Hi Guys. I have been using Drew's Brew for the last 4 or 5 fill ups. Since the addition I have noticed a slight drop in
MPG. I was getting between 18.8 and 19.8 MPG. Now I see more like 17.1 or 17.4. Is this normal? I don't mind
losing a few because I believe Drew has a great brew with maximum lubrication. I just wanted to make sure I don't have
a problem somewhere else. I will be changing my fuel filter soon, and maybe that will help. Any comments or suggestions
are appreciated.

Thanks.

 

it does sound like your filter is getting close to the end of it's useable life.

 

I think I'm about ready to try a mix of PS and 2 stroke since I still have some of both. After that, if I'm still not happy with the results, I think I'm going to try some Lucas

 

Just one thing to remember is that with PS you can have too much in your fuel and that can cause you to get lower fuel mileage. I know some say it’s not possible but I saw it happen years ago when I drove long haul. IMO you should not use more then 1 oz per 3 gallons of fuel and only to help clean carbon off your injectors.

Personally I no longer use it (I use Lucas as it does not contain any Naphtha like PS does) as I have yet to find in the data available as to what they are using to lube the fuel system. As I understand the data on PS, it will not lower the scar wear in our fuel system so I can't see how they can claim that PS adds lube to the fuel system if it can not lower scare wear.

 

How many miles are on your fuel filter or air filter? I change my fuel filter every 15,000 miles.
A few weeks ago I mistakenly added way to much PS and MM ( Drew's Brew) to a tank that I thought had less fuel than it actually did. Consequintly, the engine ran rough and smoked alot at idle till it warmed up. After burning the fuel out of the tank, I filled up with fresh fuel and the problem mostly went away.
The shop I deal with, Meridain Fuel Injection strongly reccomends a product called Stanadyne. I plan on getting some soon to try it out and will post the results.

 

Thanks for all the responses. I know that I take extra care to make sure I run the tank to within 4 to 5 gallons of
empty to make sure the next add of Drew's Brew and the fill up of fuel is as correct as possible. I also take extra
carewhen Imeasure out the amount of PS and MMO. The fuel filter probally has between 5000 and 7000 miles on it.
The only other thing that I forgot to mention (Sorry) is that I use the white bottle of PS. I thought it would be easier to use
the white bottle all year around instead of switching from gray to white during the year. Do you guys think I should switch to
the gray bottle for the summer and see what happens? I will change the fuel filter this weekend and see if that helps.
Thanks again for all your help.
