The new product in the black bottle outperforms the older grey 16 oz bottle. **Q: Is this a thick liquid or is it thin? I’m worried about it changing oil viscosity** A: Hi and great question. Using the BestLine Engine treatment does not change the viscosity of your oil. We use a 20 weight base oil and your only using 12-ounces for every 5- quarts of your regular oil. **Q: Can i put two bottles of this product in my truck engine 5.3?** A: Hi, yes you can add 2 bottles for even better results. The dosage rate for daily drivers, not high performance, is 1 bottle per 5 quarts of oil. If you want the best results use 2 bottles per 5 quarts of oil, that's what we do with our high-performance and race cars.
