Driving from the Alabama - Tennessee line to the gulf coast, most downhill I mind you - predominantly interstate, I have never gotten more than 23. This was with little to no load, Nitrogen tires, Fresh air filter & oil, premium fuel, & Lucas fuel tx additive.
I try to use Lucas every few fillups. Always have and I’m setting on 160k.
When I was having really bad fuel consumption on my Corolla I put some of the Lucas with a full tank of gas and worked like a champ
Lots of naysayers regarding this. However I started using Lucas in my 1995 tacoma and it got rid of a rough idle, got. better gas mileage, and even got rid of p0300’s codes.
My Toyota suddenly had the check engine light (money light) come on. It was the dreaded P0240 error code, indicative of a bad catalytic converter. I added a bottle of Lucas additive to a full tank and the light went out.
Put a bottle in my 5.3 yesterday and the slight misfire went away. Done that for a few years now
Lucas. I can't prove it works with data... But I've felt the difference. I swear by the stuff.
I haven't used the oil treatment yet, but I was amazed at how well the fuel additive worked. I noticed an immediate increase in fuel efficiency (in two different cars).
