I embarked on a trip after filling my tank up at a major filling station with presence everywhere in the country. I discovered that I couldn't exceed a maximum speed of 120km/hr and the rate at which the car burnt fuel was absurd. As soon as I got back to town I took the car to an auto garage where a comprehensive check was made and they recommend that I change my fuel pump and service the injector system.
I embarked on another trip a few days after and experienced the same thing on my way, but when I was returning I had to refill my tank, which was almost empty and as soon as I embarked on this trip I was able to get to about 160km/hr(bad road couldn't make me do more ) without hitch and fuel consumption was quite reasonable. I learnt from credible sources that there is an additive that is being used to mix fuel by unscrupulous elements and they sell to unsuspecting citizens. Nowadays petrol and water have almost the same color..back in those days no be so!!!
