I recall on the synthetic oil thread a while back that it is advisable to do
an engine flush first to clean it out like for example to remove one quart
of oil and add one quart of Marvel Mystery oil and run it for about 300
miles then change filter and oil. This is what I did and it seems to be
working OK.
In my case I did the 5 minute engine flush first with Gunk Engine flush then
ran Marvel for 300 miles with new oil before I switched to synthetic. If you
do the engine flush just follow directions on the can.
If you do a flush follow Stan Wilder's advice and filter the oil using a
white coffee filter after it settles to see what crud came out and/or use a
magnet to see if any metal is in the residue. Filter only the last 1/2 cup
of oil dregs after mixing 50/50 with gasoline. Remember to capture the oil
in a clean can to get pure results. Do the filter thing with the 5 minute
flush and also with the marvel oil run.

properties. On an older engine, switching to synthetic can break down
deposits in the engine, clogging the oil filter causing loss of the engine
in a short time due to oil starvation.
