Hi,
Had to do an emergency top up of the oil in my diesel Touran (103kW/140BHP) engine over the weekend.
Looking at the service book, that engine without a particulate filter will take VW 505, 506 and 507 oil.
With a filter, it requires 507 oil.
I have no idea whether mine has the filter, though I suspect it does being UK.
Long story short - garage only had Castrol Edge Diesel 505.01 compatible and running out of oil is bad (TM) so it got 0.75l of that shoved in.
If the engine really wanted 507 is this enough reason to book a full oil change soon (had one last Sept) or are the differences in 505 and 507 relatively minor, given this was a top up?
Many TIA.
Tim
