I've been skulking about this board for a while and have learned more in a week or two about oils, filters, and the like than in the previous 50+ years. I'm still a tad confused as to which synthetic multi-vis (weight not brand) would be ideal for my car & conditions.
The car:'03 Corolla 1.8l four banger 5 spd manual
Recommended oil: 5W-30 year round 4QT capacity W/filter
Area: central/south TX - rarely freezes, 100+F common, A/C almost always on.
Driving habits: as most, some city, some highway. Very few short drives. Revved above 5000 RPM often.
I've read enough to make an informed synthetic oil & filter brand choice but which of these would you use?
0W-30 0W-40 5W-30 10W-30
Thank you from a 1st time poster
