My personal experience using Tufoil, i used it in my 1986 RX-7 FC3S, was damn scared to use lar, scared engine jam or what, 1st time put one bottle inside, then first few days cannot feel a thing, after 1 week suddenly i was wondering to myself ' why my petrol cannot finish 1 r?'. then i started to track the mileage lar, without tufoil last time i get 350km full tank, after that i was able to get 400-450km. was damn suprised with the result. i check my oil temp and water temp, both running cooler and somemore last time my car when running for long periods of time, sure very hard to start, after i use tufoil, i noticed that it doesnt happen anymore. smooth start all the way
now sell car edi :(
i just put one bottle of tufoil today in my mazda 6, but i'm sure got improvement one
in my opinion, tufoil has not let me down lar :shades_smile:
