Oil brands mixing?
I'm going to buy a bottle of 5W-20 to keep in my trunk. I was wondering what brand mazda dealers use? Does it matter if I use the same brand that they put in at my service?

Here's an opinion for you from CITGO
"Myth: You can't mix brands of motor oil.
Fact: Mixing brands is not the best practice because the additive systems in each may be different and when mixed may not function as efficiently as desired. However, no serious problems will occur if you must add a different brand of equivalent quality between oil changes. It is very important to maintain proper oil level. "
I'm personally going to continue using my case of Castrol in between oil changes regardless of what brand oil the dealer uses during my oil changes. It gets too complicated logistically otherwise.
Here's another reference that says basically the same thing.

I checked with my dealer to see what they use when they change the oil (Motorcraft 5W-20 Blend). I now carry that type to top-off the oil. I am at ~1800 miles, am down 1/2 quart, and haven't added any yet.

so then my question is - because my old car mechanic asked me - are we NOT to use synthetic oil in the RX-8? Stick to the 5W-30? I'm at 2,200 and down about 1/2 quart - haven't added anything yet. Want to do it right from the get go. Thanks.
