20w 50 for rx8?

Don't know what manuals you're referring to... the us one says to use crappy 5w20, in europe the recommended viscosities range between 5w30 and 10w30.
I always used a good 10w40, even before changing my oil system's pressure.
Malta is very close to italy, 20w50 is definitely too much both climate and oil system capabilities wise.

I use 10-40 myself I think if you're in a place where the temp will reach over 37.7 C I don't see anything wrong with running 20-50 I've used it before during the summer months with out any issue I live in southern california so temps in summer will exceed 37.7 C (100 degrees F) so I sometimes run 20-50, but if it's mild there I think 10-30/10-40 should be fine.

Yeah, that looks like it. I wouldn't listen to the US version.... 5w20 is garbage for rotary. I always used 20w50 in my FC's year round with no issues.
I used 5w30 when I first got mine, but at 300 mile intervals for 900 miles to help get kind of a flush since the original oil looked so bad. After that it's been 10w40 for about 10k miles now.

Yep I have been using 10w40 since I got the car at 18k miles also. Seemed the best choice based on the little chart and from reading on here. Now I am at 37k miles and still running great(knock on wood).

u mean it's hard as hell when dry ?
FC has weaker oil pressure regulator but still survive the 20w50. all year long.
I use 20w50. 15 degrees a month ago. no issue. Well, a GOOD Synthetic 20w50. Not some Autozone junk

I'm in the US and my manual says to use good 5w20.
Besides that page from the Australian owner's manual, one edition of the shop manual lists all of those oil grades without even specifying temperature ranges. No wonder everyone argues about which to use!

You're right, typo on my side! It's our manual that states to use 5w30

In the summer in florida I ran 20W50. 5w20 turns into water. 10w40 even gets thin. had over 110k miles on my 2004 rx8 before that engine was replaced after an accident, still ran awesome and had good compression. Make sure you premix though. the thicker oil doesnt inject nearly as well.
