Hi together, I have to fill in oil with the approval 229.5 for petrol engines with my Mercedes M273 (2009) engine. I filled in the approval 229.51 (for DPF) last autumn. The car is actually running well, but does the wrong oil do unnoticed damage? What do you think, can I leave the oil in it until autumn (next maintenance oil change) or should the oil exchange as soon as possible? An autoversed friend prefers to say out yesterday than today, at Mercedes they are relaxed and I’ll make about 3000km until autumn. Thank you.
