Anyone know the top speed for the CXS? been searching all over and can only find the 0 to 60 and 1/4th mile times..





Also any owners wanna let me know what type of oil and filter you like
to use on your car? I just picked up a PureOne filter and Mobil
Clean 7500 for my first change..

well, one thing that i can tell you, i would never trust that "change your oil every 7500" crap...i run synthetic in my car.

Is it true that most Buicks are limited at 108? I read a post somewhere about that..



I'm probably going to run Mobil 1 full synthetic next time, just wanted
to use a blend this time because I'm going to do another shorter
interval to help flush out the break in metals.



I wonder if the drain plug on this engine is the same as the 3800
V6? I'm going to order a magnetic drain plug, but the site I
wanted to get it from said Buick hasn't released any info on the size
but that all Buicks for the last 10 years have had the same size plug.

the dealership part dept would be able to tell you if the plug number crosses over to the 3800...as for the speed limiter, that ususally varies model to model...
