Hi everyone! This thread proved to be some heavy reading, but it helped me understand more about oil and oil filters. Kudos!
Some questions that I have:
1. Is the BT223/ B233 also applicable for older units of Toyota Corona? Mine is a 3SF engine model.
2. Also tried looking for cross reference for a B1446 for Isuzu Xwind (4jai1), it seems that the B109 will also fit. Can anyone confirm this?

Also for the Xwind, is it advisable to use the Mobile delvac mx 15w 40? Saw one at true value priced at P1184 for the one gallon
Thanks a lot!
