I just got a used 1997 protege
I want to change out all of the fluids

is there anything special about the fluids and weights in general (aluminum anti-freeze I assume)

what weight of gear oil is recommended?

thanks in advance
brant

 

Where in the world are you?

 

good question...
colorado
so 0degree's F to 110 degree's F
I'm really just needing to know if its motor oil (like an old honda I had) or gear oil like I assume...

so probably 75-90 is my guess


another question, I think I know the answer but will ask anyways:
do these motors have hydraulic lifters?
not requiring the zinc of old motors?

 

If it is gear oil, be what I'd put into it. I am not familar with manual Mazda or "newer" transmissions. You will know if it is gear oil. Re-read your first post about the aluminum anti-freeze. That will explain the replies.

 

The manuals typically don't need a fluid change.
The lifters are cups with shims, not hydraulic. I still have to measure mine.
You should buy a copy of the Haynes manual if you do your own maintenance.
Don't add extra zinc to the oil. Learn about engine lubrication at the Motor Oil University here:

I assume you have the 1.5L engine. Could you add your car's data to the signature?

 

I think I fixed my signature
I guess I'll see when I post this

thanks again everyone
it is a 1997 1.5 with a manual transmission

I've got a Haynes manual on order, it just hasn't arrived yet.
and I didn't see the transmission oil wt given in the factory manual.
I want to go through all of the service, fluids, filters, timing belt, water pump, etc before putting this car back on the road

just gathering fluids until the weekend, and want to make sure I get the correct ones.

and I should correct my aluminum antifreeze statement, to: antifreeze safe for aluminum.

 

Thats ok, again if you need to change the tranny oil, as per my post on ignorance, pull the drain plug. You will know if it is gear oil, heavy smelly stuff. As was posted, really shouldn't be a need to change it, if you do, given location, again I'd suggest a multi vis gear oil.

 

I was wrong in an earlier reply:
Haynes says: API GL-5, SAE 75W-90 gear oil, every 30000miles or 24 months.

My gear oilis way way waaayyy overdue. My trouble is I can't get the fill plug unbolted. It does not budge and it will round out or brake.
Maybe I try icing it with a freeze spray and treating it with the best penetrating oil known to mankind: 50% transmission fluid /50% acetone.

I updated the The Unofficial User’s Guide to the ’95 to ’98 Mazda Protégé accordingly.

transmission plugs (on other cars at least) are almost always NPT, or "pipe thread"

that means that they will start turning easier once they break their bond and you have less chance of stripping.

I have Always been successful on other cars using MAP gas or even a small propane bottle to heat the rust and oxidation that is holding it tight.

try that.

 

Thanks brant914!
I finally got it done this morning. I did not have to use any drastic method. A long 15/16th box wrench and tap with a hammer got them loose. The old oil looked good, no worries.
