You listen to Rolleye James and have black helicopters following you too, right? :-laf

Dang right!



And Murphy only visits other folks - he LIVES here at my place!... :-laf

LMAO ... ... ... too funny:-laf



What about Murphys brothers?

[QUOTE=Gary - K7GLD;

That lead-free fuel also created all the premature valve failure issues as was predicted by the paranoid crowd - how soon we forget!







I had a 69 Pontiac Executive, which I purchased new, with a 400 cid, 4 barrel carb, 10 or 10. 25 to 1 compression ratio premium leaded fuel engine. When they took the lead out of gasoline, I used lead additive for some time, then I just ran it it without lead. I also retarded the timing to run it on regular fuel. If I lost any power, I couldn't tell. I just sold it 4 years ago to a young man that has restored it. I was still running it on occasions (not my everyday commuter) and it ran great without lead and no pinging with regular gas. I suppose if I was still running 12K miles per year, eventually I would hurt the engine.

Don't want to keep steering this thread off topic - altho' we seem to have exhausted the main theme - but the big issue with the unleaded fuels was that it caused what is referred to as "valve seat recession", or the erosion of the exhaust valve seats caused by the loss of lubricity the lead in the fuel provided (lost lubricity, sound familiar?). This eventually was compensated for by engine manufacturers hardening the seats - and owners of the older engines machining the heads and installing hardened seats in the exhaust side.



Some here are too young to know - and some of the older guys have forgotten... :-laf



Main point here, is that the (paranoid) guys at that time were also making a nuisance of themselves by pointing out what they figured the "new formulation" would do - and yeah, THEY were pretty much ignored and shouted down as well - but history has a way of proving the right/wrong of things, and will in this current oil situation as well...

Wasn't bronze guides part of this conversion?

At the same time, would you want to see your great grandkids needing to wear SCBA to even go outside? We have a very clean environment in the US... most of us forget that and the fact it would be a whole lot worse if the EPA didn't push technology through...

All that is pretty much a given - no thinking person wants dirty air, food or water - it's not entirely the GOAL - but the methods of EPA that cause my own irritation - their "big stick" and "the ends justify the means" attitude is what's annoying...



And on a related note, I read a while back that the first, early strides in emissions control had accomplished somewhere above 90% of pollutant control - and that in the last 2 decades or so, all the additional crap that's been dictated and enforced at high cost to consumers, has only increased that percentage by a couple of additional points. Much effort, little added improvement!



No, I don't have that article, or a pointer - but it was in one of the major automotive publications a few years back.

I read that also... but I think that applied primarily to gas engines, and that's the reason they have recently began focusing on diesel-powered equipment.



And our diesel-rated oils are not alone in this mess... the newest gasser oils are not really rated for flat tappet cams. I've seen more than one new rebuild kill a cam during breakin on this "latest and greatest" oil...

A lot of things in life are like that.



Back when I raced sprint cars an 800HP engine cost $20,000 ... ... an 820HP engine cost $40,000.



A 1200# car cost $15,000 ... ... ... an 1175# car cost $20,000 ... ... ... . you get the point.

Big difference between examples, is that with the sprint car, the $$$ decision was YOURS - with the EPA, there is no debate - what they say GOES, especially since they now have been granted by government total God-like Dictatorship power and control of all things Environmentally related...

sorry to further derail from the original posted topic but I do have to say if the epa wanted to push some kind of technology i was in favor of it would be the technology we already have and utilize in hospitals, ambulances, and get high off oxgen places. I think the epa has lost its mind thinking less pollution is gonna keep us here. we need to reverse it. if ozone is what we need ozone is what we must "generate". if we can generate it for the people that are in imediate need of pure oxygen why not make it and vent it on large quanties into the atmosphere. I like my stacks blowing thick black exhaust down the track the fans do too so to __________________ with DPP and crazy crap milieage eating cams and sole purpose for emissions injection events on the 06's. Our country is looking toward a future crisis with all this foreign depenancy if the epa would just vent pure oxygen then we wont need to spend so much on fuel cuz our stuff would be efficient and wont require as much foreign oil. dont let me even start on that china made crap so i will leave it as consider "made in china" a warning label.

oh and amsoil is the stuff!!! I just ordered 3 quarts for my shop compresser even!!!
