Default Oil Flush Idea

I have an Idea, and I want to know if this might/will have any negative consequences for my WRX engine.

I run Mobil One in my WRX. Switched at 18k. I do my own oil changes, yet I have this one random slip for a free oil change at a subaru dealership. I was thinking about using it, driving directly back to my house (1 mile, literally), and then draining the conventional and doing another oil change with Mobil 1. The idea being to flush the oil system of my rex. I would also use a new filter (duh).

Good Idea?/ Bad Idea?/ DIAF?

Well yeah, that would be a nice alternative, but I doubt it highly, so I came up with this scheme so that you could flame me.....

Any other opinions?

Other than 2 dry starts within the matter of a mile, it wouldn't hurt anything. I used to drain and replace just the oil, run the engine, then do a full change on my old Ford every other time - kept the motor clean as a whistle.

Just take Mobil 1 with you and have them change the oil for you. People do it all the time.

I don't think it's a bad idea at all. I'd put more than 1 mile on it. Put some seafoam in your car before you go, they'll drain and refill it, then you run it home and change it again.

Give it a try.

Why waste perfectly good motor oil? At least run it for the minimum of 3k miles or 3 months. Also, remember there is no such thing as free lunch

doesnt sound to bad, i would go to autozone and get the lucas crap you put in so its not to hard of a try start on the motor. or go to jiffy lube and get a full throttle engine treatment, that stuff works good. (work at jiffy lube represent.)

Have any of you freeloaders heard of the ongoing oil crisis on the planet!? What a waste of oil. I'm not a big tree-hugger or anything, I never intend to buy an electric car, blah blah blah, but this is an example of a really stupid idea. It is a fact that this world will run out of oil in my child's lifetime, and I'm only 26. Now I can hope for her sake that the powers that be come up with a good substitute by then (science is an amazing thing), but to have you waste it for the satisfaction supposedly cleaning out your engine is ridiculous.

BTW, it's not going to do anything for your engine. Consider this. If your car has a bunch of mud caked on the rocker panels, does pouring a couple gallons of water on that mud remove it? No. If you can't see out your windshield, would just squirting washer fluid on it work? No, you have to wipe that off. Any deposits on your engine (which are few if any) are not going to be rinsed away by 4-5 quarts of anything sloshing around in there for a mile.

First, it's not like "pouring... water", it's closer to a pressure wash. Second, oil contains detergents. Third, it was a "fact" that we would run out of oil in my parents lifetime. Yes, it does clean the insides. However, like I said before, I wouldn't change the filter, I would drain the old oil and just pour about 3 quarts in and let it idle for a while before draining.

Yea. It's just like a pressure washer, and don't forget the detergents. Let me change my analogy to fit yours. Try washing your car with soapy water (i.e. your detergents) with a 40 psi pressure washer and see how clean it gets. The whole thing is stupid. By the way, take it from an engineer that designs pressure washer pumps, it won't clean anything!

Are you trying to tell me that we aren't going to run out of oil? Do you understand the world economy and the scale that formerly third world countries are expanding? Check out the price of either oil or steel, and look back at who was buying most of that 10 years ago. China and India are booming in both businesses now, that's why my gasoline prices have more than doubled in the 10 years I've even been driving.

Back to the point. Don't waste perfectly good oil. What do you think is in there that's so dangerous; rocks!? Modern oils and their counterpart filters clean plenty enough stuff out of there for your engine to last for more than a decade. If you prefer Mobil 1, spend the 30 minutes and do it yourself. Let someone else use the oil at the dealership.

Save it for the people that need to hear it. I put an average of 12-15 thousand miles on my oil before I change it and I use synthetic. Why don't you start a campaign to de-mystify the 3k oil change interval(which is complete bull).

Do you car pool? Do you recycle your oil? Do you keep your cars in peak running condition?

I'm not a freeloader. Go preach to someone else.

The detergent qualities of synthetics (like Mobil-1) are superior to conventional oils - I really don't think you would gain anything from the procedure. Plus, if you have been using Mobil-1 for a while, I sort of doubt there is even any buildup to remove - certainly nothing a conventional oil with it's additive package is going to touch.

Complete waste! As already mentioned, take your M1 to the dealer with you and have them put it in.

Seems like more of a waste of time than resources . I mean why wait for them to put a crappy mystery oil in you beloved car when you can just keep in on schedule with the good stuff ? Plus just switch to AMSOIL , protects better than M1 and you can go longer between services .
