What Percent Ethanol is good For the e60?....the lower the better or the higher the better....i'm sorry if it sounds like a dumb question...i just wanna put the best in my baby


EDIT: Sorry i WAS talking ABOUT OCTANE LVL...i asked the gas station guy about the ethanol lvl...wrong thing sorry!..

 

atleast 91 octane. dont go any lower. 87=bad, 89=bad, 91+=good

 

DONT PUT PURE ETHANOL IN YOUR CAR

i assume you are asking about octane. use 93. why not. you drive a bmw. dont like the 10-20 cent price difference per gallon? drive a 86 chrysler lebaron.

i am sure this thread will be full of people debating cost/benefit, octane levels, particular gas stations. just use premium. why not?

 

yes ofcourse...i will be using premium only...if u can afford a bmw...u can afford premium..

 

When gas price was $4 over, I mix 3/4 tank of 93 & 1/4 tank of 87.

Pretty much when you are @ 3/4 tank, fill up full w/ 87 then next fill up back full tank of 93 until you are down to 3/4 of tank then fill up full 87 and etc etc.

Right now I use 93 w/ Techron

91 is the lowest octane for 545 w/ max of 10% ethanol blend.

 

$4 a gallon would be great try over ?1 per litre

 

Check this out, a guy in my local car club has a turbo m3, he runs methonol in it. Check out the dyno.


Rode in his car last week, its a beast

 

BMW recommends 91 octane.... The less ethanol the better, although I think now 10% ethanol is pretty much everywhere by law. BMW has stated (in my manual) that ethanol content of 10% and below will not void the warranty (Implying that above 10% it may void the warranty), so be sure to put only quality brands of fuel in the car as you will be less likely to get a blend with nore than 10% that way.

Engine will operate OK on octane levels down to 87, but will not give the best mileage or performance on the lower octanes. You will not damage your engine by using octane levels between 87 and 91.

These are the recommendations for my e60. You should check your owner's manual for your model.

 

I just read that methanol was bad for direct-injection engines. How is he doing this?

 

It's about ?4 per gallon or $6. Don't know what's the average wage in US is at but in the UK ?1 per litter is just not nice..
