I just purchased a pampered 03 ssei driven buy a 60+ lady that I know well. My owners manual didn't say when to change the oil, just when to check it. Maybe I was looking with my eyes closed. Do I have to use the GM stuff or can I use something else..., synthetic maybe???
It'* hard to believe that you never have to change it.

Your about due I would say, really depends on the miles. Yes, you MUST use the correct GM stuff, do NOT put anything else in there.

Here'* the stuff you need. INTENSE-Racing.com: INTENSE Supercharger Oil (8oz)

Even the dealership FSM'* say only to check at each 30K interval. Personally I change it about once a year. Which happens to be about 30K miles for me.

I have 70ooo miles on it. The previos owner brought it in to the dealer for everything. I have all their recepts, I'm gonna go through them and see if it was ever done.
Thanks

I'll put a buck on it never being done. In all the FSM'* I've read and looked through..it only says check and fill if needed. =0)

I'll put a buck on it never being done.

Billboost You owe me a buck. I looked back through all the receipts and the oil was changed at about 55k and also the LIM gasket and some other stuff.

The mitchel program at my school said to use 5w30 synthetic.

reminder to myself... guys help out lol

I have a tech bulletin stating to use the gm oil if applicable... see Danthurs link above to order, or consult local gm dealer IF they have it... if NOT available the bulletin states that MOBIL1 5w30 synthetic is a comparable replacement for dealers to use, now if dealers can use it, i dont see why we cant... its not the same by any means and they want it to be changed out every 15,000 miles vs 30,000 for the gm SC oil but its still an option for those that want
