I just started using supertech and Kirkland brand syn oils
5w 30 Kirkland, 5w 30 Hm supertech and 10w 30 supertech
I have noticed all 3 smell the same, different/stronger oil smell than castrol/penzoil/mobil 1/Q.S. synthetics.
Not that I sniff oil but when you pour it the smell does hit you, so I smelled them all to compare.
Any ideas why ?
Add packs ? not refined as much ? Less syn oil ?
I don't have any non-syn oil to compare it too.
