Due to the fires here i had to evacuate my place. during the time i had stop and i had to use 87 fuel. Sorry i had expenses that came up real fast I E hotel 3 kids etc... Anyways i use chevron 91 octance but since i used the 87exon. Its hard to start in anycase. I thought it was the battery but all is good could the 87 fuel hurt my car.since then i use chevron 91 only should i try injector cleaner or anything. Sorry for the Noob question but it takes like 2 or 3 turn to get going but the starter also sounds like it has a hard time to get the engine going any ideas please

Exxon gas sucks.
I filled up with that junk a few times last year because I had some free
gift cards, and I still don't think the car runs the same.
Brought it to the dealer at the time and they said "bad gas."
Tried dropping fuel injector cleaner fluid into the gas tank -- that didn't
seem to help much. The car still has a slight 'ping.'
Perhaps a fuel injector flush at the dealer would help.
And this was Exxon 91 or 92 octane (whatever their highest is).
BMW recommends using the following gasolines:
Chevron
Shell
And others...

I've read quite a few threads on the subject. Take this, as you would anything else posted on the net, with a grain of salt.
From what i've read, it would seem that refineries sometimes trade the two lower grade octane fuels (low and mid grade) depending on what's available at the time the tankers show up. Meaning, you're buying 87 Shell but getting 87 Chevron or vice versa. Low and mid grade fuels are refined and processed in much greater quantities than high octane "premium" additive rich fuels. So you get what being processed. Exxon, Chevron, Shell, BP allegedly all do it. The only time you're sure you're actually getting Chevron with Techron or Shell V-Power is when you fill up with Premium.
Something else to chew on, using fuel with a lower octane than your car was designed to use won't necessarily harm your car but it's false economy. The OBD computer will retard the timing and/or richen up the mixture to insure you don't ping your way to new rings and pistons. However, your car also isn't running in it's most efficient state of tune. You're actually using more gas less efficiently. If you check your MPG or a few tanks of cheap gas you'll probably notice it's dropped, all things being equal.
Get your self a bottle of Techron fuel treatment and use the fuel (octane) for which your car was designed.

The Peake tool is a good tool. I have used it numerous times on my cars. A couple of tips:
1. It will tell you what the code means, it will not tell you what parts actually need replacing. You still need to have a knowledge of cars/repairs to figure out what to replace after reading the code. The Bentley Manual is a good resource.
2. Verify that your year/model is supported, I think you are OK. Starting in 2004, compatibility drops off quickly. It will not work on my 2004 330cic. They said they are working on a new unit for 2004+ models.
