Just wondering what kind of oil to use?
just like the title states...

 

It wouldn't matter what oil you use as long as you follow mazda's recommended weights. Castrol GTX is a good one to go with. Run 20w-50 whenever weather allows it...

 

I really love Castrol GTX.. I've used it in EVERY vehicle I've owned.

 

ok what do u mean by weather?

ok lets rephrase that, When its hot, what do you use?
and when its cold, what do you use?

 

When its hot, 20w-50, when its cold (below 32F or near it) 10w-30.

 

oh ok.. Thank you. I really appreciate the awesome info.. seriously

 

I made a mistake, I was thinking 32C (confused my units). Use 10w30 when its 0F, 32C or near it or below it. Otherwise 20w-50.

I use Mobil 1 15w50, love it.

 

I wonder if the people who "love" an oil and have "always used" an oil have any basis of comparison for saying their choice is better then another?

Just a thought.

Oh, and I run 20-50 (my car is really only driven in the summer) of whatever brand is on sale when I need oil. Generally I use Fram filters because Canadian Tire seems to only carry a filter for the RX-7 from Fram.
