LT fuel requirement

I am going to be ordering in the next few days and I forgot to check when I was looking, but what is the minimum octane requirement for the V6?
Thanks!
Johnny

Regular. I think 87 or whatever the number is.

The V6 should run on 87 octane.

Minimum is 87, runs fine with a little bit of "knocking / ping".

I use 90 octane fuel in my 1LT, I can feel the power now !

i was told that using a higher octane than recommended will dirty your engine. any insight?

It shouldn't knock or ping on 87. When I had my '93 Camaro V6, it was programmed to run on 87 and I got a ping on hard acceleration. Took it to the dealer and they reprogrammed the PCM (I think) and problem solved.

no. in some cases it can be a slight waste of money if the computer isnt programed to make use of the higher octane fuel. but the v6 req 87. if you want to run premium, it wont dirty or harm the motor at all

unfortunately the dashhawk isn't able to log thing like the knock sensors or if the computer is pulling timing... BTW, the motor will actually hear the ping before you do... I may have to try playing with it again and go through the item more carefully to see if I can find something useful to monitor...

Thanks again everyone, I just wanted to know what is required so I can estimate my fuel costs. I'm sure I'll put premium in once in a while, just not every time.

I asked the question because it's 11:1, and compression is usually the main factor, but from the little I've learned, it seems the DI helps it to better avoid detonation. I'm guessing this is because it can inject the fuel later during the compression stroke.

87 or 89 will be fine. anything more will be a waste of money in a 6cyl Camaro due to its timing setup.

I'm at 1,600 mies total and 1,300 miles on 89 - it took 2 tanks to feel the difference from whatever 87 the Dealer put in on delivery. Now it sounds so much better on start-up and idle, and seems like it enjoys the slightly higher octane level on passing or merging.

So for me I'm sticking with 89, preferably from Sunoco.

not necessarily... still a lot of unknowns with the Bosch computer... Some cars like the Mustangs will automatically try to add a bit a timing... The Camaro in theory might be doing the same thing... just don't know... yet... LOL

the computer will continue to add timing until it starts pinging. at which point it will pull back and start over. almost every EFI car out there does this. part of the reason you can run 87 in the SS as well as run 93

The factory design specs on the car were mapped for 87 mexico piss rated fuel. Their engineers already state there are no more "aggressive" maps for higher octane fuels.

As CamaroSpike pointed it, it could simply be adding a bit of timing..... I was monitoring a PID called "Spark Retard"... it was definitely changing.... going from 0 to 4.... now was it adding or pulling timing I'm not sure... need to dig in a bit more... unfortunately the Knock Sensor PIDS are not working... But that's how the Mustangs work... they will add timing until the car pings and then back off the timing a bit... I just need to figure out the value range for Spark Retard and if running different octanes makes a difference...

lol Mexico piss fuel. Actually the oil Mexico pumps is the same that we get out of the Gulf of Mexico and it's considered one of the better crudes to work with quality wise.

And Mexico does not export refined gasoline from there one Federal run gas company, PEMEX.

First off, it's a joke --guess you haven't heard the horror stories bout the dreaded Mexican piss...

It has nothing to do with the refining, rather the watered down crap that you find at little hole in the wall places all over the country (our country). The term Mexican piss just conjures the images of where these little shops might have gotten their fuel from.

The point being -- this engine will digest just about anything and still make it's SAE rated power through the wonders of modern technology. Throwing higher octane at it isn't going to change anything.

throwing higher octane may not change anything... then again it might... depends on how adaptive the computer is... I know with the Spanish Oak in the S197 Mustang the GT saw a 5RWHP gain by using premium... I don't think we have enough information on the Bosch in our cars to really know for certain if running premium will change anything... could be any change it does make is quite simply imperceivable by the driver... Again unfortunately my Dashhawk doesn't work monitoring the knock sensors..

Agreed -- however the devs for the 3.6DI fuel maps already stated the engine does not actively attempt to advance timing to check if higher grade fuel is there. I'll see if I can dig up the article... basically, they locked it down.

ICMP Echos.


But no, ping in this context is the pre-detination (knock) of fuel, which producing a "pining" sound simmilar to that of a bb bounding around in a tin can. It kinda goes back to the old days when you could audibly hear it on big carb'd V8's, where you would advance the timing all the way till the point of ping, then retard slightly.
