Fuel Pump/Oil/Octance

[OldYellerSpeed]

i heard its not good to fill your gas tank up from emptry constantly. Aslo what kinda oil does everyone use. I use Mobil1 5/30 Synthetic. How many km do you usally drive before an oil change?. What octance do you use?

Its not good to let the tank go empty all the time is true. You should keep at least an 1/8th of a tank at all times.

5w/40 synthetic.

Every 3months, I never get to 3k miles.

At least 93.

Correct, constantly refueling on empty means your fuel pump may be picking up sediment that settles at the bottom of the tank.
I use Mobil 1 10w-30, and 93 octane.

Well that, and modern day fuel pumps are both cooled and lubricated with the surrounding fuel.
