This product is fantastic! I have a 1996 Jeep Grand Cherokee with over 278,000 miles. I put this product in yesterday and noticed improvement immediately.
Good stuff. Running it on my track-only motorcycle.
My wife's 2013 Hyundai Elantra which has over 140,000 miles began producing engine noises at around 120,000 miles. I tried a few products mechanics recommended & products I read online that had good reviews nothing really made much difference. I saw this product at my local parts store & gave it a try. The results were not only immediate but last throughout the life span of the oil between changes. I didn't tell my wife and the first time she started it & drove it she came back home and said " my car isn't making that noise any more " I have used it since then at every oil change but once because the parts store was out. The one time without it the sound returned & I drove to the next town over to buy a bottle. Her car & my daughters car will not go down the road without from now on. Truly the best product of it's type I've ever seen & I've tried pretty much everything you can buy.
I use Hy-per lube in my 1982 Toyota 4x4 pickup every time I change the oil. The 22R engine that power's it has over 300,000 miles on it. I replaced the camshaft around 3 years ago and freshened up the head. Soon after I noticed the motor oil wasn't protecting the camshaft and I could see ( and measure ) wear on the lobes when I'd adjust the valves periodically even though I had been using a very popular oil supplement that was very thick & tacky. I had used Hy-per lube zinc replacement in my wife's car with excellent results so I gave your Oil Supplement a try when I changed the oil. I noticed right away the engine was much quieter & my oil pressure that was usually low once up to operating temps was now higher as well. The next time I went to adjust the valves I could see the wear on the camshaft had not continued & the time between valve adjustments has increased which is fantastic. We keep both Hy-per Lube Oil Supplement on hand now & I've gotten most of my friends to use it. It's truly a fantastic product & I'm a life long customer.
I am not on any social media, so I very rarely comment about anything to anyone. But I was so impressed with one of your products I had to say something.
I am 50 years old, so I have had many vehicles, boats, RV's, ATV's etc. over the years. One of my vehicles currently is a 2007 Infiniti M35 with 187000 miles. I bought it new and it has been an amazing car the whole time. Other than normal maintenance, It has been problem free. A little over a month ago I bought a new truck. So the Infiniti had sat in the garage over 2 weeks without being started.
When I finally decided to run some errands one day and use the Infiniti to do so, I started the car and for the first 6 or 7 seconds it was like starting a diesel in sub zero temperatures. The whole car shook and rocked violently! Obviously cold start/lack of lubrication. I had let it sit extended periods of time in the past with no issues, but I guess 187k miles has taken its toll. The next week I only let it sit one week. Not as violent of a start, but still not good with shaking and banging in the engine. The car seems fine, but I knew if I didn't do something, a few more cold starts like that would have done some serious damage.
I bought your Hy-per Lube Oil Supplement at a auto parts store down the road and immediately put into the engine. I only used half the recommended amount because I just had an oil change and didn't want to over fill too much. It sat for another two weeks before being restarted. This time...smooth as glass on start up! No shaking no noises or anything unusual. Thank you for making such an amazing product. I'll also add that I have never heard of your brand and if I recall I bought yours because it was a lot cheaper than most others on the shelf. Just wanted to take the time to say thank you for making a product (that actually works) and for a reasonable price.
