Hi guys and girls
Currently in the process of doing my valley cover gaskets as i need to flush the old contaminated oil out i was thinking of going from 15w40 to 20w50 0r 15w50, yes the commodore has seen better days and i need to make the engine last for atleast another 4 years. As it sits it has sone 336,430 klms and has been on LPG since 2008 unknown k's when it was put on LPG as i bought it with no service history. Last service i put in Shell Helix HX5 15w40 (because it was on sale at supercheap) i was thinking of switching to Castrol GTX 20W50 or Penrite HPR Diesel 15w50
Thanks in advance
