Lucas Oil Octane Booster, 444-mL

Made my motor knock and ping will Never use again

All lucuas produce are great in my opinion.

I have been adding one bottle to a full tank on my truck. (2010 F-150 with the 5.4L Triton V-8, automatic transmission and 4X4 with the trailer package.) I don’t go below 1/4 tank, and I was already running 94 octane from my local Chevron, and a K&N filter in the factory housing. With the octane booster I’m at a total of approximately 97 octane. (The first tank took two bottles, because it’s a 130 litre tank.) With just the octane booster added I have picked up just a shade under 200 kms per tank, and the truck seems to be burning much cleaner. I have not hooked it up to a test machine. So I can’t give any scientific numbers. But my exhaust as lost almost all of the black inside the end. Now you can see mostly the rust and only a slight hint of black. Where as before the octane booster the inside was still fairly black. Not heavy black like it was on regular gas with a factory Ford paper filter. Replaced as required, by Ford. But still black. I have made the listed changes 1 at a time so I can see exactly what it does. I also run a bottle of Lucas fuel system cleaner and every oil change to keep the fuel system as clean as possible to keep it running as efficiently as possible. Fuel expensive, and I want to get as much as possible from every drop. Plus open it up once a week on the highway to clear out any carbon as one should. But otherwise I drive for fuel economy. The air filter added 40 kms per tank and freed up a noticeable amount of bottom end power. The 94 octane added I don’t remember the exact number. But around 100 kms per tank, and the truck ran a little smoother and a slight bit more power all the way through the rpm range. But mostly noticeable at the higher rpm’s. These changes are enough to offset the cost difference, and then some. I know some people will say Octane doesn’t affect fuel mileage, or power. All I can say is these are my results. Try it yourself if you don’t believe me. The truck is low mileage especially for the age. 176,000. It’s mostly used the family car. So it has the taller gears. Not much towing, hauling, or hard driving. The most off roading it has done is a muddy driveway to my friends ranch. So it has led a fairly easy life. Maintenance done religiously. I would recommend if you have the same or similar truck to give these changes a try. Go at least 3 tanks to see the full difference, and run the Lucas deep clean fuel system cleaner first. Just to make sure you are starting with the fuel system as clean as possible to be sure your running as efficiently as possible to start. Side note: I live in a hilly mountainous area. So that may also affect the numbers I’m getting. Versus what some in a flat area would.

If you run cheap gas that has a high content of ethanol you are going to want to boost that out as much as possible. Lucas has alway provided our shop with the best possible products. Highly recommend.

Seemed to work well as described.
