I am comparing FP60 and Lucas UCL for MPG increases. It’s not a perfect experiment, but it is some real world data with as little variables as I could achieve under normal circumstances. Vehicle is a 1993 Mazda MX6 2.0L DOHC 5spd, in good tune. EPA rated 26/34. Fuel tank capacity is 15.5 gallons. Treatment rate is 1oz/5gal except for one tank of UCL which is noted at 3oz/10gal rate. If the previous tank did not contain any of the same additive, 3oz was added to get the correct rate. If a previous tank DID contain that additive, it was added at ~2.5oz, as fill-ups were generally around 12gal. Tires were kept at 40psi. 6 tanks were used for the average MPG for FP and UCL, one sole highway mile tank of FP60 was not used (34.75mpg). 9 tanks were used for the average MPG with no additives. You can see that Shell gas was used almost exclusively (5% rebate) and also note that the ounces of additive was also accounted for when calculating MPG.
Now the cost analysis. The average $/gal of gas during this experiment was $2.596. Using $28/gal for UCL with tax comes out to $30.17. Using the cost of FP60, plus shipping, but with no tax and at the old price it comes out to $36.21/gal. When using these products at 1oz/5gal, the cost equates to an increase of 1.82% per 1 gallon of gas for UCL and 2.18% per gal for FP60, or $0.71 and $0.85 per tank, respectively. Using an avg MPG of 31.12, UCL must increase MPG by 0.57 to break even and FP60 by 0.68. UCL increased MPG by 1.10 or 3.53% and FP by 0.61 or 1.95%. FP60 basically pays for itself. Lucas UCL seems to be actually saving me money. I look forward to trying the new FP3000.

In case the picture links go down in the future: the MPG averages for no adds, UCL and FP are 31.12, 32.22, and 31.73.
