Supermarket Fuel
 

Just a little something to show how 5hite normal 95 unleaded from supermarkets can be.
I have a decat but without a MIL eliminator kit and I used to use mainly 95 ron fuel and after a little while the MIL light would come on as I expected it to. Now, for the last 2 months I have used nothing but V-Power or Tesco Momentum and the MIL light has not come on at all but on Friday I was about to set off to go to Bath and I pulled into Tesco but they had run out of Momentum. I had next to nowt left in my tank and needed to fill up so I used the 95 unleaded and I only got about 15 mile down the road and.....................................

MIL light flashes up!!!

I highly doubt this is a coincidence and just goes to show how much better/cleaner the 99 stuff really is. I will always use this now whenever possible :)

It's not all supermarkets fuel its only the bloody Tesco stuff I use and have used Asda fuel since I got my mk2 180 and have had no problems in that period. however I used normal Tesco petrol three times over that period and on every occasion the MIL has came on for a failure with the same oxygen sensor.it can't be a coincidence.

As mentioned probably countless times the only main difference in the fuels is the additives that are contained in them. That is what gives it the Octane rating, If you are running low again maybe stick a tenner in and then go straight to a shell or another tesco for Momentum. :)

I had a massive argument wit a guy on .org about this and Luke is spot on the mark the guy on .org said it was just petrol made on the cheap when it's not it's the additives that lack. But me myself háček used regular unleaded from tesco all of my driving life and never had a problem, the only thing that I find is that it doesn't last as long

Thing is I worked for Tesco (fuels) for 7 Years and now I work for Shell so i should know my stuff lol. In reference to that .org dude andy he pm'd me...LOL. In a 180 i would always use Vpower or Momentum. A 110/120 Id look more towards BP ultimate (97 Ron) or Shell Fuelsave (cheaper but fairly similar)

I have been keeping records at http://www.fuelly.com/driver/talkingcars/zs for the best part of a year and have seen no difference in consumption between regular and super from either Sainsburys or BP and despite wishful thinking no difference in performance or manners so am sticking to sainsburys 95 ron (and necter points) in my ZS.

BP ultimate is only 97, hence why there might not have been much of a difference

I put Ultimate in on the way back and there doesn't seem much difference. I have found that V-Power seems to have a bit more of a punch, Momentum lasts longer and Jury is still out on the Ultimate.

By the way, I don't have a problem with the normal Tesco stuff, I have used it for years. I was just saying that the 99 stuff obviously (with the additives) seems to burn cleaner, hence why the MIL stays off when using these but comes back with the 95 stuff. I get points with Tesco and do a 56 mile round trip to work so I will stick with them probably using their Momentum. I didn't want to turn this into a which is better thread as that's been done to death lol :) I was just commenting on how the 99 stuff apears to burn better, and my average MPG aint bad either if you look at my sig.

99 ftw ;)

I found my camaro ran rather poorly on low octane fuel
But I have never noticed the difference with the zs
