Opti-lube fuel additive
Started using this in both diesels last year and I highly recommend it. I also bought their cetane boost. It works!!! Ran into a 35 year diesel mechanic and he also said it's the best. Call their 800 number and they answer, speak English, Saltlake, and are very helpful. Very happy. I added to fuel last fall and runs fine this Spring after sitting all winter
