Dennis and Carol,
I run GM diesel fuel conditioner. I buy it a case or two at a time and the shop sells it to me $2 over their case cost for buying the volume. This is the first diesel motor I have run conditioner in. Since I started using the conditioner I have logged over 9,800 miles and things are still going great. Hope it stays this way...
I was in the Big R a few days ago and noticed they had a large selection of diesel fuel conditioners. One might want to check out their selection if looking into it.
