Just got back from topping up the tank on my DD at Chevron. On the other side of the pump was another fella just pulling up in a Pontiac. Opened the trunk and pulled out of bottle of STP fuel stuff (red bottle). I noticed there about couple dozen bottles of the stuff. Just for kicks I mention "you must really like that stuff". He says he dumps a bottle in every fill. What!... every fill?
He says he's about to hit 200k on the car and the stuff is good stuff since he's never had any gas issues and it still runs like new. He says I should use it all the time. I said "alrighty then".

I'll use Redline or Techron on occasion but a full bottle of any product at every fill...

This guy has to be pulling my chain or do people really do this?

It's just like I saw a lot of guys putting $2/bottle gas line antifreeze in their tanks this winter...when they are alredy putting in 10% alcohol right out of the nozzle.

FWIW:

I use 2-oz's of Techron or Amsoil P.I. per 10 - 12 gallons as a maintenance dose, plus a 3-oz's of TCW-3 when filling up.

STP is weak stuff, so perhaps a full bottle is needed to equal the higher concentration of Redline, Techron, or Amsoil's P.I.

Did you mention to him what you use?

Did you steer him over to BITOG or ask him if he's one of us??

The "STP myth" is similar to the "MMO myth".

STP has a proprietary blend of ingredients but doesn't contain the powerful solvents in Techron or Gumout all in one. I can imagine it requires a bottle every fill up to achieve anything.

Great marketing. They have a revenue stream for life.. or at least until it's time to figure out "STP electric charge treatment".

I have used the occasional additive in gas for kicks. My car runs like new too..and i highly doubt if i didnt use any that it would affect whether it runs like new or not.

Sounds just like all the people who think they need to keep adding a quart of ATF to their diesel fuel tank. "My brother's friend's cousin used to do this forever and his engine never blew up" so of course everybody else should do the same.

What they don't seem to realize is, your engine should not blow up on a regular basis whether you use the snake oil products or not. Imagine all the money this guy has spent over 200k on STP. He could most likely afford to fix any possible problem with his car if he just put that money into a savings account.

My motto is "people are stupid". I've yet to be proven wrong.

No I didn't - he had several bottles in a box in his trunk. I could see all the about 1/4 or so tops of all the bottles. Took 1 bottle out, shook it well and poured it in the tank, then did his filling. Seemed proud (cracked a smile) dumping it in the tank. Had a rag in one hand I guess for spill, but he didn't need the rag and put it back in the box.
I was thinking "he's going to give me the empty bottle so I would stop at a auto store to get this magical stuff, or maybe hope I offer some bucks to buy one on the spot".
I should have told him I use two bottles every fill so my car will run twice as long as his. Three bottles if I'm feeling naughty.

My additive trick?

Just use Top Tier gasoline as much as possible.

Marathon's been doing that since 2006. STP's fuel additive is/was a competitor of Chevron's Techron additive. The Marathon/STP relationship continues to this day.

The STP Gas Treatment you buy across the counter does not contain PEA - it's basically a fairly old formulation of Stoddard Solvent, petroleum distillates, napthalene, etc.

For Marathon to stay competitive with it's gasoline product, the STP additive in Marathon gas might be something quite different than the STP you can buy. It probably contains PEA. I couldn't find any information on this, but I doubt that they could keep it a secret for long.

I just noticed that Marathon is not listed as a Top Tier gasoline retailer, so maybe the STP in Marathon gasoline is really the same as the STP you buy across the counter.

Right. It said 'Studebaker Tested Products.' Studebaker owned STP at the time.

Costco near my work is top tier, and they are the cheapest around.

I get in there and buy gas nearly every time.

I haven't put anything in a fuel tank in YEARS besides gas.

The only top tier gas I have in town are bp and Shell and they are consistently 40-50 cents more per gallon. I pony up now and then but I think they are a little more expensive than your average to tier stations. We have so many Speedway gas stations and Murphys or Kroger is always the lowest in town. BP and Shell have been $3.99 all year I think while I've been consistently paying 3.60 at Murphys.

I use tc-w3 in every tank,for everything I own that burns fuel.
My forklift has 2000 hours and runs better than the one we lease with 600 hours.
My generators and compressors have never required any type of carb service,nor has they had any issues with any rubber parts and I've got 2 compressors with over 10000 hours and one of those is closer to 15000.
So folks can say whatever they want about fuel additives. In my experience when compared to other crews that own identical equipment my stuff lasts pretty much indefinitely so far.
A few pennies vs hundreds in service costs.
