hello,hmmm this is the very quandary I have rite now,or at the turn of the year…I have a 70 plate Tiguan elegance 1.5tsi and it’s a lovely car,good to drive,but with this E10 I noticed a reduced mpg it’s around 34mpg,I find this poor,it used to be up round the 40 mark…what to get next???the diesel would improve this but it more expensive and decent hybrids and electric SUV’s are very costly
