Just wondering.......I am about to check my oil for the first time....

I use 5 -20 non syntheic

 

A lot of other Forum members have said Castrol is the best brand. I used to be a Valvoline person but, have switched to Castrol. The boat is still out on Synthetics, some say no, some say yes. But that would be with a complete change.

 

Have to agree with the Castrol. Talked to a Mazda mechanic here in Baltimore and he stated that they use Castrol 5-20 in the service shop. He did say you can buy a Mazda-branded 5-20 from the parts catalog, but it costs about a buck more than the Castrol per quart.

Enjoy your drive...

5w-20 castrol.

 

I'll be running Mobil1 5w30. Got some on hand so that's what I'm using to top off with as well. I can't see any reason to have a separate "top-off oil". Is that what you're asking?

Haven't reached the first change yet. Added a grand total of 1/4 quart at 400 miles. I'm at 800 now so it probably needs another 8 ounces :p

 

I would stay away from the Synthetics. There is to much wishy washy about it and rotary's. But thats just me. I use to use M1 in all of my Piston vehicles but they didn't injevt oil into the combustion chamber.

 

M1

 

M1 = Mobile 1

 

I now have a quart of Castrol 5W-30 in my trunk. Just changed my filter & oil over the weekend, and decided to convert from 5W-20, which I had been using (now at 12,500 miles)

Not sure synthetic is in my future, as I have been changing my filter & oil every 2,500 miles. The value vs. cost thing, more than an issue with synthetic vs. rotary.

 

I have also been using Castrol 5w20 to top off.

 

Cool..........Thanks for all the replies.........

seems the jury is still out on the synth in a rotary........

Pretty cool....

I know motorcraft makes a synth blend....5-20.....anyone heard of or try that...(I see it at Wal Mart)

I have used M1 5W 30 for 5K miles and the engine still runs as smooth as when I first got the car.
