how many miles do you have on the car. for the most part it is a scam. essentialy its gassaline or some simmalar solvent put in the oil and allowed to run for a while. its suposed to break up sludge and contaminants that way when you drain the oil in 10-15 min it will come out in the oil. dont need it on low milage cars and harmfull on high milage cars. high milage it might block an oil passage and ive also seen oil leaks start, not that its breaking down the oil seals its more of all the crud thats blocking the oil leak.

Whenever a dealer recommends something that the owners manual doesn't, it's because they want your money. What a novel idea. Dilute your oil with a solvent and then run the car for a few minutes with diluted oil. You will not have sludge in this motor if you've been using a good synthetic and/or changing your oil at regular intervals.

They may be thinking of something different, or maybe I just am. But an oil flush to me can also mean running oil through your car starting it let it sit for a bit. Then putting new oil in your car and starting it .... And so forth. Basically add new, run, add new, run, add new.

Now ive never done this, but ive heard of it.

They used to sell this crap as an additive in stores (still might for all I know). The idea was that you bought it, dumped it in the car, drove around for a little while (gently) while it dissolved deposits in the engine and then went straight to get an oil change.
Use quality oil and change it regularly as some of the guys already said.

Using Seafoam in my oil and have my turbo go out 6 months later after running perfectly for 3 years may have been a coincidence but it put a bad taste in my mouth... Flushing with oil sounds like it could be a good idea but I wouldn't think it'd be $100 worth of service.

Never, ever do an engine flush on a turbo engine...actually to no engine at all... (no)

It's a pure profit center for the dealership. Period.

thats what i figured but anyway i only have 15K on the car and change the oil with mobil 1 every 3K

You're fine. No flushing needed. If you have to flush a car that new, you've got more problems to worry about (like finding out why there's so much sludge in there). I tore down a Nissan motor with 165k miles that I had run Mobil 1 in for the last 75k miles of those 165k miles and there was very little sludge buildup at all. Of course it wasn't a turbocharged motor though.

i remember reading an article on mobil 1 where they dissasembled a mercedes engine after 100,000 miles after that no sludge and minamal wear infact some of the parts looked new. all that was done is mobil one oil changed every 3,00 miles. also look at how many high performance cars come with mobil one from the manufactuer

Only 15k miles and they wanted to do a oil flush..What a bunch of A-holes...They dont care about you,they just want your money.

I just bought amsoil synthetic oil for my speed and the rep gave me a bottle of the engine flush to use when I switch over to synthetic. He said it's best to flush when you're changing from regular to synthetic. But 100 is ridiculous! The bottle probably costs like 5 bucks and you only run it in the car for like 10mins. This guy at amsoil really knows his stuff so I'm convinced on his methods.

Why would you need to flush the old oil out since Amsoil is compatible with dino oil...? If you're looking to get rid of all the dino oil, that will happen on your second oil change using synthetic. I personally don't agree with the whole flushing thing. What exactly are you looking to flush? The engine is new, there are no deposits or sludge accumulated yet...

I guess I'm just not understanding the need for a flush on a new car... (huh)

It also wasn't a Mazda, nor was it direct-injection either I'm sure. If you have seen the pictures that are out there of the internals (which, I'm assuming you haven't based on your "no flushing needed" comment), we get sludge on the DISI very quickly - TOO quickly. I would seafoam the engine on your own for cheap! It's definitely a must (plus a catch-can to help eliminate accumulation of sludge in the IM/top end).

How does flushing the oil help get the sludge out of the intake manifold...? (huh)
Unless you've seen a Mazda DISI engine taken apart first hand, I wouldn't comment on seafoaming your engine. Everything on the net should be taken with a grain of salt. Those pictures you talk about, no one knows for sure how that engine was maintained and what kind of operating conditions its been through. Yes, I will agree that these engines have the potential to accumulate/create sludge, but I'm not going to state that until I myself take apart my own engine and see it first hand.

Seafoam at your own risk!!!! (braindead

If you use a high quality engine oil, you should be fine at least for the next 75,000 miles of your engine life; if properly maintained.

That's what I thought that since the engine is new there really shouldn't be any build up. The guess the amsoil guy just wanted to make sure I was running his oil to 100% efficiency.
