Drain Diesel from Petrol help across Hertfordshire
Our technicians are out across Hertfordshire around the clock, covering Welwyn Garden City, Watford and St Albans and everywhere in between.
When diesel goes into a petrol car it sinks, coats the fuel system and leaves deposits on plugs and injectors. A proper drain gets all of it out, so the car starts and idles cleanly, with no lingering misfire.
Breakdowns on the A1(M), A10 and A414 are reached quickly, and we attend lay-bys, services and car parks as well as forecourts.
