dekui uz atsakymus. Pasidomesiu del standartu, as paziurejau del raidziu tai:

"C3 Stable, stay-in-grade oil intended for use as catalyst compatible oil in vehicles with DPF and TWC in high performance car and light van diesel and gasoline engines, with a minimum HTHS viscosity of 3.5mPa.s. These oils will increase the DPF and TWC life. "

"A3/B3 Stable, stay-in-grade oil intended for use in high performance gasoline engines and car & light van diesel engines and/or for extended drain intervals where specified by the engine manufacturer, and/or for year-round use of low viscosity oils, and/or for severe operating conditions as defined by the engine manufacturer."

"A3/B4 Stable, stay-in-grade oil intended for use in high performance gasoline and direct injection diesel engines, but also suitable for applications described under A3/B3. "

Tai galvoju jokio skirtumo turbut (turbo dyzeliukui) jeigu pvz pirkti toliau Castrol 5W40 C3 arba Castrol 5W40 B4? Sorry jeigu tai durni klausima, bet tiesiog idomu ar yra skirtumas praktikoje (ar galima pilt 5W40 B4 ant 5W40 C3 virsaus).
