Hello all, I just bought a 1998 camaro v6 3.8 5-spdwith 109K. I plan on changinga few fluids this weekend. Including trans., rear end, and theengine oil. I need to know exactly what is the factory weight oils are required for these (mainly rear end and trans). Please inform me of these. Also, is it very hard to changethe trans and rear end fluid?

 

I don't know off the top of my head

But the auto parts store will

 

Differential fluid- 85w90

If you have a Limited Slip Differential then you need the GM additive from the Chevy dealer. I think you only need one 2oz bottle, but if your rear end is making noise then it would be best to use a higher weight like 85w140 and two bottles of the additive. I changed my differential fluid the other weekend, and used about a bottle and a half of Lucas 85w140 which comes in 32oz bottles. This fluid change is very simple, and also requires a pump to pump out the old fluid. There is no need to take off the differential cover, and there is a plug on the top on the differential on the passenger side of the car. Just pump out the old fluid and pump in the new. Also be sure to use PTFE Thread Seal Tape on the threading of the plug before you put it back on. I reccommend using conventional differential oil solely due to the application that it isn't metal on metal contact such as the engine.

Engine Oil- 10w30 ( I believe)

Last time I changed my engine oil I used Mobil 1 5w30. I think I used about 5 quarts (including priming the new filter) Also be sure to get a new O-ring for your oil drain plug. If not, then get a new oil drain plug which has a new O-ring.

 

Go with Dexron 6 (not 4) for Trans, and Full Synthetic oil (even if it is Wal Mart SuperTech, it should be better than ordinary oils). Rear end, not sure, but I would follow MFR. details, while looking for a synthetic option.

You didn't ask, but I changed from DOT 3 to Valvoline DOT 4 Synthetic brake fluid -- higher wet boiling temp. (wet temp. matters more than dry when you talk of potential brake failure)...

 

Here you go...

Autozone doesn't know jack ****. If you were to read the info they say, the trans takes 5 quarts, that is not right for the manuel trans. also they do not say what type of trans fluid it is just a '?'. I have caught autozone and ol' rileysMANY times for having errorsin their info system.

Nevermind on my questions, I found a manuel for a 99 v6 camaro and it has everything I was looking for. Thanks anyway guys.

 

Boy, what a grouch!

 

That makes me want to ask. Is the full synthetic oil good for my 94 3.4L auto? I have been using a regular high milelage oil castrol since i got the car. Point is, is it safe for my engineif Iswitch to a synthetic?

 

ABSOLUTELY. I am using the Wal Mart Super Tech Full Synthetic in my '95 3.4L, and works better than any non-synthetic oil... Also use Super Tech Oil Filters (better than Fram believe it or not!)

You can switch w/no problems, it is totally safe.
