Just received it in the mail. Added the Turbo Maxx in with my oil (6 oz). Drove approximately 70 miles and really noticed my engine running quieter than before. It's too early to notice any gains in power or mpg's but so far so good. I'll definitely add another treatment at my next oil change. As far as the C-4, I really haven't noticed a difference yet. Could be because I've been using Opti-Lube XPD for the last few months but I'm always looking for a better fuel additive solution.

Added turbo maxx oil additive into to the new oil at oil change for both engine and gearbox, no faults or problems with the car, hoping to get many more miles using these products. Have driven 850 miles since oil changes and it definitely felt smoother and sounded quieter within the first 50 miles. Oil temp shows 2 degrees lower than it used to before oil changes. Average Fuel consumption is showing slightly better figures but more so from a much easier cold start I think. I would recommend the oil additive and with the test results I have seen produced on you tube the fuel additive can't be doing my motor any harm either. I had no problems to try and fix with these additives, I just wanted to help maintain my taxi to do many many more miles. I also changed brake fluid and coolant and all filters, it feels and drives like brand new, maybe even better!Read full review
