13 car brands, 5 motorcycle brands and 7 oil marketers back E20 (gasohol with 20% ethanol). The Department of Business Energy says about 4 million cars and roughly 80% of motorcycles can use E20, but E20 sales average only 5.88 million litres a day, about 18% of benzine use. Officials say Thailand has 28 ethanol plants producing about 7 million litres a day, with room for 3-4 million more. Oil dealers plan discount and promotion campaigns for E20 buyers. Check whether your vehicles are on the government list. If you run a fleet or deliver fuel, E20 promotions and pricing may shift which fuel your drivers buy. The article gives no E20 price or the promotion dates.
