Diesel Additive

[filrupmark]

What type of diesel additive would be good for keeping injectors clean,moisture control and maybe added cetane & lubricity. What do you use.

My book says not needed so I don't. So far so good in 10+ years and 162+k and counting. JME.

I use Diesel Keen in the winter as my truck sits for weeks without being used. Summer nothing.

Sorry double post.

Trouble maker! You opened a can of worms with this...most of the answers you get will be preference based on nothing but opinion. Good luck. The folks that make it won't give you straight answers, and the last study done (Spicer) is getting old.

FWIW...you probably are better off with the right additive. As best as I can determine, the Bosch injectors are designed for european spec fuel...not the US spec...which has less lubrication. Do your research and then feel your way through....best you're gonna do.

The biggest no-no is alcohol based fuel additives and so called emulsifiers.

If it helps, I used Stanadyne performance formula for years, but just started using Opti-lube summer +. Stanadyne was fine but a little light in the lubricity department. Not sure about Opti lube summer plus...hoping for a new study.

Holy price point Batman. 1oz per gallon. At wallyworld $9 a bottle that's $20 a fill up.

You didn't mention the year/make/model of your engine… which could affect your choice of additive (if any).

I add Power Service Diesel Kleen to every tank for my personal truck and also in my company's fleet of (six) diesel vehicles.
Sliver in summer. White in winter.

I used the stuff available at Wal-Mart sold in white square plastic bottles. Forgot the name but the bottles are white with black and red print. With the garbage they are peddling for diesel now, the stuff may help fuel mileage and driveability. I sure wouldn't pay for an additive unless it did something concrete.
