GM Dealers Oil brand?

[NewbieZ71]

Had my 7500 service done last week and had dealer change to synthetic engine oil w/AC filter.  Did check on the brand of filter but forgot to ask what brand synthetic they use.  Do all GMC truck dealers use the same brand filters and oil?  If so, what oil?  They changed out the fluid to the blue stuff to get rid of the "clunk" seems to have worked.  Had them check the rear window wind noise but they "couldnt duplidate".  Everything else was great.....

My experiacne is that i could be one of three types.

1.Moble One-If they used M1, then your oil change would have cost like ?-?.

2. Ouaker State-

3. Valvoline

Thats what my dealer goes in between. I know GM uses Quaker State as the factory fill(except for corvette).

I would call them and ask, as its not good to mix two types of synthetics.

When I bought the truck they gave me the Quaker State oil guarantee so it would make sense that they would use that brand...however, maing sense doesnt seem to be a big deal when it comes to service departments now does it!? I shouldnt complain because I have had a great experience with them......I havent read any bad comments on the Quaker State synth product have you?

I haven't read anything bad about synth products at all. In fact, next vehicle i buy i'm going to switch to Moble One onthe first change. I've heard its good to use regular oil to properly "set" the engine.

I would call the dealer ship and confirm the oil they used though. Just so you know.

Why are you going to use Mobil 1?  I wouldn't even consider using any of their products.  You should look into using Amsoil, and not just in the engine.

I have been reading, I think over at PUTC, that Castrol is being accused of not being a true synthetic but advertising that they are.  Something about the base is modified natural or vegetable oil or something and not full synthetic.  People are P.O'd and saying they were had.

I haven't had to change the oil in my truck yet but I will change to Mobil 1 TriSynthetic and a Mobile 1 filter. Every vehicle I own has Mobil 1 in it. I really believe it extends that life of the motor by reducing wear and tear.

Yea, Frank told me about that on the phone. I might try that instead. First if have to get a new vehicle :biggrin:

Called the dealer and they use Quaker State so that the QS warranty is good to go...guess it would be kinda dumb for them to use the QS warranty as a sales tool and then force buyers to go elsehwere for service becuase they cont use the product... any comments or links to a review of the Quaker State synth's?

I get free oil/filter lube at my dealer every 3000 miles. I asked about synthetic changes and was told that I would just have to pay the difference between the 2 changes. So guess how much the dealer wants for a mobil-1 oil change?

 

$65.00 (regular oil change is $20, so i would have to pay them $45)

 

Guess I'll be bringing my oil to them

$45??? HOLY SMOKES

 

A case of mobil 1 at kmart is $26 (plus i get 10% discount from my gf)

 

What a RIPPPPPP OFFF
