Great products

Fuel additive seems to be working. Seems to be holding good mpg ranges and start ups are smoother in morning with temps getting down near 0. Will buy more again soon !!!

Never got it

I’m sure it’s great but I never received it. Probably a problem with the post office. Had to resort to the competition for the time being. First thoughts with order was the shipping seemed a tad long considering the average time is 8 days on most orders. I’m glad I got the review email though, it reminded me I need to call for a refund or new ship.
