VQT, welcome to las vegas, dude! I am used to the price already, so as long as it is under $2.00, I am happy!

 

I use premium fuel as suggested but am always tempted to move to the midgrade. What do you use? Any impact on performance, longevity, mileage per gallon? Anty specific brands that you prefer?

 

I tend to use Mobil Premium these days. More as a station choice since the local Shell and Speedway allows smokers in their stores and it really irritates me to walk inside to pay with cigarette smoke floating all over the place. Usually pick up a coffee and hate the smell of the tobacco on the cups when I used to use those stations. Still pay cash for fuel everyday but am tempted to try that quickpass key fob that Mobil has now. I've used midrange before in my other "premium-required" autos with no specific impacts but I don't push performance hard with my LS.

Now, I'll be buying a weekend sports car in the near future, son is really pushing Dad to get a C6 Vette, so maybe fuel preference will more important then.

 

you can always put in regular gas if you want. the computer will just retard itself to avoid any potential pinging when you run the car

but the price difference are so minimal, just don't do it

 

since the car recommends 91 octane what is the point of these endless posts about octane?

 

Relax digital, if you don't like the thread, then don't read it and don't post on it. Make sense?? lol. Personally I use premium.

uh, but out. if you dont like what I said then dont read my posts.

 

Dude you are the most inflammatory guy on this site, and sometimes I just get bored with it.... we all do.

Try to be more positive.... you'll probably live longer lol.

 

Great question Russ. I use only premium, 91 octane here in CA but I was interested if someone used cheaper and if it hurt the car at all. I would fear pinging and damaging the valves in the long run, but what I DON'T know about cars will fill many books.

Hey, the map upgrade worked for me but I was unable to copy as the dual layer DVD copier are not up to speed yet. Won't be long before I can try again once consumer hardware is improved for the dual layer copy machines.

And I agree diesel11, what has that guy got stuck in his rear? Smile, be happy!

Wow, thats how it used to be like over here about a million years ago. Im so glad i dont have to put up with smokers in any indoor enviroment.

 

91 on all my cars since 1998!!

 

hey dude,
did u notice any diff for the car performance after pumping diff grade of gas?

 

I actually moved from an 04 530 (which was a lease) to my LS430. I put premium on my LS, but always ran regular on the BMW. The car hauled @ss either way. Did not notice loss of performance.

 

Always put premium on my LS.

Station of choice is Mobil ... if I cant find any mobil, then I'll go for Sunoco or Shell. I never fill up at any other 'less' name brand stations...
