My name is Rani, Chief Mechanic from R&S Performance. We take great care in preparing our vehicles for our four trips. That's why we choose all three lubricants, four hour four by four bikes and ATVs. Our four is where we see the alternates and peak consistent performance of all three lubricants at the end of the road. I recommend all three lubricants. Ultra lubricants, world-class lubricants for tropical conditions, distributed by Industrial Supply of Guyana Inc.
