i have a 2006 pontiac grand prix gt supercharged 3.8 and i was wondering what kind of oil should i use ??

**noreasonwhyy** · 06-09-2010

royal purple 5w30

I use Mobil 1 5w-30 every 3k with the bigger filter. Thinking about using castrol edge on the next change to see if it runs cleaner through the changes.

changed your title because i hated your caps and how long it was.

also, did you search a little? there are at least 10 threads about this subject.

Synthetic!

synthetic

always used valvoline but I have used Mobil 1 10w-30 every since getting into grand prixs. Many 3800 owners use it

if you want to use synthetic use it if you wanna use conventional use it
main thing is dont go over oil change intervals and use quality filters

i personaly use synthetic what ever is in sale at the time i buy and its as cheap as conventional

I just got my GP and changed the oil to Mobil 1 5w/30 with an m1-101 filter and I can't believe how much easier it 'rolls' down the road. I would definitely run synthetics.

"I just got my GP and changed the oil to Mobil 1 5w/30 with an m1-101 filter and I can't believe how much easier it 'rolls' down the road. I would definitely run synthetics."

Am I the only one that has never noticed oil make a difference in performance whether it had synthetic or GoJo (with the grit) in it?

I run Mobil 1 oil and Pureone or mobil 1 / K&N filters. I run synthetic because it doesn't darken near as fast from heat and holds up better overall. Not because i've ever felt an effect in performance. There are plenty of writeups on synthetic vs conventional oil on the net.

However as Bio248 stated there are plenty of threads on this subject and these threads always start arguments.

put oil in your car. it will run.

do not put oil in your car. it will not run.

I use conventional oil, as the service records from the previous owner also indicate oil change intervals of 4-7k miles from day one with standard oil. It now has 150,000 and is very clean inside and runs perfect, only uses about 8oz ever 3000 miles.
I change the oil around 3-4k miles, and use A/C or STP filter. (pf47)
If it aint broke, I aint gunna fix it with synthetic.
