Motul Brake Fluid void's warranty?

[Macaro]

Hello,

I'm a recent ZL1 owner and I called a few dealerships today to arrange my first oil change and service. I have already tracked the car twice and I'm excited to track it again in about a month (hurry up and melt snow...) anyway in the service i want to replace the stock brake fluid with Motul because I've read so many positive comments about the fluid.

On one of my dealer calls, the service guy was a bit of a jerk, in any case he told me the price for a brake fluid flush but said he would not use anything but OEM fluid and that using Motul would void my warranty.

Is he right?

Oddly, the second dealer I called didn't refuse to do the service, they only said that I would have to bring the fluid myself.

Bonus second question...what's the difference between Motul 600 and Motul 660? Isn't higher better? Oh, and finally anyone know how much fluid one needs for a complete flush on the (2014) ZL1?

Thank you all,

Your dealer is a idoit.

They should only charge around $85 for the full flush if you bring your own fluid.

You only need 3 bottles of Motul to do the flush.

Motul 660 has a lower wet boling point. Thats why we use 600.

I would not fight your dealers....just find one that knows what it's doing.

When dealing with a GM service center, they are required by GM to use GM certified parts when working on a car that is still under warranty. If they do sell aftermarket products those parts are certified by GM to be used on a in warranty car. Most dealers use this as a rule of thumb. Some dealers are Performance dealers and have performance products available that are certified for you vehicle. again only if they are working on an in warranty car. If your car is out of warranty they don't care what parts they sell you. The first dealer you spoke do is absolute about this policy. The second dealer will use the fluid as long as you provide it he will not sell it to you. The fluid is fine and I am not saying anything about it. But the catch is in your service records it will say owner supplied brake fluid, if the brakes fail its not GM's responsibility. Look for a Chevy Performance Dealer they know more about these cars than a local Chevy dealer...Good luck with your car!!!

The thing I find hilarious is how many owners of cars do any of us personally know that have had a car fail by changing brake fluid? The same supposed "failure" can occur with normal factory spec'd brake fluid. I agree the performance oriented dealers are much easier to deal with.

From Motul
Motul 600 Extremely high dry boiling point 594F(312C) helps prevent vapor lock and brake fade during hard use, with excellent recovery time. Wet boiling point 401F(205C).

Motul 660 Very high dry boiling point of 617F (325C) and a wet boiling point of 400F

1 degree difference between the two in wet boiling point, but 23 degree difference between the two in dry boiling point.

Is that 1 degree difference really worth the 23 degree difference on the other end?

Just curious, as these are things I am just starting to look at. Never thought I would track my Z, but Ive seen I will never test it capabilities if I don't. So this is all new to me.

I have boiled both motul products...castrol only for me.

Is there a listing somewhere that tells which dealers are performance dealers and which are not? I do recall reading that to service the ZL1 they had to have a special certification but when I asked both dealers I spoke with today neither really had anything specific to say about that.

If the customer supplied fluid meets GM's specifications, it is GM's responsibility from an original warranty standpoint. Not necessarily from that individual service (so if the brakes fail under warranty, still covered. If the fluid goes bad quickly, not covered). GM specifies DOT 3 and not to use DOT 5. Dot 4 exceeds DOT 3, so all should be set.

From what I've been repeatedly told, the 660 absorbs moisture quickly. So, you are at the wet numbers much more quickly, and really should change it out every 6 months or less, where as the 600 is still usable for street driving for a while

again curious,

castrol dot 4 brake fluid 311 wet and 509 dry boiling points, why would castrol work better than motul?

Thank you, new question, are you guys replacing break fluid every time you track your car?

What warranty are you worried about voiding?

The factory warranty...3/36

These dealers are jerks. If they happened to run out of the genuine GM brake fluid when servicing your car they would not hesitate to have their parts runner head down to the local NAPA or whatever parts store and bring back some aftermarket fluid so they can get the job done.

If you're getting water in your system quickly, you've got other problems.
