Greetings,
I was curious
what Mazda recommends for the Renesis engine now, so I did some
searching. The owners manual specifies 5w20 for all conditions, but
what do they know :-)
Naturally,
there could be a difference between the 13B and Renesis as it relates to oil,
but I'd bet money against it. I think the real reason is that oil is
better than it was a decade or two ago, and manufacturers are realizing the
benefits of lighter, but higher quality oils. Of course the main
"benefits" may be mileage, and HP, rather than longevity, but if the
manufacturer will stand behind the engine for X number of miles, you can bet
their recommendation is sufficient.
On the
subject of synthetic, I couldn't find an answer than I considered
conclusive. It was specifically prohibited in the RX-7, but again, that
could have been due to the oil injection, and the quality of synthetic oils 20
years ago. It sounds like the current recommendations for the Renesis
doesn't say anything about synthetic oil. In other words, it doesn't say
you can't, and it doesn't say you can. People are reporting the same old
tired stories I used to hear when I had the FD- "my dealer said someone put
synthetic in his rotary engine and it ruined it, so don't use synthetic
oil". Total BS as many of us know first hand.
Just feeding
the fire, while I work on my rudder.
