I have a mint condition GMC Envoy SLT 4×4 with 157,500 miles on the clock. I bought the vehicle in ‘09 with 35k original miles on it. From the start I’ve been using your Fuel Treatment, Heavy Duty Oil Stabilizer, Automatic Transmission Fluid Conditioner, and Complete Engine Treatment. At 100k I switched over to synthetic oil and use your Pure Synthetic Oil Stabilizer along with several cans of your Complete Engine Treatment on top of the oil. My truck runs flawlessly and takes on the most severe Jersey winters with no issues whatsoever! I attribute that to my faithful use of your products! Your products keep my truck young and full of power! Without a doubt….you have a satisfied customer for life!

I drive a ’04 Trailblazer 4.2 with 175,000 miles. I change oil religiously with 6 qts Mobil 1 full synthetic and a qt of full synthetic additive (Lucas Pure Synthetic Oil Stabilizer). The ticking noise drastically reduced and runs great. I use many Lucas products from trans to power steering to Complete Fuel Treatment. I don’t use anything else. Love your products.
