Krex Graphite Engine Lubricant 4 Fl. Oz. - 6 Bottles

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.

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!

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.

A+

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.

good

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.

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.
