New Unisaw - The flag is back

Didn't see Mythbusters?

Maybe your net was simply much lighter than the steel gate?

The gate up and latched also improves pickup box crash performance. I would also imagine a lowered gate becoming a projectile in a crash.

I'll bet your web gate trapped enough air to create almost the same cushion as the steel gate.

Thinner air requires a leaner mixture, but overall horsepower is reduced.

This is demonstrated to me every time I fly.

I can't speak to milage in this situation but I was always taught that increasing Octane reduced knock caused by preignition of low octane gas. This has nothing to do with valve chatter.

Over the tehachapi, and the pacheco pass, but the bulk of the route is flat san joaquin and coyote valley driving.

Please quote carefully.

Leon said that, not me.

I think you're absolutely right about the valves, and can't figure out why octane would have anything to do with valve noise.

On the other hand, in ground school I learned that detonation is caused by too low of an octane, with the compression burning the fuel explosively before the plug fires. Pre-ignition is caused by cylinder hot spots and burning carbon deposits. The carbon deposits are usually artifacts from too rich of a mixture resulting in too low cylinder head temperatures.

Well, let's check. Whose ad is on your pocket protector?

Just back from a week through Colorado and SE Utah in the wife's '06 LandCrusier. I have noticed the same phenomenon this trip and in previous trips in my '01F250 Power Stroke. Mountain driving seems to improve fuel mileage by as much as two mpg. I theorize that much of it is due to decreased speeds, often 45 to 55 mph vs. 75 to 80 on the Colorado, Utah, and New Mexico interstates. The LandCruiser's trip computer fuel mileage drops down under 12 mpg out in West Texas where the interstate speed limit is now

  1. If you're not already running synthetic oil, DO. You'll not only increase your fuel mileage (one mpg, maybe more) but you'll change oil less often and reduce wear on bearings, rings, valve train and the like.

Yeah, I misspoke there.

Hmm. I have a /leather/ pocket protector loaded up with a five-piece Rotring set - it matches the leather case for my nice yellow log-log Pickett N600-ES. I suppose now I hafta go find some masking tape to put on my s/s glasses frames. ;-)

What? I don't see any nerds...

Yeah, I'm running synthetic, firggen 0W-20 as per Toyota's strong recommendation over 5W-20. If it were not synthetic I'd be skerd as heck.

I heard that. When I went to Amsoil's Signature Series 5W30 I watched the oil pressure gauge drop from just above the half-way mark to about two needle widths above the quarter mark.

"The main reason 5W-20 or 0W-20 oil was specified for your engine is to increase the CAFE (Corporate Average Fuel Economy) reported to the Federal Government. CAFE is the combined average fuel economy of all of a vehicle manufacturers product line. Minimum CAFE levels are specified by the Federal Government. In order for a vehicle manufacturer to continue selling profitable large trucks and SUV's, which typically have poor fuel mileage ratings, as compared to smaller cars, and still meet mandated CAFE requirements, they must also sell enough of the smaller cars which have much better fuel economy ratings to offset the poor fuel economy ratings of the larger vehicles. For model year 2001, the change to a 5W-20 oil will allow Honda and Ford's overall CAFE to increase by a very small amount, typically in the tenths of a mile per gallon range.

5W-20 oil is a lighter viscosity than a 5W-30 oil and therefore has less internal engine frictional losses, or less drag on the crankshaft, pistons and valve train, which in turn promotes increased fuel economy. This increased fuel economy is virtually undetectable to the average motorist without the use of specialized engine monitoring and testing equipment under strictly controlled test track driving when compared to a 5W-30, 10W-30 or a 0W-30 viscosity motor oil.

('01 4.0l 6-cyl, auto, super cab, 4WD, AC) 65K miles. Apparently it was in an accident before I bought it (*NEW*) because the pait is all cracking and there is evidence of replaced parts. :-(

I know an Amsoil franchisee who claims the same thing, even after he seized an engine on the stuff. ;-)

Mine doesn't really advertise anything, it just has a "United Technologies Hamilton-Standard" logo on it.

Flashing on conversation in the dentist's office the other day. The lovely Doc Irina and her assistant were laughing about the guy who had come in to fix their computer, who had his glasses held together with masking tape. They're both Russian--I had to explain the concept of "nerd" to them.

Oops, I lied; the Amsoil Signature Series is 0W30, NOT 5W30. I actually run the Series 3000 HD Diesel in my Power Stroke which is 5W30. The F250 has in excess of 180k miles all but the first 8k on Amsoil. I put 183k miles on a '91 Checvy 1500 Silverado 305 gas rig, all but the first 4k miles on Amsoil and the Land Cruiser is approaching 60k. A friend has gone over the 300k mile mark on his '96 Dodge Cummins. We both run the oil 24,000 miles between changes with filter changes at 6,000 though I've gone to 8,000 between filters since Amsoil came out with their EA line of filters (they guarantee them 12,000 miles).

It is not uncommon for "new" vehicles to be delivered to the dealership damaged and that does not mean that they were in an accident. Way back in January of 1978, the first year that I worked for an Oldsmobile dealer our body shop and the Oldsmobile rep were inspecting the roof on a new Cutlass. Setting on top of the roof panel was a huge hunk of ice that apparently had some road debris mixed in. The hunk of ice had been sliding around and literally "sanded?" a hole in the roof of the car. You had to see it to believe it. The transport driver brought it to our attention that the seats were wet and the headliner was soaking wet.

We also saw a quarter panel that had been ground down so thin that you could push it in with your finger. This vehicle was also straight off the trans port truck with factory paint.

Both the above mentioned vehicles required major panel replacements.

Then there is the very common damaged caused by hail storms that will damage hundreds of new vehicles setting on the dealers lot. While minor dents can be repaired that type of repair soon becomes more expensive that replacing a bolt on panel or fender.
