The eu insisted on adding alcohol to petrol at 5% concentration. This is known as E5 and is now the man petrol sold in the uk, blended to 95 ron.
Has any body else noticed the loss of power in outboards, particularly at 3/4 and full power? Along with the formation of a white deposit on the jets requiring regular cleaning.
Over the years since the engine was new (2002 ish) it has suffered a slight decline in max power. I have always put this down to the lower formulation quality of petrols.
Interestingly BP premium 97 RON is alleged not to contain alcohol.
Using the said BP fuel
With an Avon 3.2 Rib and Yamaha 8 4 stroke, not only is the engine smoother, but the boat achieves planing speed quicker and maintains planing speed on a smaller throttle opening, along with an extra 3/4 kn top speed.
Any body else noticed problems with the new poorer fuels we have to pay a kings ransom.
