2007 Elantra, 2.0 I4, 150,000 miles. Manual states 5W-20 or 5W-30 for all temps and that 10W-30 can be used above 0F.
Has anyone had any problem with using 10W-30? I'm switching to synthetic and am going to use Valvoline Maxlife Full Syn as well as 10W-30 to minimize the possibility of leaks.
Would you use 5W-30 or 10W-30?
Also the 10W-30 has 7.8% Noack loss, and the 5W has 9.3%
