I find my 7.3L starts more easily in cold weather when I use AR6200 in the fuel. Forgot to put it in a couple of weeks ago when it got down to 15 degrees
at night. Next morning couldn't get it started. Waited until later in the day when it was warmer, added the AR6200 and it started right up.
Definitely improves mileage in gas truck. Use in diesel truck because I have auxiliary tank and store fuel for months with no issues. l
Use it in my trucks & motorcycles
We use this in our diesel trucks and in our Cayenne. Notice a pretty substantial increase in gas mileage and in general, all of our vehicles run noticeably smoother. Bought a few bottles of these as Christmas stocking stuffers for my husband. Pretty sure he’d bathe in this stuff if allowed. Thank you for a fabulous product!
