PetroLabs would like to put their money where their mouth is and let our additive speak for itself. We have had many customers tell us that our additive fixed their injector problems.

We do not claim that our additive is a fix-all for every injector problem, but we do firmly believe that our additive will save the life of your injectors & injection pump. Plus, your EGR valve will stay cleaner, DPF system will not only stay cleaner but will do so with less regens, all with no sticky residue left on the particulate filter. When you use our additives, your engine will stay cleaner and last longer, you’ll increase fuel mileage and save on costly engine repairs.

To prove we stand behind our product, we are offering to help individuals with their injector issues to see if our additive could be the solution to your problem as well.

If you currently have an injector failure issue, we are offering to send you free selected bottles of additive to try, all you need to do is pay for shipping. If our additive repairs the issue, like we suspect it will, we would request a positive testimonial letting us, and other future customers know the truck make, model and year, what the problem was, and a short informative story of how everything unfolded.

If you qualify as a candidate, we will give you specific instructions on the mixing ratio.

I drive a 2015 GMC Sierra 2500 HD with the 6.6 liter Duramax diesel engine. Recently my truck developed a check engine light. The code was a po2d5 which states this. The engine control module (PCM) has detected that the fuel and air balance is off in cylinder 5, and that fuel injector offset learning has reached its maximum limit. The balance rate on the cylinder 5 injected when warmed up was hovering in the 2.5-3.5 range consistently. Which is a sign of a failed injector. I got a quote from a reputable shop to replace the injector. The quote was about $2,300 to replace one injector. I thought that was outrageous, so I wanted to look for a different route. I ended up getting in touch with an employee of Petrolabs. I explained my situation to him, and he pointed me in the direction of one of their additives, Diesel Power. It is a fuel additive that not only adds lubricant to the fuel system, but it cleans while doing so. He instructed me to run it very concentrated at first. After just the first tank of diesel with the additive in it I saw the balance rate of the injector 5 start to drop, and after two tanks with the additive it was running consistently near zero where it should be. I am now running the additive in the suggested amount for treating the size fuel tank I have, and still the balance rates of my injectors are staying where they should be. I firmly believe that the additive does exactly what it is advertised to do. It cleans away build up on the injectors and it adds lubricity to the fuel system. That lubricity is also a plus giving me some peace of mind about the common failure of the cp4 high pressure fuel pump in this particular truck model. I have always been skeptical of additives in the past, thinking they were just a snake oil that companies sell you to make money, but after this, I am a believer and now a loyal customer of Petrolabs.

I put some diesel additive in a Lincoln 300 welder / generator with 3760 hours. It starts right up serviced 30 hours ago. When it was running, things laying on the frame and would vibrate off. I put 6 oz of additive in less than 5 gallons of fuel. Within 5 minutes it smoothed out with very little vibration. I am going to put 5 gallons of fresh fuel in it and add another 6 oz of additive.

I’m the original owner of a 2002 Chevy Duramax HD 2500 with an LB7 6.6 engine. The LB7

engine was one of Chevy’s first 6.6 engine design and they placed the injectors in a poor location which caused early injector failure. Chevy gave me a 200,000 mile warranty on the injectors because they knew they had an issue.

The first injector failure happened around 50,000 miles, the second one happened right around 100,000 miles, the third happened around 150,000 miles and the fourth failure happened in 2008 at 197,000 miles. 2008 was the United States financial collapse and Chevy was in terrible financial trouble. Chevy refused to fix my injectors again, so I had no choice but to pay out of pocket.

The injectors failed again at around 250,000 miles and I needed to find a solution to my problem. I ran across PetroLabs Fuel Additives and one of their sales team wanted to test their additive and see if it would fix my issue. I was very skeptical but willing to try.

They gave me 6 bottles of Diesel Power Additive, they instructed me with a very aggressive treatment ratio. By the way, I was blowing white smoke at idle, raw fuel was passing by the seals at idle and I was getting horrible fuel mileage in city driving, I did much better on the highway when the injectors were under pressure.

I’m not exactly sure at what bottle I stopped blowing white smoke, but I think it was my third bottle. It is now 2024 and the truck currently has 380,000 miles on it with the same injectors I put in at 250,000 miles. I’m a true believer in Diesel Power additives. A full injector replacement at this time would probably be around $7,000.00 or higher.

I don’t go by the bottle recommendation, I usually dump one full bottle every other tank or sometimes every tank because I’m not willing to pay someone $7,000.00 to replace my injectors.

I purchased a 2007 Isuzu bobtail truck 4 cylinder with a blown motor. The truck had been sitting for a little over a year when I purchased it, and it had a half a tank of diesel fuel in it at the time.

I rebuilt the motor and put it back in the truck. I didn’t like the fact that the diesel fuel was so old, but I didn’t want to drop the tank and drain the fuel either, so I decided to start the truck with the old fuel in it.

I got the truck started and it was idling rough, I made all the adjustments I could, and the truck still idled rough, so I figured it was the old fuel causing the issue. I instructed my helper to add a full bottle of Diesel Power additive into the tank while the truck was running and nothing happened. So, I had my helper pour in another full bottle of additive and as soon as he did, the truck started idling smoothly. We just looked at each other as if, “did that really just happen.” To say the least, we were both surprised.
