life approvals as superseded, and updates the DEXRON section with VI, HP, ULV and FFL-4 context.
Manufacturer
Fiat/FCA engine-oil requirements are vehicle- and engine-specific qualifications, not universal substitutes for one another. Older FIAT 9.55535 suffixes remain relevant for legacy vehicles, while newer Fiat/Stellantis documentation also uses 9.55535-DM1, DSX, GSY and the harmonised Stellantis FPW 9.55535/xx family.
Manufacturer
Mercedes-Benz passenger-car and van engine-oil specifications are identified by MB sheet or MB-Approval number. The current Mercedes-Benz Operating Fluids system lists approved products for each sheet, while sheet 223.2 and the vehicle’s current owner’s manual determine which approvals and viscosity grades are permitted for a particular engine.
Manufacturer
PSA Peugeot Citroën engine-oil specifications remain relevant for many existing Peugeot, Citroën and DS vehicles, while newer Stellantis FPW9.55535 specifications now appear alongside them. This page distinguishes the main legacy PSA codes, later PSA low-viscosity requirements and current Stellantis-labelled specifications.
Manufacturer
Current Renault engine-oil specifications include RN17, RN17 FE, RN17 RSA and AN2022 alongside the established RN0700, RN0710 and RN0720 requirements. The page also covers manual-transmission-fluids: the new Tranself NFX and some other, legacy products.
Manufacturer
Volvo passenger-car engine-oil specifications span current low-viscosity 0W-20 requirements and several engine-specific legacy specifications. The vehicle’s model year, engine, market, and current owner’s documentation determine the correct oil; a Volvo specification cannot be substituted solely from the SAE viscosity grade or a broadly similar ACEA/API claim.

ACEA Engine Oil Sequences: current light-duty (2023) and heavy-duty (2024 Revision 1) categories, claim-status dates, terminology, and historical context.
Organization
ISO 13738:2011 remains the current ISO specification for two-stroke-cycle gasoline engine oils. It defines the ISO-L-EGB, ISO-L-EGC and ISO-L-EGD categories; ISO 13738:2000 is withdrawn. The page now distinguishes these active ISO categories from their historical JASO relationships and notes the newer JASO M345:2024 revision without presenting JASO and ISO claims as automatically interchangeable.
Organization
JASO engine-oil classifications include active two-stroke JASO M345:2024 grades FB, FC and FD; active four-stroke motorcycle JASO T903:2023 grades MA, MA1, MA2 and MB; and ultra-low-viscosity passenger-car gasoline-oil classifications under JASO M364:2025. JASO markings in the JALOS on-file system are supplier-filed performance claims, not JASO product approvals.

ILSAC gasoline-engine-oil specifications: current GF-7A and GF-7B, the GF-6 transition through September 30, 2026, API certification marks, and historical GF categories.
Topic
Current API engine-oil category charts, updated for API SQ and ILSAC GF-7 while retaining the relevant historical gasoline and diesel categories.
Topic
API Publication 1560, 9th edition (November 2023), now lists API GL-5 as the only API automotive gear-lubricant service designation in current use. GL-1, GL-2, GL-3, GL-4, GL-6, and MT-1 remain important historical designations but are not in current use; API specifically notes that GL-4 test hardware is no longer available for performance verification.
Topic
Historical API two-cycle categories TA, TB, TC and TD are retained for label and manual compatibility, but none should be presented as a current API licensing category. The page now distinguishes legacy API terminology from current ISO, JASO and NMMA two-stroke oil standards.
