Without an oil sample, this is all mechanical theoretical masturbation.



I run Mobil 1. I will not run dino oil through a turbo. I change it every 6-7k, before the turbo, every 10k. I don't baby my truck.

 

 

Heres some dino oil for you all in a 318.

 

That obviously would have never happened if the oil was changed at the correct intervals.

 

exactly

 

As a guy whose experience with Chrysler engines predates the small block Magnum and/or synthetic motor oils, I've never seen anything like that in any engine that's seen regular oil changes at 6,000 or fewer miles. I must admit, though, that my professional wrench experience was limited to a racing shop and even then as the electrical engineer rather than the guru mechanic. Still, I would think that if anything like that showed up I would have heard the noise and wandered over for a look.

I could be wrong, but everything I've ever owned including a '68 318, a (wickedly built) '69 440, and an AMC 360 that went 360,000 miles has been run with Valvoline dino oil and I've seen no signs of excessive sludge. My current '98 360 hasn't thrown any clots during regular oil changes but I'll surely check in here if it does next week or any time thereafter.

I honestly believe that those who swear by syn oils in our engines would also swear by things that science cannot prove. But, ya know, live like ya wanna live. It's a free country baby.

 

Ive always used Valvoline dino and fram filters... Regular oil changes at 4000mi intervals and its clean enough to eat off of.

 

I've seen engines in worse shape than that even. The use of Penzoil paraffin based motor oils were notorious for building up solid to the point of filling the entire valve cover with wax and sludge buildup as well as the lifter valley.

sorta like folks who believe in Sasquatch always believe in alien abductions too? too funny..

I'm a believer in dino oil in these engines at this point.. not from experience, but from what I've been told by folks who know a heckuva lot more about it than me and have nothing to gain by telling me that, and reading their proofs and reasoning's for such agrees.

 

I read an article a few years back and they tested several different oils (dino and syn) and then after a few months they torn down each engine and checked out the carnage. The conclusion was that it DIDN'T matter what type of oil you ran. They concluded that checking the oil level consistantly was far more important. Of course this makes sense, because a truck without the proper oil amount is like a human losing a whole bunch of blood.

That being said, this is my opinion: Run whatever oil you want. Just make sure you change it every 3000 miles, and make sure you have ENOUGH oil to lubricate the engine!
