Can you tell me, is it ok to add Octane Booster to your fuel when your in a State that does not have 93 Octane. Neb, OK. Would anyone advise which one to use if you do add it. I have a 2015 Z51. Thanks

 

91 octane is fine for the stock tune, or an aftermarket tune designed for it.

 

If in the aftermarket tune & it starts to pull timing out with any knocking. To the OP here on a stock vette the 91 will work fine but would still look at adding if I was knowing to go to the track are be running the car for some long runs at WOT.

www.tuff.com SALES Kemco octane boost can go as high as 130 octane. 6x 32 oz cans is 128.00 with free shipping.

 

Both correct. Iirc, it evens makes mention of such in the o/m under the fuel requirement section.

 

Ok and Neb only have 89 octane. 2 places I race at. I do use racing fuel when at Hallet but it's 12.50 a gallon.

 

I've purchased 91 numerous times in Oklahoma.

 

Octane booster should only be used infrequently and sparingly. Any product that actually boosts octane enough to matter will, over time, kill your cats.

Same thing as meth will do to the cats.

 

Don't use octane booster. Ever. It's a snake oil product and the risk certainly outweighs the reward. That said, OK and NE both offer 91 Octane. I know this because I just traveled through both of those states recently.

 

I would use Torco. One can of torco raises octane 3-5 points. It's about $25 a can. I run it in the summer months just for added protection.

 

I have not used it in my C6 or C7 but I know a CF member Jbsblownc5 who used Torco with meth very effectively in his C6 at the track.

 

Cats... What cats? No cats here. Meth yes. Not too worried about cats!

 

Torco works good. I used to use it sometimes if I couldn't get race gas years ago.

 

tried torco and a completive product called race gas from some company in Minnesota, both in the $25 dollar range. So here's how it went, ran several 40 to 100 mph with the on board timer @ 6.3 sec.
We have a gas station that sells 100 octane race gas so 5 gallons was added to tank which should calculate at around 93 octane. Found gas mileage dropped 4 mpg for openers and did the test with no change in time. Drove it 70 miles and gas mileage came back up 27 mpg and tried the same test which by the way is a stretch along the shore to Coronado Ca, at see level and exact some temps and humidity. Car ran that test at 5.8 sec and repeated several times. Tried both the Torco and Race Gas and gas mileage dropped 4mpg but this never recovered even after driving 200miles. Ran the test anyway and all were between 6.2 sec to 6.4 sec. Bottom line snake oil and total waste of money. 100 octane race gas works end of story. I know the torco guys go nuts when I publish this but those are the numbers. My 2002 C5 lost 18rwhp after torco and 100 mile drive. By the way the gas mileage never improved for the entire tank. recently did a cross country trip with the C7 and found every time we filled with a different octane gas mileage dropped 3 to 4 mpg until around 70 miles and came back up. When I confronted the seller he said works great for him on their dyno tests in that it didn't pull timing. I mentioned maybe rather than focus on pulling timing one might say runs better with correct timing pulled or not. One other thing the Race gas guys said I needed to use two quarts instead of just one, not. Ok one more thing my new Z06 runs exacting the same time with 91octane or with 5 gallons of race gas added, what make it come alive is temp in the 60 F and lower range instead of 40 to 100 @ 4.6sec it runs 4.3 sec with low temp.

 

Junk

 

Thanks Guys I think I will just pass and not use any booster at all an as soon as I am back to a 93 Octane just fill it up ASAP. Thanks again.

 

I found this with a search.

Try this formula.
1. (Octane of fuel #1) X (# of gallons of fuel #1) = X
2. (Octane of fuel #2) X (# of gallons of fuel #2) = Y
3. X + Y = Z
4. Dividing Z by the total number of gallons of both fuels gives you your total octane number.

For example, let's say you have 10 gallons of 93 octane, and 5 gallons of 112 octane race gas.

1. 93 X 10 = 930
2. 112 X 5 = 560
3. 930 + 560 = 1490
4. 1490 / 15 = 99.33

So, the total octane of the mixture would be just over 99.

 

I disagree, most of your posts are informative and on the mark. The information you posted is not what I have seen recording the times for the 1/4 mile performance challenge on the tech section of the C6 generation.

There is one member JBS BlownC5 who utilized tarco and a splash of meth as chemical intercooler on his Z51 M6. Over the years I have found the A4/A6 to be faster than the M6 in drag racing.

If you look at his 1/4 mile numbers and compare them to another member Theofel back in 08 and 09 you would see that he was very competitive with the automatic car which was not a Z51 and had a weight advantage.

If I take similar runs: in the thread
JBSblownC5 11.25 @ 125.07 Approximate Da 07 on 02/08/09
Theofel 11.25 @ 121.01 Approximate Da 212 on 11/22/08

If I correct JBSblownC5's run for the lower density altitude the corrected time is 11.285 @ 124.59. Theofel's corrected time would be 11.253 @ 120.95. Apparently, it worked as the M6 always has a disadvantage, the above mentioned numbers were taken from actual time slips, recorded in the thread.

As I previously stated that I do not use the stuff but it apparently works as a chemical intercooler and does increase performance....if you know how to utilize it as JbsblownC5 did in 08 - 09.

You can not just pour a can in the tank and expect a material improvement in performance. Just as with any modification you have to fine tune its usage. In regard to dyno results I have seen cars dyno crazy numbers and do nothing at the track and visa versa.

 

Its my understanding that the difference in octane is due to the elevation of the area because of the atmospheric pressure. Higher elevations not needing the higher octane. So would it be benificial to use a higher octane at higher elevation without tuning for it? Would this make the car run richer or leaner?

 

Octane has no impact on how rich or lean the engine runs.
