510023 Regane High Mileage Fuel System Cleaner, 6 oz. (Pack of 6) (510023W-6PK)

We have older cars with higher mileage and this stuff seems to do its job, we've had no issues and no complaints. Very easy to work with!

Works great for cleaning fuel system. I use it in all my gasoline cars and trucks.

Good product good brand

Reorder additional. Package had no leakage. Great value for the price and quantity. Seems to help with my mileage at 178k, using every 3k.

I started using this when my Audi was burning oil from a problem with carbon buildup around the piston rings. Tried other additives with no luck and I use top tier fuels. Tried this on a friend’s recommendation and it cut down my fuel consumption and increased my gas mileage. I have been adding a bottle every other fill up for the last 6 months and sustained my results. Very satisfied and will continue to use.

I used 6 of these every fill up crossing the country. My Explorer has about 80K miles and although I didn't notice much from off ramp to fwy., when I arrived and started driving a few days later it was like a new car., fast starts, responsive, and my mileage has gone up.. performance improved significantly. Yep, impressed., a 29 dollar tune up.

Because this is one of the few products that I am aware of that contains PEA's (Polyetheramine) I use this product in all my vehicles every now and then to clean out the injectors and intake valves to prevent carbon build up.

I do my own oil changes on me and my wife's car and I add one of these with every oil change in the beginning I did three in a row the gas mileage improved
