I changed my SC oil today. The part # given was 10953513 the part # I got was 12345982 which is a 4 oz. bottle, I got 2 of them. Everything went smoothly but the oil did not fill it to the bottom of the threads. When I took the old oil out I got only 3 1/4 oz. The final fill I put in 3 5/8 oz. Is this right or should the bottles been 8oz. Thanks

You should fill it to the bottom the threads if you used two bottles. If its not to the bottom of the threads, put more in.

It took a little over 6 oz. to fill it up. The next time I flush and fill I'll get 16 oz. [4-4oz] this might save somebody from making 2 trips to GM
