good pm.. as i have known basta approved yung mga ginamit mo like the oil e you can still negotiate for a warranty claim.. medyo mahaba lang ang brasohan. if they void the warranty, you can ask them to provide you letter or better off ikaw ang gumawa and ask their service manager to signed.

Ofcourse they would not encourage you to service outside because mawawalan sila ng kita...

we are on same boat pare.. ako after 10K pms sa labas na lang ako.. nakakapili pa ako ng oils or i buy original parts for my ride at a reasonable price.. di gaya sa kanila normally taga talaga......
