and PLEASE focus on the question itself. And no other questions about..."why would anyone want to do this"? or "what are you NUTS"? etc.
If an engine & owner's manual require ONLY 0W20 motor oil and no other optional oil grades listed in the OM, will using a 5W20 or 5W30 conventional(which are actually a synblend), hurt the engine for the occasional OCI?
OK, maybe don't run this OCI on dino 5W20 or 5W30 for the full length synthetic OCI(6k-8k miles) but maybe for 3k-4k miles?
This has been a question that has haunted me since there are so many newer vehicles/engines that require the 0W20 and NOTHING ELSE.
Thanks,
