I am happy to announce that I have a 1998 W900L Kenworth studio sleeper with a 3406E-550 cat & have excedded the one million mile mark. Combined with my regular oil which is delo 1540, and have always used since 40,000 miles and added 2 gallons lucas to my oil which service intervals are 10-12,000 miles. I also use it in my eaton transmission & eaton rears which are service two times a year. The transmission & rears also exceed the million mile mark and have never been touched. Oil samples on my engine, transmission & rears according to speed co are always nice & clean & show no sign of wear. I use your fuel additive, & hub oil as you might say I am a Lucas fan. I have been approched at truck shows by other lubricant companies but I am quite happy with Lucas. I have seen ads in landline magazine (as I am an OOIDA member) on your truck & just had to tell you about mine. I hope to get the same kind of mileage as you talk about on yours.

Thank you for a great product.

Loyal Lucas customer
