Hello together, after my Berlingo (B9) was yesterday in the workshop about a control for a “recall action”, the car dealership pointed out that I should definitely use the recommended engine oil according to the maintenance plan. Which was not mentioned at first. I told him that I used the Castrol Magnatec Stop-Start 0W-30 C2 (PSA B71 2312) which corresponds to an authorized engine oil. But according to his statement Castrol would be a bad oil and I should absolutely Use the TOTAL QUARTZ INEO FIRST 0W30 suitable for ACEA C1 PSA B71 2312. In the maintenance plan is only 0W30 B71 2312 (C1C2) and Citroen prefers Total. Therefore, nothing against the Castrol oil or? Thanks!
