Default Oil change questions

Few questions for a c5 z06 owners first oil change. I have done oil changes on my previous cars.
1. Does the rear have to be angled higher than the front? I was planning to use my quickjack to do the oil change.
2. Should I replace the oil drain plug with a magnetic drain plug? Or just change the rubber gaske What do you recommend?
3. What are your thoughts on fumoto/quick oil drain valve? I've used them in the past on most cars without issue but the Z is low.
Thanks in advance.

1- Level is fine
2- Magnetic ones are fine and as for the gasket on the stock one it is built in, your replace the drain bolt
3- I don't use one- Maybe someone else will chime in on that idea

When draining oil, the baffles in the C5 batwing oil pan trap more oil if the pan is not level.

Probably not crucial. Those of us with engine oil coolers always have some trapped oil in the oil coolers and oil lines when oil is drained.

Thanks for the info. I'm going to get a magnetic drain plug from midwest corvette and change it for the next oil change.

Can you even get a Fumoto installed between the pan and the cradle?

You cant even get a socket in there...

Not a big fan of the Fumoto valve drain plug.

Why you ask - Well two reasons..

1) If the drain plug is at the bottom of the pan, that valve has to hang down a bit lower - making it the lowest thing - so it's possible it will be hit and broken off by some road debris - probably not likely - but more likely than the plug getting broken off...

2) The idea of the oil drain is to get as much old oil out as possible - I tend to think that anything that screws into the drain plug hole will have some amount of "height" and will leave a little oil in the pan. I completely "get" that we do not get ALL the oil oil out when we do a drain - but I'm looking to find ways to get more of the old oil out - not leave more of the old oil in.

To me - Unscrewing the drain plug is easy. So - I see no real advantage for the valve - but if you think it's an improvement - go for it...

with that oil drain valve you’re asking for trouble.

Default oll drain valve - too low!

I installed an oil drain valve on my 2000 C5 and was immediately concerned about it being too low. It only hung down about an inch so I tried it out. Sure enough, on my next oil change I saw that it had taken a hit from some object. Off it came and back on with the stock plug. A nice sat of geared ratchets, like Craftsman or something similar, make reaching and removing that plug fairly easy.

Thanks for the heads up. I need to get some geared ratchets. More tools more fun 🙂
