Blackwing Maintenance Regimen

So odd, I heard some cars seem to like 10. My car has been reliably a 9qt machine.

My ZL1 called for 10qts as well. I assume the oil pans may be different between on the LT4s between the ZL1 and 5BW.

No difference in oil pans visually speaking

I am curious what the actual difference is? Both wet sump, same oil filter, I figured the oil pan was slightly different but not sure what else would change the recommended capacity.

It is documented that the LT4 in the 5BW takes 9qts vs 10qts in the C7 Z06 and ZL1. I thought it was a misprint at first.

I believe the dipsticks are different. The end to the cross hatch is a few millimeters lower while the ZL1 dipsticks I've seen have the cross hatch pattern continue to the end of the bulb. Perhaps GM just adjusted their specs on what is sufficient for lubrication on these motors in the face of rising consumption and environmental concerns?

Is this okay? I ordered Dexos 1 gen 2 but received Dexos 1 gen 3. I assume it’s okay but want to check. 4BW.

Wouldn't be the 1st time GM has changed the length of dipstick and adjusted the oil fill capacities? Mine is slightly above top hash with new filter and 9qts.

Mopar does the same crap with the hellcats. Even the manual and dealers info in computer is different. Had some say 6qts and others 7. Can’t believe this with such an expensive car.

I install 8, then do the final adjustment after that has been run around the block and then sat overnight. I like the cold level to be a couple mm below the full mark and 8.5 gets me there.

For the 10qt crowd, what is your oil level cold and on level ground?

I've never seen a higher generation of a fluid come out that was not backward compatible when superceding the previous generations (ex. the multiple iterations of Dexron trans fluid).

This makes me feel better. Dealership did 8.8 on my first oil change.

Yup, that should put it right at the top line above hash

Dexos2 or DexosR is what the LT4 asks for

Thanks. Mine is the LF4 though, I have a CT4 V BW.

Can you take a picture of what you have? This is what the 4BW calls for. I buy it at Walmart to save some money, they also sell the AC Delco PF63 filter there as well.

I've never seen a higher generation of a fluid come out that was not backward compatible when superceding the previous generations (ex. the multiple iterations of Dexron trans fluid).

The only time I know of that happening is with the manual transmission fluid in the gen 2 CTS-V. It used Dexos 3 ATF and when the newer one came out it specifically stated to not use it, and AC Delco sold a "Manual Transmission Fluid" that was really dexos 3 ATF. But that was a special case of use ATF in a manual transmission.

Yes, that is the right stuff.

Mobil 1 Dexos gen 2 0w40 now goes by the Mobil 1 Supercar label

I changed my 5BW oil at 500 miles about 10 months ago maybe. I’m at 4k miles with 3 track days, and it says I’m at 7%. Does that seem right after only putting 3500 miles on this oil?

Time is also factored into the algorithm for oil changes. Oil life will decrease with time. At lease a yearly change is part of the regimen.

Be careful ordering filters from Amazon. I got a knock off.
