E46 M3- V power vs regular unleaded

[Crusoe]

Always use v power in mine unless the local place runs out, get a few more mpg and feels a bit more eager. Saving on mpg offsets the price but the service indicator also goes by fuel usage so my service interval works out around 16500 miles. Change the oil every year though as I don't like to leave it for as long as that.

My M get ordinary unleaded. Makes bugger all difference on my 7mile commute of solid traffic in the morning. I run Super in the Clio, but thats the only car i've owned when i've felt it make a difference. (Not to performance, but moveover for smoothness)

I promise you, with couple of tanks of 99Ron, your Zed will feel much perkier and a good bit quicker.

And if it's an E46 M3 it will almost eliminate the kangaroo effect. (Shell99 that is, not Tesco99)

Well I imagine the majority of the E34 section in the M5 board will disagree with you

Two respected specialists - one a BMW M Master tech, confirmed the same: the E34 can be run on boggo 95, with 97 Ron having no positive effect whatsoever.

Given that I drove approx 20k miles in three E34 M5's, I would hope that I might have been able to detect a difference also non?

Given that my S14 was the S38 sans 2 cylinders I will continue to disagree... Is that the same BMW M Master tech who told me that the crunchy shift from 2nd to 3d was a characteristic of all Getrag boxes in the Z4MC... The Z4MC has a ZF box - the Getrag does not fit... Or the same people from the M5 board who said that the CSL was quicker at the Ring because of its stiffer wheels?

Of course you can run an E34 M5 on 95... Hell, I run my M3 through Serbia on 91 once as I run out of juice on the way to Hungary and they had no other fuel available many moons ago... It would not rev beyond 4500rpm though...

What is the kangaroo effect?

Sport button on, you press the accelerator to set off, car jerks, foot comes of the pedal, then on, then off and you kangaroo across the junction/up the road, very embarrassing...
