Does anyone have information on the drain interval for these oils?
Any weight of their oils.
I can not find that information anywhere.
In my non scientific opinion, I am thinking 7500 to 10,000 miles.

Thank you.

It depends more on the engine than on the oil.

Their Gold Jug Castrol Extended Protection is rated for 15,000 mile OCI's.

Its right on the Jug what ever that's worth.

UOA will be your best bet but a quality syn like Castrol should have no problem doing 7500 miles.

On 5w20 Edge EP I've had UOA's at just over 11k with good results. Currently closing in on 10k for the current fill of it.
