I use Delo 15-40 in my 97, but in the cold Kansas winter months like to use PB2000 because it is supposed to flow betteron a cold start. Was wondering: Could you use say 9 qts of Delo & add 2 or 3 qts. of Amsoil? It's supposed to be compatible with other oils. At least this way you would know what the percentage of synthetics blend is. And for those of us who still like to change the oil & filter at 5,000 miles, we could still afford to do so... ... ...
