Thanks I will have it removed

It seems like the new SA is NOT happy about me removing some items kasi 2021 pa daw since my last change oil [emoji35] I said I follow every 5k and that takes me a long time talaga.

I have to remember to buy coolant, I will do it myself. Then I will ask for old parts and the excess oil
