Engine Oil: what's best?

I've never had this problem with either the Mobil1 or Shell Helix Ultra fully synthetics.

I agree, I have been using Castrol Edge Titanium 5w40, and more recently Shell Helix Ultra 5w40 and am pleasantly surprised with the results thus far.

Ammerty, I've never been a fan of Castrol, they've always seemed to be inferior performers of the big name brands. Personally, I'd just stick with the Helix Ultra as it was always a good oil in both my TJ exec & KJ AWD.

I agree with you in terms of Magnatec products (I never used it on the Magna, my Elantra hated it), but the Edge stuff seems to be pretty good. Coincidentally, I bought more Helix Ultra today on sale for $52.

I use Penrite in all of my cars as it seems the Mechanics I have spoken to recommend it, HPR5 is expensive but worth it.
