Phil Howard uses Lucas Stabilizer and has over 400,000 miles on his pickup truck.
First I will say that I have never wrote to any manufacturer of a product in all my 47 years on this planet. My truck at about 270,000 miles suddenly dropped oil pressure to 5 psi when I would pull up to a stop light and leave it in gear. I put a new mechanical gauge in it to make sure it was correct and it was. I went to the store and bought an oil change kit plus a quart of lucas stabilizer. Within a couple of minutes the oil pressure came back up and has stayed up to present day. I now have just over 400,000 miles on it and it still holds 50 psi while driving and 25 psi in gear at a stop sign. I drive this truck everyday.
One more thing, The overdrive in my same truck started shuttering real bad over 100,000 miles ago so I added a quart of the lucas transmission treatment. Been using it ever since. That transmission also has over 400,000 miles on it. I now use Lucas oil stabilizer in both my daughters cars, tractors, all 4 atv's and even my lawn mower. By far the best product I have ever used. Keep up the good work!
