I put this in my 2011 Buick Regal with 112k miles and it made it run like a champ! I use it now in every third fill up!

I have V 8 jeep cherokee with 200.000 miles. Engine used to shut off whenever I’m fully stopped in traffic or on a traffic light. It has been six months since I started using this product and never again I ran into that problem again, add to that the smooth engine-run. I use it every other fill up. Great product and the price is great.

Got it quick and as described. I don’t know if this stuff actually does anything but I know I feel better after using it!

I’ve been using this product for many many years and as long as you continue to use it it works great. If you’re having fuel problems you may want to get something a little stronger but for regular maintenance this works well. Six pack saves a bunch of money.

Definitely helps with smaller engine (4stroke) maintenance. I’m sure with vehicles as well.

My Jeep started to idle rough where it had been smooth as silk. I’ve added 4 so far and the idle does seem to have improved some. Hopefully with a few more it will get even better.
