Someone also mentioned that the GM type Supercharger oil does NOT expand with heat like other oils, which is important in a closed system.

Ohhhhh, okay. It sounds like a Group V oil. Which if that is the case, I should be able to get my hands on some.
With regards to the closed system, there is a breather nut. I would imagine it is just for the reason of expansion.
Nice find yet again. This thread rivals any other info thread I have seen. Jk, but it is really informative.
How much oil do you put in when changing sc oil?
Steven,
Since you probably will be doing this s/c oil change more than once, hit up Farnsworth and buy one of his less than $5 shipping included s/c oil suckers.
It allows you to get every drop of old oil out. I even used mine to put the new back in. And as mentioned, IF you get all of the old out it will take two 4oz bottles of GM 100% Full Synthetic Clear But Still a Little Skunky Oil to get the level to the bottom of the last thread. I wouldn't use anything but the GM stuff, however, you know me.
Scotty,
I do agree with you that you need to take into consideration the type and amount of driving that you do. But look back at your first statement: "there have been no lubricated related failures I am aware of on a 3800 and indeed I know of very few on any platform." The majority of cars nowadays are designed to last under most conditions. These cars are bought by people that goto JiffyLube, get the cheapest oil change, and do it whenever they get around to it, usually over the recommended oil change interval. And these engines hold up just fine.
Based on this, and me and my wife not driving in harsh conditions, I change our oil as I said before, every 3000 miles and with Valvoline 10W30. And I feel that this method would work great for most of the people on the board.
Again, I do agree that you need to consider how you drive, how often, temps, etc. But for our daily drivers vehicles, the above method work very well. Now if I ownded a show car that only got driven every couple weeks. Or if I had an 11 sec GTP that I took to the track on the weekends, I would consider looking into other oils. But this is not the majority of people on these boards. Most of the people on these boards, and that we talk to, drive their cars. While they may drive them hard from time to time, if they are setup properly with correct mods, they will not be subjecting the engine to any kind of conditions that warrant expensive oils with prolonged oil changes and expensive oil analysis.
Again, this is my opinion, and I always appreciate a friendly debate. And believe me, I have crunched the numbers. I know what it costs me to change my oil. And I know what it would cost me to run extended oil drain intervals with Amsoil. And I can do it cheaper with Valvoline oil from walmart and change it every 3000 miles. Call me old school, but this is what works for me. And I believe that this method will also work for the majority of other people that are going to read this and not cause premature engine failure.
where I used to work we had alldata. I remember looking up engine oil spec for my regal gs. And for every year AFTER 97 (technically 97.5) it gave full syn oil as the spec. Since then even with the high miles I have and the leaks (fixed them finally now) I put full syn in that car. Anybody seen this or have alldata to verify. Maybe I interpreted the data wrong.
