OK, I have been try to give "intelligent" replies all day to push me over 1000, but no luck. I thought I could do it on the coffee cup thing, but didn't have enough witty remarks to make it.
So I have decided to post this totally useless posting to put me into the 1000+ club. I feel like a hero. I have started dozens of amps, but have completed none, but at least I am now over 1000. Didn't even finish high school, but I have this.
Moderators, I am on my knees, please don't take it away...

It's kind of like watching your car's odometer to see if you can guess where you'll hit the 100,000 mark.
My Volkswagen is getting very close...

You could have made the last post seem intelligent by saying "Cathode", "Pi-Filter" and Transconductence.

Congradulations! BTW my Ford Ranger is on 316,000

Hey, check it out....

Modern cars/engines get good high mileage figures. In the old days, like the 40s, the flat-head Fords needed a valve and re-ring job after 50k miles. Modern lubricants play a big part in longevity I believe.

sounds like me...

Fuel injection is probably one of the biggest things that has made engines last longer. They more precisely meter fuel into the engine and being as the gas is controlled better, less of it ends up in the motor oil. This causes less contamination and dilution of the oil which makes the oil last longer and keeps the wear down on the motor. The oils have gotten better, and I think you'll notice with that and the fuel injection that motors were running much longer. Before if you kept oil changed at 2-3000 miles the motor would last much longer, these days double that is quite safe and the motors can last 200,000 miles no problem.

SE oil was a BIG step.
Late 1960s Ford Windsor fed SC-SD oil sludged-up in 100K, and wear was evident even before it clogged.
At that, my father remarked how much better it was than the Ford Flathead. (However Chevy and Plymouth Sixes of that vintage seem to run far-far past 100K....)
Late 1970s motor made in the same factory but lived its whole life on SE-SF was zero-sludge and just broken-in at 238K.
A large part of the "SE" specification was an actual long-term run in an Olds 350 engine. Take the bearings out and weigh them before/after... that tells you just how much metal got rubbed-off. Beautiful empirical test spec. No BS.
Yes, fool-injection is another aspect. Both the above engines were carb, but the first was sloppy-rich and the second was smog-lean. Even the smog-carb was sloppy, and FI can be better, but rich-soot alone does not explain all the differences I saw in the two engines. Soot alone does not cause wear (though it breaks Windsor 289/302 oil pumps and THAT leads to big wear). Soot darkens varnish but varnish happens without soot, and much less on SE.
We're up to SM/SL spec oils now.....

I always liked the old flat head Ford engines. I also had two Lincoln Zephyrs, with their V12 engines, which were basically a flat head like the Ford. The V12 would have been more successful with the modern oil. It was a sludge pump with the oil of those days. It would be interesting to know how the flat head Ford V8 would hold up with modern oil. Those engines are getting popular now, with many after-market restoration parts available. They were very smooth running too.

It's kinda hard to be a post whore on this forum, that's a good thang. I gotta say I was a bit confused by the single ended motor oil for a moment. I'm completely lost when looking under the hood of a modern car.

Me too, Nothing else sounds like a Flatty.

I started the whole car mileage talk and jinxed myself....My VW got backed into by a huge International Harvester dump truck (luckily it was a City Street and Transportation department truck and was insured).. It's not my fault but the estimates that I have gotten are very near the amount that insurance companies would total it out :( ....98,700 might be all it ever sees. FIngers are crossed....

I'm running Mobile 1 Extended in the 01 Taurus with over 125k on it. Change every 12,500 and run a good filter on it. I run Motorcraft but the parts guy said to run a Mobile 1 filter also ($10) so I might next time..if it is a free flowing type. Costs alot but last 5 times as long...So far so good!

Only 74 more to go for 2000! (Good thing its not about actual substance or content... :D )
