ne gre ravno po vrsti......A3/B3 nudi boljšo zaščito od A1/B1
The full ACEA specs are:
* A1 Fuel Economy Petrol †

Mineral oils:
* E1 Non-turbo charged light duty diesel
* E2 Standard performance level
* E3 High performance extended drain
* E5 (1999) High performance / long drain plus American/API performances. - This is ACEAs first attempt at a global spec.

* E6 Euro 4 specification - low SAPS for vehicles with PDF (see below)
New low SAPS (Sulphated Ash, Phosphorous, Sulphur)
This oil is a recent introduction for diesel engines fitted with a DPF (Diesel particulate filter). This is effectively a filter unit in the exhaust that takes out the microscopic soot particles. If you don't use a proper low SAPS oil, then the additives can block the filter with ash, which is a bit like putting a potato up your exhaust! New filters are pricey - £1500 isn't unusual.
* C1 Low SAPS (0.5% ash) fuel efficient
* C2 Mid SAPS (0.8% ash) fuel efficient, performance
* C3 Mid SAPS (0.8% ash)
Many OEM are now using their own specifications to capture this spec. eg. Mercedes 229.31/51, BMW Longlife 04, VW 507 00 etc.
