Engine Performance problem
1991 Dodge Dynasty 6 cyl Front Wheel Drive Automatic 112000 miles
I've just gone over some information on oil and oil filters. From what I've determined from the data is that a Mobile1 oil filter is best for filtration and Havoline followed by Exxon conventional oils are best based on the numbers in the table.
The filter choice sounds correct, but the oils and how they ranked did not, maybe I'm wrong.
Do you have a suggestion for a good conventional oil to use that will clean deposits and sludge that have developed in this engine over the last 18 years? It runs great (now) and it just doesn't seem to me that the previous owner took much stock in maintenance and I would like to try to reverse some of the build-up I suspect may be in there.
Also, do you suggest that I change the oil every 1,000 miles for a few times?
Sorry to have rambled. I look forward to your response!
