February 12, 2004I use AMSOIL Synthetic oil in my big diesel I also use it in my gas powered 1980 GMC K-2500 Sierra Classic and in my 1994 Blazer.
I also use AMSOIL synthetics to lube tranny, transfer case and rears in all my vehicle. AMSOIL was America's First Synthetic Lube, they were on the market long before Mobile 1 and all the other followers. They also have a lot better selection. If you are interested in seeing what they all have for your diesel powered HD just go to http://www.amsoil.com and follow the promps to pickups. Goodluck with what ever you decide.
February 13, 2004My truck is still fairly new so I use whatever the owners manual suggests as to not void any warranty. Synthetics will not void the warranty, however, with a 100k warranty on my Allison, I figure, as long as I follow the warranty manual, I should never be turned down by the factory in any failure. So far, I have only had my dealer do the "regular maintainance" to keep within the warranty perameters.
This might be "anal" of me, but I figure if they do the scheduled maintainance, I cant be blamed for a failure due to my choice of products or service suggestions.
I think synthetics are fine to use as long as it meets the manuals recommendations. Just my
