Re: Anyone Here Use Fuel Additives ?

As for Sunoco, they had a high octane and a low octane. A mixing valve combined the two in different proportions.

I have heard that some of the blending is done at the depot. I haven't paid attention in a long time, but different brands used to be different colors so you could identify the product.

As for a 100 mile pipeline, I suspect it doesn't just run from point a to point b. Like a highway there are probably on and off "ramps".

On Long Island, maybe other places, Hess was delivered by a private trucking company. The Hess fleet was union, they went on strike and Leon sold the trucks and contracted out. There are also independent stations who spot buy. Sam's Club, WaWa, and some other big chains do this. They do not claim to be a gas brand, just a gas retailer.

I would like to know for sure how they specifically handle these things today.Chevron claims to have Techron in their gas. If they didn't there would be annoying TV commercials for the latest class action lawsuit.

That is exactly what happens. My friends father owned a Citgo, guess what gas he bought throughout the 80's and 90's? Whatever brand was at the Boston terminal which was cheapest, could of been shell, arco, exxon, citgo etc. It was all the same save the additives.

Showed me how you could tell 93 from 87 and 89, it would dissolve a Styrofoam cup,

Re: Anyone Here Use Fuel Additives ?

A while ago I also read that some states will recommend different octanes based on state and altitude.

Re: Anyone Here Use Fuel Additives ?

Re: Anyone Here Use Fuel Additives ?

I've been thinking about this since I added the Lucas Fuel Treatment to my 2013 JGC V8's fuel tank. Aren't we only accomplishing just half the cleaning needed when we run in the ECO mode and the MDS drops 4 cylinders; the same 4 cylinders every time? As I've thought about this as I drive, I've been choosing to stay out of ECO mode by just tapping the gear shift lever to the left when in Drive after reaching the cruise speed wanted.

Also, occasionally I'll run the engine up to 4,000 rpm when in the lower gears. Fun!

True to a point. But I don't believe the MDS kicks on until the engine is up to operating temperature, and the thermostat opens. From start up until then it bangs on all 8 all the time. Same with any kind of hard acceleration. If you use a fuel treatment and stay out of ECO mode, (which I never use anyway, because if I wanted economy I would have bought the V-6), the 4 that shut down will get a bit less flow than the other 4. But they'll still benefit from the treatment.

Same manual also indicates that you just don't get a perf boost by running a higher octane on the V8, but you might get a perf drop by running lower...

Nothing at all wrong with running a higher octane than recommended. Doesn't buy much other than the satisfaction of running a higher octane--although there are rumors that there is more additive in the higher priced variants at the pump.

Haven't Seafoamed the V8 yet, probably will one of these days, then give it some Techron a few months later.

The higher octane itself provides no more power, but it does force the computer to advance the timing to avoid pinging. That provides a little more power. But the computer can only advance the timing so far, so at some point higher octane is ... pointless.

I would not be surprised if Jeep is doing the same thing by saying you can use 87 but we recommend 89. You probably need the 89 to advance the timing enough to seek out the 360 hp.

? An engine computer that ADVANCES the timing to avoid detonation?

More likely it just lets the advance go a bit further on the higher octane, or if a turbo allows boost to stay higher--not by measuring the octane but by not retarding or cutting boost or enrichening to avoid detonation.

Buying a Hemi does not make economic sense. Arguably even buying a Jeep does not make economic sense.

Octane rating wars make even less sense...but it appears we are overdue for one.

It didn't matter what brand. There was yellow tape across the pumps of most every station in town. So how can the gas from Mobil be any different than the gas from Shell if it all came from the same pipe?
Because the stations do tend to buy it from the same place and the additives are added in afterwards.....

Not that I'm a pump additives cultist.
