Product Description

A superior automotive lubricant (NOT an additive), dispersing billions of microscopic particles of graphite that enhance the effectiveness of motor oil. When added to the crankcase of an engine, Krex Graphite Engine Lubricant adheres to all of the internal parts of the engine, protecting and lubricating all the engine's vital moving parts: pistons, bearings, valve stems, and lifters. Today's advanced automotive engines reach temperatures as high as 1,250 degrees F, yet standard motor oil begins breaking down at 350 degrees F. (Even the best full synthetic oil breaks down at 500 degrees F.) Thus, only graphite, which can withstand temperatures up to 5,000 degrees F, can fully protect engines at these extreme temperatures. In addition, Krex Graphite Engine Lubricant improves engine compression, reduces energy consumption, and increases load carrying capabilities.

This engine additive helps with engine noise and vibration

This engine additive helps with engine noise and vibration
This is a review of Krex Graphite Engine Lubricant. I have been using this stuff from about 60,000 miles. Now I'm at 140,000 miles on a 2006 scion tc. My engine would knock and vibrate at stops before I started to use this additive. Once I used it, all the noises and vibrations stopped. I was given this additive from a friend's father and I didn't know how expensive it was. Now that I've used up an entire case and I'm down to the last 3 bottles, I'm looking around and this stuff is like gold. I've been using it during every other oil change and it seems to bring my engine back to a purr every single time. I've let some friends of mine take from the case that I had and they've said the same thing with other makes and models of cars. If there's anyone out there that can list the ingredients for this product, I'd sure like to know what's in it. I am neither a representative or have any affiliation with Krex Graphite Engine Lubricant company or any subsidiary. Thank you.

5.0 out of 5 stars Yes, it works very well.

I remember GM maintenance using this product in one of my trucks and that engine ran smooth as silk. So, I decided to order Krex and try it out.
I have a 2016 GMC with the 3.6 liter direct injection engine, and I use Valvoline Synthetic oil.
I added Krex today with engine running and drove it about 15 miles to make sure it had coated the inside of engine well.
I didn't notice any change in the sound of the engine, as it already runs very smooth. I did however notice the fuel mileage started getting better. I watched the instant mpg readout and was amazed that it was getting 34 mpg on a straight flat road set on cruise for 65 mph. I went up a slight hill which usually drops the mpg to around 14. The readout held a constant 27!
Is that enough to let you know that YES, this product works very well.

5.0 out of 5 stars “snake oil” turned solid (black) gold
Reviewed in the United States on October 21, 2023
Verified Purchase
I originally purchased this product to challenge an argument I saw online stating this product is snake oil. I didn’t know how impactful of a change this stuff would seriously make- even my friends are in shock. I use roughly 3/4 tablespoons of this stuff in a motors oil and the compression is crazy! low end torque and power is noticeably increased especially initially- felt similar to when I got a high flow exhaust compared to stock with the low end (of rpm range) power difference. I’m glad I’ve been able to disprove what I saw online with my own experience and what my friends who’ve got some added for them said. only concern I heard from friends is the color appears off putting but if you trust the process the results speak loudly. From now on I will probably always put a little Krex in my motor oil to help the motor run more efficiently.

3.0 out of 5 stars I don't think this stuff should be used
Reviewed in the United States on September 27, 2023

I have found that the graphite messes with the spark plugs, and "cakes" the engine parts with black stuff. Some people think that it will clog the catalytic convertor as well. I am deciding to not use this brand of engine lubricant enhancer.

5.0 out of 5 stars Krex Graphite motor oil additive works as advertised.
Reviewed in the United States on May 12, 2019
Verified Purchase
I have been using Krex Graphite oil additive for many years in 12+ different vehicles. Results have been quite uniform, gas mileage increased by 7-10%, oil temps decreased by 5-8 degrees, starting will be bit quicker, and engine noise will be reduced, (ymmv). Works in any four stroke motor, air cooled engines seem to really like this product. If one adds the appropriate amount of Krex to a group five synthetic motor oil, then in this user's experience, maximum efficiency of operation will be achieved.

5.0 out of 5 stars Phenomenal product has worked excellent for me and for others!
Reviewed in the United States on December 8, 2019
Verified Purchase
I have had multiple vehicles multiple brands over the course of my career as an automotive service advisor and technician. With this product I have had the ability to resolve certain internal engine issues. For example lifter ticks on multiple GM vehicles. I stand behind this product. It has proven to me time and time again that it works. Reduces engine wear. Promotes better engine lubrication. I have been told that it has also increased fuel economy on certain scales. Also my brother's truck which is a 2004 Ford F150 has over 250000 miles. It started burning oil. We added in a bottle of Krex lubricant. Which helped reduce his burning oil condition. I cannot find it in any store. Amazon is the only place I can find it. I always order the 6 pack. I know I will use it in every vehicle own. I recommend it on the ones I don't! Phenomenal product!

5.0 out of 5 stars The best Oil Additive Ever.
Reviewed in the United States on April 20, 2015

Excellent additive. No hype. I have been using it for 17 years. Several years ago my wife ruptured the oil pan on her V-6 Ford and drove 156 miles home with the oil light on. A new oil pan and five quarts later, the car started and ran until she was rear ended 3 years later. I swear by Krex and it goes into every car I own.
