Fluid Rundown - For MY information

Posted July 29, 200618 yr

The Z has just come out of storage this last weekend, alive and seemingly well. Now that it's NOT raining in Chicagoland, it's time to work on some general maintenence.

I know the engine takes 4 3/4 Qts of oil with the filter, and I'm planning on using 10-W30...probably Castrol. Good call or bad call?

The transmission, an automatic, requires per the manual, a DEXRON type gear oil, 5 7/8 Qts worth. Anyone provide a suggestion that won't break the bank, and that I can pick up at the ol parts store? Since the car doesn't see much use, I'm not looking for suggestions like Red Line, which cost more than the car's worth... LOL .

The manual also mentions DOT 3 brake fluid for the master cylinder...do they even make DOT 3 anymore...and if not, does DOT 5 meet the same qualifications? I know there's lots of Zs out there that still STOP so I'm sure someone can give me the answer I seek.

I tried a few searches, but the auto tranny info really was hard to come by, so I decided to just kill 2...err 3 birds with one stone.

Thanks all!

DOT 5 is NOT compatible! Going to DOT 5 would require a complete rebuild of the entire brake system - every single rubber bit replaced, and the metal lines flushed with denatured alcohol.

Dot 3 is still easily available, DOT 4 will work as well. There's no real benefit to DOT 4 though, so DOT 3 (which is generally cheaper) will be fine.

Castrol is fine, as mineral oil goes. Any name brand ATF should work fine.

Don't worry Arne, it's 11:30, I'm not running out in my jams to round up any DOT 5. I wasn't sure that DOT 3 was still available, but now I know...and knowing is half the battle.

Thanks for the info.
