As most of you guys may know I tested to see how many miles i'd get out of my es300 for 1 full tank till the empty light first appears..

1st test: The car went 270 miles on one tank. Knowing the gas tank is 18.5 gallons and the light comes on with 2 gallons remaining that gave me 16.3 Miles per Gallon, and the car was driven roughly 80% highway and 20% city..Pretty Bad


Intermission: I decided to use the BG fuel injection cleaner and run it through the brake booster line. Ran the car for about 10 min while it used up all the cleaner. Black smoke was abundant out the exhaust, so we can safely say something worked.


2nd test: The car went 335.5 miles on the tank till the gas light appeared. With all calculations it comes out to about 20.3 MPG which is a significant jump IMO. Still not the best, but any improvement is better than no improvements right?

Anyway, Chevron 89 octane was used in both tests, my next test is going to be with 91 chevron. Stay tuned on this Es300s quest for better MPG

 

told you that bg helps

 

I forgot who it was, thanks again for waking me up and using it

 

how much injector cleaner did you pour down the line? And can i just use my pcv opening instead? Also did you just pour and drive? or pour and idle? or pour and kill, then restart 15 mins later? Ack.... so many questions.

 

Yeah im pretty sure u can run it through the pcv line but the brake booster line is much easier to get to IMO, i let the car idle as the fluid is used up slowly (it was one can) u can find it on bgprod.com , and when it was all done, i let the car idle for 5 more mins before i rev'd it and took it for a test drive.

 

Mkay, a few final things, do you just put the hose in the can and let it suck it up by itself, or do your pour using a funnel? Also, what is the big differences between this stuff and seafoam, in your opinion?

 

Well the way I did it is with a tool that punctures a small hole thru the bottom of the can, which then runs thru a hose with a valve adjuster(which i set very near closed, so it runs very slowly thru the hose) then runs inside the car via pcv valve or whatever u choose to run thru it.

I have never used seafoam but i hear a lot about how it can ruin plugs and what not, so I just decided to stay away from all the headaches with that.

 

You should calculate it by how many miles since your last fill up divided by how many gallons went in. That would be more accurate. Instead of saying there is 2 gallons left when the light comes on. For part 2 of your test, thats cool tho

Weird my Solara gets kinda crappy mileage too. But the ES aveages like 28 mix. Both have an 18.5 tank.

Does bg make a machine for that. I know they make coolant and tranny flush machines, dont know about fuel injection stuff though

 

hmm interesting....Ill look into that calculation method

No its not a machine, its just a thing that holds the can and punctures it from the bottom and runs it thru a hose into the car

 

oooooooh ok I think youll find out you mpg #s will be better using that method and i only say that cuz my idiot light comes on whenever it feels like it say 1/4 tank or less. hills or whatever makes gas move away from the pickup. and when i fill up only like 13 or 14 gallons go in. Anyways keep us posted and btw your ES300 looks really good!

 

Thanks!!! Honestly I wish I had a 92-93 manuals, i cant imagine how fun that would be to drive......Yeah ill do use that method in my next test.

I have to retest the 89 octane with your method then do the 91 octane test also to have an accurate difference between the two using the same method of calculations

 

might be a dum question but hell im asking it lol, what about the fuel injection cleaning walmart does for like 30$, is that the same thing or what, and how good does that work, if so does it even work at all.

 

I've used Seafoam a few times it it seemed to work..

ANy updates on the MPG..

 

this might be a noob question... but can you show me a picture/writeup of where you put the cleaner through and how you did it, thanks!

 

idk y but mine still gets a lil more then urs and we have the same car, i get about 350 miles per tank and thats driving like a ***** lol, almost or around 380 grandma style, but i mainly average about 21-22 mpg
