Oil for Mazda 3 2.3L

[Jyn]

I'm currently using Pennzoil Platinum 5w-20. My commute currently is through town (no highway), 45mph with a few stoplights. However, my commute may be changing to 90+ mile round-trip driving (keyword: maybe).

Climate: Texas -- consistent 30's-50's right now. Summers will be triple digits.

Stick with the same weight? Same oil? Completely new to Japanese cars.

Pennzoil Platinum is a very good oil that will work well in your Mazda3.

Most people here will just advise you stick with the recommended weight. if Mazda backs a 5w20, nothing wrong with using Pennzoil Platinum 5w20, even in such temps.

Castrol edge 5w30 is pretty much a 20w oil and is very good and often on sale at Advanced Auto. Mobil 1 Extended Performance 5w20 is a fine oil too, could always go with the Mobil 1 0w20 for maximum fuel economy.

I have the same engine and also use Pennzoil Platinum 5w20 - runs great.

In the summer you could go with a thinner 5w30 since this car has zero oil cooling. I use 0w-20 now but will be a 0w30 user next week because I tend to drive pretty hard on twisty roads for extended periods.

You will be in good shape with your current selection.
