k, i just finished my car finally, and i'm replacing my oil, but i lost by big blue book!!! quick how much oil does a 1981 12a need, and what is the stock oil recomendation!!! please help!!!

 

usually almost 5 quarts

I run 20w/50

 

Yep, for a stock car still using the OMP get some castrol GTX 20w50. 5 quarts should do it.

 

Guy's, he's in Canada. I would run a thinner oil. 10/30 or 5/30. In the summer 20/50 would be ok. Amsoil has a very sweet 0-30 oil, buy dino works great and costs less.

 

what about a 13B? sorry for the thread jack

 

For 12a anyway(dont know about 13b)

-10 to 50*C......................20w50
-10 to 40*C......................20w40
-18 to 50*C......................10w50
-18 to 40*C......................10w40
-18 to 30*C......................10w30
Below -18*C.....................5w20 or 5w30

 

probably the same for 13b. I would think??

 

We are in summer

 

The 20w50 is fine in the winter too. It makes it a bit harder to start, but not much.

 

thanks everyone, car was sweet, i'll have pics up soon almost got pulled over......

 

Speeding?

 

lol..... yeah, hey, first time out legally on the highway...... dosn't help that my car looks fast

 

LoL, I'm really suprised I've never gotten a ticket in my 7. I've gotten one in a mercury sable, and in a chevy astro van, but not in the 7
