    Best there is!

    <p>I have been using this product since the late 90's, it is the best I have ever found. I have a 95 Dodge Van with 3.9 v6 and 265,000 miles, IXL has kept it going, with out IXL I would be rebuilding the engine right now. But I don't have to as, IXL will take care of the rod and main bearing wear. This engine does not even smoke it burns very little oil, all because I use IXL.</p><p>Thank you for this great oil.</p>


    My friend recommended this

    <p>My friend and mechanic use the product already and they suggest I give it a try for my 7.3 tranny, which is slipping. I plan to get fluid changed first. It may save me a $3500 repair.</p>
