um...oil burns hotter and this (what Marchall suggests) acts as a type of
Italian tune-up?

My memory decieved me, it was not 10w oil it was 10w 30.

Well, Diesel Purge isn't very potent if you run it
through in a tank of
fuel (even two bottles in a tank). It was designed to be
run through the
engine straight (disconnecting the hoses and running on
JUST DP with the
supply and return hoses in the DP bottle). If the engine
starts
instantly sometimes and take several turns sometimes, then
fuel is slow
getting to the engine properly. That could be the injection
pump
misbehaving (not likely, but possible) or an injector or
two that are
less then optimal. It COULD be several other things too,
but a really
clean engine running on synthetic oil seldom behaves this
way except
from a fuel problem. If you use conventional oil, then
I'd recommend
that you change to synthetic and see if that makes a
difference
especially in how fast the engine cranks over and starts.
This will take
many thousands of miles for all the benefits to max out,
but it's
improved every one of my engines more then ANY other thing
I've ever
done to them (other the replacing BROKEN parts or
connecting things that
were disconnected or plugged up).
There is ONE final CHEAP trick I use when nothing else
seems to work
(and it DOES work more the 50% of the time) and I've
run out of
inexpensive ideas. Put a qt of 10W30 conventional motor oil
in the fuel
tank and drive the car (hard at least a little of the
time). The engine
should seem quite smooth, but ever slightly lower in power
with the oil
in the fuel. When the tank is nearly empty refill with just
#2 and see
if the engine doesn't have more power and is smoother
then before and
usually starts faster?
