BG44K: Gas mileage increases, then decreases..

[elwesso]

OK... Whenever I use BG44k, I usually get about 15mpg (or did) for about 3-4 tanks.. Been about 7 tanks after my last BG treatment, and I got 13.6 last time (understandable about how I drove it over the weekend... )

I remember Q45tech saying that if it does this then its time for a rail flush.. is this correct, and will it solve my problems.???

I am DETERMINED to get 17mpg this summer in my current driving status...

I only got thinking about this as I got a gift of BG44k from a friend... You know who you are!!

Wes,

You're not gonna get 17mpg with multiple runs at WOT daily. I think Dennis did say a rail flush was in order. I'll search for it.

Do the rail flush.

I got that thread.....

When one Q gets 22 and another 24 and another 20 mpg at cruise [assuming exactly the same conditions and same brand of fuel in the same city]........you always start with fresh O2 assumming they are over 3 years or 50k, then a rail flush, then an induction clean and flush, a MAF clean, a basic timing check, an isle and running vacuum check, a cat back pressure checks [while you are changing the O2 [using this port to measure backpressure at idle, 2000 rpm and WOT]............lots of these things are never done!

I'll call up the nissan dealer and see if they do them.....
