Hello,
When I go to Autzone they have lots of gasoline additives, Some promising cleaning, others more octane others more mpgs.

Do any of them actualy work? Is there an additive to help reduce KR?

Just wondering.

 

Octane boosters from what I've heard don't do nearly as much as they claim. I think I read somewhere that people who were seeing knock because of fuel were adding a little bit of toluene to their tank. It's used usually as a paint thinner and can be found at places like Lowe's

 

Most of them are BS.

 

only thing i use is Lucas injector cleaner

 

^same here

 

If you have wideband...add E85 to get rid of KR

 

Just not too much or you will be running too lean for your fuel mixture

 

HEET is methanol. It'll raise your octane rating / resistance to detonation. Buying higher octane rating at the pump is cheaper.

 

Exactly. When im around the 1/16th of a tank i know i can get 10 gallons + 1.5 of E85. AFR usually stays around 12.0-12.5. Tuned for 11.7

 

If you've got e85 available, why not get tuned for it? Can't be because you are afraid of blowing up your motor

 

Well when it was warm out i didnt have enough money and now that i kinda do the mix is E70 and its cold out.

So waiting till spring. Ill definitely be switching

How much timing do you get running meth on the 2.8?

 

Was running 26* for awhile but either changing to winter blend fuel or something was giving me a little knock so it's lowered to 18* to be safe for now. Plus my damn lightweight flywheel doesn't absorb vibrations and it shows up as false kr

 

Holy **** thats a lot. Im on 14* and get KR from winter blend gas. Mix E85 and it goes away

Cant wait for E85 so I can get more timing

 

When I get wheel spin (which is frequently in the cold lol) I sometimes see a tiny bit but it's just false kr because no wheel spin, no kr

 

Mine pops up with 3*

 

Winter fuel ruins everything
