Mobil at Bulls today has removed E3 91 and just gone to regular 91, and E10 98 has been replaced by E10 95.

I'd be interested to hear from anyone who buys petrol from Mobil with ethanol fuel, as to whether their local station has done the same thing. I'm guessing it's a North Island wide change.

Most of the stations in Auckland have installed 98 over 95 in the last few months. I don't recall seeing any e ones though.

Most Mobil stations in Wellington haven't had 95 for many, many years.

TBH putting E fuel in your car unless your car is modern and designed for it is asking for trouble as E fuels eat away at the fuel lines and end up causing all sorts of problems.

Yes it does eat away at literally everything, Im currently running Mobile 98+ what ever it is and it runs well in my BMW. M52B28 engine, Made in 1999.
I will either use BP 98 if im feeling rich or Mobil as its a bit cheaper. Cant remember if the auckland stations sell E10 98.

 

The Mobil 98 actually holds its octane rating or what ever for a longer period of time voer BP fuel. Apparently a better fuel. Need to find the octane lost over time graph on this forum somewhere!

 

Oh ya, and Shell Todd Oil Service AKA Z is crap.

I tend to buy mobil since it's a touch cheaper. I wonder if it's hurting my 2003 Corolla, or the 2016 Nissan.

I had thought that Ethanol boosts octane rating, though with 4% less energy density, which means taking off 4% fuel efficiency?

 

So 98 with E10 is effectively made up of 95 + Ethanol...

 

Personally with my 4 pot engine I find Gull's 98 is actually the quietest for me at highway cruising speed. BP/Mobil somehow uses fuel up quite fast. Shell's 95 so not really comparable with 98 offerings?

 

It'd be good news for mobile removing Ethanol for 91s as my daily beater uses that and Mobile seems be the cheapest round where I live. good job! E10 fuel just don't last very long for some reason.

The vehicle handbook will answer that for you.

Strangely, it's sitting right next to me in my office. It doesn't mention it, but various reference websites say it's fine.

I used to have a '99 BMW E46 328i (M52TUB28) and I noticed a massive drop in power and economy when I put Mobil ethanol 98 in it over BP 98 or even standard 95, actually thought it was broken the first time I went to overtake someone and nothing happened.

I live in Auckland and have never noticed Mobil selling any E fuel at all.

 

In my Rs200 Altezza, I regularly run Gull 98 which is up to E10 I believe. I find that I get about 30 km less per tank compared to BP or Mobile 98 (that will be due to the 4% drop in calorific value spoken about above) . Gull 98 used to be a little cheaper which made it worth while despite the drop in KM, however lately the price split between 91 and 98 at Gull has been fluctuating wildly, (up to 21 cents) and their 98 is often more expensive than BP or Mobil.

 

I didn't think Ethanol attacked rubber pipe lines - ? I though it was the water it is capable of absorbing that was the potential issue (rust, misfiring, gelling of the fuel).

Ethanol is pretty bad across the board unless your a big HP turbo car.

 

It attracts water, Eats away at rubber. Burns hotter so can destroy your particle filters and or manifolds faster if your a turbo car. (A beams 2L 3s-ge pea shooter shouldnt have a problem tho)

I believe it is only the Lower North Island Mobil's that get Ethanol added
