2016 CX-5 seems to be sluggish after recent oil change

[txt990]

For cleaning the fuel system and especially the injectors I think that Techron is considered about the best so it's probably what the dealer might use.

As far as the throttle body, I don't know how to tell how necessary it is. I might guess that the environment the engine is run in might be a factor. I think when there is enough build up around the butterfly flap valve to affect it's operation the cleaning is a good thing.

The dealer was quoting me around $75 for the throttle body service.

I went there this morning. I told them about the spark plugs and to check to make sure all of them are installed properly and connections are good. They took them out in front of me and carefully put them in again. They didn't complain about the plugs.

I told the service advisor I changed those plugs at 75k and it's too soon to recommend plugs. He asked whether I used Mazda plugs. I told I used the NGKs that are recommended for the car. He just kept quiet. Not much to say. They said everything seemed fine.

You missed a golden opportunity to call them out on their scam attempt.
If they pulled the plugs out in front of you, that was when you should have taken out the pic they sent you and showed them that they weren't the same.
After showing you pics of really bad plugs, and then telling you now that everything seemed fine, tells me everything. I would have loved to see them explain it.
You have been too easy on these guys.

I can hear it now.

Oh sir, we are SO sorry!

Somehow our tech got the pics mixed up on his phone and we sent you the wrong pics. It seems that your pics were accidentally deleted, so we can't show you those.

But listen, the next time you need it, how's a free oil change and tire rotation sound? You know, just to try and make it up to you?

Good, when can we schedule you in?

I went there this morning, and they said the oil was a little over the max but nothing to worry about. I told them about the spark plugs and to check to make sure all of them are installed properly and connections are good. They took them out in front of me and carefully put them in again. They didn't complain about the plugs.

I told the service advisor I changed those plugs at 75k and it's too soon to recommend plugs. He asked whether I used Mazda plugs. I told I used the NGKs that are recommended for the car. He just kept quiet. Not much to say. They said everything seemed fine.

He said we recommended you the throttle body cleaning and fuel system cleaning and you declined.

Can I just use some chevron Techron for the fuel system cleaning?

Oh man! You chickened out?

I was REALLY looking forward to hearing about your dealership trying to explain those spark plug pics.

I had to attend a meeting after that so just too many things going on.

You shouldn't need to use techron often. I run it once a year, just to keep the injector tip clean. Many people recommend filling the tank, add the techron, then run the tank down. THEN change your oil. The idea is that some techron gets in the crankcase, and thins out the oil.

I wouldn't use stabil to clean things up. It's almost all 'pale oil'. That can help keep the lighter fractions of gasoline from separating, but won't clean anything.

I read on Techron's site, that to use it about every oil change if you don't use top tier gas. I'll try it shortly and then in another six months.
