Good news for Shell, maybe they'll cut prices

If you have near you a Tesco stocking 99RON it's a no-brainer really.

 

Until Shell publish the spec of their Optimax 'wonderfuel' I'll be sceptical of any marketing claims.

 

I'd also go for the 99RON even if it were *more* expensive, which thankfully it isn't. Far from that.

 

Not prepared to take any chances under boost.

Oh doo shut up about it, EVO have done test after test and their are loads of much higher powered cars than yours running it just fine. It works, it cleans well. Evo got good power from Tesco 99 so recommended a 3:1 ratio of fill ups between tesco's and optimax because the Tesco's fuel was very advanced on the cleaning side of things. But they also said just use what works for you.

 

Shell is not the devil and your personal hatred of them seems to cloud any objectivity.

Sorry but it's not keyboard warrioring it's just everytime Shell is mentioned John gets on his soapbox about Optimax. Sometimes I have to vent, and yes I'm particularly stressed at work right now :)

 

Also Ian's not in to rein in my enthusiasm/pull his weight! ;) :p

What i wanna know is when will we be getting Optimax Extreme?? :clap: 100ron petrol :D

Now that would be a move in the right direction.

As long as they market it as 100RON and not rely on rumours and innuendo.

 

Here is the specification of the Tesco fuel.

Clearly 99RON/87MON

 

Until Shell publish their own spec for Optimax, there will always be a cloud over the issue. Ads with Ferrari pictures and fish swimming faster just don't cut it with me. Sorry.

Not sure about the 5% ethanol, that stuff evaporates fast.

MPG will get worse as well, because the calorific value of ethanol is lower - so is the stoich AFR.

 

I'd prefer the 100RON to be there because of distillation, then add whatever I want to add in the juice. That way I can only add 'spices' during high boost operation, what's the point during idle/off-boost?
