I doubt this thread will keep from degrading into an oil-brand barfight, so I will get my reply in early. If you want to continue using Amsoil, you can order from their website. If you use enough, you can get a preferred customer discount. Otherwise, if you want to continue running synthetic, Mobil 1 Truck and SUV is diesel rated and available at most Walmarts. I used to run Amsoil in my Dmax and found it to be a good oil, but when Mobil 1 T&S became available at Walmart, it was simpler just to get it there so I switched.
