Stats are based on Texaco Chevron’s research:* Based on savings made by a limited but we believe representative sample of Petrol and Diesel cars tested. Figures calculated in accordance with:(a) independent testing June-September 2012 across four different popular models of petrol car and six popular models of diesel car over a 500 mile test cycle. Figures from these tests were: average Petrol MPG pre Techron 26.6 , average Diesel MPG pre Techron 40.7, average post Techron Petrol MPG improvement 8.7%, average post Techron Diesel MPG improvement 7.6%;(b) cost of petrol at £1.148 per litre and diesel at £1.119 based on AA fuel report August 2015;(c) fuel saving figure includes the cost of Techron treatment (recommended every 6 months or 6,000 miles) at £19.99 each (savings figures will vary dependent on purchase price);(d) savings based on average annual mileage of 6,900 miles p.a. for Petrol cars and 11,200 miles p.a. for Diesel cars in accordance with Department for Transport statistics: Annual mileage of 4-wheeled cars by fuel type: Great Britain, 2002 to 2012; and(e) testing data based on vehicles with PFI Petrol engines or Direct Injection Diesel engines.
