It occurs to me that I ask about viscosity every couple of years or so. I just can't seem to wrap my brain around it.

This mixing of oil was a short term fix only. I've been ignoring the blinking dash light (change oil) for too long. I was certain the risk of low oil outweighed any risk of lubrication reduction for a couple days, so I dumped it in.

There certainly seems to be something to this polymer shearing, as the pressure came up slightly after changing the oil.

It seems that even the simple tasks can teach us things. My first time changing oil on the lift: I've always been on the ground with jackstands. My nice clean oil catch can with the telescoping neck and oversized funnel, I figured this was going to be the easiest, cleanest oil change ever.

Nope.

Had the lift high enough to not have to duck (I'm six foot) and totally underestimated the initial lateral velocity of the oil stream...

SKEET

Right on my reasonable presentable boot.

Well, it WAS reasonably presentable.

I grabbed the oil catch funnel and repositioned it, but then it started dripping, and the funnel wasn't big enough to catch both streams..

Anyway, sufficient to say it made a mess.

But it's all done, the boot will never be the same, but the pressure is slightly up, and the slight lifter tick at start up went away.

Changing oil... Good idea for everything but your boots.
