It's now time for an oil change on my '95 Civic. The owner's manual I
downloaded recommends 5W-30, but here in the Philippines all I can
find is 10W-40 and 10W-50. People look at me strange when I ask for
We're located very near the equator, very hot tropical climate and it
never snows; is it safe to use the thicker viscosities? Will it affect
BTW: Does it even make sense to buy multigrade oils here?
Multigrade, yes. 5W-30, no. The manual you downloaded was almost certainly
intended for US use and US climate.
Use either 10W-40 or 10W-50 and don't worry about it. 5W is too thin for
You certainly don't need 5W-30, but those wide viscosity range oils
have a bad reputation for breaking down. 10W-30 would be acceptable.
What is the lowest temperature you ever see? I am guessing that your
teeth start chattering at 18C ;-) If that is the bottom you could
even try 20W-40 as long as you don't hear any noise at start-up.
I doubt if you notice any drop in mileage. I guarantee you will get
better mileage than running 5W-30 in Chicago next weekend when the

Today it's a 'freezing' 26C (79F), people are already saying it's too
Thanks for all the advice. After reading your replies, I went out and
