Oh, NO! Not the bi Monthly do I dump the factory fill early -
again !
Still unresolved, and it will likely remain so. Has anyone seen a study on a group of engines with teardowns?
If not We will never know with DATA in hand - and that may not apply in your circumstance.
Except on Non-filtered non- pressure lubed ODPE it's NEVER done anything good - only bad - for me,
and I've broken in
over 70 new car engines over a 1/2 century into the past millennium.
A good sample size.
Early change will not get out large pieces of gasket and silicone material blocking the filter pickup
That requires a pan drop. everything else damaging will stay in the pan bottom or be captured by the
Oil filter
Break in is important - on what you avoid. I try to avoid long trips in the first run in and the first 750 miles.
Every engine that got long tripped early ran poorly. Also avoid high rpms - but don't lug either. I like to short heat cycle the engine - don't run it for more than say 20mins without a shut down and cool down. This seems to work.
I would leave the FF in for at LEAST 2500-3500 miles. My 2019 Jetta lease had exceptionally good factory oil and an excellent factory filter. That stayed in and was performing superbly for 6Kmi 10 month when i had them change it. What they put in
wasn't good. In fact it was the wrong spec and the wrong grade (5W40 vs. required 0W20)
