hello my friends! My girlfriend has an volvo d3 2014 D3 with DPF that calls for a thin a5/b5 oil with high ash/saps.. Are there any risks with running a c3 oil instead? I have been running one service interval (30000km/18500miles) on ESP 5w30 C3 (low saps) before with no problem, now im on 5w30 A5/b5 again and on shorter service intervals (15000km / 9000miles). We have more cars and a C3 oil would be nice to run in the volvo cuz then I can have the same oil in more cars.
Why is volvo running high saps oils with DPF when almost every other car-manufacturer strictly use C3/low saps oils? I dont think volvo is over-represented in DPF/EGR problems ither..
does anyone here run their volvo 5cyl diesels with dpf on 5w30 C3 oils? or even 5w40 c3?
best regards!

Dpfs were around before the low saps oils came along, they all ran full saps back then. IMO low-saps was a solution in search of a problem...

A5/B5 is not a low ash/SAP oil. That would be A3/B4. C3 is a mid SAP oil.
Your choice but with DPF I would stay with a low SAP oil.

I fully agree on ka9mnx. C3 is actually rather as existing as DPFs in passenger cars.
C3 isn't any issue at all and far from being 'a solution in search of a problem'.
I'd just run that Volvo Diesel with a proper C3 like M1 ESP 5W-30. It's excellent.

Volvo fitted enormous DPFs and specified A5/B5, bucking the trend of the time for smaller DPFs and C3. They have since launched their own mid-SAPS spec for the newer VEA/'Drive-E' engine range.

SAPS is approximately the same for A3/B4 as for A5/B5, the main difference is the HTHS. A5/B5 does also have a tougher limit on biodiesel-induced oxidation resistance.
