NE1 with experience/comments on engine flush. I know for older cars esp. with a sludge issue it may be helpful to do an oil flush. A buddy swears by it even for newer cars every 20K or so. What say you?
A complete waste of time and money on any car running synthetic oil. Just drain the old and fill the new. If it really was a good idea. Every mechanic would at least do it on his own car. I've never known any mechanic to do it.II kings 9:20 said:NE1 with experience/comments on engine flush. I know for older cars esp. with a sludge issue it may be helpful to do an oil flush.

II kings 9:20 said:What about a 5 year old car that has not had synthetic oil?
FWIW my service dept. said it's OK for me to go on the 6000 mile plan A after I asked specifically. But then I qualify formally: it's not hot or dusty here or extremely cold, my drive to work is over 10 miles mostly on freeway, etc. And the 8 uses synthetic.DanRealtor said:I change my oil every 3,000 miles in my SRT-8. That's about every 25 days. I know it is overkill but since it's part of the dealer service plan, and I want to be damned sure that if I ever do munch a motor, they can't say the car was not properly maintained. As soon as the warranty is up (at 100,000 miles) I'm going to change it every 5,000 miles.
Flush with anything? Not a chance.
Purist? Oh yeah.
Whichever is cheaper.II kings 9:20 said:Good points KJ, I am going to give the ATF some thought guys. Here is one for you: Dexron II or Type F ATF.
Ouch! That little valve got it's world rocked...DanRealtor said:So what if you had a catastrophic engine failure like this:
And then when DCX dissected your old motor they found an unapproved oil additive (tranny fluid from your flush). Then when they deny your warranty claim and try and stick you with the entire bill for the engine replacement, you get to singlehandedly take on DCX. You vs them and their lawyers, fine print, and deep pockets. Don't worry, I am sure in the interest of outstanding customer service they'd just let you slide. (amsoil flashback time).
Best of luck to the "Purists".
