Goodbye Acea C1, Acea C1 Specification has ceased to exist.
Hi guys, I have a doubt.
Since 2021 the Acea C1 specification has ceased and subsequently from 2025 manufacturers will no longer supply lubricants with this indication.
Which specification will be able to fully satisfy the FORD WSS-M2C934-B/JAGUAR STJLR.03.5005 approvals which are those recommended by the parent company? The specifications that will continue to live are those relating to the C2 up to the C6 but they all seem to me not to simultaneously satisfy all the characteristics of the required approvals (low viscosity, low emissions, low ash content and HTHS index) .
Even if it is true that we still have time to be able to worry (always hoping to wish a long life to our loved ones), why don't we start to think clearly and find out, possibly with LR or with experts, about which lubricants to use?
What do you think about this?
A summary of the specifications:

C1 = Low viscosity lubricants with the lowest SAPS content (Low SAPS). Specification disused since 2021, but which ACEA continues to report on lubricants with these characteristics until 2025 with the C1-2016 specification (date of the last update). It will be absorbed by the following C specifications, based on the physical characteristics of each individual lubricant that currently contains it. Used mainly by Mazda, Jaguar, Land Rover and Ford
C2 = Lubricants with medium SAPS content (Mid SAPS), intended for the use of prolonged oil changes in engines that require low viscosity and an HTHS value between 2.9 and 3.5 mPa. Mainly used on FIAT and PSA group cars
C3 = Mid SAPS lubricants which differ from C2 lubricants by a higher HTHS value, which in these lubricants is a minimum of 3.5 mPa. Recommended especially by the main German OEMs such as BMW, Mercedes Benz, Opel and VW group (VAG)
C4 = Lubricants with the same HTHS value as ACEA C3, but with low SAPS content. Used by Renault group cars and Nissan diesel engines
C5 = Evolution of low viscosity lubricants which differ from those with ACEA C2 due to an even lower HTHS value (minimum 2.60 mPa). They are used on the latest generation Euro 6 engines of the main European OEMs, such as BMW, MB, Vovo and Fiat, VW and PSA groups.
C6 = Compared to C5, they guarantee excellent protection in petrol engines during pre-ignition at low speeds and against wear caused by deposits in the turbocharger of diesel engines. Latest generation specification coming soon.
