100 OCTANE in San Diego?
 

anyone know of those 76's that sell 100 octane at the pump

its for my e63. lol recommended octane is 98, min is 93 :((((((((

and in cali the typical highest is 91 lol!

Yeah...

The 98 octane you are reading about is the RON number, used in Europe. It is roughly equivalent to 91 octane by US standards.

You are fine running 91 octane, but 93 is preferred.

-m

No more of the 76 stations here seem to have it, but I do know of 3 stations that carry VP Racing pumped. 2 are in PB and 1 in Rancho santa fe. Let me know if you need more info.

tell me about the one in PB please? intersection?

and thanks marcus, i didn't know that. its not bad to run it on a full tank of 100 once in a while is it?

It is on Ingraham Street heading south BEFORE you get on the bridge to Mission Beach. The Pumps all have VP Racing labels on them. It used to be a Chevron about 3 years ago.

where is the one in rancho santa fe?

Or if u head east, there's one right off the 8 and mollison. 100 octane!

Straight up at the down town area. Very posh but $7 a gallon is up there anyways...

Its right in the village,

Its the same gas station that Mark shaw from wax on wax off does his detailing from.

You can get tuned for E85, not sure if that is an option for you or not but it has a motor octane rating of 105 and is roughly $2.69 per gallon. 91 will suffice though, no need to go higher unless you are looking for bigger numbers.

Is there any performance benefit of running over 100 octane on a stock car? I have a a station by my house with 110 octane?

Not without a tune.

Thx to both you and "infantry" for posting this up...:y

I have been using 91 oct Chevron since coming into "town" and have been having a weird idle and off idle stumble. :crazy:

I topped off the tank with VP 100 oct Saturday from the station in PB and after about a half day or so of driving the response and idle has much improved.

I have been searching for pump supplied 100 oct, and didn't want to buy a 55 gal drum from a supplier (let alone, no where to store it).

Any way :bow: for the heads up

Is this something you noticed when you hit Cali? We run nitrogenated (good for environment) gas here and I think a disadvantage is octane. That is why I heard we get 91 here while most places get 93.

Anyhow, just curious because the 55k is notorious for the "stumble" you speak of. Most Benzes are but that low end TQ just shows it. If running higher octane on a base tune helps that, then this may be a hint that can be used for tuning. I know everyone always says that running octane higher than the tune requires is useless or even harming (for performance) but I have always had the opposite butt dyno effect.

Marcus, the situation is actually slightly different for the 63 engine. Unlike the minimum octane rating for all other Mercedes engines of 91, the 63 does require a minimum of 93 octane (US ratings). I had a few conversations with Mercedes/AMG about this and although they told me that it was okay for California cars to use 91 octane, they said that I would lose a little bit of performance due to the ECU limiting power in order to adjust for the lower grade fuel, and that it would not void the warranty since it was/is the only gas available here in California.

From my experience, the 63s like it most when the rating is around 95 octane; too much lower or too much higher did not produce as good of results.

Funny marketing for AMG to put 93 requirements on a motor eventhough 25% of them will never see better than 91.

I agree with you that the added octane helps to a degree. I have also wondered about the additives that are in my 91 that I use. Is it really 91? IMO Cali gas SUCKS!

Anyway to make a point, I wouldn't really feel to threatened to take a car in that had blown by running lean ;)

Hmm...there is a station right down the street from me with 100 octane. I've mentioned it before. I need to fill up the E63 soon. Maybe I'll spring for the $8.00/gallon and see if I notice a difference! :p:

You will. It will help just by flushing your system......tell us about the butt dyno ;)

If your ECU is stock you'll probably won't notice much of a difference. Maybe a 1hp increase at the most. lol :rolf: :p:
