I have the 2.0 engine. I'm at about 2600 miles now and I still haven't bought any fluids to keep with my car (coolant, power steering fluid, etc.). I should probably buy some, but I don't want to end up getting the wrong stuff, and I figured there's no better place to ask. :)

What brands/types of fluids do you guys recommend? I don't know if all of these are applicable and I'm too lazy to check my owners manual (smack me, I know), but: coolant/antifreeze, power steering fluid, brake fluid, and whatever else. I can't imagine windshield washer fluid is a complicated decision, but I can throw that in there too. If there's anything I should know about any of these, or if anybody has suggestions, I'd greatly appreciate it. :)

I will point out right up front having a gallon of antifreeze in the trunk did save my bacon one time so I certainly won't say you don't need or should not carry extra fluids. Of all the fluids you list windshield washer fluid is the most important to carry. All the others are nice to have for peace of mind but on a new car you shouldn't need to worry about non-consumable fluids. But peace of mind is a damn fine thing and I suppose carrying extra fluids is a cheap way to get it. And shit happens.

Anyhoo, P/S fluid is Dexron III ATF, brake fluid is DOT3, coolant is probably FL22 - there will be a sticker on the coolant reservoir next to the cap if so. I know what brands I prefer but I don't believe it matters. If you like and trust a particular brand then carry that - this will maximise the peace of mind dividend.

Oh yeah, I need to know about transmission fluid too, since my car's an AT.

And thank you for the advice.

I don't have an auto so I am not 100% sure what ATF is right. Mazda specs something called M-V or suchlike. There is speculation this is Mercon V, and it may even say Mercon V right on the dipstick. If this is true then you can just get one of the multi-vehicle ATFs offered by Petro-Canada, Castrol, Mobil and presumably others. These fluids are compatible with Dexron III and Mercon V (and numerous other ATFs) so you will only need to carry one bottle to cover both P/S and ATF.

Does anybody else have any advice here? I've read here and there about some stuff regarding "Dexcool" or something. I don't know. I guess I'll figure this stuff out on my own, no big deal, but just checking to see if there's any specific recommendations for our car.

Get Mazda brand FL-22 coolant. Made by Motorcraft. You may use Peak Global-Lifetime as a substitute.

Get Mazda M-V ATX fluid and use for Power Steering and Automatic Transmissions. You may substitute Mobil 1 ATX synthetic which states on the bottle that it can be used for Mazda M5 applications.

Get Motorcraft Synthetic Blend 5-20 if you want the factory motor oil. Or pay extra for a full synthetic such as the new offering by Valvoline, Penzoil platinum, Castrol Syntec, or Mobil 1. etc.. I just get 5qt jugs at wal-mart.

Brake Fluid, Mazda has their own Dot3, but you can get any major brand.

I attached pictures of the fluids Mazda sells at their parts desk if you wanted the Factory recommended products.

As for windshield washing Fluid... Get whatever is on sale. :)

To clarify, if you simply drain the fluid out of the transmission pan and refill it, you need 3 quarts of ATX fluid. To perform a full flush of the transmission fluid (see the how-to stickied at the top of this forum), you need 9 quarts.

Also, Mobil 1 ATF is now listed as being directly compatible with Mazda M-V (which is similar, but not identical, to Mercon V) so you don't have to buy Mazda-branded ATF if you're worried about using proper M-V fluid.

When flushing Transmission fluid, is it just for automatics or do you have to change it in manuals to?
[/quote]

You need to periodically change the fluid in the MTX too, but it's not a "flush" like with the ATX. The MTX requires only about 3 quarts of fluid IIRC, and a drain and fill replaces pretty much all of it. It's as easy as changing the engine oil.

Maybe easier - no filter to change.

Didn't Mazda issue a TSB stating that Mercon-V and M-V were in fact not the same thing and not to substitute?
