and that kind of logic, my friend, is why the price of fuel in general, and taxes, are going to keep creeping up and up, cent by cent, for no other reason than they can and guys like you say whats the difference, it's only $3 per tank. Or so what, my taxes are only going to increase by $100 a year - no big deal.
Sorry, one of my pet peeves. I digress. yes because this attitude towards the difference is the direct result to the reasons for crude oil technology going up and therefore oil refinery prices going up and the end consumer paying more lol |
I don't agree that the counter measures will not affect the life of the car, but then if i really thought the 3 points in octane mattered..I would mix in some 100LL from he airport.

Let's see, long term effects of using lower grade gas? How about not having engine repairs covered even if you are under warranty. The owners manual does not say "91 or Premium octeane recommended" it says "required", which to me means using lower octane fuel can give the dealer a reason not to cover a repair even if the warranty is still active. Other than that? You're good :twoup: I use the highest octane available, which for me (SoCal) is 91.

i hear your mileage is reduced i'll report back this could save you 30 cents a gallon Ethanol 33.1 MJ/kg Gasoline 46.4 MJ/kg |
So my mother lives in the Bahamas, and she just got a CPO 2006 750i, and in the Bahamas, the only type of gas you can buy is 87 octane and her car runs fine. she just got her car about a year ago, loves it and has no problems burning the 87, lets give it a few more years though. Car was a real gem, 2006 with only 7,800 miles, thing was brand new, picked it up for $35,500 in Orlando.

Actually, what the manual says is 91 octane is "highly recommended. However, you may also use gasoline with less AKI. The minimum AKI rating is 87." So clearly, using 87 octane will not void your warranty. And the notion that a car manufacturer can void you warranty or refuse to cover repairs is way overblown. They may try often, but the laws (especially in states like California) are set up to protect consumers. Like insurance companies, manufacturers count on the fact that consumers do not have the persistence or resources to follow through on these things.
Fuel specifications The engine uses lead-free gasoline only. Required fuel Premium Unleaded Gasoline The minimum octane rating is 91. If you use gasoline with this minimum octane rating, the engine may produce knocking sounds when starting at high outside temperatures. This has no affect on the engine life. Minimum octane rating corresponds to the Anti Knock Index AKI and is determined according to the so-called (R+M)/2 method. Do not use leaded gasoline, as |
EFF it - throw some leaded gas in that biotch and see what happens!

It'll be fine on the engine but it would throughly screw up the o2 (lambda) sensor and catalytic converter.

lower octane will not harm your car. you or your car probably couldnt tell the difference, unless the temperature is high and you load the engine a lot.
lots of times if i know i'm just going to be doing a lot of highway driving, i'll just use the cheaper gas. higher octane gas while just cruising, has no benefits. higher octane gas just prevents pre-ingition under heavier loads and higher temps. |
