[wwh975]

I just read some of the threads that said that STP fuel system cleaners would cause the dreaded sludge problem. Is this true? It hought the cleaner helped clean all the parts. THanks.

Hi,

I have been hearing alot of bad things about this oil sludge, I just bought a used 98 Durango with like 92K miles on it, and this is starting to trouble me, is there anyway to eliminate any kind of sludge already built in the engine by previous owners? I cant undo what they did but wouldnt want to have to pay for their careless maintenance. Thanks in advance for the help.

synthetic oil isn't necessararily better than regualar oil. I asked a mechanic about it and he said synthetic is only better if you don't plan on changing it every 3000. Synthetic simply doesn't break down as fast as conventional oil and it doesn't reduce friction any better than a good conventional changed regularly. That's what I heard anyway.

To remove sludge you just need to buy some engine flush. You can find it at any auto parts place. You drain the oil, add the flush which is solvent based, run the engine, the drain the dirty flushing solvent and refill with oil.
