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

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 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 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.

Extended the life of my car engine motor. Protects friction on engine parts.

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.

Great

Should be a good item to reduce engine ware.Time will tell. I like the idea of a better lubricate.

I used this all my life, it truly works. This stuff cleans sticky lifters and the graphite is a wonderful coating for internal parts, also door locks!
