The New E-10 gas .. problems..

[snek]

I did the turn-the-key-on-wait-and-off before starting and the car fired right up.

[GadgetGav]

I jumped in and tried to start straight away. It fired and then stalled just like it did before. That was with 87 Mobil...

My '04 Cooper S was doing this recently after the switch to the 10% ethanol fuels. It was stalling after the first start or needing extra cranking time to get started, and occasionally would stumble/get rough at idle after running on the highway (like at an off ramp). The car was in to MINI Peabody over the past weekend for a wheel bearing replacement, and they reflashed the DME and the problems have gone away.
My MA, who took the car in for its appointment, mentioned that a lot of owners are having this trouble lately due to the fuel switch.

I hope it's a permanent fix for you, but the problem is that whenever they re-flash, all the learned stuff is erased and often, as the car re-learns, the issues all come back again

Or ... the car now learns to work on summer fuel, and then the issue recurs when we switch back to the winter formulation in late October / November

yeah.. I dunno, I think it's more than a software thing like Ian's thinkin'...

Still crappy starts for me today, but runs great.. took it ou on the highway and opened her up.. she's doing much better with the lower octane.. (so what do I do?.. I was looking for some upholstery cleaner that Pete had at the local PepBoys.. yeahhhhh.. I bought a can of this fuel stuff that has NitroMethane in it.. YEEE HAAAAAWWW!!... probably not too good for the motor.. and it's NOT street legal.. but it works.. )

I have an 06 MCS, and no problems so far with the new US E-10 blend ... I've been using the 93 octane at BP stations.

[Aqualung]

definately the same probs for me, '04 MCS/JCW....starts and dies, idle revs are low. Sometimes the trick of turning the key on to pos 2, waiting a few secs and then starting help.

I've been running Mobil 91, Sunoco 91 and Citgo 91, next tank I'm going to try 87. Then again, I'm going to MoP on Monday to get my new tires mounted, and I won't fill up by then....I'll ask there as well.

[RenaultF1]

I filled up yesterday - VPower - but we still have the old blend and no ethanol yet so no problem here. I'll post back when they finally change it in Maine.

Hmm... how long to get to the first gas station in Maine..?

We're the last to get anything here, we only just got indoor plumbing ...although, all kidding aside, they may have it further south.

08/2005 build MCS.
No issues with the new gas formula from Citgo or Shell.
Always use 93 octane.

I only have Mobil and Citgo conveniently located near me though.. the Mobil 87 has been running great though...

Remember: Different states...different fuel concoctions.

In Canada, I quite often use Mohawk or Husky mid-grade (E-10 94 Octane). I have not had any problems with cold start. In fact, my gas mileage appears to be up a bit over non-E10 91 Octane gas.

However, there is the possibility that I have a slight decrease in low-end torque as I noticed I chirp my tires more from a standing start when not using the E-10 stuff .
