YES! The fuel blend will definitely affect mileage and performance - more ethanol - less mileage, percent for percent almost. It's exacerbated on a ONE cylinder engine because you FEEL every firing cycle, too .... one or two lean hiccups in a row and you are going "WTF?" ................
How does it affect performance though.
Are we robbing our engines of real gasoline to psychologically save a few cents per litre and end up burning more than those few cents we saved?
RESULTS OF LUCAS INJECTOR CLEANER & UPPER CYLINDER LUBE / VALVE LUBE IN MOTORCYCLE Nobody replied 'yes' to my question if any one had used the above product in their motorcycle. So, I tried it in my G5 - turning it into a guinea pig. I added a little bit to my fuel tank a few days back. Since then I have covered over 150 miles. The results are pretty good. These are my observations -1. The valve noise is less.2. The idle is more stable.3. The fluctuations in idle engine rpm, due to EFI doing its 'thing' are less.4. The pick up is better.
How much of that little bottle did you put in? I've used it in my truck and did notice improvement in pick up.
