“For two years I have been running a GT Limousine with a 351 Cleveland engine on super without problems. On running the vehicle for a very short period of time with LRP (Lead Replacement Petrol), I was appalled that the engine wouldn’t start, regardless of whether the engine was hot or cold, and started pinging, surging and missing under acceleration. On top of this, I started experiencing major loss of power. I also found it ran hot whilst idling in slow traffic.
I changed to fuelling with regular unleaded and started adding a dosage of Red Line Lead Substitute with Red Line’s SI-1 Complete Fuel System Cleaner (SI-1 - to clean the carbon residue from LRP out of the system). The change in the engine running was immediate and dramatic. No longer did the engine splutter and our fuel economy improved which was an unexpected side benefit.
We know that others were having similar problems running the LRP and had since solved the problem by using Red Line Lead Substitute. I now run your Lead Substitute in the GT at all times. Since my recommending your products to my work associates, they have also used and experienced similar results from using your product.”

“Thanks Red Line - I just saved the $586 I was quoted to get my injectors serviced. My car definitely had an injector blockage problem because when I pulled up or took off from stop lights the car hesitated and missed. After using Red Line's Fuel System and Injector cleaner SI-1, within half a tankful my car had completely been restored of its lost power and now runs smoothly. I now add a bottle every service interval or about every 10,000kms to keep the system at its peak.”
