I have an 2004 M6s. I use full synthetic motor oil and it usually costs me around $30-$35 bucks to change it.
That is with 6 quarts of Pennzoil Platinum 5w-20 and a TG2 Fram oil filter.

I am just wondering if this is a good, bad, or average cost across the nation/world?

 

I use Castrol mineral oil, and a Purolator PureOne filter. Cost is about $20.00, and I enjoythe work ('cause wifey and the kids won't come near me!). Cheers,

David

 

I can stand Pennzoil...it tends to leave a waxy residue in the engine. Not a problem so long as you NEVER switch to synthetic. If you switch, it will wash all of that residue into your filter, clog it up, and starve your engine of oil. My friend has a 73 240Z widebody with a Ford 302 in it that this happened to.

Valvoline oil, Fram filter - $28

 

Quaker State Synthetic 5W20, with a QS oil filter.
$60 cdn, at the canadian tire i work at.....

 

Sstlaure, I have run full synthetic in mine since the day I bought itand never had a problem. Are you saying I should switch back to conventional oil?

 

DO NOT SWITCH BACK TO CONVENTIONAL!

 

I use syntetic 5w-20 mobil 1 oil and k&n filter can cost me 40 bucks for 6 quarts.

 

Synthetic isn't a problem...When you run into a problem is when you run a paraffin based oil (like Pennzoil, I believe Quaker State is that way as well) for a period of time. This allows some of this essentially wax to build up on the internals of your engine (I think they advertise it as the "Pentastar molecule"....If you switch over to synthetic, it reacts with this build-up and flushes it out of the engine clogging the filter.

If you've always ran synthetic, there is no problem.
