X-tra Lube oil treatment with MBL technology has been around since 1983. So it's not surprising we got this note from a customer who's been using the oil treatment for almost 20 years now:
Been using xtralube (sic) on 1994 ranger trail trailer since 1993. I have never had 2 take the bearings apart. GREAT PRODUCT. I tell all my friends of this. THANKS
