Tomas Mansfield uses Lucas Fuel Treatment in 1988 Ford F150

Dear Lucas Oil,

I am a faithful user of your fuel treatments. I use a small bottle of it about third or fourth fill-up in my 1988 Ford F150. My truck has 151,000 miles on it, but when I add your fuel treatment, it drives like new! The effects last for a few fill-ups, and with the occasional follow-up octane booster, my "baby" never suffers from lack of power.

I am looking at possibly using your octane booster for off-road applications, and I am already recommending your products to my friends and family!

Thank you for a reliable American product!
