Anybody have any experience using "Super Diesel plus"? I did a search and couldn't find out much about it. I have used this the last few fill ups and it has really made a difference in smoothing out the idle and the engine is running significantly smoother. Gas mileage showing a decent increase with the short time I have ran with it but not enough miles/time to really tell for sure. I wonder if this is safe to use routinly because I sure like The way this motor runs with this stuff in it. Maybe I just had dirty injectors but, I don't recall the motor ever runnig this smooth before and I only have about 8000 miles on it. says it contains Petroleum distillates and use at 1:500 I used 8 ounces per 30 gallons. I normally don't use additives but, may begin if this initial results continue and it is safe. I noticed Piers carries this line of fuel additives, not sure how pricey it is. hope this doesn't start another oil type thread.....
