im changing the oil today for the first time in this cars life with me. 45k miles.

im using mobile 1 fully synthetic oil with a wix oil filter.

how long should i go between oil changes with fully synthetic? should i be using fully synthetic or not? is mobile 1 good, or should i be using valvoline, or some other brand?

these questions have occured to me while procuring the oil. any input would be appreciated and a quick use of the search function revealed no real knowledge on the subject to me.

Mobil1 has been tested beyond 10k miles as good.

I personally go 5k on the Zilla. SLE get'* dino-juice.

thanks will.

one more question (and a stupid one at that): how many quarts does it hold?

About 4 1/2.

thank you will and jr. now i remember why i decided to do this myself instead of paying someone else to do it.

hm. somehow it hadnt occurred to me to look on the dipstick.

I cant tell you how nice it is having access to two hoists at work, and a 6 bay 14 truck shop...hehe makes oil changes a breeze even in -40.
5000 miles is defintally a good interval, but dont feel too too bad if you go over that by a bit..I pushed 6500 on my last oil change..had a trip to oregon in there too..

For the past 8 months I have changed my Mobil 1 every 3000 miles as I would any other oil. But after reading an interesting article on Mobil 1, and what others have done, I think I will change it every 5,000 now. One point in the article was that as oil ages, engine wear decreases. So "compulsive" oil changers could benefit from changing oil less often.

is this article online? id be interested to read it.

I usually change my Mobil 1 every 5000 or so. It does the job.
