engine treatment
 

I bought some for $1 at the dollar tree. It has methanol and other proprietary stuff in it. the car warranty is over and it has 57k miles with no clue if it has been done at all. I buy mostly Shell premium gas. What do you think?? I put half the bottle in my dad's toyota for almost stalling on us at red light in D. I did search and seafoam was it.
THANKS

you bought some shitt at a dollar tree and you're going to feed it to your $30K+ Z?

:eek:

:iagree: me no like, bad medicine

this isn't some POS Toyota Ya know

fixed

First off, never add anything to the oil or gas "just because."

Unless your engine has serious problems, just about any additive will probably do more harm than good. Almost all the additives I've seen are meant for worn out engines that you want to get a few more miles out of before rebuilding/scrapping or they are snake oil. For extreme conditions (eg, supercharging, racing), there are some additives that can help but I don't think you're going to find them for $1 unless they are off-spec/out-of-date/stolen/&c.

There are some additives that will help specific problems but those should be used on an as-needed basis - if it ain't broke, don't fix it. Assuming regular oil/filter changes and good fuel, you shouldn't have to add anything (other than the rare dose of injector cleaner) to the gas or oil.

Are you asking what we think? What I think is that it is crap and a waste of a dollar that would have found a better home in a stripper's G-string or a homeless person's cup than at the dollar store.

(Oh, Reported)

That was my second reaction.

:eek:

:facepalm:

No.

If you want to use a gasoline additive I would recommend RXP. It's $10 a bottle but you can feel the difference instantly.

These latest threads have been so full of win :drama:

Use Drano for best results. That will clear everything up!

scientific reason
 

Here would be a good reason. methanol and aluminum oxidize. use to be the MTBE that was in gas but outlawed.

One of the drawbacks of methanol as a fuel is its corrosivity to some metals, including aluminium. Methanol, although a weak acid, attacks the oxide coating that normally protects the aluminium from corrosion:

6 CH3OH + Al2O3 → 2 Al(OCH3)3 + 3 H2O

The resulting methoxide salts are soluble in methanol, resulting in clean aluminium surface, which is readily oxidized by some dissolved oxygen. Also the methanol can act as an oxidizer:

6 CH3OH + 2 Al → 2 Al(OCH3)3 + 3 H2

This reciprocal process effectively fuels corrosion until either the metal is eaten away or the concentration of CH3OH is negligible. Concerns with methanol’s corrosivity have been addressed by using methanol compatible materials, and fuel additives that serve as corrosion inhibitors.

Peter Rooter is best!

Thank you, Science Guy!!!

a can of seafoam in the gas every 30k never hurt anything, unless it was really crapped up and seafoam broke the crap loose and it got sent to the injectors then it hurt things, kinda like flushing an auto trans for the first time at 100k miles.
