The mileage and power increase is probably in my mind, I will give you that, but I dont care its how I feel that counts. I can swear I have more power(unconfirmed) with bio or wmo. Different diesel stations have differing quality fuel which is probably throwing off my "guestimate", sometimes when I fill up on #2 and dont add any supplement, I swear sometimes my truck just drinks the fuel and fast and my power is lacking, but it is probably from the quality of the diesel.

The injectors make a sort of clankity noise that you can hear, at least thats what Im thinking Im hearing, if I run #2 only. I had a regular injector in place of the LL before and it clanked pretty loud at idle. I should probably get a regulated return soon, always wanted one but life gets in the way.

Why did you remove your reg return?

If you don't run WVO, why are you missing it?

I know a guy that swore he had more power when he put on a different TB. Tested it out at the track and he actually ran a worse time than when he had his stock TB on. That was what he drove home with. I also know people who felt a great increase in power with some fancy chip only to have their joy dashed when they saw the dyno slips. The wife swore that her new glasses weighed more than her old ones. They were definitely bigger and it gave her a headache. We went to the post office and put it on their scale and her old ones were actually a half ounce heavier. That day the headaches went away. Miracle, wasn't it? I have learned that the only thing that really counts is the objective tests where quantitative analysis is done. OTOH, if you want to pay for the feel, who am I to say you cannot.

When I test additives, I use the SAME station and the SAME pump. The route will be highway since that is the least subjective. I would fill up say 10 gallons of B100 into the tank and put in say 30 gallons of D2 from the same pump so the fuel quality is about the same and the accuracy is as good as I can make it. That gives me B25.

I have seen injector tests and I don't think the slight clicking can be heard over an engine noise when you are in the cab. That is, unless you are a dog with that good hearing or with special equipment to measure it. Like I said, the RR changed the sound of the engine. Actually only 1 injector is really involved. #8. Nothing else changed. So how do you account for the fact that the engine sound changed with the same fuel if it is not for the combustion characteristics?

Sorry for the bad choice of words. I never took it off. It just seemed quieter when I had it on.

I miss biodiesel, you have to collect WVO to make biodiesel.

Aklim,

I see what you are saying unfortunately I dont care enough to actually do a scientific test, LOL.

Im confused as to what you mean with your regulated return being better when you had it on and how you never took it off, but then you refer to the RR as being in the past, I dont understand.

Im wondering if I need a regulated return if I know what the tapping of #8 sounds like because I had a normal injector in its place. It taps like a SOB, so I put the LL back in and its fine. If I dont hear it tap anymore then should I skip the RR?

Im thinking the viscosity of my altered fuel is what is more forgiving for my injectors, what Im hearing on #2 only, is probably air? My guestimate is leading me to believe a more oily fuel is helping with the air issue?

Do a scientific test. It is any eye opener.

I never really took it off except that one time a couple months ago when I caused a leak. I had to take it off while I got the cut hose replaced. Once I got the hose, I had it reinstalled. My tense might have been wrong.

I wouldn't. The reason the thing tapped more with the LL injector off is that the lack of fuel in #8. From what I know, and it might be wrong so somebody correct me, is that #6 fires before #8. Being that the #8 is way back, it doesn't get enough fuel. The RR plumbs fuel into both ends of the fuel rail so there is no shortage. Like I was clumsily trying to say, with the RR on, it quietened down. When I temporarily removed it, it became noiser again. Put it in, and it quietened down. All verified by the wife-o-meter. Since the wife knows next to nothing or less about cars, she is the perfect test.

Another thing is that people do the in tank mods to remove the quick connects that sometimes leak air.

Now just a few posts ago , you were bustin balls about using scientific test instruments to test noise levels over engine noise etc ..... which is it ?

I'll also add that I know better than to doubt my or anyone elses "wife-o-meter". I swear they can hear better than dogs or rabbits or whatever... especially if you are talking about them or your ex-girlfriends....

[tomjon]

Back on topic .....There is a link at the Opti-lube site that links to an independant test sponsered by (iirc) Dieselsite.com.
It's a good read with some "eye opening scientific results".

When she drives it or drives in it, if she says she hears less noise and I didn't tell her what I did and what the side effects are, her reports are not contaminated since she doesn't know what to expect it to be.

Or mistresses. In fact, sometimes, when it comes to that, they hear things that aren't even said or thought of.
