Dear Lucas Oil,

I am a 25 year old fisherman who moved to Phoenix, AZ with my fiancé to be closer to our God son.  I grew up in Omaha, Nebraska and went to the University of Nebraska where I started the Husker Bass Anglers, the college fishing team at the university.  The great thing about being involved in the fishing community is the number of great connections, and friends that you make.  This is also true for sponsors.  I attended the weigh in at the Lucas Oil Team Open at Lake Pleasant.  Being that I just moved and was not comfortable with the lake I did not fish it, but I went to the weigh in.  You put on an amazing event, and I heard story after story about what amazing products that Lucas Oil makes.

Well, about 2 weeks ago my fiancés car started making a noise, nothing crazy, but just a small whining at the start of acceleration, and then it would stop.  Last week it became very noticeable and louder and my little mechanical experience told me that her transmission was slipping between 1st and 2nd gear.  I took her 2008 Ford Focus with 65,000 miles to a local shop and explained to them my problem.  They checked it out and told to me that I need a new transmission and that they would get me a quote.  I asked about additives and I was told that the additives would not work in new transmission, but that they were geared toward older basic transmissions.  On the way home, ‘thinking how are we going to afford a new transmission and buy a house’, we are currently looking.  I stopped at Advance Auto Parts and figured that the small amount of money to try an additive was worth it.  I immediately found your product, and bought it because of the great things I have heard and because of your support for my beloved sport.

It is now 1 week later, and her car runs AMAZING.  It shifts smoothly, with no issues, and the Lucas Oil Stop- Slip worked immediately after I added it.  I want to say thank you so much.  My boat, truck, and fiancés car will only run Lucas Oil in them from now on.  Your continued support of fishing and your stance on providing a superior product at great prices is what keeps your business growing.


Thank you for saving me $3,581.14,
