"Mobile" is in Alabama. "Mobil" is oil.

I use mobil 1, and so did the previous owner of my car. I'm probably not going to change it for another 3k mi, I don't know when it was changed last but it was less than 10k mi ago, and the car was switched over to synthetic at around 20k mi. It now has 70k mi on it and runnning strong!
I think that mobil 1 wil last for 20k miles tho.

Does anyone recommend a certain weight oil for 6,800rpm? My new cam will be up that much soon. (after I rebuild my 6speed)
I use Mobil 5w30 now, but I'm worried about oil film thickness at close to 7k rpm
Any advise?

You shouldn't be worried. Do your regular oil changes and you shouldn't have a problem.
Btw, I've torn apart motors who's owners religiously change their oil. They actually look new inside.
Oh, I change my oil every 3k miles with no problems.

Even dino oil will last longer then 3,000 miles. Car guys are just overly **** and change early. I just changed mine after 2k miles.
Mobile 1 is probably good to over 5k though.

I'm changing it at 10k intervals now. That motor hasn't burned a drop of oil in 40k miles.
BTW, I change out the oil in my fbod about 5-7k miles and I am using GC 0w30. I'm going to try the Mobil 0w40 next change.

If you unsure about your oil you should check out http://www.blackstone-labs.com/.
They'll tell you if you're hurting anything and if you are overextending your oil changes.

I have used Mobil 1 15-50w since 1984 when I started using it in my 1984 15th Ann. TA. I have used it in all my vehicles since and currently use it in my 30th Ann. TA and F-150 - both with a Mobil 1 oil filter and Prolong oil additive. I have always changed it at 6,500 miles and have never had any oil related issues.

when you swith to synthetic oil check your oil levels to see if you are burning oil. most synthetics will use more oil than non-synthetic oil. so if you were burning oil before and didn't notice it, you may notice it when you change but don't worry a little burning of oil is common just make sure you have the proper levels, and its not burning a lot of oil. I also use mobil 1, and no problems.
