Probably a sticking injector, getting out of lean fuel trims... A weak coil mag field, from high resistance wire, maybe. Measure resistance between contacts at injectors to see if it is in spec.

First, how do hear a noisy fuel pump and secondly, fuel pump bearings are sealed units.


So as you know, PIB, the dispersant, helps on fuel droplets size decrease. Why dont you see enhancement on oil mixed with fuel, from that? I know you cant see UEL as most do, but fuel atomization in a injector system is case for better efficiency, hands down!

Right, as I said it assists "fuel atomization" post #3917941, or didn't you get the notice?

And for your information, this PIB is not a dispersant, it is a PIB of specific molecular weight that is dissolved into the fuel or fuel additive. I know, I have developed fuel additives that included PIB's and other chemistry's.

I have no idea what you are referring to here.

Who is most, and what exactly are you referring to here. What is a UEL?

As I said above it assists "fuel atomization" post #3917941, or didn't you get the notice?

I wish I could have warned you off of that line of questioning.

Yes, I think it is better for me to refrain doing such lines...

Has anyone asked the $64,000 question before?

What additives contain the polyisobutenes that are good for fuel atomization?

i put tcw3 in my bike. Its got 4 finicky hitachi carbs.
I should try that, it will probably do the same thing and be cheaper.
 
I always wonder why everything here always needs an explanation.

Mechanical fuel pump had less noise. Not sure what was binding/clacking/clicking since I didn't take it apart. Check valve or piston noise/wear....!
The noise was from the electric motor was most likely from the load on it. So, that sealed bearing became more quiet. Ever see the guts of different types of in tank fuel pumps? Or make the parts that are used to make that pump? I have. I myself do like the grinding stack diffuser impeller design that do not need a real after pump fuel filter. And I hate the tolerance level on fuel pump parts. But, they work, some almost forever and others not so long.

Most people are to deaf to notice the mechanical symphony that plays in a vehicle. So sad.

Real question is, what does Lucas put in the bottle to clean, lubricate, ...?

HMWPIB - high molecular weight polyisobutylene

Viscon. Marketed to diesels, though. I only tried it once, would like to find it closer to me for more trials, though. It was some stringy stuff!
 
Back when I had my Mazda and had tons of spreadsheet data on mpg, I posted this: http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=303103

Looks like whatever hosting site is no longer around and the excel spreadsheet snapshots are gone, but the info is still in there. Probably not statistically significant to 95%, but it was a solid trend. The tanks with FP60 and UCL averaged higher mpg vs no treatment. That car turned much more consistent mpg numbers tank to tank vs my cars today, and was a better platform for testing.
 
thanks surfstar,

i found the viscon threads and am also hoping to find some for my trials.....seems that they only sell in California. When I go for my annual trip to Texas(visit aging parent) I will stop at a few truck stops and look for it.

Have you tried Lucas UCL or MMO by themselves?

What ratio of each are you using?

Yes, I first used Lucas UCL and that's when I noticed the exhaust pipe getting cleaned from soot. Then I got my hands on MMO and used that by itself for a while. Now I mix Lucas UCL and MMO 50/50 mainly because I can get UCL at any truck stop for a decent price, but MMO is harder to find. I mix the two so that my stash of MMO lasts longer.
