 Subject: Octane...?
IP: Logged
Message:
Just wondering what octane you guys are running
in your Dakotas for what yr of truck?
I have a slight ping/ticking noise and no its
not the timing chain, I just replaced that a
few thousand ago. It almost sounds like a leak
somewhere in the exhaust and you can still
hear it ticking while accelerating.
I am currently running 87 and may switch over to
92, what you guys think?

yeah go for it also you may want to get a 180 degree t/s to help with detonation and autolite 3923s
i run 93 in my 98 3.9 and super 104+ (sometimes) and it runs like a raped ape. although my mods really like the higher octane too :-)
just my .02

Dan I will try 93 octane next time I fill up and
see if it helps any. Im still going to have to get
that torqued off K&N intake stud out of my TB...

Allthough everything you are doing will help you might want to go to ---
http://dodgeram.org/tech/gas/Trouble/ping.htm
Larry listed this website a while back and it is full of information on how to elliminate your pinging problems ; ))
The best thing you can do is really, really overdose on some good fuel system and combustion chamber cleaner to reduce a few of your predetination problems... They list plugs, radiator cap, tstat, and everything you can possibly do to elliminate your problems...

IMO I lost power when I went to 92 octane - try the 89 - it keeps the power there and helps the pinging -

Most production street vehicles, even high performance ones, are not going to benefit from anything higher than the recommended octane. So it only really becomes an issue if you are unfortunate enough to live in a state that has made unavailable the octane your engine was intended to burn (like California).
Octane rating is a measure of the fuel's resistance to pre-ignition. High-octane is specified by manufacturers when the engine requires it. High compression, high temps, or turbo engines will do better with high octane due to its slower burn rate.
Basically, the numbers you see at the pumps only indicate the anti-knock index of the fuel. It is measured using RON + MON and the divided by 2 (R+M)/2. In short, RON (Research Octane Number) measures the fuel's anti-knock index simulating light load, typical street, normal driving conditions. MON (Motor Octane Number) measures the fuel's anti-knock index simulating high-speed, high load conditions.
They used to post the RON and MON octane numbers in small print on the Sunoco pumps but I haven't noticed this lately.
Run what your owners mauual specifies. Put the high-octane in an engine designed for 87 and you have incomplete combustion ... and a waste of 20 cents per gallon.
__________________________________________________
It’s been my observation that if an engine does not require high-octane fuel, it will run cleaner and better on the fuel it was designed for.
__________________________________________________
A little FYI ... "Octane Boosters"
Most "Octane Boosters" use the phrase "up to", as in "raises" the Octane Level "up to" 10 points ... so you may only go up between 1-9 points, and maybe 10.
HERE IS THE CATCH
a point is --- (unfortunately) ... just a decimal point.
Therefore:
"10 points" brings you from 93 octane to 94
"5 points" brings you from 93 octane to 93.5
"1 point" brings you from 93 octane to 93.1
For this reason, I am not a big fan of the products except for qualifying runs and actual racing events.
That being said, if you are going ot use
an "Octane Boost", please consider Amsoil.

TOO MUCH OCTANE CAN BE BAD
Right now there is a lot of talk about the highest octane fuel that you can make (or use), especially in the "street racing" fuel business. People relate the highest octane to "my motor is making more power". That is simply not the truth.
One of the downsides to building a fuel with ultra-high octane is that the blend really slows down the flame front in the combustion process. You can get the flame front so slow, that the engine is now running in a "too-rich" condition. This actually takes away horsepower. Bottom Line --- you are slowing down the flame front and getting rid of detonation, at the expense of losing horsepower.
I hear of this all the time from my clients that "street race" --- engines running "heavy" ... and they are trying to tune it to lean it out, when actually the flame front is causing the problem.
