My mechanic likes to use Castrol extended and change oil every 5000 miles. I have alway s used Pennzoil 10/30 and changed oil every 3000 miles. which one is right? Or both of us right? Whaddaya think guys?


The great oil debate continues. The debate nowadays is how long between
changes.

If your vehicle requires 10w-30, then that's what you need to use. Brand
is a matter of preference, though, I prefer Pennzoil also. What matters
most is the grade.

Today's engines are well designed to drive farther than the 3000 mile
change, especially if using synthetic blends. Though, you didn't provide
vehicle info, I'll guess it as within 10 years old and the 5000 mile
change will not hurt it, thus, the 3000 surely won't hurt either. You're
just spending more money. It is recommended to follow the manufacturers
guide in the manual.
