Just had my second MOT done at 37000 miles and was pleased it passed with flying colours. Best of all though for me was the exhaust opacity test result of 0.06 which was commented on as being very good.

As a 2SO user for 9 or 10 months my confidence in it as an additive has been reinforced by such a low figure but I'd be interested to know what results other members here are getting using 2SO or not.

My test reduced from 0.9 to 0.5 after using 2SO.  10MY (Sept 09) TD4 HSE Auto in Stornoway Grey (Now Gone)
