Hi. Id just lyk to know if viable to convert my 07 ford xplorer edie bauer to lpg? It runs at 4km/l city driving thats why it's only used twice a wk: coding of the other car and as sunday car.. How much will it set me back and is it worth it in terms of roi? Tnx in advance.. Also, tried and tested na ba ang auto lpg and di naman mgkkaproblema sa auto, particularly in terms of power or cost of maintenance? Id apreciate your xperiences and feedbacks, Tnx again
