Is there a “best time” to pour some fuel additive into the tank? There aren’t any instructions on this LUCAS bottle. I checked some other brands and they say to add it to an empty tank immediately before you fill it up.
Does it matter or what? I think the empty tank is a good idea because the new fuel will agitate and therefore mix more consistently with the additive.
I have always added it while filling up so there’s not a big concentration on the bottom of the tank and the action of addingfuel should mix it up good. I think as long as you add it to an eventual full tank of gas all is bueno
and I use RXP about once every 5-6 tanks- I’ve never heard of LUCAS additive maybe i just dont remember. Is there a link anywhere to a fuel additive comparison?? Which one’s the best?
well, i sued the lucas additive and now my car is stumbling like crazy and will not run. it will idle fine for a bit but once i step on the gas, it stumbles and will not go above 1500 rpm. i added it with more than 3/4 tank of gas. the thing said to pour the entire bottle into the tank.
after pouring it in, it drove fine for about 2 miles then started stalling on the freeway. i wonder if the lucas treatment did it… i’m still trying to figure it out
