I can get kirkland full syn or chevron supreme for 12.50 for 5 quarts.
Supreme 5w 30 is syn blend,there 10w 30 is not. Not sure why 10w 30 is not a blend. Kirkland is full syn.
Engine is 2006 5.3 chevy 200k +.. change every 7k.
Just looking for overall opinions on what you would run in florida, gets hot in summer and I tow.
B.t.W. I have ran kirkland, never ran chevron. Mobil 1 H.M. in there now.
