David, I won't use Duralube or Prolong. From what I have read and heard Duralube can break down over time due to heat and contaminants in the engine to form hydrochloric acid. That is not good for metal. Prolong recently got slapped by the Federal Government for false advertising and Consumer Reports did the same test that Prolong does with very different results. I have been using Militec-1 for over five years, and it works. It is one product with many applications. You can check for more info. No I don't sell the stuff. I buy mine on base for a lot less than the distributors sell for. Here is some food for thought on mileage dropping. I just had to replace the tensioner pulley on my 87 9000S. I had been wondering why my gas mileage had dropped over the last two months. Now I know why. The pulley bearing locked up a few days ago and broke the belt. I put the new pulley in this morning and the mileage is back up already. Ken Washington 87 9000S 87 900S 83 900T
