Where I live , they cost exactly the same. I know that Delo 400 is a CI4+ spec and the Gold is a CH4 spec , but why do they cost the same ?
Do they use different base oils ? Are they both group 2 ? I noticed the ISOSYN logo on both.
How good are group 2 ISOSYN base stocks compared to group 3 and 4 oils ? Do the additives make up for the cheaper base stocks in Delo compared to group 3 HDEO like Shel and Mobil ?
