I put reg. in my tank once, mistakenly. Instead of using the gold pump I used the green ( not paying attention). Noticed that the car burned through the reg. faster than if I'd used premium... Didn't notice a difference in performance etc. but I never used reg. again.

 

Wow, don't come to NC...... our green pumps contain diesel!

 

OK, so my previous posting was misunderstood. No need for anybody to post a response to this post (Mods, please do not close and merge with the "other" mega thread). I just want to know how many people are using regular in the car. Hence the new poll!

Thanks for participating!

 

Hey, I mean at the end of the day the difference between regular and premium is $4.40 (only $0.20 more) to $11.00 (your $0.50 more) per tank full out of pocket. . .

 

Sigh..yet another fuel post. ...

 

lol!! you made me laugh, should we say once again, "you got to pay to play"?

 

My opinion; Premium Vehicle=Premium Gas

 

The last two paragraphs of this story by Car & Driver sums things up:

Well, no, I'm trying to collect data, not opinions............

 

Any opinions of this?

Which is better? Premium fuel with ethanol or regular gas without any ethanol. I still have a gas station about 15 minutes away that sells regular only without ethanol. I know it’s much better for my lawn equipment. But what about my cars that require premium.

 

There are tons of posts on this topic already. .have you really searched? Just sayin..its a topic beat to death

 

I would say the poll results already at 17-1 pretty much sum it up. Saving at most $11 isn't worth it. If it is, there are other vehicles.

 

I only use the best I can get. Here is 91. What are the thoughts of running e85

 

You cannot run e85!

It's very corrosive, and the car has to specifically be set up to run with this fuel, with stainless steel fuel lines, etc.

conversions are possible, but doing so aftermarket means tearing apart the entire engine/fuel system and would be looking at $10k+ for work.

 

So where would we run into a problem with the 460 fuel system? I don't see lexus using metals that aren't stainless steal in the fuel system. I know a bunch of the performance guys running it on their cars for the octane benefits. I know they aren't replacing the entire fuel system. Fuel rails are stainless. They get higher flowing fuel injectors and fuel pump.
