And that's a very good point, Jim. And like I've said many times, I have
maintained a fleet of 33 trucks for 10 years, changing the oil every 3k, on
cheap straight 30 weight oil. No engine failures, no coking, no excessive
wear on cold starts, no low oil pressures, none use oil, none rattle, none
leak, nothing wrong with any of them. Several of them over 300,000 miles.
$ynthetics are a rip off. Extended change intervals are just plain
stupidity.

You get full marks for tenacity from me Steve :)

I don't agree with you though.

Oh, I've seen oil related wear, no doubt about it...
Heck, the old 68 ford truck I got about 7-8
years ago was one such victim.. Was run on dirty
oil all the time, and they just topped it off when it
got low.. Naturally, by the time I got it, the rockers
are clacking, the bearings about half shot, etc.
The whole engine was half shot.
In fact, that engine eventually spun a bearing, and
I had to replace it with a fresh long block.
I guess you could call that an oil related failure.
Oil change neglect can ruin an engine over time.
Sure, some may still run, but not well enough to
be any engine I'd want in a car.
I've seen plenty of 80's GM cars that had so much
crud built up in the rockers, you would need a
chisel to get it all out. That was from letting the
oil go too long between changes. Lots of those
were V6's.. Then you have all the recent ford and
toyota, and probably other brand, oil coking and
gelling problems in some hot running engines.
You won't see much of that if you change the oil
at least every 5k.
The ford truck that had the problem had 177k miles
with a toasted engine. Yea, thats not bad for a 60's
vehicle, but no big deal considering it had a 300 six
which can go for much longer than that, if maintained
correctly. Some 300's go 200-300k +..
I've got a 89 accord with 160k or so, and it still runs
very well. No smoke, runs or errors. Purrs like a new car.
But it has had the oil changed fairly regular all it's life.
As far as I'm concerned, marketing has nothing to do
with it. I've been a regular oil changer for years..
Heck, I just changed my corolla's oil at 5k about a
two weeks ago.. It was quite dirty. It looks a lot
dirtier pouring out of the pan, than just looking at
the dipstick. The engine ran a bit quieter with the new
oil, which to my mind means it was absolutely
worth changing it. Extra noise means extra wear.

If you use conventional oil and do 3000 mile changes, your car would be
better off with a full synthetic and 6000 mile changes (not exactly what I
would call "extended"). In that case, synthetics would not cost more than
conventional oil.

Does it say it uses non synthetic addatives?

You need to learn how oil fractioning works, then you'd see a clear
difference.
