I am switching the ole ladies minivan over to the rotella diesel oil next change . No more diff, oils .... just gotta figure out how to mary the PSD oil filter to the 3.8 in the van. lol
[/ QUOTE ] wouldnt do that if i was you....i know a guy that did that....all was well for about 10,000....miles then he lost front and rear crank seals...and a few others due to swelling......there are some pretty harsh deturgents..in rotela..add 1 quart once a year with the regular oil to clean up the inside of the engine....my 2 cents
