i was just reading on some forms and they are using Gear Oil in the transmission I have a 91' Protoge LX 1.8L Auto any Ideas????

 

For manual transmissions that's exactly what they should be using; for automatic transmission equipped cars like yours, gear oil would bring about a quick and expensive death to the transmission.

 

thanks for the reply im new to owning a 4 cylinder all my other vehicles are V-8"s

 

Doing a Oil change and engine flush, What kind of Engine oil would anyone recommend im thinking 10w30 but its got almost 200,000kms Any Ideas????

 

There is no difference between 4-cyl and 8-cyl cars as far as fluid types. Now the specifics of what's used may vary from one manufacturer to another but an automatic requires automatic trans fluid (ATF.)

For engine oil, use what the manufacturer recommends (owners manual, under hood decals, the oil filler cap, repair manuals, etc)... even w/200,000kms on it. If they want it to use 10w-30 then use it. If they want 5w-20 then use that. You should not deviate just because the car has a few miles on it. That's an old wives tale.
Remember, it's the second number (15, 20, 30, 40, 50) *EDIT* not the first (0, 5, 10, 20,) that determines the viscosity of the fluid. THAT is the most important number for any given engine builder/designer.

 

What virgin1 said and skip the flush; that'll save you money and your car won't know the difference.

 

Thanks guys i skipped the flush and just went with the 10w30 Penzoil This car was about to get crushed b/c its 20yrs old. The dealership said it was owned only by a old lady so i bought it for 300.00 and to my surprised it drives and runs amazing & I got 350 kms on half a tank-($25) I'm Just looking for any tips I've never owned a Mazda(Imports) I have only worked on domestic vehicles.
