Stanadyne Performance Formula Diesel Injector Cleaner-Qty 2, 16oz Bottles # 43564

I added it to my Racor filter and it cleared smoke from injectors in 10 minutes.Checked this morning with cold engine - no smoke.

Arrived perfect, and great as expected

I am a fan of Stanadyne products. They work really well when used as directed, and allowed to work in a fuel system for a long period of time. I have seen a noticeable difference in pilot injection flow rates, and balance rates.

I've been using standardine products for years now and they really do a great job. My only complaint was one of the bottles leaked in the Box. Not sure how or why because none of the product seemed to be missing.

Been using in my 6.7 Cummins/Dodge roughly 4 times per year and/or after extended road trips or heavy hauls. I use one 16oz bottle per tankful or a bit less (I’m running a 50 gallon tank) Easy peazy. I also use the lubricity formula one tank full per month. I have read the Stanadyne products are Cummins/Dodge recommended. So far zero issues at 160K.

Truck is starting easier and definitely a mileage increase I don’t drive alot so it’s taking time to work but I’m just getting through the 1st half of the 1st bottle and I’m already starting easier and seeing a mileage increase yeah I needed it

I keep track of milage on my 2006 Silverado LBZ with every fill up to accurately track fuel milage. I ran one tank with a double shot of this product and saw one more MPG. Ran the next tank with another double shot and got an additional half MPG on top of that. The increase in MPGs has stayed since then, it has more than paid for itself I plan to use it a few times a year. I run the performance formula with every tank as well and I notice the engine runs quieter.

This stuff actually seems to work. I would say it's the best I've used, but I always order more than it says or recommends. Use double the amount at full up for best results...
