Good product
A great fuel additive for diesel engines. I noticed a significant difference in how smooth the engine idles and runs when using this additive. I would have given it 5 stars if the containers had ounces markings on them. I typically fill my tank when it reaches 1/2 empty and therefore I only need 4 ounces. It would be nice if the 8oz bottles (actually, all container sizes) had a translucent fluid level indicator with oz markings.

It improved my diesel system performance
Recommended by the dealer for my newer model GMC diesel pickup and so far it has proven itself to work. When the engine seems to be running a little more sluggish or the DEF system doesn't seem to be operating as well I add a bottle of this, to the fuel tank at fill up and everything seems to improve. I've had my check engine light come on for emissions system issues a couple times and this has helped resolved the issue. It's a little bit expensive so I add it once every 4 to 6 weeks at the most.
