finnally have got something to help out with n-14 injectors and today poor fuel,last 10 months/100,000 miles have been useing martha mystery oil for fuel additve on my 96 500 red head, much quieter engine without any injector problems,plus more pedal response,better fuel milage( about 70 miles more per fill)took about 2 weeks of useing it to get system cleaned up but after that have not had any problems one quart to half a gallon every other fill has been working fine. computer mpg for last 24,000 miles at 6.68 mpg

yes it is marval mystery oil,been working very good out of all things we have tried ,do the math if i can get another 200 miles a week out of the same gallons its worth the 15 to 22 dollars a gallon for the oil,and you can tell if i dont put it in for a week she starts to get a litle rougher running.

Do you think it "dyes" the fuel enough that you will have any problems that way?

seems like one i got the system cleaned out you could get by with a quart every other day, as far as seeing the dye in it it wash hard to see it in medium green fuel. ive used dextron before and that dyed it more than this,always carry bottle with so if asked they could see what i was adding, thats in putting 130 -150 gallon on at each fill,if you have been in it long enough you can remeber what it was like to put your hand in the old diesel and still have that oily film on your hand,you get the same with marvels,ive run hard this summer even in the heat,and no injector problem at all this summer.thanks jr

I know what you mean about the old and the new diesel.. The new stuff sure penetrates your skin, especially when hot. It wipes off different, actually cleans, and leaves your skin dry feeling.
Thanks for the info on your results with Mavel Mystery oil.

going to try something this week as to the concern of the dye ,middle of week after adding marvels ill stop down the road and pull a north carlina tampon prob on it and see what i end up with,if no red on the tampon i dont see any worry about it.
