Castrol GTX Full Synthetic 5W-30 Motor Oil, 5 Quarts - Amazon - 21.45 or 20.38 S/S

Think this oil is any better than kirkland full synthetic? That deal is coming up and I think jugs will be $15-16 in the 2 packs
 
It’s good oil, most full synthetic oil is about the same, hang on the oil police will be here to correct my statement 😂
I always considered the Warren oil (kirkland, supertech, mag1, etc) equivalent to more entry level full synthetics like mobil fs, PZ fs, castrol fs, etc. And the flagship varieties like m1 vanilla, castrol edge, PP, and valvoline advanced fs a step above the entry level. And finally more premium options even better like m1 extended, pup, edge extended, valvoline extended, etc.

Warren is NO joke!!! One of my racing shop customers did a "projectfarm" type of test and he said Supertech was TOP winner of his heat test!!!:cool:(y)
