where could you find them? any place carry a lot of oil brands? I could only find 5W30, 10W30 mobil1 at canadian tire haven't tried lordco but I dont think they carry mobil1?
yes... I'm making the leap to synthetic soon

Gord96BRG

Canadian Tire here in Calgary now carries Amsoil, and I believe they had a 5W20 on the shelf. However, it was over $12/litre, compared to under $7/litre for Mobil1 or Syntec. I've used the Castrol Syntec 5W30 in my RX-8 twice now, and I'm fine with that viscosity since Mazda recommends 5W30 everywhere outside North America anyway!

meh i got coupons for 5 free oil changes :D

Enzolor

How? Where? How? =(

BIU

you sure you are gonna go with synthetics?

im gonna stay with the normal dino oil because i am yet to be convinced that synthetics is good for the rotary engine..

Rotary Titus

well I've read all the threads here on synthetic, guys like royal purple say it's ok for the engine and even mazda specifies it in europe.... and plus synthetic is always better for the moving parts anyways and since the 8 likes to rev so high, synthetic are better for holding together at high rpm applications?
I found mobil1 0W20 today (says formulated for 5W20 uses) at Canadian tire but there's only 3 bottles left and I had to hunt around for them!
will let you guys know if my engine blows up :D

BIU

lol KABOOOOOOOOOM :p

Gord96BRG

Absolutely positive that synthetics are not just OK, but better for the rotary than mineral oil. I'm betting my engine on it!

ooo engine up for grabs


and my cousin was the sales manager at metrotown mazda
so he just threw them in my complimentary rx-8 bag

Enzolor

Who's your cousin? I bought my 8 off Metrotown Mazda last week.. dealers were not exceptional.

Rotary Titus

so I changed it today LOL I tried to do it during the day when it was sunny at silver city richmond's huge parking lot but as soon as I was about to get underneath the car, a guy with riverport groundskeeping came and told me no I can't do that on their property even though he did really like my car, I don't think offering him to test drive would've made a diff :p
so I went over to my friend's place and used her backlane instead which had a nice incline so I can get the car tilted to get as much oil out as possible... everything went good except read my thread in the tech garage about the oil filter
maybe it's just placebo effect but I feel the engine being so much smoother now, when I first started it back up and hold the clutch down (to get rid of the annoying throwout bearing noice), ALL there is is JUST the electric buzz of the rotary, no valvetrain noise no nothing! it made it sound even more like an electric motor now. but maybe it has nothing to do with synthetic would be just a new oil change

fietguy

hey RT, did you ever find non-synthetic oil?

and if so, where did you see it?

Inconsequential

odd, when I went to the dealer asking about synthetic, they said that it eats away the apex seals faster, but they scoulda been bsing me

Rotary Titus

fietguy what do you mean? like did I find regular oil?? ummm well yea they've got them everywhere! if you mean non-synthetic that's 5W20, then I bought some pennzoil from lordco, I believe they have non-syn castrol in that grade as well

here's a thread form the tech forum, a letter from Mazda NA Parts business manager
https://www.rx8club.com/showthread.p...5&pagenumber=2
so it seems a lot of ppl including dealers are confused that there are CHANGES made to the new renesis engine from the previous versions

Doctorr

In Canada, good 'ole WallyMart sells two or three brands of 5w20.

It IS expensive though, around $4 a litre, because it is a synthetic blend. (It is difficult to make a5w20 oil that will 'stay in grade' over time, without using synth.)

So if you go the full synthetic route, you are probably only raising your oil costs, but certainly not hurting your engine.

(Eats the Apex seal.......thats funny!)

yeah, well, that is what the dealer said, and you know them, which is why i mentioned it, to get a better opinion. Glad they are wrong

Enzolor

Canadian Tire, Kingsway is getting some Quaker State 5w20 this week sometime. I've been hounding them to bring some in.

No luck finding Castrol GTX anywhere.

fietguy

Hey RT, the Mazda letter says there are changes to the renesis engine but that it is still recommending non-synthetic oil...

I actually made up my mind before this letter anywhere from what I read and the people who I know who have had rotary engines before, I will not be using synthetic oil in mine, at least not for the break-in period of the car....i really believe synthetic oil does not allow the apex seals to break in properly so those are my reasons....

I also use use 89 octane in my car by the way, some people might suggest to use 94, i guess there are different opinions to everything...

thanks

Rotary Titus

I see..... yea I've heard about not usuing synthetic for the breakin period from friends about piston engines as well but I've already logged 10,600kms on mine so I guess that should be ok past the break in period
hey same here! I've started usuing 89 once the 94 prices were a dollar something and I've noticed no difference at all.... plus the manual does say it REQUIRES 94, so might as well get my money's worth for my extended warrenty :D

Enzolor

Your manuals say Octane 94? Mine says 91.

Hmm.. sounds fishy

fietguy

yeah i think the 91 is whats listed...but its kinda of a 'loose' recommendation, they say 87 is fine but with reduced performance...

i have not experienced any engine 'knock' all the way to the beep, so why would I have any purpose for a higher octane?

so i just go with 89, and i think my car is lightening fast.....

fietguy

hey man, if your past 10K anyways I think your seals are prolly broken in, i think even the most hardcore dino user would say at least you didn't break it in with synthetic oil...

which leaves me to wonder, anyone know what type of oil Mazda puts in their 8's when new?

is it their own brand of oil?

Gord96BRG

That's not from Mazda NA, it's from Mazda Australia...
