Just a couple questions

[haux]

I got an oil change a few days ago.

Of course, the guy doing the work tried to upsell other services.

In the process, he asked me if I had ever used ran fuel treatment through the brake booster hose. I told him I had done Seafoam before and he cringed. I've never heard of using fuel treatment/fuel injector cleaner in this manner. Have any of your heard of or done this?

Also, he asked me if I knew I that I had transmission fluid in my power steering system. I said yes, and that Toyota's official documents specify that. He went on to say that they (this business) never do that and that they recommend synthetic power steering fluid. Is synthetic PS fluid any better than the power steering fluid Toyota recommends?

A good many people have put 6-8 oz. of Seaform into the intake manifold via the brake booster hose, including me on one vehicle. The claim is that, when following specific instructions, it will liquify the black oil/carbon deposits in the intake manifold, throttle body, and tops of pistons, to reduce current problems or reduce the chances for future problems. So if your intake manifold is pretty dirty, this process actually does work. But a 10 year old vehicle with nearly 350,000 miles on it, I don't think you do a lot of back n' forth town runs, but rather mostly highway, so I would think you may not have a need to do anything like this.

I would recommend to use the fluid the manufacture specifies in power steering systems.

I think the person who was talking to you was trying to impress you by what he all knows about vehicles.

I've used Seafoam.

My question was, has anyone here heard of using regular fuel treatment/injector cleaner in this manner? For example, the Valvoline stuff you can buy at any auto store. This is the type of thing he was talking about. I've never heard of people running THAT through the brake booster hose.

Sorry, my bad. Misunderstood you. I've only heard of SeaFoam through the brake booster vacuum line, nothing else.

Hopefully you didn't let him do that But it sounds like you are a wise Toyota owner indeed, and omitted (rightfully so) to following this particular gentlemen's advice. Next time tell the guy that transmission fluid is WAYY better than power steering fluid. There is a reason it's used there. Keep this in mind: Some higher end cars used transmission fluid rather than power steering fluid. Transmission fluid has a higher temperature AND pressure rating than power steering fluid. So yeah, Toyota recommends it for a reason Toyota Recommends DEX III for PS fluid...

Running Seafoam thru the brake booster line is something I've seen done on this forum very often Although I would not trust someone else to do it (Hell, I don't even let someone else change my oil, I'm paranoid like that)

EDIT: I've never really heard of anyone running the Chevron or Valvoline or whatever you wanna call it in the brake booster line... I guess it could work... I would stick to Seafoam in the Brake Booster Line thought...

That's what I thought... it sounded very strange and unusual to me.

I'd be changing the oil myself if I was at home. I never look forward to the various services they try to sell me in the process.

+1

though i heard of some people using distilled water to clean off carbon, never tried water myself (only sea foam) that way.
