Tom said:its near crazy to suggest a car with optimax would be faster in real world situations.
Tom said:And if argos sold the fender why wouldnt you?
I buy my car insurance from a pachyderm!!
Tom said:Wish there was a way to actually prove what your saying is correct.

MarkCup said:I've never run out of fuel on a track day, and I normally get home as well, but in 3 days at Goodwood over 3 weekends, the one weekend I ran Tesco 99, I ran out on track (stuttered and coasted) mid afternoon. Read 11.7 mpg compared with 14.2 and 16.8 (rain all that day).
Without blowing my own trumpet, I'm an advanced driving instructor as well as a track addict, and practice what I preach. My daily runs are consistant, smooth, and I cover 350 miles per week, so I'm probably about the best guage you'll get for a fair comparison

The placebo effect is a wonderful thing!
davebigfoot said:So why do you think Renault recommend 98 RON for the clio sport? See the Elf sticker in the back window of every clio sport? Renault and TotalFinaElf have a long established partnership.... but Total don't have a 98 RON petrol. How thrilled renault's partner must be with that bit of team play. Still, I'm sure renault had no good reason for doing it, eh?

gazcaddy said:Optimax for me, recently I have tried a tank of Tesco 99 ron. doing similar driving I have got about 4-5mpg less than usual! anyone else had this?
JBarber said:I'm also a chemical engineer and I haven't really noticed any performance or economy benefits with Optimax vs 95 or Tesco 99, although I do use Optimax if I get the chance as I too have read about the long term benefits to the engine.
Also, I don't really understand these comments that you need to give the ECU a couple of days to "get used" to a fuel change, doesn't it recalculate 1000s of times per minute like a normal computer chip?
cliokhunt said:It's called a knock sensor, and it takes a tank or two for the ECU to adjust the fueling to suit the grade of fuel be it for more or less performance. Mixing two fuels in a tank does nothing bad. If you mix 96 with 98 octane you will in essence acheive 97 octane.

BTW, Clios don't have knock sensors and I bet none of you could tell whether your cars were running Shell 95 or Shell 98 performance wise. However if it saves you 5mpg it might work out to be worth it in the long run.
lucky u! it probably costs less over there as well?Weeman said:100 octane German optimax for me.
