Mobil Synthetic 10w30 or other weight
Switched about 1000 miles ago to Mobil 1 Super Syn 10w30. Car does feel smoother but idle is rougher alittle now......i heard this is due to the oil acting like a detergent for sludge build up and I'm freeing it now.
So I heard from a member to next time use 15w50.....any ideas?

I like the 15W50 also. I formerly used 20W50, non-synthetic, but switched to Mobil 1. I haven't noticed much difference in the viscosity grade change but it seems to idle better with the synthetic than it did with the regular oil.
