Hi, I just moved to Venezuela with my 8, and here it is always around 90-100 F.

I was living in Canada and was using 5W-20 oil but someone told me that this oil was not appropiate for the conditions here in Venezuela... Any suggestiions?

Thanks

 

use 5w30?

 

Is this ok to use? I have no clue....

The other thing is I dont know if i will find that kind of oil here.... I understand the number 5 means for 5 degrees celsius, if this is true, this weather does not go below 15 C, therefore I doubt anybody would produce that oil here...
Thanks

 

I would use 5W-30. It holds up better in 100+F temps. Mazda specifies it everywhere else but the US and Canada.

I would even use 5W-30 here and do. Most users switching report better idle and mechanical smoothness.

 

Maybe contact a Venezuelan Mazda dealer?

10w30 or 5w30 should be popular everywhere, just make sure to buy brand-name oil.

What the heck you doing in Venezuela? Last I heard you were in Calgary!!??

Yeah man i moved here... remember i was from here i was just doing my degree there....

The thing about contacting mazda dealers here is that the 8 is not popular here, I have seen only 1 in like months.... they dont know the rotary engine.

What about synthetic oil? is it ok to use 10W-30 Synthetic? I dont think I need the 5w since this country will never go below 5 Celsius.... Always summer...

Thanks

 

Use 5W-30....use a full synthetic. Royal Purple. Dont use Mobil 1.

 

5 - 30 or 10 - 30 is fine.

Also, C&D is right, use a full high quality synthetic like royal purple or red line.

 

No - it doesn't stand for that. It's the viscosity rating when the oil is cold.

I don't remember the temperatures in the definition, but when 5w20 oil is cold it has the viscosity of a stright 5 weight oil. When it's at operating temperature in a warmed-up engine it has the viscosity of a 20 weight oil. The "w" means that it's suitable for winter use: it won't thicken unpredictably at very cold temperatures.

The idea with multi-grade oil is that when you're warmed up, the oil is the right viscosity (the higher number) for that, and when the engine is cold (and a single-grade oil would be really thick) it acts like a lighter oil and flows. Put straight 20 or 30 weight oil in a modern car and when cold the oil won't flow to where it needs to; you'd probably do some damage on cold starts in wintry places.

Since Mazda recommends 5w30 everyplace but the US and Canada, that seems to me to be the best one to use. In a hot climate 10w30 ought to be OK, but IMHO isn't a really critical decision: 5 vs 10 applies before the engine warms up, when you shouldn't be on it hard anyway.

thanks for the great input!!!

My last question is, is it safe to drain the oil and replace it with the synthetic one and start running like normal? Or is there any break in process for the engine to get used to the synthetic oil?


Does anybody know about the Motul Synthetic oil? Lot of people reccomended me that one for my car...


Thanks for the info...

 

You can use 20-50 if you want.

Unless someone proves the oraficies to lube the apex seal are too small for that weight you can use that or any other oil.

Check the Austrailian forumn. They banned the use of synthic oil.

Check out the recall notices too.

Check out DIY or do a search.

You have to let the oil out of the small coolers.

We got 7 quarts of oil. Need to get rid of most of it. Then change it again.

Synthic and regualr oil don't mix and will mess up your car. Do it right !

 

I don't know where you're getting your information, but thats completely untrue.

It's perfectly fine to change to synthetic on your next oil change. There's also no difference in maintenance or "break-in" (although you can run synthetic longer than dino oil, so you could go 5000-6000 miles between oil changes, but thats neither here nor there). Just keep checking your oil level every other fill-up!

 

I tried to attach a chart from the Mazda service manual. It shows that Mazda allows a lot more choices in engine oil other than 5W20 or 5W30.

 

That chart is interesting. Does the manual give temperature ranges for the various oil weights?

The engine section of the service manual I have (pdf version, supposed to be '03 or '04 US edition) just lists 5w20.

Ken

 

That chart is from (what looks like) the Europe, Australia, New Zeland and "everywhere else" service manual since those countries are mentioned by name. It's the one that available on-line. My US-UK manual only lists 5W-20 as the proper oil. None of the manuals have any temperature ranges listed.

 

Stop spreading BS when you have no idea what you're talking about.

 

Oh ****! this aint gonna be pretty

 

yea,

synthetics and dino oils are compatable unlike in the distant past when that statement was actually true (late 60's). Of course who would run them together if you could get the lesser grade dino out as was advised.

Get your head in the GAME man !! Go 5w30 something good... and forget about it.
What about Castrol, thats everywhere on the planet, I saw it.

Great,
Jeff

 

I've used 10w40 dino for the last 8K miles because of the high summer temps in my city and because I took it on a 3k mile roadtrip to texas. Seems like the car runs better. I plan on switching back to 5w20 synth at my next oil change as it it nearing fall.

 

I see summer temps of 85-95F and use RP 5w20. I had some rough idle issues on really hot days once the car was fully warmed up. In addition to the reflash, which I haven't done yet, I am going to switch to 5w30 next summer.

I'll still probably use 5w20 in winter since we can have days where the temp never gets above 10-15F. I have heard that some people have trouble getting the car fully warmed up around here.

 

My temp is around 110 to as low as 20 ? I think.

5w30 should be the best thing for all weather. Reason why its 5w20 for North america Market ? Cuz of Ford's suck *** Policy and poorly build cars. And trying to get *better* emission by using 5w20

 

I realize that 8s everywhere else in the world get 5W-30, strongly suggesting they should get that here, too.

Except, maybe, for one thing: is the ECU in North American cars programmed differently to compensate for 5W-20? If so, maybe it's better to run 5W-20 here, no?

 

The latest Flash modified the OMP part to increase a bit of oil during curising. this is very important since ameircans curise ALOT.

and Smooth out the A/C idling issue

Nothing else has changed.
