well perhaps my use of the word "garbage" was harsh, I sometimes get lazy and use the easy route and dont think of good word usage. No i've never used it, but I've looked at plently of engines this guy has in his shop with crater face pistons from running Torco. Tuning could be an issue, who knows, they're not my motors.

 

Buffman,

For the record, I did not mean to take a shot at you. I am no expert on racing gas, but I buy mine 55 gallons at a time and have found that each product has a "sweet spot".

Good Luck,

Daren

 

Another good reason to run Torco.

This is Dale Creasy Jr. signing autographs for disabled kids at Rockingham last weekend. He also gave them all their pick of T-shirts from the Torco trailer.

(Dale is the 2006 IHRA Fuel Funny Car World Champion. He is sponsored by Torco.)

 

My old 1998 Camaro LT1 on Torco at rockingham last week.

The station that I use has 87, 89, & 93. Unless I'm going to the track or planning to do some hard driving, I usually get the 89. I can tell absolutely no difference in how the car runs. The best performance will come from the lowest octane that does not allow detonation.

 

I ran 89 and dynoed my car and it had a rough dyno graph. Put the 92 or 93 in and it was all cleared up. Never went back from the high grade ever since.

 

Well that Engine Builder doesn't know what craters in Pistons are..
That's from Detonation, or running really lean and hot. The higher Octane actually makes an Engine run cooler. It works, as bogus as that sounds, cause the Higher-Octane burns better, cleaner, and the Engine can control the burn of it faster for Timing adjustments.

 

I would say are the one without a clue. If the engine builder has a problem with cratered pistons with one fuel then he realizes it is detonation.

Higher octane resists detonation better, some race fuels burn differently and whatnot but that is not the point. Octane is ONLY a measure of detonation resistance nothing more, some higher octane fuels actually offer slightly LESS energy but can still help build more power IF the compression and timing are setup to take advantage of it.

As Hondahunter said you are going to get a lot of misinformation much more than good info. If the car and PROGRAMMING are stock then the recommended 91 is all you need, more is NOT better. If the programming is setup you might see a slight gain with 93 but that would be from the programming not the octane the octane would just support the programming. The ignorant here will call BS but if the tuning is setup for it you could run 87 octane without issue. The LT1 b-bodies do the compression is slightly lower at 10:1 instead of 10.4 BUT it has iron heads and most agree aluminum allows as much as one full point more compression before detonation is an issue.
A lot of us that modify our engines be it heads and cam or a full build go to 11-12:1 the engines run great on 93 so no way in hell does a stocker at just 10.4 need 93 unless the tuning is aggressive and again that is tuning requiring it NOT the hardware as the ignorant here will lead you to believe.

There was a big pissing match on this a month or so ago a few stupid kids on here kept arguing with me sighting such direct edidence as "problems down the road" and other such wisdom . Do a search and read through my replies there and see what you think.

 

When I first aquired my Camaro, i didnt know anything about octane.

I ran 87 for almost a year, then found out from and old friend that 91 was t3h ****. So put that in and immediatly felt a difference.

Like 96capricemgr said its in the program/tune. Really the lower the octane you can run without detonation the more performance gain. Remember simply put Higher the rating slower the burn.

 

I was waiting for that ****** to say something in the LT4 Threads.. must be he figured he can give 1 of us **** somewhere else, but not the bunch of us.

 

As I told you in reply to the nasty PM you sent me I refuse to let bad info just slide and you are full of it.

You had a week and a half to spread your stupidity while I was on vacation but I am back now

 

ooooo... He's back.
We are all stupid guys, this is the GM TECH right here..

 

Dude,

Shut the hell up. Talk your "****" in PMs.

Tony.

 

That guy is a terd, not my fault. He needs to learn some people skills. If someone had some wrong info about something, I would be like check this out real quick, or look at this, instead of telling them how much of an idiot they are for putting in an input.
I'm sorry I am not the best cause I have a life and an excellent job, other things to occupy my time when I am not working with the car.

 

Its cool. I understand that people have different sides of the story/topic.

Everybody always has something to say, you just have to ignore it sometimes.

Tony.

 

Mine runs the same on all Octanes, but that could mean something is a bit wonky somewhere else. I haven't had my car long enough to dump in a few gallons of 110 to see how it behaves. Seeing as it's $4.50 now instead of $3.50

 

Opinions are like ********, everyone had one and they all stink.
Gas has been going down, so that is a good thing.

 

True, everynight on my way home from work i check the same station. In 4 days its dropped .13 cents. Sweet!

Tony.

 

And I have to break in my new Engine. Best time to drive alot with cheap gas, now I have a reason.
