Has anyone tried Lucas UCL fuel additive? Ive been using FP60 for the last two years on every fill up (3oz per fill up) for the benefits of lubercating the fuel pump, injectors and upper cylinders. Its never really increased gas milage but a gallon jug goes along way. Ive been doing some searching on bob is the oil guy and people seem to give high remarks about this stuff.

 

I use it as well as all lucas products

I dont care about the oil additive just the fuel additive. Thanks anyway.

 

used it on 2 tanks now and my gas mileage has been significantly increase. Its added at least 2 mpg's so far. We'll see if it continues.

 

i have used it for years and have noticed what Tdubbs has, better gas mileage, and on most vehicles a smoother idle. it really made a significant difference in my wife suburban with the 5.7, and in my truck with the 8.1 liter. i haven't had my 4runner long enough to say. definitely buy it by the gallon, and i've gotten the best prices at some truck stops and not part stores

 

i use fuel and oil add. on all my rigs i love it. my dad has a 99 tahoe with 260,000 miles and he has always used lucas and synthetic so to me it made that chevy last like a toyota good stuff.
