Just to let everybody know, I have been putting in 89 octane (mid grade) gas in my car ever since I got it and its been great. No knocking and it still hauls *** in the upper rpm's. Just a little FYI for everybody...

 

thx

 

I have not tried using regular 87 octane yet, nor have I tried premium. I guess I can be the "guinea pig" so to speak, but I can feel comfortable telling you guys that 89 octane gas is safe if you have the RRM piggyback ecu.

 

good to know...but 10 extra cents just doesnt bother...but it is good to know.

 

10 cents a gallon makes a difference when you go through 3 tanks of gas a week, like I do.

 

wow u drive alot...i mean i drive everyday and all but i can go like a tank a week.

 

Agreed brotha! Dude gas here in Cali is at $3.05 for premium, about 2.90 for mid and around 2.80 for reg. Its so rediculous. I mean i could get it for like 2.60 at ampm but i wont put that crap in my car. Its either shell or chevron for me.

 

It's only $2.35 or so for regular around here, but I'm still putting in around $80/week in gas.

 

here in stillwater MN its $2.19, where in WI are you btw?

 

Racine County, so we get the same gas as Milwaukee and Chicago, rather than the regular stuff that the rest of the state (and most of the country) gets.

 

i go through 2 tanks a week and tha sucks monkey *****. i orderd my hood scoop!!! so i might bet he first the do a scoop on the ralliart. and im making it into a custom short ram cold air intake thingamajiggy!!!! ill post up as progress continues.

 

Went totally off topic, but I will keep you all informed when and if I recognize any difference if i put in premium over mid grade.

 

Ok heres my update. Ive been running 93 with the piggyback, and I havent recognized a thing. Seriously, not a thing. Ive been running 93 the past few times ive filled up and felt no difference at all. So the conclusion here is run at least 89. Premium wont do you a bit of good. I think I will just stick with 89 to be on the safe side. Even though im pretty sure 87 wont do much harm.

 

After making this statement... if something happens to a persons motor will you warranty or repair the issue? If not i would not make those statements.

It appears safe for you... but someone in colder climate, lower altitude, etc... may have a problem running the lighter. They may not know what pinging sounds like and keep driving. Then when the motor fails they'll say RRM sucks but RRM never stated what you have.

Think you need to edit your statement on this and keep us posted on your pioneerinig efforts.

 

I'm pretty sure Rock agreed a while back that 89 was pretty safe to run with the piggyback(not positive on this). As in all things it's still at the users risk if they run a lower grade gas.
