I just recieved 1 quart last week to add to my 4 vehicles. 1st was my '02 Silverado 2500hd w/212k hard miles on it; bank repo 3 years ago. After adding 6 oz to oil & 3 to trans it runs much smoother after 50 miles & rpm at idle is 600 now vs 800 before. Put 4 oz in my '13 Prius w/145k miles & startup is smoother & less noisy within 2-3 seconds. Just had timing chains/guides replaced on '04 Ranger w/182k i just bought & its smoother to. Addzd 5 oz to my '74 Valiant with /6 & its quieter also. I have bought so many additives over my 45+ years of owning various vehicles not really knowing if it works or not but PROLUBE is a Game Changer with proven results and I will be a customer for life! I have just 1 oz or so left for the oul in my old 25 gallon air compressor.

After watching countless TikTok videos comparing it to other products I will admit, I watched one video comparing Prolong VS Prolube and it was the only one that did just as good. I was due for an oil change on my Audi A4 So because it was available nearby I purchased that first but was $20+ which was only a few OZ just to try something comparable first and definitely noticed a difference right away. After that, I was sold and went online and made a purchase. I’ve used it twice now Definitely recommend, it is just like what you see in all the videos and reels online and the Proof is in the puddin lol

I started using Prolube a few years ago in my 1969 Cutlass convertible with a 5.7 V8. It increased my fuel mileage from 10 to 14 constantly since I started using it.

So in my case it is doing exactly what I expected it to do.

Plus the customer service is absolutely amazing!

Thanks Prolube

I initially approached Prolube with a healthy amount of skepticism regarding its performance claims. However, after adding it to my 2015 Nissan Xterra Pro-4X, the results have been undeniable. Within just one week, I’ve noticed a significant reduction in idle noise—the engine is remarkably quieter. Additionally, throttle response has improved, giving the vehicle much better 'get up and go' during acceleration. I am currently monitoring my fuel consumption to see if gas mileage improves, but the immediate mechanical benefits are already impressive."
