Think the synthetic recommendation will change with the RX-8?
Since the original rotary came out a long time ago, and synthetics have come a long way since then (including abitlity to burn cleaner), do you think Mazda will put out a recommendation that synthetic be used (or at least can be used) in the RX-8 motor?

If i had a Renisis motor i would still use my trusty old Castrol GTX 20w 50 motor oil. I've been thru to many Rotary's and that's all i've ever used. also the factory mazda oil filter is by far the best out for any rotary engine.

Former Moderator. RIP Icemark.
off to other rotary...
and its been proven that good quality synthetics are perfectly fine to run in a rotary... it's the crappy ones like valvoline or havoline that you want to avoid

20w50 is recommended unless you live in Canada or the Northern states and it's during the winter months. 10w40 or 15w40 is more suitable if this is the case.

Best to use synthetic in conjunction with either pre-mix or blocking off oil flow from the oil pan to the omp and routing 2-cycle oil to an omp adapter from a separate gravity-fed reservior.

Oil filters sold by Mazda are manufactured by Fram, one of the all-time worst filters.

A controlling share of Tennex was recently bought from Nissan by Mahle a good German parts company. The Mahle-Tennex filter is a good one.

Purolator filters USED to be good, until they started making them out of such thin metal that they get crushed by my oil filter wrench when installing them.
I'm STILL looking for a quality filter, but it seems that they ALL kind of suck in one way or another.

The Mobil 1 filter is pretty nice, but it's freakin' expensive. I stopped buying them when they went from $9 to 11 dollars and went back to the USA Mazda one.

BACK to the orginal topic on the synthetic oil....
Has anyone read the RX8 manual to see what Mazda says about synthetic? I don't personally care what anyone else says, I am only concerned about Mazda's stance.

Try out NAPA Gold 1182. It's application is for a Peugeuot but the thread and pitch are same as rotary and other Japanese cars/trucks. HUGE filter. O-ring is fat and wide, seals fine. Quality materials in and out.
Been using that on my rotary and Isuzu Amigo V6 and like it alot. The V6 gets metal specs in the oil and when running the NAPA filter theres less metal spec on the dipstick!
And it is an $11.62 filter by the way but worth the insurance!

First I've heard about dented Purolators. I've had no problems with them. How tightly do you do them up to produce these dents? 1/4-turn past hand tight should be sufficient.

Fine, ppl want to talk about oil filter so let's change subject.
The Napa guy told me that Napa silver is a Wix also. It's got 96% single pass efficiency with an anti drain back valve. I doubt if it's a FRAM because FRAM doesnt usually have anti drain back valve unless it's the expansive Tough Guard ($6) or X2 ($10). I think the silver is a fine piece. The gold has more paper element but since we change our filters less than 3k mi, I think the silver is just fine. Never tried it on FD yet but I may do it since it's $3.5. Otherwise, I'll stick with OEM.
