Fuel Additives

Is there any point to this:



I see it's like $10-14 online, but has to be shipped extra cost, or combined with another order for free shipping

the few stores that stock it, upcharge to like $20-27

 

IMO, all fuel additives are snake oil. Money down the toilet.

 

They work. They're just not a magic pill

 

Just throwing this out there, check for vacuum leaks.
I had a vacuum line that was cracked and I noticed that my vacuum gauge was showing 18 inches of vacuum where it normally is around 21 inches. I also noticed that the exhaust was starting to pop a little more than usual on deceleration. I started with Techron and that got rid of the gassy smell when the truck sat in the garage. It ran a little better and then I saw the low vacuum reading on my gauge and found the cracked line and replaced it. The truck runs like it did before and only pops out of the exhaust once in a while like going down a really steep hill, but other than that it is back to normal. The vacuum leak was causing a lean condition and the Techron cleaned up my injectors .
Just my .02 cents.

 

Yeah check these tiny holes out.....these are for 3rz




Doesnt take a genius to figure out.....

If you have these you could benefit greatly by running injector cleaner every so often.....

If you watch your fuel trims over time, they should increase as those holes restrict......

And that's not normal carbon, its additives/ impurities in the fuel.......so its gonna take something really hot to break it loose.....

 

2rz's have these.....and may not benefit as much......

and the reason why the 2.4 dont get any better mpg than the 2.7....



I'm not familiar with the 5vz's

 

I would love to know just what is in this additive.

The only think I have ever used is FPPF It seems to work .
