Can i use 100 octane gas for my 1992 audi 100-2.3e?

 

Yup, but your not going to get much from it. Make sure it's unleaded.

 

I am not hoping to get horsepower. I heared that the enhgine runs smother on higher octane level is that thru?
Also does the car switch or something, i also heard that some cars had manual switches for diffrent fuels. So i just fill it up in and that is that?

 

You have a pre ODB II car. It will not switch, or run much better. You also have a low output engine, that was made to run on 87. Chancing octane will not increase performance for you, unless you have a lot of deposits, that have raised the compression ratio, & causing some detonation. Then it will help, but even mid grade can fix that.

You are just throwing away $$ for nothing. Put some 93 in there, with some Redline SL1, or Amsoil PI cleaner, & that will give you all you can get for 1/3 the cost.

 

the lowest octane level in my country is 95 and i am courently using 95. On the tank its written 92+.The cost diffrence bettwean 95 and 100 is realy minimal. Thats why i am probably going to switch.100 octane is probably better for the engine right?

 

That changes things. You have the same octane as we do, it's just measured differently. So 100 octane is just our 93octane. Over here, if you say 100 octane, you are talking about race gas, that is usually $2-3 per gallon more.

You can put 100 in there, but it's doubtful you will see any differences.

 

OK tnx
