The manufacture claims in the three ball test, that they have the lowest drag of all lubes. I can't prove that it has made my engines last longer, I change oil every 3K and add 4oz. as the manufactures suggests. What I do know is that it made my old diesel tractor a lot easier to start, and I've used the lube in numerous electric motors that were about to give up due bearing drag. Ever single motor I relubed the busings or bearings with tufoil is still running, some for more than 8 years. I've also saved numerous sealed bearings by putting a small hole in the dust seal and then injecting tufoil into the bearing. I also mix it with a high quality lithium/moly grease for gear cases and wheel bearings. No a single bearing lubed with it has failed. I also add it to manual transmissions and really smoothed up the shifting. The patent on this oil claims that their PTFE is a dipolar molecular makeup thus it not suspended but in solution. All I know is that it does not settle out, I got jugs of it over two years old without settling. So maybe it just a good oil, but everything from hair dryers to can openers to tractors seems to work fine with it. //ck ------------------------------ Date: Tue, 21 Oct 1997 13:37:17 -0400 From: Darrin Liesche Subject: engine change? As a new subscriber I have some questions I'm hoping someone out there can answer. I currently have an '87 F150 with the I6 engine, 4spd with OD manual transmission, and four wheel drive. I'm considering changing to the 5.0 V8 provided this is not too expensive of a swap. Hopefully, with as many salvage yards as there are around here, this will not be too difficult or costly. My questions are as follows: Just how much more horsepower can I expect from the V8? Which engine is more reliable in the long run? Can I keep the existing transmission and mate it to the V8? Are engines which are used in four wheel drive trucks any different from those used in non-four wheel drive trucks? In other words, if I change to the V8, must the engine come from a four wheel drive truck? Is my current transfer case compatible with a V8? Thanks in advance for any responses.

I would think that an electric fan would free up a little extra HP, since I can tell a significant difference in acceleration when my fan thermal clutch engages. They would cause more battery draw at idle, but then they may give you better A/C performance at slow speeds/stop and go traffic.

What did the oil pressure do at higher engine speeds? What do you mean by the crank "slopping around?" A few hundredths of an inch of bearing wear would be enough to drop oil pressure severely, but I don't know that you could even feel any looseness in the crank with really shot bearings. If the crank was moving very much out of alignment, which it sounds like you're describing (maybe the shop is telling you that), you would have some way major problems with the pistons up in the cylinders, and maybe the connecting rods and wrist pins, too. At that point, nothing short of a complete overhaul would be worthwhile. >I can see where the timing might have an effect, but I would expect >that it is was off a tooth it would running rough with a bit of a >backfire or something like that.

If it was my truck, I think I'd have it towed to another shop, preferably one with some reference from a friend or co-worker, and get another diagnosis. I know the tow is expensive (and paying off the shop you're in now), but it sounds like you're already looking at some big bucks repairs here, and spending a few more might be a worthwhile investment in not getting screwed. Bottom line: an expensive repair to get things right is worthwhile, but throwing good money after bad is just not prudent. Good luck. Dave R.

They thought that the magnets would separate any long chains of molecules that had inadvertently formed during production of the fuel, transport, etc. By breaking these long chains up, it was supposed cause the fuel to burn more efficiently. As for the Air tornado, I am not sure if this was stated in the original article or not(I didn't read it, I just deleted it), it causes turbulence, actually a spiralling motion, in the air flow. This is supposed to create a more homogenous mixture of gas and air. However, there is already plently of turbulence in the air flow, from your air filter, bends in the air intake tube, your upper and lower intakes, and finally when the air stream crashes into the top of your heads. It seems like a good idea in theory but rather poor when put to practical use.

(M-block devotee) Not to get into an argument, but the air/fuel mixture isn't near as cold as outside air. Plus, it only hits the face of the valve, which is treated to withstand that environment. Where the cold air would damage the valve is on the stem, by warping it.Bill Funk ------------------------------ Date: Tue, 21 Oct 97 11:57:29 PDT From: "Josh Armstrong" Subject: 4.11 Gears Bronco???

When NASCAR went to the Craftsman Truck series races, they spent a lot of time in the wind tunnels determining what was the best configuration for the trucks. The end result, a compromise between aerodynamics and "stock" looks is what we see today - s bed with a cover on it. For the road, the best for reducing aero friction is a cap the same height as the cab; second is a cover, and third is a tailgate in the up position. Putting the tailgate down or removing it is the worst of the choices. Here's why: with the tailgate up, a "bubble" of air forms in the bed, which slowly rotates from the cab top to the back, forward on the bed floor, up the cab back, and so on. This bubble is seen by the air flow as a fairly aerodynamic part of the truck, and the air flows over it. Letting the tailgate down allows the bubble to spill, and the air flow sees a cab followed by an empty space with a floor that moves. This is not 'clean', and fuel mileage suffers. This is counter to what 'intuition' says, as intuition says the air sees the tailgate as a huge air brake, but it evidently doesn't.

Here's the line...The magnets align the molecules in the fuel, so they can better atomize producing a mixture that will burn easier, and thus provide better fuel efficiency. No, wait, that's not it... The magnets align the molecules in the fuel, so they can ignite easier with the weak spark provided by today's ignition systems(!), and thus provide better fuel efficiency. Ooops, wrong again... The magnets will actually magnetize the fuel, allowing it to flow in a more orderly fashion in the fuel delivery system (intake manifold), reducing friction losses, and thus provide better fuel efficiency. Or is it... The magnets attract cows to the air fuel mixture, which produce methane, a much cleaner-burning fuel than gasoline; this helps reduce emissions. Yeah, that's it... The cow one is definitely the right answer. Bill Funk ------------------------------ Date: Tue, 21 Oct 1997 12:11:37 -0700 From: Michael Wray Subject: RE: FELP.

The pressure went up, but not nearly what it should have. But as soon as the engine was warmed up a little, the gauge would drop to 0. :( What do you mean by the crank "slopping around?" A few hundredths of an inch of bearing wear would be enough to drop oil pressure severely, but I don't know that you could even feel any looseness in the crank with really It seemed like that crank was not spinning smoothly and well balanced. It seemed that it was out of balance a little. The engine would kind of move as if something was out of kilter. There is also a slight clunking sound, not a metal on metal sound (which is good) but more of a chungging sound. MAN is this hard to describe. :) Yes, pretty much. The severity of the symptoms, though, would depend on things like what the cam profiles are, whether it was advanced or retarded (direction of the error), etc. The engine is totally stock as far as I know.

I begged to differ but, he was > adamant about his fact. > Is this true and do I owe my friend an apology for not believing him? Lets see.... The air is thinner, so we can get more in???? Nahhh. That ain'r right. In a normally aspirated engine, you get less. In a turbocharged engine, higher altitude makes no difference since you compressing the air anyway. If you ever step into a piston powered aircraft you will notice that they have a mixture lever. This is so they can lean out the mixture at altitude (some have auto mixture controls). A normally aspirated engine will only bring in so much volume of air. If that air is thinner (high altitude) it weighs less. Since mixture is based on weight, not volume, you must reduce the amount of fuel being introduced to the air otherwise the mixture will be too rich. Mabe that thin air reduced the drag on your vehicle? :-) Also, you said powerstroke?
