I'm not high and that $16 bottle of techron has no where near the cleaning
capability of the stuff they feed directly into the rail. I prefer to use
this system though. http://www.motorvac.com/ Average cost is $99 and it
takes about half an hour.

4.0 rear main seal is 2-piece, not one. Tranny does not have to come
off the replace it and it's definitely not a $400 job. Took me 2
hours to change mine - and half od that was getting the old pan gasket
off so the new one would seal. Pay attention to the advice - put a
rag behind the rear of the engine under the valve cover and see if
that's where the "rear main" leak really is. That's a lot more common
than a rear main (mine was over 150k before it really did start to
leak).

I just tried a tank of that Shell 91 octane super crap on a trip and my
engine went insane!

I don't know what is in it, but my manually set up 258 would 'not' run
over 65 mph except on a down hill, I even had to gear down on a couple
long uphill runs, which is unheard of for my rig, even 3rd gear wouldn't
pass 65 mph! (normally 3rd pulls fast up to at least 75 mph)

I also lost about 30% for gas mileage. It made for a long trip home
too.

I finally got it low enough and put in Esso gas and magically my engine
came back alive with it's normal tire chirp off a fast start and top end
power restored.

Hi Mike,
Might put a pressure gauge on your fuel line and see what it is at
full speed. I'm betting zero as it may now not be able to keep with the
more gasoline your engine can burn with higher octane.
