Greetings
again,
For my next question, what
weight of oil are you using? I'm using Mobil 1 SuperSyn, and have only
used 15W-50 so far. I don't know about the RX-8, but I know that almost
every vehicle on the planet uses 5W-30 now. I bought some 5W-30 the
other day, but still haven't decided if I'll use it, or swap it for one of the
other weights.
My thinking when picking up
the 5W-30 was to limit the resistance through the cooler, and filter. I
also understand that lower viscosity oil will probably provide better cooling,
due to higher flow, and perhaps better heat transfer. It would also
limit the initial pressures that will be seen on a cold startup. Bruce did
mention that he thinks Tracy prefers the higher weight oils for the benefit of
the redrive, since it's using engine oil, rather than the proper gear
lube. Of course, these are auto transmission gears, which don't use heavy
lube anyway.
SuperSyn comes in 5W-30,
10W-30, and 15W-50, so which would be best?
Thanks,
Rusty (drinking low viscosity
coffee)
