How do you rate those three types of engine oil from good to best? Thank you for your inputs.
Mas maige kung Delo 400 ka na lang kung ganyan din lang presyo ng Petron. P295/li ang bili ko sa Delo 400 (not the two Delo Golds ha).

Delo 400 is API CI-4 plus/CI4/CH4/CG4/CF4/CF/SL afaik sa label nya plus other oil tests like MB, JASO, pati Cummins pa ata.

TBN as per one pds is 12.6 tapos 10.5 naman yung nakita ko sa ibang pds pero i think that's the LE version which is CJ-4 na. or maybe yung 2 ASTM test yun with regards to TBN (D2896 and D4379). either way, considered pa rin na mataas yung TBN nya.
