Ive been using Mobil 1 10W 30 and was wondering if I should start using 15W50. Ive been told that 15W 50 from Mobil 1 is a performance driving oil.

I ran some Mobil 1 15w50 last summer in my 99 gt w/110k on it, actually
it ran good , left it in for 4k miles, had no problems at all. This is Texas so
it is hot here in the summer. It made the engine have a smoother feel but
a bit slower reving feel also. Now I am running 5w30 Motorcraft Blend in my 04.

Yes RP is the way to go its costs a bit more but its worth it. If you dont use it be sure to throw a can of RESTORE in the car every oil change, trust me once it works itself in you can feel the difference, i felt it about 350-400 miles after i dumped it in there. It says it needs 500 to work itself in
