Mine will, malibudragon.Maybe they will let me pay the difference hmmm..
15W-50 is a good pick...what weight are you using...?
i'm ready for my first change, and i'll switch over to sythetic, as I usually do...
just wanted some input on the change, if you noticed any difference...
Valvoline's Synpower is a strange offering. Claims better wear numbers than Mobil 1 (in an obsolete 4-ball wear test) but oddly won't pass GM 4718M specs for synthetic oil requirements. It failed the high-temp deposit test, which is ironic considering that is one of the major advantages of a synthetic offering.I am going to switch over to Mobil 1 5W30 in about 1000 miles. I have been very happy with their product. I have been interesed in Valvoline's new Synthetic line however, I will probably stay with Mobil 1. There was a post elsewhere in this forum where the author stated that if they brought the product (oil and filter) to the dealership, they would only charge him for the labor. I dont mind changing the oil myself, but it is kind of a pain in the winter, especially when you have to go get your tires rotated anyways. I have not asked my dealership if they would do that for me... I am sceptical if they would really use the synthetic or just pocket it (for Corvette changes) and use the cheap GM oil on my car.![]()
One thing Ive noticed when changing my synthetic oil is how much cleaner it is. If you have has used dino oil on your hands it takes forever to get off the smell. Mobil 1 cleans up easily with no extended smell.Valvoline's Synpower is a strange offering.

I don't trust the dealership to do hardly ANYTHING right. If you walked in with a jug of oil and asked them to use it, you would leave with their bulk oil in your sump and your new jug of synthetic in the service guy's oil stash. Also, they don't stock quarts of synthetic oil. They have drums of synthetic just like the dino, because so many of GMs new vehicles are now requiring synthetic.
Don't waste your money on synthetic if you aren't going to streach your oil change intervals. The cheapest SM rated dino will give you IDENTICAL wear numbers to synthetic oils at 5K intervals. No joke. If you're going to actually streach your OCIs longer, then synthetic is a more worthy candidate. Too many people have false notions of what synthetic oil can/can't do. One of the things synthetic is best at is eating unnecessary holes in peoples wallets.
We actually use synthetic up here Impacted not for the longer intervals, but the viscosity doesn't change like dino oil in the cold temperatures. It stays really fluid in the cold, and can still travel through the oil galleries alot easier and sooner. Which in turn lubricates the engine sooner at -30 C.Don't waste your money on synthetic if you aren't going to streach your oil change intervals.

I would have dumped the oil and filter 1100 miles agoI'm thinking about doing the same too, with my 2009 3.6L.
At 2100 miles now and still 76%, so also not sure when to get the first change done. My father keeps my mother's '08 2.4L on his lifetime 3k mile dino oil & filter changes like clockwork, but synthetic & 5k seems like a good move...once I figure out when to get the first one done.
