I have been using all of the Lucas products in my truck for 3 years now, from the fuel treatment, to the diff additive to the new synthetic oil additive. I recommend Lucas to anyone that needs a real additive for their vehicle. I run 35" tires on my truck, and I now have 260,000 kms with no problems. My truck sees lots of offroading and the Lucas line of products makes a noticeable difference.
