Tesco 99 Ron Petrol - Avoid???

[Kevin Wood]

For the same power you need more Tesco 99 RON as the Ethanol has less energy per litre than petrol.

Very true. Take the extreme example and compare fuel consumption figures for petrol and E85 biofuel for cars that can burn either!

Less energy per litre means less power as well, unless the power you gain by having a higher octane fuel is greater than that you lose by "watering down" the petrol with ethanol.

In other words, unless you've got a high compression or turbocharged engine that will retard its' ignition and / or limit its' boost on lesser fuels, you might as well not bother.

Then again, it sounds like supermarket 95 RON has a good dose of ethanol too.

As we may take the beans back to the shopkeeper, can we pour the petrol through Tesco's letterbox?

Just kidding of course, but, it is the first point of contact that always gets the brunt of the customer.

I sincerely hope that if any of the guys on here who've been affected, get put right soon with minimum disturbance..

Silicone implants are now being blamed for cars cutting out and running rough, do any of us on here have implants, I don't, my Omega's running OK though,,,  see the link C&P'd from BBC web site http://news.bbc.co.uk/1/hi/uk/6409025.stm

"Meanwhile, an AA source told the BBC traces of silicon have been found in petrol taken from the cars. "

Sorry for the previous, sick sense on humour, however it's alarming..

Asda fuel seems to be 50% water and returns awful MPG

I average 25mpg from Asda fuel....

Compared to what, say on Optimax, or normal shell fuel (for example) ?

About same from normal BP.

Did try a couple of tanks of V-Power just before Santa Pod last year, but economy dropped as I wanted to see how much quicker is was on that stuff....

some real horror stories.

i have always used high octane shell or bp with a little squirt of fuel additive

no budget fuels for my omega!

If a petrol company wants to put additives in our fuel (like planet saving ethanol) it should be clearly marked at the pump. Greenergy!! who the hell are they?? Until now I never knew who they were, let alone putting GREEN s**t in my fuel. TONE should concentrate on China & the States before buggering our cars up. This is saving the planet gone mad. It will get worse. Sue their asses. Start with whoever sold the fuel and watch it go up the ladder

Greenergy is an independent oil company which was founded in 1992 and has a turnover of £775 million. They don't put green s**t in your fuel, just bio-ethanol which is becoming common practice in a number of countries. But that is not the problem, here. It is becoming apparent that the contamination is due to excessive silicon compounds (used for anti-frothing) somehow entering the supply chain. Someone, somewhere made a mistake. A bit expensive (understatement of the year), but unlikely to be malicious - and certainly has naff all to do with "TONE" (though almost everything else does  ).

[crowman]

Thanks for your knowledge about Greenergy. The point was, if any fuel supplier changes the formula of their fuel that we "unknowingly" fill up with, then they are liable for any damage to our vehicles. Would you please explain why ETHANOL is added without Mr & Mrs Joe Soaps knowledge. If it's that bloody good they should be shouting it from the tree tops and advertising it at the pumps. Have not heard a great fanfare about it. Unusual for "TONE". It is part of his legacy. Not to mention RED KEN. Ooooops Sorry. Did'nt mean to mention that.

Is it true, that this bio-ethanol in the fuel, reduces the economy and combustability of the petrol? Hence a reduction in MPG?

As such, can anyone confirm a reputable supplier where I can buy fuel, that's NOT contaminated with this green s**t

Calor, Flogas

Shell & BP, Esso USED to be good currently I do not know.
