Whether I’m chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me

My name is Jim Klinkner the owner of Klinks Premium Wildlife Blend. I'm a firm believer in Lucas Products. I use Lucas Synthetic Outboard Marine Oil in my Bass Boat and I use Lucas oil in my ATV's. I depend on Lucas Products whether I'm chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me. My machines seem to love Lucas Products better than the rest. Less plug fouls, less smoke the machines running better and smoother. Thanks Lucas

I am amazed at what it has done to my engine noise.

I own a 2008 Ford F`50 with a 5.4 engine and 137,000 miles. Over the past year my engine developed the Ford death rattle. It's known as cam phaser problems. This was when pulling a trailer at low idle. I decided to try out Lucas High Mileage Oil Stabilizer additive.T his was 12,000 miles ago, and I am amazed at what it has done to my engine noise. It's been gone since a week after I started using it. I told my son in law about it, as his Honda engine is using oil and fouling plugs. He is amazed at how it has helped his engine trouble and he has not fouled a plug since he started adding it.
I also have added it to my old Briggs and Stratton 5 hp engine. It smokes really bad, since adding it has cut it down 80 percent. It has made believers out of us. Thanks

We have been using Lucas Oil Products in our kart for four years now and there is simply no better products. We race all over the southeast and people are always coming up and asking what we are using and how it is performing. Thank You Lucas Oil for your support and your awesome oil products.

I’ve been using Lucas Products for my vehicles for many, many years now with complete satisfaction.

I've been using Lucas Products for my vehicles for many, many years now with complete satisfaction. I came upon their gun oil many years back while at my local auto parts place while still living in California. Been using it ever since while all the other products I have collect dust.
