[QUOTE="jimdawg185, post: 1202798, member: 757"] Our multi grade 704/703 and 9919/9920 do have the modifier in them the Duolec does not. The 9920 is what I run and it works great. But it is on par with all the other FZG tests out there. The only advantage to 9920 and 9919 is the lower pour point. But unless your are way below zero there is no real advantage. I will be switching over to 1606 Duolec when I put my lockers in. One of my customers is Venom Motorsports in Grand Rapids MI. ARB has warned them to not use synthetics with their lockers. This was our solution. I will say that the 9920 and 9919 will last really long. We run it to 750000 miles in our OTR big rigs. Duolec and 703/704 we run out to 400k. Duolec will separate from water like no other as well. Its stupid how good this is at it. [/QUOTE]
