If it's the same slick 50 that was being made 15 years ago then I'll be happy. Had a truck that blew a rear main and I ran 4 quarts low on oil. Oil light came on and I pulled over. Luckily I had a Meijer around the corner. Stopped in and bought 2 quarts. Checked the oil and went back for 2 more. Best part was no engine damage. I swear by this stuff.

I used this company before on 2 stroke bush bikes, based on this I purchased this for my vehicle. Worked great. Will purchase again anytime.

Works, to recharge or enforce power train, drive power, torque turn ability increases by ten to 25 percent. It’s a powerful product, I switched to full synthetic oil, just to use this product once in a while or each or every other year, especially as it saves gas snd you get more gas mileage. I’ve been using it for ten years, with great expectations fulfilled. This stuff could take an old car or engine and polish it to race, or a new engine and make it smoother, I thought Mobil one was good, till I started getting more torque and better gas mileage and a smoother tide with this, slick 50 added in to the engine oil, that took me only one minute to add it

I've used Slick 50 for nearly 30 years and seen many benefits from it. I had an old '69 VW beetle that had no power and was amazed at the difference after using slick 50. I overhauled the motor but the engine seemed strained at high speed. After treating with Slick 50, the engine smoothed out and was clearly more powerful. Also, my dad drove a Ford van in his car pool for over 12 years and 400,000 miles. The motor >not once
