I'll be driving my car for week come this April 14th and realize that I should look at getting my hands on the all important 5W-20 Engine oil. I've called to three places so far and this is what I got for pricing:

Canadian Tire: $3.99/L Quaker State
Walmart: Don't carry that grade
Costco: Don't carry that grade

Please list the places you buy your oil with prices and size of bottle. This will benefit us all in the long run.

3M protection, group rate anyone?

I'm getting a group rate for the 3M film protection for the car as well as tints as well.

Walmart: Pennzoil $3.99 (1litre)
Castrol GTX 5W-20 (greyish cap on bottle) $3.49 (1litre)
Castrol GTX 5W-20 (greyish cap on bottle)~$14.00 (4.4 litre) <- I'll check exact price and get back to you as I just picked some up this weekend.

Zellers: Quaker State 5W-20 $3.89 (1litre)

 

I get Castrol 5w20 when its on sale at K-mart ($1.30-1.50qt)....

 

Where is there still a K-Mart in Canada? Also, my local CTC doesn't sell 5w-20, I checked today.

 

I couldn't find any decent 5w20 in the Edmonton area so I'm using Castrol synthetic 5w30. I figure the European RX-8's call for 5w30 so it can't hurt to use it in North America, plus its easy to find.

 

I've been told that synthetic is a big no no for the car, but if it works what the heck

FWIW: I was at an Esso gas station today and they have there own 5W-20 oil there and it was $8.99 So Stay well away.

 

5w30 sure
Synthetic, not so much.


Personally, I buying my oil from the dealership.
I'll be damned if I'm going to call all over town to save my self $1 between oil changes on the 1L of oil I use (what's that, like $4 a year?)

 

So here is what I found out thus far for the oil prices:

Walmart
Castro GTX 1L.........$3.46
Castro GTX 4.4L.....$13.84

Pennzoil 946ML........$3.97

Tech2000 2OL.........$59.60
Tech2000 1L.........$2.98

Canadian Tire
Quaker State 1L......$4.99

Shell
Pennzoil 946mL.........$4.49 (I could be off on this one, but will make
adjustments as needed.)

:D

... I know the manual and the oil cap specifically specify 5W-20, but i'm using 5W-30, is that ok? Or should I change to the 20 immediately?

At least I'll know where to look now for good prices

ooops, it looks like this was already answered...

 

You should definitely NOT use a synthetic oil...the rotary requires a mineral based oil that will burn in the combustion process. Synthetics tend to "gum" and can cause apex seal failure.

You should do a little reading in the tech forum and other areas of this site. It has been stated by Mazda that it's ok to use synthetic in the RX-8, the manual doesn't even say not to use synthetic, only to use the proper spec oil. I could link several threads to this for you but I'm pretty lazy, a search for mineral vs synthetic should give you all the info you need to clear up your misconception about the renesis and synthetic oil.

 

I also picked up 5w30 (synthetic). Except I chose Mobil 1. It should be fine.

 

Petro Canada is the maker of the oil mazda canada distributes to the dealers.

I can't remember the exact price but it wasn't outrageous and there isn't any worries about mixing brands at that point

 

Avante Mazda sells their oil for $3.35/1L. Who knew?

Ditto to what Jag said - what you've written above is complete nonsense. Synthetics burn cleaner than mineral oil, it's mineral oils that leave sludge deposits from wax content (there's zero wax in synthetics). Mazda requires that you use 5W20 or 5W30, API spec SL - that's it, no restrictions about synthetic or not.

Again, as Jag mentioned - this has been extensively discussed on this forum for over 9 months, and the rumours about synthetic problems have been thoroughly debunked.

Regards,
Gordon (a committed synthetic oil user, because it's better!)

 

If you have questions about type of oil, syn or not, check out the past threads, or go further and ask mazda canada. Just make sure that you are satisfied with the answer.

~$43-45 for 12L (12 1L bottles) of oil...from Mazda dealership...go for it or not?
