Oil D5 Euro 4 (no DPF)
Hi,
I'm new here and witnessed a lot of diesel knowledge on this forum. In the near future an oil change is due for my 07 S60 D5 and wanted to see if I can use a 'better' oil than specified by Volvo for this engine. The a5/b5 spec is specifically for long intervals, fuel consumption and low emissions. I don't believe it provides the best protection even when Volvo says so. Now the fun part about this question. My car now has around 140k miles (223k km). Originally it came with a DPF, but mine is tuned and the DPF is no longer working/existend. So an a5/b5 oil is no longer needed for this purpose. I also never wait longer than 10k mils (15k km) to change the oil. As far as I know and understand a low SAPS oil isn't neccessary anymore. My last car, Alfa Romeo GT JTD 2005 (euro 3), ran on Valvoline Synpower 5w40. well over 220k miles (350k km). Never had any engine issue or oil consumption etc. I think I can use this oil, but can I? I realize this is another oil question. But could not find the answer. Are there any owners here that have their car setup like mine or any that can give a substantiated response to my question? (I'm from NL, so if my English is a bit wrong... I apologize) |

The only improvement you can make is switching to A3/B4 as it warrants a higher hths value. Other than that they are largely the same, and offer the best protection in terms of being high saps. C spec oils would be a backward step. A5/B5 is high saps not normally used with dpf's, C spec are the mid or low saps 'dpf' oils.
Have a read through this thread, it might help. The references to the euro 3 oils are of use if you wish to deviate from A5/B5. https://www.volvoforums.org.uk/showthread.php?t=283503 Last edited by AndyV7o; May 10th, 2019 at 14:29. |

so you would not advice a A3/B4 5W40 type oil on an engine with 220K+KM on it, or would you say that's just fine?
I always thought that you can switch to a higher weight oil within the same oil spec. But my car doesn't 'need' A5/B5 anymore. I got rid of the DPF and I'm not going to do 30K km oil changes. I'll change every 15K km. a Full Syn 5w40 A3/B4 oil would do than, right? |

Diffcult.
Depends on whether volvo did or didnt tighten up the engine when revising for euro 4, but then there are other things involved too. Basically it should be ok yeah, but I'd advise only shell helx ultra 5w40 since it is a thinner oil, if there were intermediate numbers it would be a 2.5w35. Thing is, the viscosities have a range, most 5w40 are at the thicker end of both 5 and 40, whereas a 0w30 resides at the thinner end of 0 and 30, thus the change to 5w40 is pretty big. The only exception I am aware of is s.h.ultra which is at the thin end of the 5 and 40 range. Tbh a 0w40 such as Fuchs titan longlife 0w40 ir Mobil fs 0w40 would be a more appropriate transition. See the table ill attach to get an idea where Im coming from. The castrol is the std benchmark oil, now this is A3/B4 0w30 (no longer available) but the viscosity of the A5/B5 is about the same, just the hths is lower, so still representative of your original fill. The fuchs and motul 5w40 are typical of pretty much all 5w40 viscosity wise. |
