    So much info on Hellcats, right down to videos of oil changes... not so much for us SRT 392 owners.

    First oil change coming up. I've seen all sorts of discussion of draining the oil cooler (separately) on the Hellcats, but see no evidence of a separate oil cooler when peaking thru the lower grille of the SRT 392. What's a little surprising, if there is none, is that the SRT 392 spec's a quart MORE oil than the Hellcat... not less.

    Can anyone state with authority whether or not the SRT 392 has an oil cooler which should be drained during oil change?

    The 392 does not have the oil cooler that needs to be drained..just the HC...I own both...

    Thanks! Any guess as to why the 392 takes a quart more oil?

    Not really sure why one less qt. You would think with the cooler and lines it would require more. I assume the crankcase pan is maybe smaller though the reduction may be due to the beefier block of the 6.2...

    From 5.7l/6.1l configs to the 6.1l/6.4/ all hemis have used 7 quart pans. Extra volume of oil helps keep the motor safe in a bunch of ways.

    Hellcat decided on oil cooler to offset lower oil volume in the pan.

    Also due to higher heat loads from forced induction.

    "Beefier block"? I thought they were the same block, albeit populated with different heads and supercharger. Dodge marketing states Hellcat also has forged crank and pistons, but they're unclear on the crank and pistons in the SRT 392.

    I've not seen any literature that states they're different blocks, but I'll admit I haven't read it all. In any case, oil capacity is dictated by pan, not block.

    Last scribblings I recall had engine at 90% rework to be able to withstand addition of supercharger . Lots of updates...even displacement changed to a 6.2l

    The blocks are different. The beefier block could dictate the size of the pan...just a shot in the dark since I don't know why 6qts instead of 7...

    The 392 has a forged crank but not the pistons and rods....
