This is not an uncommon phenomenon...

Several years back � I mistakenly put 5w � 30 in the vanagon

And had the same � off the exit ramp� experience.   I took it to the local
euro-garage which

Reported that once they put the engine back on 20w-50  - the

Oil pressure returned to normal at idle � and sent me on my [ road trip ]
way

I am not sure if this causes/ caused damage but err... 800 miles later...

My engine had a partial meltdown on the Mass Pike.

Forensic analysis by Boston Bob the next summer was inconclusive as to the
cause.

So in the process of replacing the engine � I heard the stories about what
one

Bad fuel injector can do and replaced all of them along with all the coolant
hoses, 

New converter, O2 sensor, exhaust, blah , blah , blah

Replacing all the fuel lines this Saturday... [finally ]

Subject: Re: 20W50 did the trick (10W40 in the winter.)

I'm using 20W50 in mine, but still experience a strange phenomenon...

I don't see the little led come on until after a highway run and then
at idle it flickers...sometimes lights solid, but once RPM's are up it
goes away... 

We just had 'er apart back in February to do the heads and I am told
(someone else did the heads for me...) the hash marks were still on
the cylinder walls...

Could my rings be worn? Bearings? I have had folks say not to worry
since it goes away once you put it under load (RPM up).

Thoughts?
