ptjones Posted November 18, 2015 Report Share Posted November 18, 2015 (edited) After using NOS Octane Booster Racing Formula a month ago and five fillups later my HWY FE has increased 2-4 MPG. It doesn't appeared to improve City MPG much. This morning I went to the Atlanta Airport and back on I-85, about 70 miles, Temp 56*F with some light rain. Speeds were between 80mph and 60mph most of the time and averaged close to 56 MPG, then when you add in the loss of 3 mpg from outside temp of 56*F + light rain it just makes it that much more amazing. I'm wondering if the ICE computer learned to run more efficient after using NOS Octane Booster. :headscratch: It would be interesting to see if anyone else can duplicate my HWY MPG improvement by filling up with Premium and adding a bottle of NOS Octane Booster. It is available at Walmart and most Auto Parts Stores for $10-$15. :shift: :) Paul PS My HWY MPG is almost as high as CITY MPG.

SnowStorm Posted November 18, 2015 Report Share Posted November 18, 2015 Maybe it does injector/cylinder cleaning which helped MPG - not just octane boost. Anyway, I'm confused about what you used. You say "racing formula" (as in picture) but the prices I see for that are like $70. The "Max Street" version is about $10 but only has half the octane boost. Which did you use? Also wondering why the NOS site says "racing formula" is not for street use (Walmart says nothing about that restriction). It seems my mileage has dropped a bit so have been wondering about using an injector cleaner and which one is best. Quote Link to comment Share on other sites More sharing options...

I thought I got it at Walmart for around $10 about 2 months ago. ;) I'm sure injector cleaning could make a difference, but last time in used Tectron Injector Cleaner and it didn't make a difference. The nagging question is why am I getting better HWY FE for a month,than I have ever gotten, 112K mi. Total , weird! ;) Paul Quote Link to comment Share on other sites More sharing options...
10UHCSEL Posted November 18, 2015 Report Share Posted November 18, 2015 Might try any of the gas treatments available, whether STP, or Supertech, WM's brand, it may or may not help but these only cost about $2/bottle and usually treat 21 gallons per bottle. I use the Supertech brand in my vehicles during the winter time to offset the winter blend gasoline, and it reportedly cleans the injectors and such. My mpg is usually the same as my summer mpg or a bit better. I've read where winter blend gas knocks the mpg's down 10-20% Quote Link to comment Share on other sites More sharing options...

Here is a link to Octane Booster Testing: http://www.lotusmarques.com/info/technical/29-general/723-octane-boosters-do-they-really-work. Practically speaking anything cheaper than +$10 is just cleaning the injectors. I did call STP to find out about their Octane Booster and they said it had Jet Fuel in it like that was a good thing. I Laughed :lol2: . They didn't know what Jet Fuel is so I told them it is Diesel with an additive to keep the Diesel from jelling at low temperatures. :) Paul Quote Link to comment Share on other sites More sharing options...

high mileage daddy Posted November 21, 2015 Report Share Posted November 21, 2015 Thanks for the information. I think I will try the Nos racing version when I get my car back from dealer. Did you notice any smoke or smell from tail pipe or any indication of cleaning additives? ptjones 1 Quote Link to comment Share on other sites More sharing options...
obob Posted November 21, 2015 Report Share Posted November 21, 2015 I am satisfied with just regular gas, however, there does seem to be people that get the cost down with home brewing. https://www.google.com/search?q=what+is+the+main+ingredient+in+octane+booster&oq=what+is+the+primary+ingredient+in+oc&aqs=chrome.1.69i57j0l2.12219j0j7&sourceid=chrome&es_sm=93&ie=UTF-8 http://www.gnttype.org/techarea/misc/octanebooster.html http://www.clubwrx.net/forums/engine-modifications/44006-homemade-octane-booster-formulas.html http://forum.miata.net/vb/showthread.php?t=417082 Quote Link to comment Share on other sites More sharing options...

Temps were 45-55*F and the funny thing is I was improving my FE over what I had before I got on the FWY. My current average on this tank is 55.5mpg for 508mi, my fifth tank after using NOS Octane Booster. :) Paul Edited November 21, 2015 by ptjones Quote Link to comment Share on other sites More sharing options...

ptjones Posted November 30, 2015 Author Report Share Posted November 30, 2015 Thanksgiving Day I made my usual trip up I-85/I-285/I-75(70mi.) and traffic was surprisingly light with no Semi's for drafting. Also speeds were very fast 70-80 mph most of the time with a range of 60-85 mph, outside temps 68-70*F. Given these conditions I still averaged 48.9 mpg! :) Paul obob 1 Quote Link to comment Share on other sites More sharing options...

WNY Posted December 9, 2015 Report Share Posted December 9, 2015 Gonna try some of the octane booster on our trip to Chatenooga, TN in a couple weeks. That will be a good long drive test. with snow tires and center grill cover. 46psi tires. When we came back from Nashville, it avg. 46.9mpg. :) ptjones 1 Quote Link to comment Share on other sites More sharing options...
fbov Posted December 10, 2015 Report Share Posted December 10, 2015 I find it hard to judge differences on the highway. Too many confounding factors, like wind speed. When driving Rochester to Baton Rouge, and back, mileage didn't vary with temperature (it was February), it varied by direction. To BR is against the prevailing winds, coming back, the wind was at our back. I guess I'm saying, YMMV, or not. HAve fun,Frank Quote Link to comment Share on other sites More sharing options...
ptjones Posted December 10, 2015 Author Report Share Posted December 10, 2015 Here are the results from testing from testing with and without Grill Covers with temperature change. One trip going across AR about 200 miles ending up West Memphis for gas temps started at 65*F and ended up at 32*F. It was amazing to watch my gas mileage go down 6 mpg in three hours of driving and that was a 600 hundred drop in elevation and not to windy. ;) Paul Quote Link to comment Share on other sites More sharing options...
fbov Posted December 11, 2015 Report Share Posted December 11, 2015 Paul, this is GPS- and OBD-based data, right? That is, you're using your GPS as a speedometer, and the OBD scanner to measure fuel consumption simultaneously. This allows you to take accurate data over short stretches, without the confounding factors found in all trip data and tank data, like starting and stopping. That ability, in turn, allows you to select test conditions that show the greatest effect (within reason). I say this because such data cannot be replicated without similar instruments. We won't see a big an effect in tank or trip mileages because of lower speeds, more fuel used overcoming inertia, starts and stops, cold engines, etc. Improvement, yes, just tempering expectations.

okashira Posted December 11, 2015 Report Share Posted December 11, 2015 I saw that FORScan can log knock sensor readings and timing retard to due to detected knock. I'm going to log them and see if anything shows up with 87.Knock timing retard on 87 would be the ONLY reason that the car may show better fuel mileage on 93 Quote Link to comment Share on other sites More sharing options...
ptjones Posted December 11, 2015 Author Report Share Posted December 11, 2015 (edited) I used GPS to monitor speed and used Trip Summary for distance,EV mi., Regen mi., MPG and Brake score. Used car's Temp Gauge to monitor Outside Temp. I have a 14.2mi. FWY Loop from my shop and back. Some of the Data Points are an average of two or more tests. I also controlled starting temp to eliminate that as variable. I did this testing almost three years ago. :) Paul Edited December 11, 2015 by ptjones Quote Link to comment Share on other sites More sharing options...
