I'm not an expert in capilary motion. That's interesting though. Have you figured out what it is? Better question--can I put regular (5W30) in my motor after I've put in synthetic? Someone tld me I shouldn't do that.



Yes I think that's true because 4 deg C is the most dense that H20 gets. I don't understand what you mean about higher temperatures sucking oxygen out of the atmosphere though. How does that work?


To create heat takes oxygen.

Since you're the expert on capillary action explain this one to me...
In both my car and my snow blower....if I have synthetic oil, if I check the oil in the morning after the engine has been off overnight the oil shows about one inch or more overfull...I wipe the dip stick and check it again it's right on the mark
some type of Capillary action ...right?
Why doesn't it do that with standard 5 - 30 motor oil??

Surface tension. Synthetic is excellent with a really low rating. (Dyne I think?). The lower the surface tension the oil has the less drag it creates on an engine but still meeting the high/low W temp rating and viscosity to meet today's high revving fuel efficient engines needs.

I'm Pedro de la Pradera and I use Royal Purple in my muscle cars and truck.

The strangest thing is I used to put synthetic in my old truck and it never did that...the only reason I did one oil change in my car and snowblower was as a test.
Starting to think It's the metal now used in the dip stick "aluminum" ....they used to be made of steel.

For combustion, perhaps. The sun is a fusion reactor--no oxygen used. Not much anyway. Mostly hydrogen fused to helium. Actually everything that isn't absolute zero gives off heat through infrared radiation.


Absolutely, I got off on a bit of a tangent, answering what I thought was a hypothetical question.

Yes I recall you posted something of that nature before. Stellar mechnaics are a little over my head though.

Over yer head! that's a good one, yer probably reclining under some right now. Look up of course they'er over your head. It's not stellar mechanics anymore Zip or Zipper, what did mum call you? It's electric like your toaster, phone, lights That is only my opinoin, I do not have the capital to build a suitable lab to prove ah my opinion. Everything is electric and if it isn't we don't need it. Strong studf runs everything the same way, around and around.

hot damn! The U.S. Department of Defense - 2014 Climate Change Adaptation Roadmap... say what? For a "cooling world"... say what?

The responsibility of the Department of Defense is the security of our country. That requires thinking ahead and planning for a wide range of contingencies.

Among the future trends that will impact our national security is climate change. Rising global temperatures, changing precipitation patterns, climbing sea levels, and more extreme weather events will intensify the challenges of global instability, hunger, poverty, and conflict. They will likely lead to food and water shortages, pandemic disease, disputes over refugees and resources, and destruction by natural disasters in regions across the globe.

In our defense strategy, we refer to climate change as a “threat multiplier” because it has the potential to exacerbate many of the challenges we are dealing with today – from infectious disease to terrorism. We are already beginning to see some of these impacts.

A changing climate will have real impacts on our military and the way it executes its missions. The military could be called upon more often to support civil authorities, and provide humanitarian assistance and disaster relief in the face of more frequent and more intense natural disasters. Our coastal installations are vulnerable to rising sea levels and increased flooding, while droughts, wildfires, and more extreme temperatures could threaten many of our training activities. Our supply chains could be impacted, and we will need to ensure our critical equipment works under more extreme weather conditions. Weather has always affected military operations, and as the climate changes, the way we execute operations may be altered or constrained.

hey Walter... buddy... that's 2 of your reddies but you won't touch my replies... why so Walter, why so? :mrgreen:


hey petrOCD, try the following from the PAGES 2K metadata summary... 30 ice cores - YOU'RE WELCOME! :lol:





petrOCD, clearly the point went over your miniscule comprehension abilities... Walter's "still cooling" reference (and the denialsphere's accompanying play on that study) is to imply "GLOBAL cooling". My point was to question the rationale (Walter's C&P rationale) in attempting to equate a single study's summer period localized Northern Scandinavian results to the collection of historical annual reconstructions.


ooops! Forgot to provide a link to the PAGES 2K metadata worksheet... here you go petros: www.nature.com/ngeo/journal/v6/n5/extref/ngeo1797-s2.xlsx

standard Locutus CPR (Cut & Paste & Run)... and you're back to the misinforming Goddard! Oh my... Hey Walter, do you ever, ever, ever check anything out... or do you just blindly accept any ole Locutus CPR? Here Walter, have a dose of reality... remember Walter, misinforming Goddard/Locutus are drawing reference to sea-ice extent:






You missed the part where we were speaking of the whole world not just the Arctic. You've been flirting too much with Petros.

the Locutus linked reference is with respect to Arctic sea-ice extent. And of course, you simply accepted it, lock-step! As I said Walter, do you ever, ever, ever, check anything out yourself?
