Re: Transmission and Oil question

["basfe25" <dmcman73@xxxx>]

I've used (and only used) Castrol GTX in a jeep I owned and the 
engine lasted to 250,000 miles (although the tranny didn't keep up). 
Slick 50 is the worst thing to use. Think about it....it has teflon 
particles in it (not blended into the oil but suspended particles). 
What is the job of the oil filter? to remove ANY particles that are 
in the oil to protect the engine. That there is a waste of money 
since you are filtering out all that "protection" that was added to 
it. Any engine will last 200,000+ miles if you take care of it and 
change the oil at the recomended intervals. As for synthetic 
oil...it's ok but you will have a few oil leaks that will spring up 
after putting it in. One of the main places I can think of is the 
seal that is behind the main crank pulley in the front of the 
engine. This is already notorious for leaking with regular oil. 
Synthetics flow nicer then regular oil and that's why it's better 
and that is also why leaks you never had before will appear.

For any transmission stay away from additives. I remember speaking 
to a friend of mine who was a mechaninc and he told me that almost 
all the additives out there for transmission will either rot the 
seals out or casue them to swell up. Just use regular Dextron III 
transmission fluid. Remember if the additives would be better for 
the car and make the parts last longer don't you think that the 
manufacture of the car would put them in so that they could offer 
better warranties or have lower repair rates on warranties?

So to sum it up....Regular Tranny fluid for the transmission and 
either Regular motor oil or Synthetic (your choice) in the 
engine...NO additives! Remember that the synthetic oil MAY FIND a 
leak that has been able to get away with regular oil. I say find and 
not casue becasue synthetics don't casue a leak (like rot out a seal 
or something) but finds an exisitng one that regular oil was not 
able to get through.
