Well i went over to my mates garage and as i pulled up had this elderly man questioning me about my starlet, he was mentioning a fuel cat basically a catalyist what is put in the fuel tank and takes normal 95 octane petrol upto just over 100 octane fuel !! Now i thought as he mentioned it was pure bulls**t but as he kept me there for nearly an hour talking about it i began to come round to it , if he was lieing then this bloke could lie for england any one else ever heard of it ? tempted to try it as he said he offers a 5000 mile guarantee and if your not happy with in that he will let you bring it back ! better fuel economy burns the fuel at a much lower temp less emisions and high octane fuel on tap last for 10 years??
