Royal screw up....well almost
 

Heading to the beach today and went out to change the oil. After dumpng the used oil back in to the bottle, I realized I used the oil for my wife's charger 5w20 instead of the 10w30 for mine. A trip to WalMart for new oil again before we head out.

Well at least it was oil....could have been windshield washer fluid.:you:

At least you caught it and this post is about that instead of "Ran the wrong oil and...@#$%&*)(@#$!!"...if ya know what I mean...good catch...:clap:

Once I did the same thing, went back to the auto parts store to get the right oil the fellow suggested before I drainit again I run the motor for a few minutes,let it heat up and then do it. It will purge your system of more crap than just a normal oil change.
Just a thought for next time, ask me how I know there will be a next time.

I had called a friend of mine just after doing this and he said the same thing. Which I had already done, not intentionally already. I always run it for a few minutes after an oil change before driving to get it circulating. I could not believe the difference in the color in the .00001 mile oil change, then again the engine does have 180000+ miles on it.

Viscosity is the resistance of a fluid to flow or deformation. In everyday terms (and for fluids only), we can say that viscosity is "thickness" or "internal friction". So a lower viscosity oil will provide less friction (friction in this case being lubrication quality) than a higher weight oil. So the less friction there is, the easier it is for parts to rub together producing wear. Actually, 5w20 would probably work fine in your engine in the winter time when you want a little thinner viscosity index, but for a high milage engine like yours you're better off with a 10w30 or even a 10w40 for the summer when the additional heat tends to thin out an oil. But remember that with all the additives and different blends in oil these days the oil itself is not actually 5 weight or 40 weight thickness... rather, it gives your engine the lubricating qualitys of a 5 weight or 40 weight or whatever it is that you happen to put into the crankcase. In all cases, good catch on the oil. :clap:

About 12 years ago a buddy of mine got under his car and drained the Tranny fluid and added 5 quarts of oil to the engine. We still laugh about it today.

:clap::clap::clap:

Try that with a diesel. The Duramax is filthy looking the moment you see oil pressure after the oil change. Someone said the Cummins doesn't do that. Glad it turned out. Just another day at the beach..

My old International Scout II had a Diesel engine in it (Nissan 633). Same thing... change the oil, add new, filthy in seconds. High pressure in the combustion chamber forces carbon past the rings and into the crankcase. That's why it's super important to change the oil in a diesel at the proper intervals. (or maybe even a little sooner). :head:
