Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
To a small extent. Really it's just because the systems on modern engines hold more oil. More oil, more cleaning agents, more kms.
Sorry Pollushon I don't agree with that.
How much oil does the newest V6 engine in the VF commodore hold?
I know what you mean mate ^^^
Guess my next question would be can I just add these into the existing oils? There is no cross contamination or anything to worry about right?
