Normally, I go for the cheapest supermarket, usually Morrisons, near us. For the 1st time today, I actually read theISO label. It's says they (Morrisons) use/blend 7% bio diesel. As the nearby BP is only 1p/litre dearer, I'll use them in future, as the difference will only beapprox 50p/tankful.
Just to clarify with regard to biodiesel fuel in the Mokka.
Page 141 of the user manual states that diesel fuel must comply with EN590.
EN590 allows the blending of up to 7% fatty acid methyl ester biodiesel with 'conventional' diesel.
Hence the Mokka is OK with regard to 7% biodiesel.
