Went to a fastfit in Bletchley MK to get rear brakes done on PD170 DPF...at same time they offered a service,  i was due for one so agreed providing they put in correct long life oil in. .never again.   On checking receipts, they've put in triple qx (low saps) c3 oil that looks like VW505.01 spec not 507.00..... Do you think it is okay to run on this  for a week or so...as i have it booked in at a vw specialist to put in proper oil but not til next week...thoughts...cheers.

I would of thought one week would be fine as 505.01 is not a low ash oil so longer term use would cause the DPF to clog up quicker.
