like I said, I've been doing it on all types of different motors for years, and it has worked like a charm every time. a tone of grey/black **** ran out of the drain plug.... I changed the filter, re-filled it with fresh oil and its doing fine. she drove from here to New Jersey yesterday and back... and is leaving for Texas in about an hour... she says its still good on oil, and has made absolutely no noises... no overheating issues either.

 

putting some diesel in the oil would have done better or the seafoam with 2 more changes.

 

Actually I used to have a subscription to Consumer Reports and they did a test using a bunch of different motor oils in New York Taxi Cabs and they found no big difference between any of them, even the synthetics......

Here is a copy of the article, I used to have the actual hard copy but I lost it.....

as i was a mechanic for almost 5 years ive seen this several times..and its all women or young girls that mainly live on their own, theres been some that i had to take a screw driver and a hammer and put into the drain plug hole and chisel the hard crust out so it can drain like 140w gear oil in 20 degree weather..

 

Stick to working on MRI machines Colby.

Tranny fluid helps get some of the gunk out...

 

Damn, I must have a dirty mind. I expected a much different discussion after reading the topic of this thread.

 

I imagine a variety of crap you find at the local parts store will "help get some of the gunk out" - however, you won't find me pouring hydraulic fluid into my oil

 

I'm not trying to pick on you, but Hydraulic fluid is OIL. There are a lot more bearings and bushings in a tranny then there are in your motor, think about it

 

Tranny fluid is not you're typical hyd. oil though, like what's found in your floor jack or forklift. Just wanted to clear that up before people dump hyd fluid in their engine and expect carbon to come out. As stated above, tranny fluid has detergents along with friction modifiers in it and IT WILL clean your engine.
