Gumout All-in-one/Shell gas

[rob6773]

OK, I need to start off with I have long history of making fast cars faster. Right now I have a 67 GTO with about 450-475 hp. I've had really fast pontiacs, mustangs, and used to race my Dad's vette with a 454 and nitrous oxide.
In may I traded my Chevy truck for a '09 Honda Ody for my wife. The Ody has had a ping on and off since we got it. It was doing it all the time, dealer changed the knock sensor and it became an occassional problem. I ran 1 1/2 can of seafoam through a tank, then a few tanks later two small bottles of Techron in a tank. After reading on here about gumout I decided to try All-in-one and I found the price at Shell to be good for a change, so I filled it there (87).
With the all-in-one in the tank this van is actually fast. It feels like it is up 30 hp. This is the first time using Shell gas in the van. Techron in my truck used to feel like a few more HP, but this is real differance at all rpm. I am tempted to set-up my G-tech meter in the van to see the actaul differance.

See if there is a quantitative difference. What you are feeling seems substantial enough to measure it. Otherwise it would be hard to believe for most of us skeptics

I used to fill up all the time with 93 octane Kroger fuel in my built Neon R/T. Filled up with BP fuel one day and the car felt totally different. IDK if it was faster, but it felt way more responsive.

I believe the quality of gas does affect performance.

An acquaintance of mine swears by Shell gasolines. He says his vehicles get better mileage using them; so perhaps there's something there.

[insert discussion and commentary here about all fuels being the same, and getting delivered in the same pipeline with other companies' fuels using the same additives, etc etc]

I'm still a little spooked by Shell after the high sulfur damage lawsuits. Waiting to see if it happens again.

 

[rob6773]

I am wondering about different explanations-
cold air (maybe)
engine needed cleaning (I felt this one day after fill-up, cleaning just begun, not likely)
Honda 3.5 loves Shell gas (Maybe a small chance)

I modded up an 03 Mach 1 years ago, x-pipe- differance I could feel, cat-back- not much differance, intake spacer- small differance I could feel, 3.55 to 4.10 gears real differance.
The pull differance in the Ody is more like the gear change.

What was your prior gas? An old station the the boonies that only gets gas deliveries once a year?

If things were dirty, Techron may help. But its really only going to do some injector cleaning and carbon deposits.

Go back to your old gas and no Techron.

I think subjective.

Which exact Gumout did you use? The complete all in one has an UCL as does the Regane HM version

I had something similar with the complete all in one. About to use it again so I will see what happens this time.

I live in a pretty populated area. Old gas isn't common on Long Island. With Hess and Mobil I had pinging. Tried mixing 93 in still had boughts of pinging. Switched to Sunoco and it happened less. Started putting straight 87 Sunoco and it seemed to be better. After hurricane gas got scarce and I found no line at BP. Pinged like crazy for one night, then no ping whatsoever. Used BP two more times zero ping. Then the tank ran low and my wife filled 1/2 tank of coastal. Still no ping. Then I added the All-in-one (that treats up to 30 gallons) and topped it off with the Shell. The current mix is Shell, Coastal, and the All-in-one cleaner. This van is driven almost all short distance since we have owned it and because of that mileage is only about 11. I think the extra pull is more than subjective, it is like ported heads and bigger cams. My wife noticed the extra power and told me it was not my imagination. Rarely I have been wrong on an adjustment. When I had my '82 Mustang running a '91 drivetrain I set the timing by feel between street races and put it where I felt good upper rpm pull. At the track I ran below expectation and found the timing way too low. Cranking it up got me from 14.20 to 13.67. That is the most I have ever been off by seat of the pants adjustment and I was off by a lot, but I was watching the tach over 5K and ignoring the rest of my powerband. Maybe all the cleaners that I have used got thing to running like new, we bought used so I don't know how good it can run when new.

That's why i asked if Gumout All in One had octane booster in it. i felt the same thing.

your car has knock sensors.With all the regular fuel you've been using the sensors sensed that "ping" and backed off the timing. Everytime you start the car it advances timing til it senses knock,then backs it off.What you have experienced is the ecm has advanced the timing on the shell v-power,and given the motor more power,based on the fuel.
It has nothing to do with the additive and everything to do with how much timing was pulled on the lower quality fuel.
what you experienced is the difference a better quality fuel makes in an engine built to compensate for different octane fuels.
When you commented on "ping" one day but gone the next I figured it out.The reason it didnt ping the following day was the ecu has pulled enough timing but in doing so has reduced power output.
Just a theory.......

 

[rob6773]

Is the Shell V-power that much better than the brands? If it is it is worth the out of the way ride to get it. LI does not have many Shells.

 

[vwGLI]

Really？

Seems like I need to give Gumout a try. I'm using techron didn't notice any improvement. I always try to find something like you said. Hopefully...But Gumout all in one should not be used constantly imo

Apparently it is in the op's car.
My Harley is extremely fuel sensitive. The only fuel it runs properly on is shell premium,so I use it exclusively. My mustang has 10/1 compression ratio and is also fuel sensitive. It's dyno tuned on shell v-power,so I stick with it.
The hemi is also fuel sensitive and shell v-power nets me an average of 20mpg,when other fuels stick me at no better than 15mpg.
My experience has been very good with shell fuels. Not all stations are top notch though. I've found that the flying j shell at the outskirts of town gets me better mileage than the closer shell in my neighborhood. I attribute that to new vs older fuel in the holding tanks.
I've been using regane in my high mile hemi and haven't noticed any improvement,but fuel choice has made a difference,here in the -40 mornings.
Your results may vary.

Techron is every bit as good,or better than regane. I doubt you will notice any change,but if you do please post your findings.
Thank you

Regane comes with performance enhancer, but techron is not. This iswhat I have been observing for so long. While the end result may be the same, but the process with regane will make it more exciting

Which regane has performance enhancer. I've only seen the octane boost that claims to have amines in it,then the high mileage fuel system cleaner,the regular stuff,and the diesel stuff.
I'm not actively searching for it either though.

 

[rob6773]

Near where I live and work most stations sell a lot of 87 unless they have terrible prices. I think the off-brands sell little 93 so I steer clear when that is needed. When I buy 93 for the GTO it is usually from Sunoco. I mix Torco accelerator. Stuff definately works. I have heater pipe/vacuum adavance clearance issues that were causing me to way over or under time the engine. (I wound-up ditching the vacuum advance) 455 with 10.5 comp. I drove the car with 50 degress full advance w/no ping. That sold me on the Torco, before Torco I was mixing-in Cam2 Purple. Now I want to try Shell w/Torco. Maybe All-in-one in the tank with it. The reason I was alway Pro-Sunoco and not a Shell fan is back 13 years ago before we went Ethanol Shell was 92 and Sunoco offered 92 or 94. Now everyone's super is 93 around here.

Have you ever run across Techron in Saskatoon? If so, where? I haven't stumbled upon it down here, but I haven't been looking terribly hard, either.

Went out with the Gtech accelarometer today. Locked in second gear I gunned it from 2000-6000 rpm. The reading varied between .24-.27 G. Most of the pull it sat right on .26 G. It did not feel as fast as the other night. Might have been some wheel spin, did not hear any, but steering needed a little correction. It is pretty cold out today so the tires may be harder. Last time I used this thing it was with my GTO, when it shifted second the Gtech came off the windshield and hit me in the face.
