Use Mobil 1. Nearly everyone I know uses it in my area and it works great. Also don't have to do an oil change as much. With synthetic oil around 10,000 miles. I saw a commercial for a high performance version of Mobil 1 on Car and Driver not that long ago.

My dealer does my changes every 4000 miles (free, if we pay for other periodic service). He uses the Mazda rotary oil. Can't go wrong with that deal.

~60% with Castrol GTX -- Predictable results. Mazda NA uses Castrol... the majority of owners will do what the Mfg'er suggests (I am one of them) given how MNAO has responded to Warranty issues. I want to use Synthetic, understand the arguments that have been made ad nauseam on this forum, and have chosen so far to stay with the Dino oil used by MNAO.

Well, my baby is still brand new (1800 miles) and since I broke in the engine just a tad harder than recommended by some on this board (hit 6K once or twice at about 500 miles), I decided to do the first oil change at 1500 miles. I had the dealer do it, since I had a coupon to get it done for free. They used "Mazda Oil" 5W-20 so I bought two quarts extra which they only charged me at US$ 3.43 per quart. I keep one in the car for topping off. It just seemed like as long as I am having the dealer change my oil, I might as well use the same stuff as they do.

Is this true? Castrol helped develop the oil for Mazda?

I don't know why you put Havoline up there. Not too many people know about it.

It's an Eastern oil brand anyhow.

It's hard to find it out here in Calf. So to stay consistant along with all my other vehicles Castrol. Been using Castrol for over 25 yrs. now.

So here it is. This is NOT a post asking people for advice on what oil to use because that has been covered. This is more of a study to see what percentages of people are using a particular brand. Nothing more, nothing less.

castrol or RP.. change it up now and again.

I've been using Castrol well before I even heard of Mazda. It's good stuff. Didn't know that Mazda recommends it. Mazda must be John Force fans...but who wouldn't be a John Force fan?

Castrol GTX for superior sludge protection. It's more than just oil its liquid engineering.

I would say to use Mobil 1 ... as Royal Purple costs a lot more and you'll probably find no difference between them.
