Is bigger than yours.


In class they tell the techs that the correct weight synthetic is required - the FB motors have no oil coolers and are designed to run hotter to keep the oil as thin as possible, because the cam timing is adjusted by using valve spring tension to shuttle oil back and forth between chambers in the cam sprocket.

Thick sludged up oil doesn't move very fast, and if you start having cam timing issues the oil is the first place to look...

Having said that, a good conventional oil probably won't do you wrong.
