Silly boy you. :p Hey just because you may disagree with us, does not mean you can't post and explain your position. Man that's what this forum forum is about. So please do post your idea's, just do it without being condsending or hateful. I don't find anything fulfilling about just talking about something everyone thinks the same about.

Myself I was always taught that a chain in an engine does not stretch, just wears. I never had anyone with medalergy back ground explain why it would not stretch, so I have always had my doubts about the way I way taught. In other words is there someone here who could give a difinative answer for me?

What we call chain stretch is the elongation of the chain from wear. This wear is the result of operating the car without changing the oil frequently enough. The worse the maintenace the more the chain wears. Chain wear is probably the easiest way to "measure" the wear on the engine.

That's the way I was taught, but it does seem like it could actually stretch some if enough tention was applied. Maybe that kind of tention never happens in an engine? I guess you would break cogs on gears and bend shafts before you could get enough force to stretch a chain.

Now if only they could figure out how to keep their exhaust manifolds from leaking.

Nope, I've been personally attacked, insulted and lost my cool in oil threads. If anyone is curious about my experiences and methods, there are plenty of threads of the past from which they can find out. They can also see how bad I lose my cool when attacked and insulted.

I have my own ideas and methods that have proven to get many miles from my engines. Others apparently have their own methods. Whatever works for them, that's great. I will continue to do what has proven to work for me.

Have a great day,

Yes, I know you mean. Had a guy go off the deep end on the TDI thread, email me and even called me at home twice. And all I asked to do was not to post his sales stuff on my thread and he went balistic. I almost quit the TDI forum over that, but the forum moderaters straightened him out.

Larry,

So why the comment about biting your tongue? Couldn't resist saying "something" even if it was a teaser?

This thread is NOT about changing the oil hot & often. That's NOT the only way to make a motor last a long time. What works best for Larry doesn't mean it works best for everyone.

There's more than one way to skin a cat.

Have a great day & lube in peace,

Regards,

And some of us care about things other than just making the engine last a long time. Of course you can get a million miles out of an engine with quality dino oil changed at the correct interval (and proper maintenance in general). Nobody is saying you can't (or that synthetic will make that happen, while dino won't). There are OTHER advantages to synthetic, which some of us like...

Or was that "lube a piece"????

md21722,

Is that not what I said? I basically said I'll do it my way and everyone else can do it theirs. If you want to reword that as there's more than one way to skin a cat, that's still saying what I said? So what is wrong with that?

Have a great day,

Larry's "hot and often" may be the best method of oil change for minimal wear. I don't think anyone can dispute that.

I, personally don't like to change the oil that often, so I use synthetic at a greater interval. It may be about as good as Larry's if the filter is changed between oil changes. But... I don't think the difference is that much to make a fuss over.

It's what works for you and what you are comfortable with.

Now MB coolant is a differnt topic...



BTW

I can't see the connection between chain STRETCH and oil changes.

The idea being that dirty oil wth excess soot, etc causes the chain and sprockets to wear at an accelerated rate, appearing as "stretch". Dino oil must be changed frequently to prevent this and not everyone is as diligent as Larry in that regard. Synthetics are much more forgiving.

Slight wear of the chain rollers, slight wear of the sprocket; but stretch?

With the reasoning above, we should change the sprocket, not the chain.

Why do the chain links elongate? I think this is a question for the chain manufacturers.

They elongate or "stretch" from wear though, they aren't actually being yielded or anything just wear is making the holes a little bigger. After long enough you will not get a perfect 0* even with a new chain because the sprocket will be wore, mine didn't go back to 0*.
