Suitability for my Vauxhall Zafira Design CDTI (120)
I have an engine management light on my dash and the diagnostics advise that this relates to the EGR valve.
I have been advised that it may be the case that the valve may be clogged and an additive/cleaner may help resolve this problem.
Is this product suitable for use in this situation and is there a limit as to how much additive can be used in a car over a period of time?
Will this clean the EGR valve?
I have the same car and have just started adding this to my fuel. I can't advise on the valve issue but on performance and economy I would give it a try. Combined with Jet fuel, (that is fuel from a Jet filling station, not an aircraft before someone asks) it gives much more low down torque and mpg seems better.
