Laurence Mardon uses Lucas Fuel Treatment in Mazda RX-7 -- 1st generation w 2nd gen. turbo swap

I run a beautiful first generation Mazda RX-7 with a 2nd generation turbo engine swapped in. The first gen RX-7 (and the third) was a pure driver's car: great handling and -- with the turbo -- very nice performance.

I've made a number of modifications and tried different doo-dads, but I'm just writing to say that one of the most effective is your Upper Cylinder Lubricant with Injector Cleaners.

I've used it for the last 5 or 6 fill-ups and I'm very impressed: my engine is running much smoother, with a beautiful note to it when I pull away from the traffic behind me.

Great work, Lucas, whoever you are!
