Default Oil change issues

Well after putting the widebody fenders on..I thought changing the oil would be a cool down walk in the park. I bought the car built by a previous owner with a newly installed iron block/correct etc.

Since Iíve had the car, the hud has read 5/6 bars. Changed the oil today and have incrementally gotten to 7.5 quarts, HUD shows 4 bars on flat surface and I for the life of me can get a reading on the dipstick.

I would like to think despite what my parents say...that Iím not completely clueless but Iím pretty confused by this. I do not want to overfill.

thanks in advance

With an Iron Block, the capacity of that engine should be in the specs. . If its a built iron block with a designed oil pan, it could be anything. You should have known all of this when you got the car, or did the engine swap. Asking someone here and worse yet having someone offer a number ( oil capacity )without knowing what block is in your car is just plan stupid.
BTW the stock monoolein spring will not support an iron block for long. The C5 was designed with lean design engineering. meaning not much over kill in the design .

Got ahold of the builder. I bought the car completed so I was not involved in the build process. The HUD does have an oil level gauge.

Correct, the oil option for the HUD is oil pressure. Each segment represents ~10 psi

I'm going to guess that 7.5 is pretty well overfilled. The top hole is 'full' on the dipstick....if that hole is filled then it's full or overfilled.

Are you sure it has the right dipstick for the oil pan that's on it?

I think that what he means is,, that it has to be a custom pan for any iron block that was put in it.

many people have iron blocks in c5/6's using c5/6 pans, the blocks are essentially the same dimensions just heavier and made out of iron

The HUD shows the oil pressure, not the oil level. There will be a message on the DIC if you have a low oil level though.

the oil level is determined by the oil pan not how much oil runs though the engine !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!! (probably why you don't check the oil level with it running )

I find it interesting , how many guys can't read a dip stick
And some don't know how to open their hoods.

I am curious as to how 120lbs will wear out the leaf any faster

Whats the spring rate on a front leaf? I wanna do some math on this

if the block is a GM OE block, composition has 0 impact on oil capacity. The galleys are all the same size. As Pounder has said, the oil pan determines capacity, and there are 2 different iterations of the C5 pan, OE. Could have a 6 pan on it, or an aftermarket sheet metal pan

At the end of the day, the dipstick is your quantifier for oil capacity, not the HUD. The oil level sensor is a pass/fail: go/no go: on/off sensor, it doesn't provide linear oil level info

that being said there are lots of people running iron blocks some of them with turbos and superchargers bolted to them and I can't think of one person noting a spring failure due to this, I'm not saying it couldn't happen but if it were a common issue it most likely would have been brought up by now
