Overcomes diesel particulate filter (dpf) issues with diesel engines
Suggested by my car repair garage to save expensive bills cleaning and replacing of the diesel particulate filter for my Nissan diesel engine. Change in driving habits since retiring have led to majority of driving being short distances around town; not ideal for a diesel engine as it never warms up fully. It was recommended to use a small 250 ml tube with a full tank of diesel fuel and then repeat every other tank full. By purchasing the larger bottle, I managed to make significant savings compared to the repair costs, End result has been no issues at all for the last 3 months.

Ich habe die Lucas Oil 40003 Oberer Zylinder Kraftstoffbehandlung ausprobiert, um die Leistung meines Motors zu optimieren. Leider konnte ich keine signifikante Verbesserung feststellen. Es ist möglich, dass mein Motor bereits gut gewartet war und daher keine zusätzliche Behandlung benötigte.
