I used the Mobil 1 truck/suv, but I really doubt there is much difference. If I go to buy oil next time and they only have the regular Mobil 1, or there is a price difference, I wouldn't hesitate to use the 'normal'.
I used the Nissan filters, bought 10 of them and 10 of the oil drain plug crush gaskets online.
The factory filter was hell to get off, that was on TIGHT. I had to dent it up pretty good to get it off.
I don't know how much of it is break in and how much is the oil change, but I have been getting better and better mileage.
I've driven just over 1K miles since changing over to Mobil 1.
I've gone from 15.2-15.7 in town to 15.9-16.3, and about 21 pure highway to 22. The biggest difference is in towing though. I tow a boat a lot and was getting 11.4-11.6 mpg. Last weekend I towed about 250miles and got 13.6mpg.
I used to have a VR6 Jetta, they have aluminum oil pans and mine hit a chunk of ice on the highway in the winter and knocked a golf ball sized hole in it, but I didn't think I had done damage. The oil pressure light failed and I drove about 5-7 miles. Parked and let the car sit. On start up the light did come on and I shut it off. On inspection there was very little oil on the ground so that means that before parking I drove w/o oil for awhile (at 70+mph).
I had Mobil 1 in the car. No engine damage, just replaced the pan, refilled the oil, and drove it for 85K more miles (including 3 seasons of autoX racing). Car ran like new when I sold it.
