Sorry for the repost earlier, but in my vw Tdi I've noticed a 2-3 mpg loss, but I'm only on my second tank. Takes awhile to fill up when you can go over 700 miles on a tank of fuel. My X5 35d has gone from all highway miles to all city miles at the same time I made the switch to HPR, so hard to tell.
Last tank of HPR in th X5 35d was 17.5 MPG all city. |

Regarding HPR triggering regents less despite having same or more soot clogging up the filter, I don't buy it. This stuff is shown to produce significantly less particular matter than D2. Do we know exactly what triggers a regen? How is PM mass measured?

Hre ff01 19 inch with new hankook tires installed with Tpms switched for 3100 And an 80 tire rebate on top of that. I was going to order the forgestars but the wait was 2-3 months. They offered me a nice discount on them so I took them. I am also noticing decreased city mileage and increased highway mileage. I track my mileage with an app and am only going to be fueling from hpr from now on unless a take a long trip, so I will report back with results. |

multiple factors; another theory is that post injection temps dont get as high thus less matter burned? who knows. my primary concern if I were running HPR would be gumming up of parts similar to B20+ concentrations, but I have no idea if thats a risk or not. |

I have run HPR for 1000 miles and no real difference in MPG at all. The engine is just really quiet and smoother. I also get no more pending codes from JBD at 100% so far. Hopefully there will be less carbon problems if i run it full time.

I'd be happy running this stuff with 0 improvement to fuel mileage, just less particulates / carbon build up. These cars get great MPG when they're clean.
Unfortunately its not sold on the east coast.

I got tank on my way back from LA to SF. MPG was the same, however the car is quieter, not my imagination I used DB iPhone app before my first tank, drove the car for 50miles and took the measurement again. It is 5db lower. I did use power diesel ad, just to add more lubrication although HPS Diesel supposed to fine. Got another tank once I hit Bay Area. We will see how it goes.
