Did you flush them both out completely, or was there a little Dino left in one of them? You can't mix the red fluid with the green you know?

 

AHH thats it!!

 

I have always wondered why my blinkers were so loud...never done changed my blinker fluid.

 

You might want to engage the services of one of those oil testing outfits for your testing, so you can quantify the matter. We change our motor oil as often as we do due to the contaminant load it's carrying rather than some organic decomposition of the oil itself. The oil's black when we drain it from the microscopic particles of ash that have got past the rings and which are small enough to pass right through the filter, the detergent additive is carrying water around, the sulfur in suspension in the oil is reacting with that water to make sulfuric acid... it's ugly soup.

You can (or at least might) get further between oil changes with a bypass oil filter, either the sort used on diesels or even a Frantz "toilet paper" filter. (You don't need the chemicals diesels need, BTW.) My idiot father bought a used Winnebago way back when that had a Frantz filter on it, and even pushing that big box of a rig around the oil that came out of the 318 was much cleaner looking than the stuff that came out of the 318 that originally came in my Coronet. The drained oil looked pretty close to new, but the TP roll that came out of the Frantz unit was black.

I don't know why I haven't thought of Frantz filters in so many years... I might just plumb one in for the giggle factor if for no other reason.

 

Good idea there, never thought of going to a by pass oil filter.

 

at least once every 300k miles, you should pull the drive shaft(s), and exchange the air inside of them.. they become stale and corrosive.. do this by dunking them in water, ensuring they are completely submerged for at least ten-fifteen seconds..

by following this simple procedure, you've ensured your shafts will last you the life of the vehicle, and possibly until the Mayan prophecies come to fruition..

 

Lmao!

 

Very nicely put. And I agree, now that I thought about it. However, that's for our older engines and older as you have stated. Not the same case with the newer engines, and of course I don't want to get into the environmental impact on changing oil every 3K for no reason.

 

Do you guys rotate the air in your tires every oil change, or every other?

 

I replace mine. Recycle the old air though. It's more environmentally responsible.
